Heat treating Hackberry?

[eastcreekarchery]

What are peoples' suggestions about heat treating hackberry? I was thinking of going for a toasted color before tillering...

I'd get to at least floor tiller stage or even first low brace before heat treating then you could do it again later if needed.

I just did one yesterday. I  heated at 22"   28" draw was goal on this one.   Added  6# @22".    Light heat and a light tan coloring. took 30 mins per limb 68" ntn bow.  I couldn't see any change in the tiller other than weight.   Let it cool for several hours and finished it out without issue.

Your added weight might just be the wood being extra stiff before rehydrating.  Good to know that the tiller was fine and that back was ok without rehydrating.

I’ve gotten where I usually do it twice. Right after long string tiller out to 20-22” but before first low brace. Then I heat again when tillered out to about 25”. I do a long heat and the belly is quite dark brown but not black. You will gain weight both times. This probably leaves a belly that isn’t the most aesthetically pleasing but is thoroughly treated.

If done right, the weight gain is not dehydration. I do not go back to tillering for several days after ht and that is when I see the weight change. Definitely not a short lived or superficial gain.

In my opinion, heat treating hackberry is a must. It makes it a snappy shooter. I heat treat it once at brace height, and one more time at 26” on the tree. Nice golden brown. Then I’ll finish tillering the last 2” so there’s no visible color change. So far, it’s worked like a charm. My two favorite bows are hackberry.

How long do you heat one area for/how far away is your heat source? I appreciate the input everyone! Thanks!

I've done it with hackberry 4 or 5 times with very good results.  I always tillered first, then toasted it with a heat gun.  I'm agressive and do it pretty fast - takes about 30 minutes to do the entire bow.  I then re-tiller and often toast a second time.  If I toast a second time, another round of tillering is needed but it is a pretty easy job.
