Gluing up the second cabinet did not go as well. My jig is giving up. One of the extra panels i glued on to account for the extra 3/4" on each side tried to call it quits on me. I clamped the sucker back into position to try to get this one last use out of it.
Sadly i couldn't tighten the clamps any tighter and the second cabinet didn't sinch down as nicely as the first. Ironically, i think the problem was with the water.... it was really warm this afternoon and the water i spread on the MDF panels dried before it soaked in at all. By the time i spread the glue and lined everything up to be clamped, the water dried out and i was bending practically dry MDF. Such a bummer.
This approach would be great and i will definitely try it again with a couple of modifications
- the clamping jig should extent PAST the end of the braces you're clamping against to make sure you get pressure all the way up to the edge AND past it. Pretty sure this would have helped my edges that didn't lay exactly flat. My after-thought panels didn't cut it
- i think more than 3 braces on my clamping jigs would be helpful. when i tried to apply clamps where there were no braces, the MDF of the jig started to bend and split. need more places to apply pressure with clamps
- the MDF should be good and wet. it really does help the bend. and regardless of what you've heard, it does not instantly destroy the MDF. If you soak it in a tub of water or something - then you will have problems. I might consider another material in the future. i was looking at the HDF 1/8" at Home Depot today. I couldn't get much clarity from my masonite question thread
, but i think i might try that stuff some time. I'm still pretty anti-plywood, although the thin Luan (is that what it's called?) that i saw at HD didn't look too bad.
