The T track is simply screwed to the 1/2" slab of aluminum. The acorn nut provides tension through a 1/4" threaded rod and keeps the pull-handle gripped between the two sides and provides tension on the side plate which puts side pressure on the MSD strip in the T rail. More pressure makes the device slide slower and less makes it faster. > > The squeegee holder can pivot to either put the squeegee down on the bed or to hold it up off of it after a solder run and you want to move the squeegee holder back to the other original end of the board without smearing your deposited paste. > > The second photo shows where the squeegee holder would be positioned after a "solder-run" was made.

If it works as well as you hope it might be a product in itself. I've had boards made with surface mount components, but always populated by a board house with commercial equipment. I always figured the tiny surface mount components would be the end of hobbyist electronics. You've shown me that I lack imagination.
