So after selling the lathe ( had it 8 years, wasn't all that interested in turning ) I decided to fill that open spot by building a stand for the miter saw.
It had to be mobile, have fold down wings and I wanted a way to extend the wings out further for long pieces. I did some internet research and incorporated the adjustable fence I saw someone do to account for adding a zero clearance insert and the swing out arm to support the wing.
For the extended wing support, I made "slides" using 1/16" wall steel square tubing - 1-1/4" for the outer, 1" for the inner. The nylon pan head screws take up the slop between the tubes & makes it slide nice.
