Finished up a small bowl this weekend and documented it through the process.
Started out with a section of spalted maple that was near too soft to turn.
Knocked off the corners a bit on the band saw before chucking it up on the lathe and started working to smooth out the bottom a bit.
After getting the bottom flat, could start to work on the sides.
Made a tenon...

and after some clean up to resolve some tear out, turned it around and chucked in the 4 jaw to begin work on hollowing it out

Lathered on some sanding sealer quite thick and let it cure for a bit... ended up with a fair amount of free mulch
Used a parting tool to cut out a channel for an inlay...
Filled with crushed abalone shells and CA glue.
Did another one as well, but wont bore with the step by step... just the before and after. I still need to do another layer of shell in this one, so it's not completely done.
Before...

and after...


Need to work on some knives as I'm behind, but wanted to get this wood used before it got too far gone. I have two smaller bowls left from this maple and I'm done with it. This same tree ended up giving me some really nice wood. Here is a couple bowls that came from the same tree I did later last year.

Again, not as good as a 'real' coring tool, but may be worthwhile.
