I turned some green spalted maple and left it a little oversized and put anchorseal on it everywhere except the tenon on the bottom so I wouldn't interfer with putting it back on the lathe in 6 mts. Should I go back and put it on the bottom too? If so, how can I get it off when the time comes to put it back on the lathe? The chuck is a 3 jaw type with straight edges and it's difficult to tighten too much because the wood is weak.
