I can’t cut straight!!!!!!

blownonfuel | Posted in Construction Techniques on June 29, 2009 09:04am

I need some help cutting mitered soffit corners. I’m putting up my soffits and cut a couple at 45 deg. and my cuts are not that straight. My mitered corners look like a fault line. What do you guys use to get straight cuts? I am using my worm drive to make my cuts. I need some tips.

Thanks

    I cant cut very well overhead with my worm drive either!!!

      I like that one Bobby.

        That was a bad joke. Sometimes i will cut the first one at a 45, Cut the other one long , put it up and mark it then cut, So you can put the first one up and just fiddle with the 2d one.. I can cut straight with a worm drive but if i use a little saw my cut looks like a roller coaster unless a tack a straight board to run the saw against

    Are these exterior plywood soffits?
    Is it a jagged cut with the correct angle or is the angle off and the cut jagged?
    Is this a new worm drive or old

    1. blownonfuel | Jun 29, 2009 09:47pm | #6

      Yes, p.w. bead board soffit. Angle is good just not straight on the edge. Not too old of a w.d.

    I always carry a block plane while doing soffit work.

    It works like a champ on 3/8 fir ply

    it's a soffit, not furniture or trim.  quit using miters and and butt the pieces. 

    1. blownonfuel | Jun 29, 2009 09:49pm | #8

      I can't John. I'm using beadboard and it won't look right at the corners.

        tone down the saw...

        use a straight edge...

        look at the lonf axis of the cut and quit making short cut corrections...

        cover the cut with trim...

         

        cover the cut...

        it will look just fine...

        It ain't fine homebuilding, but you can fill the gaps with caulk.

  5. mencheman | Jun 29, 2009 09:47pm | #7

    anyhow the saw if old has excess run out causing a wobble blade rotation.
    what makes cutting these 45 unique , if you snap a chalk line does it still produce a jagged cut

    How about clamping a framing square or level on the soffit. Give it the offset you need so your saw base can ride up against it.

    lay one piece over the other...

    cut the 45 on both pieces at the same time....

    I trust yur cutting these on the deck and not overhead...

      Thanks Guys. I think I have enough tips to get it right now.

  8. stevent1 | Jun 29, 2009 10:18pm | #15

    Make a shooting board for your saw. 1/4" mdf and a rip of plywood. Leave the 1/4" "wide". Glue and srew throught the 1/4" into the ply. Run the left side of the saw foot to trim the sled. Then trim the small side with the right side of the foot.  This pic shows trimming a door blank.

    Put either edge on your line and you will get a good cut.

    Make your cuts upside down and the cuts will be splinter free.

      Thanks. I like that.

        See what happens when you use a worm drive?

        Siewinders are easyer to keep straight cuts on trim.  Now the easiest way I know is to cut the pieces at 48degrees.  It always seem to work out better.  Use a block plane to get it right!

        1. blownonfuel | Jun 29, 2009 10:44pm | #19

          Won't the block plane tear out the edges of the plywood?

          1. frammer52 | Jun 29, 2009 10:59pm | #20

            Not if it is sharp and set to take out small quanities.  Practise on small piece!  Then go to the store and by a sidewinder!

            By the way, with soffit plywood, I always but with a little caulk in between.

            Thanks.

            I really doubt buying a different saw will make your cuts any better. I do trim work with a worm drive.

          4. bobbys | Jun 30, 2009 01:06am | #23

            Me too but only cause i have a 500 dollar miter saw that my boy takes and never brings back!!!!

          5. doodabug | Jun 30, 2009 01:18am | #24

            I have 2 sons. the only way to fix that is give it to him and buy yourself another.

            What is a dad for anyway?

    2. bobbys | Jun 29, 2009 10:22pm | #17

      One can always draw a line and run a razor knife over the line if you Have to cut on the good side, That will stop splinters to!
