A while back I inherited my grandpa's old Delta table saw and jointer, powered by a couple of good old Maytag washer motors. I'm guessing that the Delta table saw is 1960's vintage. It doesn't have any table extensions like my dad's saw has (also an old Delta with cast-iron extensions.) There are 3 threaded holes in the sides of the top. Does anyone have any recommendations or leads on where I can get some extensions?

Thanks,
Dean
