Limb pad angles
« on: March 09, 2009, 11:29:00 AM »
I was wondering how anyone who builds take down bows, measures and cuts limb pad angles.
Also, what angle do most of you use for recurve or longbow?
I know the takedown longbow from Bingham's uses 11 degree angle.
I'm trying to figure out what tool I should use to be as accurate as possible.

I have only made T/D's using Bingham's design as you noted, but I made this jig to use on the table saw.  Once the riser is cut to length, a taper jig like this ensures each angle is cut the same.

Cutting on right side with that jig is way to dangerous. Its better to cut that piece on left side of blade. Since you have slide chanels in table you could make jig for that left slide.
I would not cut like this but maybe it fits you... but i soo a couple of hard injuries caused from simlar jigs wich run on normal right side glide.
Will you eat that? If not, why did you kill it?

Hmm...how to describe this in english.
1st- Piece is not fixed, if hes not holding it, can easy slide to back side of blade and will be projectiled directly in head,torso...
2nd- That triangular piece can be pulled first in the blade and when its pulled in hole , saw bends wich will make less space for handle piece wich man is working on. That will result in compresion of it and will be thrown or diagonaled wich can lead to ugly cut on left arm, i asume man is holding it with it. Right one is on jig.
3nd- Since his jig is on right side man stands directly behind blade.
And im sure that there is more

Why better or left side:
1st - Your body and head are not aligned with saw
2nd - If triangulate piece is pulled inn the hole betwen saw and table you are away and you have more control over working piece, since you hold it with right hand you will push it left away from blade and not in it.
3rd - You dont need to cut all the way true the handle and you can easy remove triangular piece when 2-3mm still holding on end. You can free one hand for that, easy. On right side that is not possible sice left arm is holding working piece and right one is holding jig.
4th - You cant cut yourself so easy as on right side
5th - All maschines have jigs for diagonal cuts on left side.
   

Important! There is protection missing behid saw.
Sorry for my bad english. I hope it can be understood.
Will you eat that? If not, why did you kill it?

Thats a pretty slick set-up, however I don't have a table saw. I do have a compound miter saw. I might see if that will work somehow.

Anyone else?

I thought about using my compound miter saw for the limb pad and decided it might be a bit dangerous.  I thought I might make an angled block to clamp to the table and then bump the riser against it to hold it.  I also have some toggle clamps that would allow me to keep my hands away.  I may give it more thought.

I did make a sled using toggle clamps to hold the piece firmly and am now re-considering changing it to the left side of the blade.  Even though the clamps are doing the holding the right side cut "feels" a bit dicey.

I like to use the sliding compound miter saw myself.  I use Bingham's design, so what I do is just cut parallel to the line, or as close as I can get it, and then just clean it up on the jointer.

About the table saw thing - I too was taught to always cut on the right side of the saw using the fence.  My first lesson was this,

"You're sole purpose for being alive while using this saw is to keep the wood against the fence"
