Slimline made from branch wood from Australian Bottlebrush Tree in garden. Drilled & turned wet. Tubes inserted turned to slightly above required size left to dry 24hours.
Not too shabby. That's a dangerous game you're playing turning it wet. Even if it doesn't crack, you're still going to throw off the diameter so now you're nib, centerband and finial are all going to fit differently when dry.
If interested in preventing cracking, etc. of green blanks, check out the Boiling Wood instruction/tutorial from Steven Russell's site.
I use the method with my propane fired fryer and have yet to have a major problem with my 'Green" bowl blanks. Pen blanks are a cinch to do and one could boil several hundred in these cooker pots.
