Hackberry advice needed
« on: July 15, 2011, 12:40:27 am »
I have made a few bows over the years, but never from whitewood. Today I took delivery of a nice hackberry stave. It is 64in long, 3in wide, and plenty deep,  straight, with a little prop twist. Rings are pretty wide, and it is clear with no knots.

I am sure open to suggestions as to design before I start in with the drawknife.

Thanks,
Bob

28" draw? I would leave it full lenght, 1 3/4 wide to mid limb, them straight taper to 1/2' tips. Hackberry moves very easily with mild heating. Get it straightened out and flip the tips some. You will be happy with it. Hackberry makes a fast bow due to its light physical weight.

Pearl gives good advice. Keep all the length you can. I've made several Hackberry bows bwtween 64"-68" and have been pleased with them. On the other hand I have tried several short bows as well and not had much luck. I don't believe Hackberry to be real good in tension.

I made what I consider a short bow with Hackberry. Its 60" ntn, 53# @ 28" draw and has a working handle. I toasted the heck out of the belly and it has shot thousands of arrows so far with zero change in tiller, no chrysals, no splinters and no loss of draw weight. Toasting the belly is a good idea and its cheap insurance. I also burnished the back ALOT with a Mason jar and I believe it to help strengthen the back??? Who knows,? I have been called crazy a few times!

I have had great results with hackberrry in tension. There was this 60# longbow I made, aroud 78" or so, I screwed it up tiller wise and tryed to break it by using it as a one of those olympic vaulting sticks, or maybe a pogo stick is a better way to describe it, and jumping on it off my steps and it would not break for anything. It would just bounce me right back up. lol Short hackberrys do seems to be bit more trouble to pull off than longer bows though of course.

Thanks all, I got off my lazy uh-oh and did a "hackberry" search and answered most of my questions. Laid it out this am. Should go bout 1.75 wide and taper from mid limb with a little more limb thickness than I would on Osage. Looking for right at 64in OAL with about .50 tips.

Just now came in from the shop. Have it all roughed out on the big Grizzley, started to do some heat on the prop twist and my heatgun either threw a rod or floated a valve. Guess I'm gonna have to crank up the steam tube. Man it's hot in SW Arkansas!!!!
Thanks again,

Bob your layout sounds like it will be real good.

@ Pearl,
 I guess length is relative to who is making the bow. 60" is the longest bow I would personally make with a working handle so that doesn't sound very short to me :) That is what I should have clarified.

@ TMK,
Really?

Stuff I want to hear also.  I have a nice stave I want to start also.  Except I would like to get a 30" draw from it.  It is 79" long but it tapers from 1 3/4" wide to 2 3/4" wide.

I have had nothing but good luck with hackberry.  It responds best to sharp tools and will sand to a beautiful finish if you want to take the time. 

1 3/4 is plenty wide for it, be sure to add a few extra inches of insurance for the overall length if you use the "double your draw length plus 10%" calculation for a stiff handled bow.  All I have done is American Flatbow designs with this wood, but have wanted to try the pyramid bow design on one of the next hackberry's I get my hands on just to see if I can eke out a little more arrow speed.
