Normally, before mounting the wood block, the centers are marked on both ends of the block if it is a spindle piece, but because this is a very irregular piece, it is not necessary for this project.

Irregular wood blanks are sometimes moved around on the lathe to accentuate some characteristic that might be found in the wood, or there might be a hole that needs to be worked around.
