thanks,
brian

Prescriptive codes don't address the connection at less common angles, so base the connection off more typical ones using bolts, structural screws, blocking, and steel tension ties.

Use any sized straight bit with a collar added ot the router 's base. Since the collar adds 1/8th inch to the radius of the "bit", make your jig/template with 3/4" radii in the corners (add 1/8th inch to all edges of the size of the hinge). 5/8th + 1/8th for the collar equals a 3/4" radius on the jig. Meaning, if you want the finished hinge mortise to be 1.5" by 3", make your jig cutout 1-5/8ths" by 3-1/4" with the corners having a 3/4" radius.
That is, assuming your collar adds 1/8th inch to the radius of the bit, which is what my PC set does. The margin varies based upon collar size.
Gosh, I hope that makes sense to you. After reading it, I'm even confused...
i use a stanley steel hinge mortising template, so my jig corners are always square. the router bit diameter always determines the corner radius (ie. a 1/2" diameter straight bit delivers a 1/4" radius corner and a 1 1/4" diameter bit would deliver a 5/8" radius corner). i need a collar for a 1 1/4" straight bit.

Anyone have a good source for oversized collars? I find myself hampered by not being able to replicate 5/8" radius hinges. Have Bosch hanging kit, etc., but all suppliers in my necko' woods use 5/8 radii. Been waitng 5 days on current job for two new doors (sent wrong swing twice!), and I'm to the point where it'd be cheaper to hang em myself rather than lose any more production time...
Just your average former lurker...

Why are you guys using radius'd hinges? For under $100 I bought the Lie-Nielsen mortise plane, which will give me square corners, do
lock and strike mortises, and requires only a square, a chistle or knife, and the means to twirl screws.
Set-up time for one door?
Set door on edge.
Measure and mark.
Cut stops.
Mortise.
Doing several? Stack and mark at the same time. (check what the hell you're doing first... nothin' like six wrong mortises... and explains where the 35 1/4" wide door came from!)

George how does that plane do with oak?
Joe,
They say lightning dosen't strike twice. . .
Let's hope so. . .
The LN butt mortise plane can handle oak, like any plane, chisel or knife, just needs to be sharp.

Joe, I'm late to the party... "what they said" will do.
I'd be concerned if the grain was "wild"... or knotty... but you may get tearout or blow up the knots with a router as well.
Keep the L-N #40's blade sharp-sharp-sharp, and take a few swipes to do the job... either narrow, or re-setting the depth.
I'd rethink my position if I had say... 20+ slabs to do today... with
two other guys working... but(t) I don't, and find this little plane near perfect.
(It can't go for coffee, nor does it have a built-in bottle opener.)

Think of it this way, no fumbling around for the right collet. No tripping over extension cords. Not having to worry about your supplier having the replacement bit in stock after a while. No fumbling with template set up. The Cost is probably less then the router, template and jig, and takes up less space.
Yeah, I like the look of square corner hinges better, too. I use an antique butt hinge template and a 1/2" straight bit. Then finish the corners with a spring loaded corner chisel. I'm sure you've seen them, maybe 1+1/2" tall so it fits handily into your nail belt, pull it out, place it, whack it, and you have perfect square corners every time. For some reason radiused hinges always look cheap to me.
Bosch make 1 1/4" mortising bits and 1 3/8" collars to use with their hinge templates - won't do any different job than a 1/2" and 5/8" collar, but it's the one they recommend..

I use a templaco template which comes in different radius's. They have one with a 1/4 radius and one with a 5/8 radius. I use a mortising bit in my router for routing its simular to a straight bit but is designed for mortising. If you want square hinges then use the 1/4" radius template and a corner chisel to square up the mortise. hey it works for me....

Please, would you like to re-think that one?
?? cuts as cleanly and accurately as the the 1/2 and 5/8 set-up you use when you're going to square corners ? What am I missing ? .

Et al,
The two graphics below will help illustrate the point.The first show how the cut is made with a square template with a 1/2" cutter and a 5/8" collar.This one shows the same cutter setup, but with a round template with and 11/16"R fillet.

Of course, the Bosch has square corners, unlike the Carey, which has filleted corners and cuts a 5/8" radius with a 1/2" bit (the Bosch cuts a 1/4" radius with a 1/2" bit).

Not trying to pick on you, but Brian wants a 5/8” radius, not square corners. I won’t get into whether a 1 1/4” bit will cut as clean as a 5/8” bit, but I assumed the jig is square and wondered where you were coming from.
Well Halfmeg, that's why I gave him a source for 1 1/4" mortising bits and 1 3/8" guides, so he could use them with his template. I'm having difficulty understanding why you find this all so mysterious.

phill,
it's because you are actually mixing apples and oranges. you correctly steered me to what is desired - a bit and collar arrangement that satisfies the conditions for a square cornered template (stanley/bosch) to produce a 5/8" radius corner, then compromise it with an arrangement that would produce a 1/4" radius corner on a square cornered template, while stating it would make no difference.
i checked on the bosch online catalogue thoroughly and came up with zilch. had to email bosch for the part#. i do appreciate the lead. hope it bears fruit (not apples and oranges, though). i'll post their reply when i receive it.
thanx to all,
brian
Brian, you can get bits and collars all over the place. I don't know where you are located, but I'm sure that any woodworking store could order what you need if they don't have it in stock. I don't buy anything online but I look all the time. One source has what you need, and I am sure there are others. >>> http://www.coastaltool.com/cgi-bin/SoftCart.exe/a/accessories/door_acc.htm?E+coastest
(Pile Giles...bite me)
Qtrmeg ,
the items you referenced with the hyperlink appear to be bearings, not collars...
brian
Huh? I show mortising bits, mortising cutters and arbors, and collars (templates guides). Not a bearing bit in site. Try starting at their home page and look for door hanging accessories, there may be some freaky web dilemma happening here. >>> http://www.coastaltool.com
You should be happy with bit #45505 and collar #42048
Squawk if you have a problem, I will be goofing around here for a while.
not much of a picture to discern from, but what coastal shows as template guides seem too thick to be collars. i'll check into the part numbers you supplied.
hey, guy. thanks alot for carrying the ball this far for me.
brian
Your only problem will be what router base you are attaching the collar to, and if you have the locking ring.
You never said what you were using for a router...no matter, there isn't much going on around here except for whining about the new board, so someone is bound to get you fixed up before too long.
Ah, sorry if that was confusing - the large Bosch bit has a different construction (two pieces, an arbor and a replaceable cutter - these are sold separately BTW) and I was only trying to indicate that it works just as well as a straight bit which most people seem to be more comfortable with..

still looking for a source of over-sized collars...
#1 joseph - the templates are set up for use with collars. a bearing bit with a bearing the same diameter as the cutter will oversize the mortisse, since the collar deducts 1/8"... correct?
#2 i don't like the 5/8" radius hinges either, but they're common. they were obviously mortissed with a jig of some kind, and the stanley jig is the most common. just seeemed like there would have been a collar around for this particular installation.
#3 it now seems justifiable to do what i've found myself doing, which is to throw away the butt leaf for the door side and replace it with a 1/4" radius leaf and remount onto the 5/8" jamb leaf or replace the hinge butt entirely.
#the mortising planes sell for $70+ on ebay.

i went ahead and picked up the spring-loaded corner chisel recommended earlier for fun. a regular chisel has always served me well.
Jesasa (www.jesada.com) sells a 1 1/8, 1 1/4, and 1 1/2 top bearings that you can use with any 1/2 shaft dia bit.
They also sell a assembeled 1 1/4" mortising bit with 1 1/2" top bearing for use with Hinge-Mate.
I think that Eagle America has some similar products.
