in this video i am turning an old sewing machine base into a table by adding a solid oak table top. link to my tapering jig video: • Making a tapering jig
I don’t recall what size the drill bit was…I closely matched the holes already in the frame. The idea wasn’t to make the holes larger in diameter but elongate them side to side. As for the screws, I reused the original screws. Hope that helps.
Edit: sorry I thought this question was on another video. I used the screws the client provided, which I think were the original screws from the sewing machine.
