: 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?

Try making something out of plywood or a laminate covered particle board.

You may be able to find some pipe which fits those holes. Otherwise, see if you an clamp a couple of pieces of 2x4 under the table and extend them to suppert the plywood.
