Tiller check please!
« on: March 20, 2011, 02:49:45 pm »
This stave is 62" NTN and Im shooting for around 60#@28"...right now Im at 50#@22" ....Ive been having some trouble keeping the limbs even...there is a dip in the stave so I placed it right in the handle...thought it would be a cool forward "Shrew style" type grip and it sorta put the limbs on different planes with each other, not to mention I put about 4" of reflex in it but the dip caused me to give the top limb a little more reflex than the bottom further complicating things. I think ive got it under controll sorta..but I could use some feedback from you guys....

Pics are a little hard to judge sometime, but is the limb to the left a little shorter than the other? Your tiller is close but here is trick for you to try..

put the bow on a tillering stick and lay it on the ground, trace the inside profile of the inner limbs while drawn and mark the sides of the tillering stick, then flip the bow over putting it exactly where it was  while reversed and look at the lines. it will tell you what needs to give where.
Does that make sence?

Wow thanks for the  feedback! Sailordad, thats a sweet trick, wish I would have waited to see that before I kept going. The limb on the left is the top limb, its 1 1/2" longer. I laid this one out Torges style, anyway I worked the bottom limb some more and a bit on the top limb. heres where its at now.

Im thinkin I should work the inner midlimb area closer to the handle on the top (left) limb. Any chance you could put that arc over this newest pic Sailordad?

not sure how accurate it is with differant length limbs
all my bows are symetrical

its easy to do if you have winwos paint
just open the paint program
click on "file" a drop down menu will open up
click on "open" then open the folder your pic is in
highlite and open the pic

then just use the elipticle option to overlay it

How much further do you have to go in draw length?  Looks to me like you ought to go back to your original limb configuration, make the right limb the top limb and then gently even the limbs up as you head towards you're draw length.  Be very careful making the bow bend right off the fades.  Very easy to get set.

Indianguy, that is a great trick, I will definitely try that.

 When I first started building bows I did the chalk outline on the floor for a while then years ago when windows first came out with "paint program" I started doing the oval  overlays. Since posting it on here I have seen some good and some bad with the use of it.  We should always keep in mind the overall shape and style of the bow. Not all bows should have an oval tiller. And bows with character dips and dives  or limbs with differing amounts of reflex must be carefully analyzed and not just matching the oval arch.  If you force a dip in the back to perfectly match the arch with will stress that part of the limb more then the rest of the wood around it. Also always be sure that the sides of an oval overlay are the same distance fron the tips or your oval will show more or less bend on one limb even if they are the same. Just the slightest tilt in the bow can cause an illusion as well. So be pro active and consider all factors.
 In the last pic the oval is shifted to the right and it makes the right limb look more bent then the left.

Nice, I really like it.  Good character bow.  Tiller looks good to me.  Keep at it, you're just about done.  Stop at least an inch or 2 short of your draw and let your finish sanding, clean up, and shooting bring it in.  Gonna be great.

Thanks gstoneberg! I got it back to 28"@52" and ran about 100 arrows though it after rounding the edges a bit. Its a sweet shooter! VERY little handshock and lots of early stringweight...Ill post some pics tomorrow of the handle and tips. Thanks to everyone for their advise today! Really helped :)
