I am the last person I would ever have expected to be building a mechanical press like this. I have been a strong proponent and user of vacuum bags of all sizes and shapes for 25 years. However since I’ve become interested in marquetry and in traditional methods and materials, things have changed.
This press incorporated a capacity to apply “hot pressure” by heating 1/2” thick aluminium cauls (20” x 20”) in the large bed or smaller 10” x 20” x 1/4” aluminium cauls in the two smaller beds. I first read about heated cauls in Pierre Ramond’s book “Marquetry” where he describes their traditional value for flattening and stabilizing veneers and veneer packets. They are also very handy for re-activating and re-gluing veneer surfaces that have for one reason or another (read some mistake of mine) failed to stick properly the first time. It works very well and I use the caul heaters far more than I ever thought I would. (OK the BBQ’s.)
The whole press framework is made of D Fir from the building supply, fairly dry but by no means “dry”. The only fastenings are in the bottom rail and the short cross beams and they could come out now. All other fastening is 192 gm hide glue. The non-metal platens are MDF and the blocking is D Fir 4” x4”. The screws are from Lee Valley.
Photos 1 and 2 show the press in action.
Photo 3 shows one of the platens being heated, also the other parts can be seen disassembled.
Photos 4 and 5 show the joinery
Photo 6 shows the last dance for my fine old kettle gule pot. I got my genuine Hold-Heet pot yesterday.
