Tillering tools

[beachbowhunter]

I will need to be doing my first tillering in a week or so and need to get my kit set up and could use some advice.

What to you recommend for a tillering string? I only have some older strings that probably not long enough.

Also, I'd like to see some examples of tillering trees, etc. I need to build one.

Thanks!

I have a 14 strand full-twist B-50 tillering string with a loop on one end and a timber hitch on the other.  It is 72" long.  No tellin' how many bows that thing has been a part of.

Here's my tillering "tree".

Here's a buildalong I did a while back:

Great, thanks! I am doing a glass laminated bow if that makes any difference..

I will also be watching this as I am interested as well.

With glass laminated bows, if the stack and tapers are just so the tillering is sorta built in.
With wood bows wood is removed and the bow exercised,to teach it to bend.
With glass bows once,strung you,measure at each fade to see how they compare. Usually I want the bottom limb a little,stronger by about 1/8 inch. This can be,adjusted by sanding the edges of the limbs and also the face of the glass.
Most often it will,come out close.

I helped out on one I made with a friend last year and we had to do exactly that.

John, I like your tillering tree but I dont have a big wall to put one on permanently. I want to build one that I can measure draw weight out to 30 inches or so. But it needs to be portable.

I use old strings. Jawge

I just have a hanging scale and an arrow marked with draw lengths.  I can pull the bow down and get the weight but can't get a good look at the shape.  Sometimes I take a pic at full draw if I suspect an issue.  As stated above, I build glass bows and they are generally within 1/8" if I laid it up right and the bends are right if I profiled the limbs the same.
