Welcome to the Quilting Board!
I made tables up out of old bathroom cabinets - we put the cabinets on 2 X 4s and then put locking wheels on the the 2X4s, then braced the top with 2X4s for a couple old metal parts out of an obsolete telephone system cabinet - plywood or doors would work. It was nice to be able to move the cabinets around as needed. I also had it hinged so one end would raise if I wanted to use gravity to help feed things through the machine. I could also use the table on wheels to roll the material through the machine. Oh and I could put stuff in the cabinets and drawers. I was making historical type tents and awnings. The biggest awning was 24 X 100 those tables did it all.
NEVER let a sewing machine know you are in a hurry.

Well, DH found the paperwork after a week...survey SAYS...
Mercury M-280L Compound needle feed walking-foot sewing machine
"Can be adjusted to sew from light to heavy fabrics and leather. Presser feet are interchangeable with standard Singer type 111w feet and attachments."
Says speed is adjustable, too. Cool. I haven't touched it yet, but I guess this answers a lot of the questions. I'll let you know how it works out if I get to actually use it
Exploded parts chart is REALLY ugly
