No -- have you ever refinished 1000 or more sq ft of oak sanding with either an orbital or drum sander? Simple question
Your question was answered in the OP's first post though, had you read it: "The problem is I've never done such a thing, and neither has anyone else I know."yes I have installed many thousand sqft hardwood floors and also finished them (including drum sanding). but I'm also not the OP. Thanks for asking.
I did read the OP's post. My question was to you. Evidently you have never refinished 50 year old floors.
