Problems with lacquer finish.

Larry I have had good luck redoing the dividers on 2 machines-use a heat gun to soften the glue were the vinyl wraps around the cardboard to remove it. Scrape off glue-if the liner itself is warped clean it and spray it lightly with water, clamp between two pieces of wood that have blotting paper two side glued to boards. Let dry over night and they have almost always come out perfect. Use rubber cement to re-wrap vinyl. On the metal faced ones-same process except I sand and run through my vise to flatten and spray clear before I re-wrap.

Not vinyl though, Abe. It's leatherette (cloth reinforced embossed paper).

Thanks for the tips on the record dividers I could use some ideas there. I did wonder about damping them and clamping but most things I have attempted that with have ended up warping again when removed.. Maybe these are a different material that will stay better after clamping? How did you access them? Does the whole liner set come out if you remove the two upper an lower screws?

Larry you are right about the material it is a fabric mix but so is vinyl. If you use wood glue it is water based and will make the fabric as it wets it more flexible. I have wrapped sticks with wax paper and used clamps to hold the material in place in some bad cases-but the results are very good. If the panel re-warps than it was not made wet enough. I restore art for a living and work on paper a lot-you need to experiment a bit. I have a machine called a dry mounting press-a large clamp iron that puts down a lot of pressure and heat. Try this dampen the board put it between 2 pieces of wood and use a bumper jack and your car to add a LOT of pressure and do it in the sun. This will flatten out the panel. I have NEVER had that not work.

Or, just spray it with 3M Super 77 contact adhesive. They'll be stuck down until the second coming (or first, depending on how you look at it).
