I've been through a few refurbs for teammates over summer and have a few thoughts and questions on finishing a bat.
Edges
Simple jobs is just a sand and some steel wool to finish. Then a buff on the polisher.
If real bad, I use a hobby plane to tidy up the edges after the front and back of the blade are sanded. Then finish as above.
Blade and back
I have a detail sander to go from 80,120,240 depending on the job. This gives me the dreaded twirl lines unfortunately. That only seen to show after a light oil. Then I hand sand at 360, 400 and occasionally a light sand in 800 with the grains. I have recently realised that steel wool can actually replace the lighter grades and is great at removing the twirls. Here are a couple of pics of a ugly Indian monster I just finished. Still needs a final polish.

Questions
Does anyone else have experience with using steel wool and a finishing sand.?Seems very versatile.
Does a random orbital sander definitely not leave twirl marks?
