My wood cutter gave me this what I think is prime white ash stave. Been a learning curve as the ash does don’t heat the same as Osage. I know ash is stronger in tension but I don’t know how much. The bow is 2-1/8 at the fades on the belly. I trapped hopping to balance the tension and compression. The back at fades is a hair over 1-5/8.just guessing on the trap. Going for 69”ntn. Pyramid. Mid limb on belly1-5/8. Back mid limb hair under 1-1/4. Interesting the trap back ended up about the same as my Osage backs. It’s off the heat bench and caul. Here it is at this point.

Ash should be a prime wood for heat treating. Like George I've never been able to make an ash bow without fretting but I never heat treated ash. I think I would heat treat to a dark chocolate brown. Also, your fades are too steep. The fades are the transition between the rigid handle and the working limb so the bending limb should come at least to if not into the end of the fade.
-
Pat not sure what you are saying.
-
I guess I was looking at your riser block before you blended it into the limb. ::)
-
Which one do you like best?
-
I like the shape of the one on the right but I like the slope/length of the one on the left. But the left hand one seems to have a rather abrupt change at about the glue line. I'm leaning toward longer gentler fades as most of my set seems to come in the first 4-6" of the limb.
-
Osage tip overlays.
-
Where are you guys seeing a riser block and glueline?
-
Pat, I saw the different color and assumed it was an added riser. I am not all that familiar with ash.
Preshaping the overlays before gluing them on makes them easier to blend into the limb tip. At least the taper back towards the limb.
-
It’s a selfbow guys. If it fails on the belly I may put gemsbok on the belly and retlller.
-
Tip overlays complete.

Me too. It's our age, ya'know :D

Thats a neat idea on the tiller board...profile already there for reference. I may have to trace out my purchased Osage bow on my board....P

Looks great. Thanks for sharing this build

In my profession, they say the mark of a master teacher is that he recognizes what ideas are worth stealing. Is the same true of bowyers? ha ha

Not sure I understand but if I was worried about theft I probably would not put it on the world wide Webb. More of a joke. Arvin

Ash is one of the most inconsistent woods I know of. So many species where the wood looks about the same. Some ash is very dense and makes great bows other ashes not so much.

Whistling Badger, 99% of us freely share.
Arvin, she's looking good.

I'm looking forward to seeing how it turns out. I'm working on a white ash selfbow currently as well. I'll second the comment about inconsistency. The other stave from this log had nice thick rings and made a pretty nice bow. This one has super thin rings with lots of early wood and is more than twice as thick but bending quite a bit already. One limb is thicker than the other but bends more. Not too sure this one will turn out nice, but yours looks like it might!

I was joking, too. We all share and borrow ideas. :)

Is this about the right color on heat treat? Infrared says about 300degrees.
-
Darker, chocolate brown.
-
Ok
-
How about this 375-400
-
Heat treated to around 400 degrees. By the way at what temp does wood egnite. Arvin
-
I had my doubts about the white wood . After heat treat and a few short bends on the long string. I may get surprised. Time will tell. Keep tuned in.😀😀😀
-
Lightly sanded looks pretty good.

Looks Great!

Got her shooting. 1coat of finish.

43@26. Will shoot a flight arrow tomorrow and see what she has no frets . Took two inches set . Seems fast.

Well done! Jawge

Well it shot 450gr broadhead 180yds into a 5-7 mile wind and 205 with wind to my back . Pulled 27” so it should be close to 10 gr per pound. Not bad . Arvin

great bow arvin and very interesting to watch "king of osage" make a bow out of our most common bow wood we have around here.
glad to see good old ash rehabilitated ;D
you can't heat treat enough - it's getting better every session ;D
and yes: ash varies a lot from piece to piece, but usually when thick ringed and not too much early wood it's good stuff.
-
Thanks guys it’s been a fun build. Arvin
-
Awesome bow Arvin! Now I need to step up my ash bow standards after seeing yours. Like others have said ash is a roll of the dice wood as far as quality. The fastest one I’ve made to date has huge rings. Pulls in the 50s and is about 65” long and the limbs are only 2 rings till the handle. Good early to late wood ratio though.
-
It looks great Arvin. Anyone think it might have taken less set if he waited a couple of days, after the heat treat, before bending it? Just asking... congrats and thanks for the build a long. :OK
-
Bob: That does not play a role imho. But on the pics it looks like it was heat treated in flat position. If heat treated slightly reflexed the final profile would be dead straight, imho ;)
-
thanks. I have always waited after heating wood thinking it needed to to equalize before working it. When I use to work more white wood, I even kept it in a hot box between tillering sessions due to our (Arkansas) high humidity. I do always heat in some reflex too... just like Gary Davis taught us many years ago at MoJam. :OK
-
Looks like you had a good piece of Ash. No pun intended.Around here they die standing.Elm isn't real healthy either, but we have tons of healthy white Oak ,and red Oak, some Hickory, Patches of A Horn beam,Walnut, Birch, etc. Nice job on that one Arvin.
-
I cut my teeth on ash but never heat treated back then. I found osage and pretty much left my ash standing in the corner for years. Recently made a few ash bows pyramid style with a heavy heat treat and was pleasantly surprised at the performance. Now wishing I would have cut more before they all died.
Your ash bow looks great.

Thanks for the build along Arvin, great stuff and beautiful bow
