Louie S. and I built a Pro-Tools Bead Roller. This is a nice kit, all parts are USA, no Chink shit. If any Commies are offended by that statement, kiss my red, white, and blue ass. The pics will tell the story. We welded in the tension adjuster. We next clamped the 2x3 tubing to a piece of plate. The spacers either got lost or not sent, so we used the gears; I smeared some tip dip on there to prevent weld spatter. Worked just fine.
