Title: Tillering "graph"
Post by: pronghorn23 on February 15, 2009, 10:28:00 AM

I see photos of bows in tillering trees and behind it is a large graph of squares on the wall to check the tillering.

I was wondering what material people use to make these graphs...laminate? plywood? etc.

I'm in the process of building my workshop and would like to put one up behind the bench.

I use the joints of my cinder block wall as a reference.  It is only a reference so the material used doesn't matter.

I've seen them made out of cardboard, massonary board and etc.....I've made a temporary one out of cardboard but it got tore up.

I'm fixing to make make one to put behind a new tillering tree I'm building.  I'm going to print it on a big plotter printer so I don't have to mess with drawing or painting it since I've designed mine on the computer.  Then I'll laminate it on a piece of 1/4 massonary board.  I'm going to make it nice since I finally got off my butt and got shop looking nice now.

I'll post some pics when I get it done.

You can use anything, know of someone that use's peg board,which also works good.Remember just because the tpis are even at full draw don't mean they were even getting there.This is where most hand shock comes from.

I just drew mine on the wall w, a permanent magic marker-- broken up into 2'squares.  You could just get a piece of that peg board-- connect the holes ("dots") w/ a marker and you'll be good to go. Ive found it helpful number the lines across the top with corresponding numbers on each side of the bow, and to make every other line red, instead of black-- makes it easier to orientate in comparing the bend in the two limbs. I use fixed pulley and bow clamp /rest, as opposed to a tiller tree. Good luck - the peg board is an easy way to go-- The little lady probaly have liked the board thing better than the direct wall application thing that I opted for.-- Than again she also probably would have liked be parking the Motorcycle in the garage for the winter, rather than the living room. Shes really been a peach about it--but I know its going to cost me something sometime. LOL

I agree Roy.  I'm working on a BBIH Tri-lam right now and one of my limbs is still an 1" to 1 1/2" from being even, based on pictures and computer graphing... BUT I'm loving the way it's shooting.   :)

I had a piece of framica counter top left over from my kitchen and it works great. The whole back has lines all over it.

I second the pegboard! 1"squares and can be used as a tool board if needed.

Pegboard is the way to go. You can draw on it and erase it very easily if need be.

What ever you use is great.But like PAT said it's just a reference.This just helps to see the flat spots.

I use a cardboard grid made for sewing, I think it was less then ten bucks at JoAnns when I bought it.
