I have a table saw with two stamped metal wings. I found a cast iron table from an old saw at a garage sale for $3. Cleaned up it should make a great wing.
Unfortunately it only has holes on three sides, and I need them on all four. (Since both it an my saw are craftsman, I am hoping the other holes line up, but better check before I do any new drilling...)
Any advice on drilling additional holes? I have an industrial drill and a big pile of drill bits I got when a tool shop went out of business, but it looks pretty thick. I know I have to keep oil on the surface, anything else?
