Does anyone here have a set of these? http://www.ptreeusa.com/panel_glue_up.htm
My wife gifted me two sets when they were on a 40% off sale. I haven't used them yet but have mounted them to a 2x attached too a wall and together they'll give about 7' of clamping length. They claim to work from thin to up to 5" thick. When I first saw them I immediately thought of a benchtop to break them in. <g> I'd planned on adding a Bessey K-type between each of these clamps, plus one or two on each end.
I'm planning on a thick (4"+/-) top, 36" wide.
Also, I'm looking at using epoxy for the glue-up, since these clamps are designed for gluing up all 24 pieces ay once and I'll be working alone. I'm looking at West Systems epoxy http://www.westsystem.com/ss/hardener-selection-guide/ . With their 209 extra-slow hardner I'd get a 3-4 hour thin-film working time and 20-24 hours to cure to solid. Since I'm in no rush, lucky to get a day a week in my shop, in the clamp and up against the wall seems like a good place to "store" it for a week or so. I *was* thinking that I should probably line the clamps with waxed paper to keep any squeeze-out from making the clamps permanently attached. <g>
I'd sure appreciate any feedback or thoughts you may have on this!
