Tonight I lost patience and braced it. What a bear! 65#@22". Now its time to tiller this thing out back to 65@26, shoot it in some, then get some chrono numbers and pull it on back to 28 again. I sure hope it holds! Tillering these is an exercise in flinching.

After unbrace, the profile was exactly what it was when i first made it before it took any set. I took half the deflex out when I sinewed it. It had 1.5 inches deflex after sinew, it has 3 now, which is what I built it with. So, the sinew did help. Because before sinew the bow had taken an inch of set.  That's gone now.

Seeing it lay perfectly on ots original lines makes me think I got the tiller perfect. Pics will tell tomorrow.my tiller tree ( litterally a tree i loop the string on a branch and pull the bow down ) doeant allow a far away look see.

I shot it tonight. Id like to report ots super fast, but I dont think it seems any faster than before. I hope to chrono it next week. And shave some tip mass down as well.

Looks really cool! Highly deflexed shorties are a really neat way to get a long draw out of short wood.

Looking at your force draw curve, I can see exactly where your recurves are doing there thing.  That last entry tells an ugly story however.  At 27" stack is showing by jumping 9 lbs.  Your entry at 28" would suggest that the belly is now thoroughly crushed.  It should have been an even more drastic jump in weight.  I'd almost be willing to bet that you're readings throughout the force draw curve will be significantly less than the first time you charted it.  The last inch must of been a smidge too much.   Josh

You may be right gundoc, i dont know. My set up isnt the most reliable. I notice i could gane maybe 3 pounds of draw an inch then the next inch i would gain 6 then 3 again. I think perhaps an average of every two inches of draw should be looked at instead of every inch.

Also, that draw chart was made after my pics were taken and every inch i measured, i drew back down before going to the next inch. That way i knew the wood was being worked.

Wow, that's a scary bend at the handle, or maybe it's the angle.
