I recently bought a used Craftsman 113 series 10” table saw. I don’t know how old it is. The model number is in one of the photos below.
The saw has four threaded holes in the cast iron top that go completely through (circles on the photo below). I found a user manual for a similar 113 series saw but there was no mention of those holes.
Any idea what the 4 holes are for? Feather boards? Clamps? What’s can I use them for and what should I not use them for?
BTW, this is my first post on the Woodworking site. Thanks!
