Hey guys this is my 49 inch osage sinew backed bow I have got at 26 inches right now. I am too scared to pull it back another inch. Please tell me what you think about the tiller.

Wow! That's pretty cool! How many lbs. is it pulling? I'm not expert on tillering yet, but it looks pretty good to me. Unless you'd want it to bend more at the midlimbs.

Im not sure the poundage I dont have a scale at my house that will work, I will found at asap and post it but im guessing by the feel between 40-50 pounds. I may try to make it bend more at midlimbs and go for 28 inches.

No expert here myself

All the bending is at the fades, I wouldn't trust shooting it.

roy now is the time for your great talent of show the rest of us what you see. Wheres your box of crayons.

that left limb looks almost flat. I would try to get it bending more. you can add some heat to the belly to get the weight up. I dont know what the max draw should be though.

That tiller is pretty bad...I'm not gonna lie. Need much work.

It's almost hinging out the fades on both limbs.

All that sinew and wood midlimb out is just dead weight.

I'd retiller for a more even bend past the fades.

That osage is some incredibly strong stuff.....wow

Needs more bend midlimb.

I put more bend midlimb and it is way too light now :( bends to 28 and probly more but its far too light its just a kids bow now and kept way to much deflex, I should not have removed wood mid limb in my opinion.

What you are referring to as deflex is probably set taken in the inner limbs since that is the only part of the bow that was bending. The farther you pull a bow the more set(deflex) it will take. If you would've pulled it to 28" with the tiller it has in the pictures above it probably would've taken even more set than it did, Just My Opinion. You could put it in a reflex form and heat treat the belly and you would gain around 10 pounds or so.

I think keeping it the way it was would have hurt you or somebody one day. A safe underweight bow is always better than a lit stick of dynomite, IMHO.

everyone is pretty right. its not a conventional design. you have a lot of mass and thickness at the tips in your pictures. better to have a 20# all day shooter than a broken nose...

lets see some updated pics....

I've watched as you have progressed through this and enjoyed your experience vicariously. Building bows is fun. Experimenting is fun.

That was a very, and I mean VERY aggressive design in the first place. I never would have tried it. If you learned anything in the process it was worth it. If a kid gets a bow, that's just gravy.

Roy from Pa · « **Reply #17 on:** February 13, 2011, 10:51:00 PM »

You should start another bow, had you shot that bow like it was, sooner or later one of the limbs was going to break off, prolly at full draw, that could hurt. Look at it as a learning experience, we all have lost bows here.

Your tiller is not that far off I would agree with the rest of the guys that it needs to bend more midlimb but the tiller is not terrible

What glue did you use for your sinew ? If I had to guess I would say tightbond, your sinew job is not the best I would buy some hide glue and take your time when sinewing making sure you lay the sinew straight down the bow, when you apply sinew properly this design is very safe to a 28 inch draw

Its hinging really hard at the end of the fades on both limbs. It has to be worked from mid section to the tips. I would back up a couple of inches and work on it until it starts bending even. right now its very near being a broken bow.
God bless and good luck, steve
