I think the Padauk I got wasn't completely dried, so when I placed the billet in the dry room the end checked.

Is this a lost cause, or can I simply CA the crack shut as soon as I resaw it?

I don't have enough space to cut it off, because I also want to get ukelele sides out of it.

Even when dry it has a tendencies to check. When i used it I had enough to just cut them out. I think CA would work the way you want it to. By the way it is very hard to bend. It can crack easily. Soaking in hot water helps and so does slow easy bending....Mike

The stuff is pretty brittle & will easily split. Be careful with the ends. After thicknessing I put masking tape along the ends.

I've only bent one set & it was very easy to bend although I know many have had trouble. The set I had was perfectly quartered which may have made the difference.

You can ca it after you resaw it to keep it from cracking futher. It will like to crack as drying when thick, so you might want to resaw i as soon as possible to keep the cracking to a minimum. It does like to crack. I just bent a set for a dread without any problems but it was from a dry well quartersawn billet to start with. The problem i'm worried about is the red dust impregnateing the light colored binding i want to put on it. gaah

I took it out of the dry room and as soon as its exposed to the higher RH outside the check started closing

It looks closed, but it probably won't stay closed. The cracks are still present. Ergo, heed Mark Groza's advice. You'll be glad you did.

I also want to mention that sometimes there can be difficulty gluing up. Titebond works well but glue up within about an hour of jointing the edges, Waiting longer can cause problems. I think it is an oil issue or oxidation? Not really sure. Now the stuff I used was African Padauk. There is also an Asian Padauk and I don't know if they have the same issues....Mike

I would skip the ukulele sets and just build with good solid wood. Enough problems come along that you don't need to start with a problem that you know you have. I doubt that the wood is that expensive. It's one of the least expensive back and side woods at LMI.

+1 for resawing soon.

I can't do that, this is a part of the OLF challenge, ordering from LMI would disqualify me.

I believe the wood is Burmese Padauk.

Also the resawn set did not exhibit checking, and there are enough wood for me to cut off the checked portion if necessary.
