Topic tags/keywords: sycamore bowl lathe turning

My neighbor had a sycamore cut down and I took some of the wood. I used a chain saw to cut some bowl blanks. I turned the outside of the bowl and the bottom leaving a recess in the bottom. I glues a piece of 3/4 plywood into the recess into the bottom to screw into my faceplate to turn the inside. I let it set for about 5 days before I could get to mount it into the lathe and turn the inside. when I was ready it had cracked and is now firewood. My question would be do I need to turn the inside and outside all in one day for? Some of the other bowl blank pieces I had cut also cracked. Should I leave the tree in a trunk state? Cut it up with a chain saw and turn it complete all in a short amount of time.

Most turners I know will turn the bowl inside and out leaving the wall thickness approx. an inch thick then wrap it in a couple sheets of newspaper and place in a brown paperbag for a few months to allow the blank to slowly dry, occasionly checking it, then turning it to size. Or you could use the Microwave drying method on your blank then turn it. I just recently turned a few bowls out of Sycamore, turns easy enough but am not impressed with color or grain. But then again free wood is always nice to have….......Good Luck

Some wood is prone to cracking for myriad reasons. A friend was turning some beautiful mimosa and it cracked about 1/4” the next day. Other woods will hold up if you toss it across the shop (uh, I’ve never done that). Keep on making shavings!

Sycamore cracks badly and quickly. Get it rough turned or end coated immediately. Waiting is bad with sycamore.

Once it’s dried, though, it’s fairly stable.
