Do not do as I do, for most the world evolves around chemicals. I have finished a lot of finishes without removing. I have finishes that were dissolved and rearranged without removing. Other times I have used razor blades, refinish an up-right grand without sanding, sanding creates work, I am a fan of scraping.
Again, do not do as I do. I dug a maple kitchen table out of a dumpster, no legs. I went into the fine establishment that threw the table away and ask them if they when were they going to throw the legs away. I paid them $5.00 for the legs.
Air plane propellers, I have one that goes back to about 1914, careful! do not remove labels, like pianos, some of the labels are no longer available.
