Title: Osage Drying Time
Post by: nlester on February 07, 2012, 03:45:27 pm
If you took a relatively green stave, and roughed it out to relative bow dimensions.  Under decent/low humidity, how long would it take before it was ready to work without being too wet?  I have some green staves cut back in the late fall and was wanting to get to them as soon as I could.

i have never worked green osage, but you will want to tie the bows down flat to stop them from twisting.

Reduce it down to floor tiller,then shellac the WHOLE stave,use shellac only...then give her a steam bath n make any neccessary corrections. Then start a hot box regimen out at 80 degrees and increasing the temp by 5 degrees every week...all the while monitoring the stave for checks n such each day. N in a month it'll be "dry" enough to tiller out. That's my short version,n much more needs to be explained.

I shoulda simply said go buy Dean Torges ' Hunting The Osage Bow

I read Dean's book.  I shellac the belly too?  I most definitely need a hot box.  Thanks for the info blackhawk.  I forgot about Dean's speed drying technique.

I built an osage static recurve, 60"t/t, 55#@26", with a stave that was 2 months off the stump. It felt dry, it worked like dry wood but after a few shots it began to take on set and fretted just below the handle. Now, this was a highly stressed design so that accounts for something.
  I prefer osage to be at least 2 to 3 years old and older would be better.

Yeah..I seal the belly too(the whole thing,back,side,n belly) when quick drying osage cus it'll want to check on the belly as well.

And go check out poorfolks.com on how to build a cheap hotbox


Should also mention this can be done and make a serviceable bow that harvests game,and the deer ain't gonna know the difference between a quick dried,or 30+ year old seasoned stave...BUT its my opinion and preference to wait and use "seasoned" wood with osage.

I most definitely would prefer a well seasoned stave....unfortunately, I don't have one.  Only green staves cut this fall.   I'll get it figured out.  Thanks for all the help everyone.

You can monitor the moisture loss with a cheap digital kitchen scale.  Once I get a stave to rough bow shape, I'll weigh it and write it on the belly of the bow.  Then I will check the weight every so often until it settles out.  You can really monitor which drying methods work best by doing this.  A piece of hickory loves being in a car on a sunny day.  Just be careful trying to quick dry a piece of osage.  It can me tempermental like everyone else mentioned earlier.

I can tell you this about the osage I cut last February. By March I had several roughed out staves,(near bow dimension),on the forms for a month,then up in the rafters of my haybarn over our hot and dry summer. I finished 3 or 4 of them in July with very little set. The wood has decent rings with with acceptable early wood,but not what I would call great by any means. But,with that said,I have built several bows since and they are very good performing bows.  I probably would not have attempted this with so little time to cure,(without the extreme drought of last year to speed things up),but,it obviously is well seasoned. I have always heard the saying that wood cures at the rate of 1"/year,so I figured 6 months should cure a roughed out stave. It did in this case,but who knows how it would come out in a wet year.  If you're willing to build a hot box,you can substantially shorten drying times. JMHO  God Bless
