Morning all (and seasons greetings) , I am having to lay up some laminated panels for a piano repair. This is not something I am set up to do, I never work with large area of veneer and I don’t want to research and build a vacuum press for a one off job.
I built a semi “torsion box” lower platten with 3/4” MDF with ply webbing, and a beam with two cross pieces half lapped into it, you should be able to see the idea on the photos. The panel is about 40” long by 11” wide, it consists of a 5/8” MDF core which has already been edged with solid wood and two faces of cedar, currently about 3/16” thick. I will run both sides through the planer after glue up to take these faces down to about 1/8”.
Here’s the pics… one of the lower platten, and a couple of angles that hopefully show the clamp layout OK.
Will I get away with this..? Overall clamp spacing is 7”. .. other than longer/heavier sash style clamps I don’t have any more, I built the handscrew clamps especially for the purpose, so I’m hoping that I get the nod on this one :)
