The Evolution of the Tillering Gizmo, Lets Make One

[mississippidave]

Eric, I tillered Maggie's new hickory bow with the Gizmo you gave me at the Jerry Pierce Memorial Shoot this weekend.  I really enjoyed talking with you and the tool works great!  Cheers, Dave

now this is one great tool. I have a couple tillering jobs set aside that will be back on the stick when I make one of these babies.

[FurFlyin]

Thanks for the post.  That will be very useful.

Simple but VERY useful.

Do you have any video of you doing this process that you care to share?

Mr. K, just wanted to tell you this was the first tool I made when I started earlier this year, and will be in my arsenal FOREVER. It's the number one reason I get any kind of good tiller. Thanks again for donating it to us.

[Eric Krewson]

No videos at the present Eric but I have thought of making one to show how well the gizmo works. I would have to do it with my digital camera because I don't have  a video camera

Eric,
Have you used the tool on R/D bows?  They are often flattish in the outer limbs...

[Eric Krewson]

Never used one on a R/D bow.

I have used it on r/d bows. And it is a pain in the butt to tiller a r/d bow.. But it helps a little.

[glenbo]

I made one last week and used it for the first time,I am quite impressed at the results and ease of use.Great idea Eric

This gizmo is what I use exclusively, well besides my eye, to tiller my r/d bows. From my first one in january and even now with my 6th on the bench. I made mine about 3" long tho, and when I get to the limb tips, I usually only use the gizmo to go until my deflex begins. After that I have found there is no reason (and dangerous) to reduce your limb tips too much.

Is this for use only on the selfbows? Will it work for glass bows, recurve and long?

[Eric Krewson]

Never heard of anyone using one on a glass bow. I suspect they are only useful on a selfbow.

[Jesse Peltan]

To answer your question blue tick, the tool works as a gauge to measure and mark the limb, helping you obtain a tiller where the limb bends according to the arc of a circle.  If the bow's full draw is supposed to have the limbs bent according to the arc of a circle, then this tool works for that bow.  Basically it's for bows that have straight working limbs, or limbs that are curved according to a circular arc.

will this tool work on a pyramid bow?

[Eric Krewson]

It will work just fine on a pyramid bow.

[Red Tailed Hawk]

Eric i have to say that this tool works wonders, such a simple tool can be so useful.

Eric, what diameter are your pegs on the tillering tree? I used one that is 1/4" oak and it broke it off when I pulled to 18"!
