What hack said to cope with a grinder?

| Posted in Construction Techniques on
Because whoever it was I owe a hearty “Thank You” to. Man, I don’t know of any technique I’ve learned in the last several years that is as great and time saving as this one. Especially for a new guy I’m training who was having a rough go of it with the coping saw.
When I heard this advice I really did think “hack”, but that’s why this place is so great, tons of very reliable information.
Thanks to everyone who contributes here, but especially for those beating the coping with a grinder drum.
Peace,
Casey

I gotta admit, I opened this up to see who was diss'n me.
I didnt discover this way of coping but I'll show it to everybody like it was my idea!
I started back to work here in Iowa and have made a convert out of the guy I work with. He'd spend all that time with his coping saw and see me do it with little to no effort in about 1/10th of the time. It wasnt long before he was over to borrow my grinder.
Doug
EDIT; One thing that every body that does cope with a grinder, or for those that will try it, Not all grinding disks are alike.
I recently could not find the disks that I normally use so I tried some of the DeWalt disks.... they suck, PC....suck, tried some off brand ones from the big box store, they suck even more.
I had to go back to KelWelCo/White Castle to get the good ones, hated to patronize a store that seams to have switched to its mother stores(Home Depot) practices but ........They have good grinding disks! I bought a boat load of em, never know when they'll switch to the off brand of the mother ship.

so...what disks do you like?3M?
Another vote of thanks Doug!
I'm using the grinder for touchup using a diamond wheel.
I remember it being you that introed the technique here...
what do you think of the Norton brand..Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming<!----><!----><!---->
WOW!!! What a Ride!Forget the primal scream, just ROAR!!!
I dont care for Norton brand but need to go out to the truck to see what brand I actually do buy. The comment on Norton is more my feelings on there sheet paper so ............
It's cold out so I should be right back!
The disk says "SAITDISC" on the back, made in Italy. You know those Italians are known for there superior grinding disks!!!
I use 24 grit for heavy duty stuff and 36 grit for softer wood.
The Dewalt brand is almost dangerous! The damn grit comes off and flies up in your face, cheap azzed crap. Same for the PC.
To be honest I dont know that I have used Norton discs. Probably not fair to say anything either way on them.
Some of the cheep discs dont lay flat and are out of balance. You'll be grinding and the disc bounces all over the place, kinda hard to do a nice job with that shid going on! These discs that I buy lay flat on the rubber backer and cut like butter. I notice the cheaper disc gum up quick and loose that cutting edge real fast.
Doug
I have the SAIT, Prefferred and Norton on hand both brands in shouldered and tapered edge...
I like them all but for some reason I grab the Nortons 1st...
Airgas has a huge selection of them from everybody......
The DW's and PC along with the off shore crap are a waste of money and totally suck...... threw them away in short order...Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming<!----><!----><!---->

Here's another tool that I think would work for coping -- an an alternative to the angle grinder. http://www.makita.com/menu.php?pg=product_det&tag=GV5000I've had one of these for years, which I first bought when I was helping someone paint a clapboard house. Since I had it around, I have used it for any number of grinding tasks. With the right disc, it even works well on metal. I haven't tried it, but I betcha it would work great for coping, and it might be a little easier to handle than an angle grinder.Ihave a baseboard coping thing coming up in the next week, and I am going to give it a try.********************************************************

nikkiwood, I noticed the speed is 4500 rpm on your sander, which may be easier to control and a little slower. I have a Makita 4" angle grinder now and the thing I dont like about it is the single speed, the high rpm (11,000), and the way it jolts when you hit the switch. I have only used it for grinding and cutting steel. I havent tried it for coping yet, but I am thinking I would rather use something with a variable speed for more control and slower starting. I looks like your sander is a single speed, so at 4500 rpm that might not be an issue anyways To me it wouldnt matter if it took 30 seconds to do a cope rather than 15, if I was more comfortable with the tool and maybe a little safer to operate.
This sander is really a tool for house painters -- mainly for prepping clapboard siding. It sands aggressively, but is still easy to control.I will give it a try today for coping, and see what happens. As you suggest, it would probably work better if it had a variable speed.We'll see...............********************************************************

I dont know anything but it looks like its a two handed tool. That wont work if it is .
Well , Ive put it off long enough. Ive rigged a 4 inch up and I need to try it today and the 4.5, but Im guessing I will like the 4 better holding in one hand , maybe not .
Tim
If you're going to use an angle grinder for coping, I would strongly suggest you get set up so you can clamp the work piece -- so you can keep both hands on the grinder. Not only is it safer, but you'll have better control over the cut. As you have probably figured out, you have to take the guard off the grinder, so I would not risk holding the work piece in one hand and the grinder in the other.********************************************************
"It is what we learn after we think we know it all, that counts."

Ok, I just saw your other post. I usually hang on to the grinder with both hands anyway so the clamping is the way to go. Thanks.
I have been using a jig saw for over 25 years and would like to try the grinder method. The blades I use in my jig saw are very fine, ground much like a saw with no set and are back beveled.Anyone have an opinion about the grinder vs the jig saw?
Edited 1/16/2007 2:50 pm by gb93433
"Anyone have an opinion about the grinder vs. the jigsaw?"
I do!!
Once I started using a grinder I figured out that there is absolutely no reason to ever go back to using a jigsaw. The grinder is twice as fast, more accurate and has the added bonus of giving you the ability to "touch-up" your copes. you can't do that with a jigsaw.
Once you've tried a grinder you'll see what I'm talking about..... "Come over to the dark side with the rest of us."
Anybody wanna buy a collins coping foot?
Mark" If I were a carpenter"
One of the worst injuries I have seen came from an angle grinder -- guy was one handing, grinder snagged, cutting wheel jumped into his arm. So I don't have any trouble with the hassle involved to clamp a loose piece.......... <G>********************************************************
"It is what we learn after we think we know it all, that counts."
John Wooden 1910-
I have a small table I use with one of them adjustable Kreg clamps on it. There is a strip of wood on it (like a fence) and the clamp is next to the fence. The clamp will hold the trim in one easy motion. The clamp can be moved to a notch on the other side if needed. Not a hassle, and much easier than holding it. The only drawback to this is its one more thing to load up and set up. I made it for use with Kreg jig so its used in the garage more than anything. I usually just clamp the material to the support on the miter-saw stand on the smaller jobs.
Edited 1/17/2007 8:55 am ET by wood4rd
I leave the guard on the grinder. I put the work piece on my table saw against the fence and apply pressure on the piece with my left hand and extend my left thumb out to the guard on the grinder to guide it along...never felt a need to clamp anything down.I'll take a picture tomorrow.
Yeah ....... sounds like a good way to do it. would like to see a pic.********************************************************
"It is what we learn after we think we know it all, that counts."

Here are three pics of the process I use to cope (with the table saw fence a backstop and guiding the grinder with my left thumb):So far, I've managed to avoid grinding any grooves in the table saw. ; )
The pics are great.
The coping looks easy, I would have tried a different angle of attack, not knowing.
What really puzzles me tho, what were you holding the camera with - your tail?_______________________________________________________________

The power switch makes a huge difference, one that turns on and stays on works best. You can then easily hold the molding with one hand and hold the grinder up higher, nearer the head, for good control. The wood cuts like it isn't there. Its not like grinding steel.Nobody is as good as they seem, nobody is as bad as they seem either.
Glad you liked the pics...they were taken by Mike the painter, a great guy--who makes my work look really good.
That's a very slick way to do this..... better than a clamp. I'm guessing you have two back-to-back discs on the grinder, right?It would be nice if you could tuck those pics away, and trot them out everytime this topic comes up -- which it seems to frequently. Thanks for taking the time.********************************************************

Glad to be of service. I learn more here than I contribute...not that anyone is keeping score : )--"I'm guessing you have two back-to-back discs on the grinder, right?"Yep. Two 3M disks I got at Menards.
I've never tried it with the GUARD!...tried the back to back once, way too flappy...gotta find something other than walmart disks<G>We just spring clamp the pcs to an ancient straight, flat, and light fir 2x8 that came out of a reno...been hauling it around for years.Gotta make some support legs for a granite bartop next week.

Snort,With the grinder spinning down (so I eat less dust), she wants to climb...so the thumb on the gaurd resists the grinder's tendency to climb, and gives me really good control.I use 3M disks...SandBlaster IIRC.The bar sounds nice, post some pics if you get a chance.
http://www.makita.com/menu.php?pg=product_det&tag=GV5000I tried it, and this sander doesn't work for spit on coping. It's way too slow, and it burns the wood (scrap of maple crown). I used a 24 grit disc. The angle grinder is faster, easier to control, and does a better job.********************************************************

thanks for the info, now I'll have to try out that Makita angle grinder and that might be one less tool I have to buy. BTW, you guys dont clamp it down but just one hand on the trim and one on the grinder? I will probably clamp it down, since have never done it before. I was just starting to get the hang of the coping saw too. Clamp it, just saw your post.

Carps didnt use to even own a grinder. I would never see them in a tool box or being used. Ive got 6 of them and use them for different things. Its one of those things you have to wonder how we did with out them. They were there all the time werent they or was that the big ones?

I use a cordless Dremel. It weighs little and stores in your belt.
I've seen guys use the dremel but can you cope the backside of 3 1/2" crown in 15 seconds with a dremel or 25-35 seconds for 6-7" crown?
I'm not knocking the use of the dremel but it seams about as slow as the cope foot for the jig saw, and thats slow! I dont enjoy coping enough that I want to spend a lot of time doing it.

I (and a couple of other guys I work with) when we have a really richly detailed piece of molding "draw" the line of the cope with a Dremel to get it precise and exact and then remove the bulk of the material with a grinder.

BTW, I mentioned using the same set up to fit a counter top to a wall after scoring it. I use it for a curvature plane . They kept talking about other ways though. Same thing as you , 36 grit for the rough fit and finish to a sharpened pencil line with 80 to 100 grit. It even back cuts it so the finsih is against the wall so I guess its a cope isnt it ?
Tim

I've been useing the grinder to do counter top fits to walls for a while now, so much faster then the belt sander.
I can clean the line up with the grinder pretty well though, sometimes I need to hit it with the hand plane but thats not a biggie.

Hey Doug.
Just found this thread, Let me jump on board the "give thanks to Doug" Bandwagon.
This is the best method of coping trim that I've ever encountered. Once again I say.. "anybody wanna buy a collins coping foot?" I literally will have no use for it again.
Of course I'm sure I've told you how I scribe laminate countertops. I use my router with a 1/2" mortising bit to take off the lion's share of the material, (usually I take it to about 1/8" of the line). Then use the belt sander to finish it to the pencil mark. This method scares the living daylights out of everyone who's ever seen me do it or listened to me describe it, but so far, I've done literally hundreds of countertops and I have yet to have the router "get away" from me. Still, it's not something to be attempted by the faint of heart. You have to keep a death grip on that router and have the focus of a neurosurgeon. You cannot let your attention wander even for a moment...." If I were a carpenter"
Mark
You probably know or at least met some of the guys that taught me the coping with the grinder method!
For me it came out of IC/CR, doubt thats where it originated, after all were just a bunch of dumb farmers!
I'm not even going to tell anybody on here how I use my routers, the safety police will have me kicked off this place!
Doug
you know the method I was using is null and void now...

That gives me a 4 and 4.5.
Now Im gonna have to test both on copes.
Funny thing about all this ;
I work on old stuff all the time and just got through remodeling an older house .[50 s model] I could not replace the trim with out making it so I was careful and I pulled enough out of a closet to make due . I had that sander out all the time and kept it hooked up to clean up trim. I ran some new crown and used a coping saw with it laying there close by. Hmm.
Thanks for the thread.

I may be the wrong one to ask Marty.
Im a collector of grinders.
I forgot one I bought at auction. I have 7 grinders .
When I entered the grinder world it was by fluke . I saw a drywall finisher sharpen his floor scaper in an instant. He proudly stated he did his lawn mower blades and shovels? Post hole diggers and the list went on. He told me he sharpened his riding lawn mower blades still on the mower.
My Brother took a bunch of trim off a house and chose a grinder with sanding pad he bought new for that job. Then he said hes found do many uses for it ,..
I had a rough house to scrape and paint and tired of it basically because it was so hard . I got whizzed of and bought a 4.5 and found the rubber disk backer, plus a bunch of sanding disks. The paint just fell off easily and then I found I was using too rough a disk , gulp.
It was my house so screw it . I went and bought some more and developed a way to do it smoothly.
Once I owned it and it was in the truck , I used it to even up cornice trim on corners. I found then it would plane rather quickly so I tried it on counter tops .
That started the buying with a 4 inch fitted to a cutting wheel full time. Makita.
Then I bought the six pack from Dewalt which had the 4.5 grinder in it . That and the 4.5 are my main grinding tools . Sand papaer on one and a cutting wheel on the battery. I de plumbed a whole house with them. I cut off rusty toilet bolts and every thing under sink that doesnt want to come out . I cut nails all the time flush off trim and reinstall. So much quicker than snips and pulling .
The lists keeps building and I didnt mention every thing . One thing I will mention on a hardwood floor last week the battery snipped all the staples from the carpet pad . Fast .
Now I gotta try this coping thing . <G>
Tim
Amen Tim, I have at least 5 counting. The battery job is just for cutting counter flashing on chimneys and such, and touching up my soldering rig tips...
All the others are equipped with various cutting/grinding/wood hogging type attachments. At 17.00 a PC from HF and infrequent use, I can buy a boatload and never wear one out.

Specifically, what grinding wheel do you recomend?
Thanx,
Chuck S.live, work, build, ...better with wood
Throwing my two cents worth here, I started using a grinder for coping after reading about it in FHM, I think. I use a good Sears 7 amp 4 1/2 grinder with a switch that will stay on until bumped. It works like gangbusters with the sanding disk. You may have to buy something to adapt to the disk if you did not get the kit to begin with. Another great use for the angle grinder is using the cutting wheels, this thing saves my bacon every few months for cutting metal, even hardened.
Handymanvan.
I have several Right Angle grinders (2 AC/ 3 pnuematic) but don't know what wheel to use that won't load up when grinding wood.
Chuck S.live, work, build, ...better with wood
You must be a metal worker too--that is where I started using these things. You do not use a hard metal grinding wheel, get yourself some round very flexible sanding disks. They have the texture of a course shingle. You might need some adapters to get them onto your arbor. One piece will go on then the disk then a cup to hold the works together, sometimes I put two together front to front for stiffness or front to back to grind going and coming. There is also a backing plate you can use, although I never liked mine. As for metal work, these sanding disk will sand rust and welds easier than a hard wheel in my opinion-for great smoothness. If you try to use a hard grinding wheel on wood, and I have, the pitch will clog the wheel and start burning the wood. If you do sheet metal too, try them on that, might be suprised.
Thanx,
I will check that out.

You have to have a rubber back piece to put on your grinder, you can get those at a tool store and probably the big box stores. I believe I got mine at Menards.
I've heard of guys using two disks, back to back, so as to cut both ways, I've never done it but I can see how it makes sense. I would assume that in the case of two disks you wouldnt need the rubber backer piece.
If this doesnt come across clearly let me know, I'll post a pic of it tomarrow.

edit; I see where your asking about the wheel. You may be thinking in terms of the hard disks, they wont work. I'm using 24 or 36 grit, very coarse in terms of sanding! There bendable. They build up but not all that fast.

I bought one of those once but misplaced it and never did try it out!
Do those come in grits of 24 or 36?
If not they probably wont cut the wood fast enough.
Doug
Yup 24 thru 220..
so yur using a different set up???Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming<!----><!----><!---->

Different setup.
Yes.
I have a flat rubber wheel with the disk over that. I'll take a picture of it when I go out to the truck later.

Doug, I used a slew of the flap wheels Marty is referring to, to strip down my logs here. Very hard white oak w/paint. And the occaisonal old lath nail. They work great on wood, and are stiffer, and also will sorta cut with the edge, like a cut-off wheel.
Often use one on roofs where a solder joint busted, to clean up the oxidation so new solder will take. They last almost forever. I get 3 packs from HF for about a buck a pc.
The blue Adalox are about the same, just cost more.
When I was doing the logs, I employed 3 grinders..one with a chainsaw wheel for carving out the punky wood, one with a flexible ( like you mean) sanding disc w/ 36 G, and one with a 60G flap grinder. Saves a lot of changeover time. I Lacquered right over the 60G surface, cuz as the flap wore out, it burnished nicely.

Go down the line in this thread, I showed pictures to Nikki on how I set up my grinder.(edit, actually you have to back up a few posts to see it!)
BTW, the only way that I could do copes with a grinder is if I had a touch/toggle switch, those flapper switches dont work for shid, you have to hold them all the time and that prohibits me from turning my grinder certain ways.
I gave my Milwaukee grinder to Luka cause it just about took a leap over a bridge, the paddle switch hates me!

see my post to Nikki. I walked right into Menards and bought what I pictured in the post. I'm sure you could do the same at HD or Lowes.
Doug
Ive got the same thing you do but I dont remember how I got it . [rubber backer on a 4.5 inch grinder]
I tried to hook up a 4 inch grinder the same way and couldnt get her done . I thought the smaller grinder would be a little easiar to hold in one hand . I noticed when I did this I didnt see any 4.5s either .

I dont think I could find 4" disks, never seen any. I see what you mean about control though.

Here is a few pictures of my set up, I walked into Menards and bought this off the shelf.
If your pads are not setting as flat as this one you'll incounter problems with it while grinding. It wants to viberate/wobble and that makes it difficult to get to the inside corners on a cope.
I havent tried the back to back disk method but I think I'll give it a try on the next house. I'd assume that you wouldnt need any rubber backer if you went that way.
Imerc suggested the flapper wheels from Norton, I dont know how well they would work because I dont see how I'd be able to get those inside corners that I mentioned earlier.
When I cope with this method I'm not cleaning anything up afterwards with a file/rasp/sandpaper, I'm getting good fits right from the grinder, I think thats a misconception from some on here. Thats not to say that I dont have minor touch-ups to do at times but for the most part I dont have any. I spend on average for 3 1/2" crown maybe 15 seconds for the intire cope.

--"I havent tried the back to back disk method but I think I'll give it a try on the next house. I'd assume that you wouldnt need any rubber backer if you went that way."You will like the "back to back disk method." You are correct, no backer required.I just coped a couple dozen joints for base on Friday. I line up all the right and left copes together and go at them from the left on the right copes and from the right for the left copes. Nice not to have to flip the grinder around.Maybe I can take some pics this week.

I can see the advantage of using the two disks, matter of fact as I type this my head is wraping itself around the idea!
You wouldnt have the sawdust flying up in your face when you have to reach into an area backwards to get that last little bit of wood cut out.
This will definitly be on my "todo" things tomarrow!
Doug
Careful Doug , it sounds more dangeous.
Tim
Careful Doug , it sounds more dangeous.
I've bumped my hand against the grinder a few times, leaves one hell of a rash, But I doubt it will cut a finger off!
Doug
thanks for the helpful pics. the only thing I couldn't "see" was whether the backer disc is rigid, or does it have some flex to it? I would think a hard disc that doesn't flex would be preferable for coping, right?********************************************************

Wrong, that backer is rubber, very pliable. I want it to flex. If that DeWalt thing that you posted a pic of is rigid I wouldnt want it.
If it was rigid I doubt that it would follow the contours of the piece of moulding. When I do crown, (if you see the videos that I posted last summer) I can move the disc into a curve and the flex in the wheel will force the disc up into the concave of the ogee, sorta helps in that if I had a rigid disk I would have to have enough control on the grinder to do that, something I don't have! My hands shake like an alcoholic without his drink!
I can force the disc up to the area that needs to be cut and the flex of the wheel does most of the work, my eyes do the other part! All I have to do is back off the grinder at the right time.
I haven't ever done this with a rigid grinding wheel but I cant imagine that I would get any where near the clean cut that I do.
I think you could over think this process to the point of driving yourself nuts, hell just pick up a grinder and do it. Sometimes I'm glad that I don't have to evaluate this stuff in my mind to satisfy any curiosities, I see it done and repeat it. I don't figure we're saving any lives here so what do I have to lose! About the most you could do is waste 50 cents worth of trim, no big deal.

I wasnt raggin on ya for asking the questions, hell I like sharing this, thats how I got it, but I've noticed that you analize tool purchases, methods, and techniques to a certain degree. Thats not wrong, not suggesting that it is.
I dont do that, its not within me, I just try it, buy it, use it or not.
I dont know if you have coped with this method, if not then you should try it. I'm sure that I do it different then others, you have to figure out what works best for you.
By all means I'm not giving ya crap for asking the question, I'm not that articulate, I learn from seeing, not reading, that makes me different then you or most other people.
Most times I dont know wheather or not I give enough info for someone to understand what I'm trying to convey.
I know that I have ADD, probably some dislexia and probably not all that high of an IQ so I dont do in print what I can do in practice, I expect everybody else to be like me!!!

Well, a very good friend once said to me with a grin ....."when you're done thinking about it, I've already got the job done."So I am a ready-aim-fire kinda guy, rather than ready-fire-aim....With my friend, the end of the story came when we were going to do a cut-out in the wall for a kit/dining room pass thru. We marked it out, he put a long blade on the recip and was getting ready to saw away.I stopped him , and suggested we really ought to strip away the plaster first, to see what lay behind the wall......When we found all those wires, I'll never forget that twinkle in his eye and the grin across his face.............********************************************************

Doug,
Thanx for the info. I sometimes have to cope one crown profile into another. (Stain to paint grade) I always recommend a corner block or some sort of transition, but on T&M jobs the customer is always right.
I saw something on TOH years ago, and Tom Silva was showing Norm a coping machine that was a lot like a copy cat key machine that all hardware stores have.

Well , now that you guys have caught on , I guess now somebody will figure a way to market it and make millions! I started using a grinder about 11 years ago when I saw the guys in a stair shop using it to grind rail fittings before hand sanding the connection joints . Once comfortable , it revolutionized my rail fitting technic . We used a 4" Makita or Hitachi , but after years of use , and searching for a smaller disc to help in tight places , I found a 3" and 2" backer pad at a family owned shop that sells sandpaper products . I found that a Riobi 4" grinder is comfortable , light , & cheap . I had to re- tap the threads of the backer pad nut , but now I can twist it on and off with my hand as well as the twist on sanding disc I use . I 've never seen any one else using my idea , but everybody seems facinated with it . Oh , yeah , it works great for coping , too !

This has me thinking about where my knowledge & skills come from...I can claim very little as my own inspiration. Even when I think I have a new idea, in most cases someone has thought of it before. Our man Benji saw the rail fitters using a grinder before he tried it. "We stand on the shoulders of giants."I owe thanks to Doug U and a few hundred others here. The exchange of ideas here is fantastic and helps to make up for the lack of real apprenticeships these days.I owe greatest thanks to Larry Mastbergen of Fort Collins, CO. He is a trim carpenter who was my mentor, though he might not know it. I watched everything he did, he had no secrets and was good at explaining things to the new kid. He did the best work I have ever seen...hmmm, like Doug U., Larry is from Iowa.Hey Doug, know any Mastbergens?
Hey Doug, know any Mastbergens?
Never heard the name before. I think that its just good Iowa breading is all!
Like you Basswood, I can claim no original ideas for my own, well at least when it comes to woodworking, I have a few ideas that I think are original but I'm not sharring them here!
I owe a lot of my skills to a lot of people, most will never know my appreciation either. I think thats why I feel compelled to share what I know with others, someone did it for me and I'd like to pass it on.
Besides, it's kinda cool showing off a new discovery!
