HELP!!!
I have seen people turn green logs in to natural edge bowls.
I doe not remember how to prep the log, and most of the other details.
I have a section of freshly downed (from a storm) ash about 12" in diameter and about 20" long.

Lots of places to look. I just turn to final thickness of maybe 1/4-3/8 and wait for it to dry before final sand and finishing.

A while to load, but loaded with pictures. Not an endorsement of some of the techniques shown! I'd at least trim off the outside "ears" for safety, as well as counterbore for the spur center, If I used it. Keeps you from kissing a flying bowl.

Monte,

You prep it the same way, the only difference is where you put the foot.

Cut it like this;

See "Log Cut"


But, if this tree just came down it most likely will not keep the bark if you turn it.

A tree must be dorment, so a tree cut down in the winter has a better chance of keeping the bark. In the summer the sap is flowing and bark is more likely to come off when it dries.

Sorry. :(

The bark will stay on fine if you reinforce it with some thin superglue. As you cut, run it along the cambium/phloem and it'll stay fine. You may need to repeat a couple times as you thin things out. It's not the sap, but what eats the only living part of the trunk (cambium) that you worry about. Bacteria and critters that dine there are much more active in summer. Cut soon, no worries.
