Dan, my apologies for hijacking your fixture. Have used this fixture for about two years. Replaced the bottom rails once and sanded them smooth to eliminate tracking roller groove a couple of times. Always use masking tape. ALWAYS tighten side to prevent slippage. Only use the end stop when board length gets close to 19" max fixture length. If the 8" plaques are all cut from the same board - I set the board into both ends of the fixture to set the base fixture width to match board width. Then I set the top of the board slightly less than 1/8" proud into the fixture, using a handmade gauge - setting the board at both ends to tighten the rails. Move the board to the center - approx - and squeeze the board into the fixture.
The wingnuts at the bottom of the fixture prevent the bottom from squeezing in. Only the wing nut in the rails is used to tighten the piece into the fixture. Approximately one turn tightens the board.
Therefore every board that goes into the CW gets measured by the CW.

Having fun with my CW now!
