Usually get our firewood in thirteen tonne loads of logs. Last time we got a load I cut a few larger bowl blanks out of the green wood, sealed the ends and all the blanks cracked.
This time decided to turn one green (dripping wet) to see how it might go. Have got away with this in the past with minor species timbers so thought it'd be an interesting project.
The timber is Tassie oak and the bowl dimensions after turning are 450mm dia x 110mm high.
The outside turned nicely, did not bother with sanding as it was too wet. Put in 4 grooves near the top edge and burnt em black with some wire hoping they would highlight the expected warping later on.
Inside of the bowl was going well until a "crack" noise was heard followed by the bowl suddenly turning not so true. Turned lathe off and sure enough there is a crack in the wood. Taped up the outside of the bowl to stop it flying apart completely and turned the rest of the inside shape.
Following pictures are taken one week later. I quite like the warping that has gone on so far however the crack has kind of ruined things.

The diameter of the bowl is still 450mm at the largest diameter however it now has a small diameter of 390mm.
The colour in the above pics looks a tad bland as the timber is drying out, picture below shows it with a slosh of water on the inside.

Put a few hours into this thing so am reluctant to just throw it out. Will wait till its dried out and in the meantime ponder a possible save. Weighed it today to monitor drying, 2776grams/5 pounds.
Cheers
