Title: Tiller Check
Post by: Jefe on March 30, 2020, 09:22:38 pm

Hey everyone,

First time poster here and I am looking for feedback on what will hopefully be my first successful solo build. 

The piece is 63" ttt and 1.5" wide with some dry checking and prop twist.  Hoping for some feedback on tiller at this point (long string) and any advice moving forward.  Thanks

Looks like the outer third is going to be a little stiff but is looking good overall! What is the tips tapered to?

It looks to me like your bending nice through handle. Your right limb looks like most of it’s bend is about 5” to the left of the seam in your concrete wall. I’d put a “x” there and stay away from it till it evens out more. Left limb looks stiffer but mostly bending in same area. . Your outers look very thick yet. There is much less stress as you move out limbs towards tips. Your tiller needs to reflect it. The further out the narrower and or thinner it needs to be to allow it to bend.

When I look at my tiller, I look for straight areas. If it’s still straight and not bending. It needs wood removed.

Have you ever seen Eric’s “tillering gizmo “?  It’s helped out a lot of people

Looks like midlimb on needs work. Jawge

Stay away from the inner 1/3 of the bow for now. That area is affected more by leverage early on and can be overworked easily. Once you get the limbs bending evenly and together start bringing the bend back towards the handle. On a bendy handle bow I like to feel the handle area bend slightly as I reach full draw.

Thanks guys!  This helps a lot. I had a gizmo at one time after taking a class with pine hollow, I will see if I can find it.

Seeing the front profile would help.  Unless the tips are very narrow, they look pretty chunky in terms of thickness.  I would probably reduce the size of the overlays too at some point.  That looks like  a sweet stave!

Tips are a bit over 1/2” and for sure chunky. Overlays are as well. I was scared to take too much off before getting second opinions. This thing has a lot of checking and with me being green I thought I’d take it painfully slow.

Slimmed the tips and overlays down then rasped our limbs and cleaned up.

Please wait for the experts to chime in, but here is my suggstion:

There is a kink at the black circle. To get rid of it scrape the green marked area a little.
The outer thirds of the limbs are to stiff (red area) give that a good scrape.

Tips look better!  I think the suggestions so far are good.  Do you have a tillering gizmo?  If not, a straightedge (eight inches or so, or even a 12" combination square or ruler) can serve the same purpose.  Run whichever of those you are using along the belly and look for even spacing to show what is bending and how much.  Mark spots with less space between the straightedge and belly, and take off wood there.  Stay away from the center for now, and don't get carried away with the tips - the last few inches shouldn't bend as much as the rest of the limb.  Hope that makes sense.
