This tree was cut down on May 17 this year. I rough turned it a week later (to about 1” thick) and sealed with anchor seal. By late July it was severely checked on the base with a huge crack through the tenon, but not quite all the way through to the inside. I turned it again (to about 1/2”) and re-sealed it, but could not completely get rid of the crack. During the second turning I noticed how dry the wood was and decided I would try the final turning today. That crack was less than 1/4” from the inside and those last few cuts on the bottom on the vacuum chuck were a little hairy, but it came out crack-free. Some kind of cherry finished with the Beall System. Of course the 8” buffing wheels I own could not quite reach the bottom, so I’ll be seeking out one of my woodturning buddies with more tools than me… that’s pretty much all of them.

Wish I could have taken more pictures. One guy took one look at that crack and said, “firewood.” I figured as long as it was not all the way through it was at least possible to finish it. I’m also interested to see if the wood continues to move, since it was cut down less than four months ago.

Great bowl and great save by turning away the crack. I know what you mean about the cracks. I have three roughed out pieces buried in my chip barrel and they have all cracked to some degree. If you can’t get them out, epoxy mixed with the sawdust from the piece will save most of them and gives them some character, too. I make enough firewood from cut offs so I save most things I turn.

Thanks for sharing. That is a very pleasing shape and right sized base for the bowl size…..........Jim

Very nice cherry bowl, the grain is beautiful. I have 6 cherry bowls setting turned green and latex painted and one small one waxed with bees wax to see how it would dry. Hoping they don’t crack. how do you dry yours?

Thanks Jim. I’ve heard of drying in the chip barrel with green shavings and I would like to try that sometime. Thanks for the advice on the epoxy. I think I’ll be trying that sometime soon.

Paplou: I dry mine by rough turning as soon as possible after the tree is cut to about 3/4” consistent thickness, anchor seal everything, and set in a paper bag loosely closed. This piece happened to be stored in my bedroom, but most of my rough turnings are in my garage. I never tried latex paint. The anchor seal product leaves the piece waxy even years later. For this one, I think my problem was I rough turned it too thick (1”).

Thanks, Pete!

Lou, rough rule of thumb for wet turn blanks is about 10% of the dia’, ie a 10” blank you would normally go to 1”, the important thing is to make sure the thickness is the same top to bottom
, if the bottom is say 1.5” then it will destress at a different rate to the thinner wall above and induce checks cracks. This is a gereral rule I was taught but does vairy with some species so I am not too sure about some of your home grown timbers. :)

Pete, that math makes perfect sense and I would go a little less. The original bowl was about 8 or 9 inches, so I should have rough turned it to about 3/4” back in May. I was also taught to get a consistent thickness from top to bottom.

I would love to visit NZ someday to sample that lumber. :)

Thanks for the advice.
