To the BowClamp boys.
My new BowClamps worked as claimed. I didn't have to park my truck on the worktable glue up after all.
The extra clamps you see weren't really necessary but they were close and I figured the edges wouldn't mind the extra help.
Thank you to Cecil Arnold for advising me to sand the mating surfaces of the MDF before applying glue.
Thank You to Glenn Bradley for the idea of using a pastry roller. Worked like a champ. However, I found that a left over mud smoother from the sheet rock walls helped in smoothing the glue out enough to where the rollers were much more effective.
Charlie Plesums statement: If you lay two sheets of MDF together without glue, it is twice as strong and stiff as one sheet. If you glue the two sheets of MDF (or anything) together, so they become one sheet that is twice as thick, it is eight times as strong and stiff as one sheet.
Convinced me to do the glue up.
Thank everyone else for their contribution. This was totally a piece of cake using your information. I can't remember why I dreaded it so.
