Title: Question for the group
Post by: TimothyR on April 03, 2020, 07:54:45 pm
Is this black locust?  And do you have to take sapwood off or can a layer be left on?

I'm pretty sure that's BL. I haven't used any for 15  years but I remember the popular consensus was that you could leave up to to 1/3 of the limb thickness sapwood for a natural backing.

I made a bl bow that was almost all sapwood in the limbs, because the tree was too small to do otherwise. It was a great bow and finally failed in compression when over-drawn.

Looks like BL to me. The bigger tree in the 2nd pic looks like it has quite a twist to it.

I agree with Pat on both counts.

Pat. That pic was just added  for bark reference. I cut a larger one down in the same area. and peeled the bark off. I just wanted to make sure that it was bl as I thought it was. The one I cut is pretty straight, 10' long and 5" at the base. I think I can get a couple bows out of it. Didn't know if I should take the sapwood off or not.

Yes BL will grow in colonies.Where there is one others usually are there too.

I agree that is black locust.

I recently made a bow out of black locust that ended up almost all sapwood.  There is just a small amount  of heart wood on the belly.  It turned out to look really nice and has decent performance.  I am currently working on another in which I am chasing a sap wood ring so I end up with more heart wood so the contrast is sap and heart wood is more even.  I am hopeful this one will be even better.

Good luck with your black locust.

Yep, I would say that is BL.  Small thorns, right?  I can't zoom in enough to tell.  My experience with BL leads me to take the sapwood off.  It has checked on me really badly when just"peeled and sealed".  I have a couple of staves now that I didn't have time to work down to heartwood, so I left the bark on.  The sapwood is a real bugger to get off once it is dried.  I think if the sapwood is thick and you like the contrast, I would chase down to the last ring or two before the heartwood.

Do you see the long seed pods?
I've made many BL bows and learned on it.
If you do not have enough heartwood then you can lead the sapwood.

I have tried the sap wood method with agonizing results.  The backs would either break, or the bellies fretted. Probably me , not the wood. I made 4 with no luck with that wood. Then I found a thicker ringed log ,and chased a clean ring into the heart wood. All of those came out good with no breaks, or frets, so I favor chasing a heart wood ring with Black Locust . Same thing with Osage. JMO. Good luck with yours.

Here is the one I cut. Should be able to get 1 or 2 bows out of it. Hopefully

Timothy, just because the tree is straight doesn't mean it's not twisted. Have you split it yet?

Looks like enough heartwood there for a bow? If yes, don't leave a sapwood back. Jawge

George has done as many if not more locust bows as anyone here on PA. I'd listen to his suggestions.   :OK

I split the log today. Got a set of billets and 2 bow staves. One will have to be a bendy handle though. I'll post pics tomorrow. thanks all!
