It has a 19" diameter steering wheel to crank down on which drives a 2 inch diameter acme thread press screw! The whole thing weighs in at maybe 300# and has thermostat controlled heating if desired. The surface area is just over 21X25 inch. Free to me, just helped a friend for the morning loading up equipment! It was made to laminate art work, which needs a lot of pressure and heat. But it laminate wood with ease, and nice to add heat when I wish! The C press framing you see is over half inch thick steel.
