Thanks for the pics. I don't think it would distort (see my first answer). But I would add a 1cm margin, that would help to cut the laminated back with some tolerances.

I would not make the form the exact size but just a little larger as I would be afraid that the press will roll the eadges over the form. I worked in a vener factroy for 10 years and the way we made panels was first with a sheat of 1\28th venear then the core piece then the finish piece the two outside pieces going in one direction and the core going in the other .good luck Bill.''''''''''''''''''''

<p>Thanks Pierre. The secondary back is ment to seperate the guitar from the players body. The design was one of many different attempts to boost the volume of the 19th century Early Romantic Guitar. It's a full second back which is attached to the guitar via brass screws and a system of wooden risers.</p>

<p>I've attached a couple phots. One of the original instrument owned by the illustrious guitar historian Matanya Ophee, photo supplied with his plans of the guitar and the other borrowed frm Gary Southwells website of a beautiful replication of the same instrument. I hope neither of these fellows mind as the photos are being borrowed for educational purposes.</p>

<p>In both photos, it's a little hard to see but, the finished attached back is visible.</p>

<p>I could make this back the traditional way of veneering but I'm learning to laminate with vacuum pressing and some of the finer details elude me at this point. The form I've made will go inside a vacuum bag with the pieces to be laminated situated on the top. As the bag empties of air it should close around the form and seal tight against it on all sides. My question concerns any overhang of the laminate I might have, Will the pressure press on that overhang and distort the laminate? Or does the laminate need to be trimmed flush with the sides of the form before going into the vacumm bag? </p>

For what I know of vacuum clamping, it shouldn't : if the vacuum sheet presses both faces of the overhanging veener sheet, pressure will be equal on both faces, so no dsitortion should occur. But I'm not sure if I fully understood what this top is meant to be?
