Subject : Laminating onto a veneered panel?
Posted : 2010-07-05 1:09 AM
Post #36094
I recently made some panel inserts for the sides of an entertainment unit using some shop cut highly figured oak veneers and a 1/4" MDF substrate. Had a strip left over that I would like to use for some drawer fronts but since it's only 3/8" thick I need to increase it to at least 11/16". Can I simply laminate another 1/4" MDF strip and 1/16" veneer?

The original panel was glued up with Unibond but I'm out of it now and really don't want to buy a half gallon for 2 square feet. Can I use PVA glue? If plastic resin is necessary I have a little Weldwood powder on hand. Will that work?

Jack,

Its not as important which glue you use as it is keeping your panel balanced. The ideal thing is to add the same to both sides of whatever you are gluing up to make it balanced. Obviously if you have a piece of oak at 3/8" thick you would have to cut it in half so you would have two pieces that you could glue to each side of your core. This would give you a balanced panel. On the other hand drawer fronts are not that large in general so you may get away with the imbalanced lay up you were thinking about. Bigger the panel, more the warpage when its imbalanced.

Things to consider.

Thanks, Darryl, that's the answer I was hoping to get. Maybe I wasn't clear on what I want to do. The existing panel is one layer of 1/4" MDF sandwiched between two 1/16" thick oak veneers. I plan to add another 1/4" layer of MDF to the existing panel, with a third 1/16" oak veneer on the outside. The finished panel will be oak-mdf-oak-mdf-oak.

By the way, I prefer Unibond for veneering, bent laminations, and glue ups requiring a long open time but I'm out of unibond and don't have any plans to need any in the near future so I'm hesitant to buy it just to toss the majority if I don't use it.

Jack,

Although the concept of a balanced panel is being accomplished in your description, well sort of, there is still another issue. Your panel will end up imbalanced because you are added more layers to only one side, not from the center out. Each time you add more layers to an existing panel it has to be balanced on both side. Because your additional laminations will be on just one side of the original panel all the pull, as the glue dries, will not be equal over the entire panel.

When you put it that way then yes, it is out of balance. Glued it up this afternoon so it's too late to do anything now. The drawer fronts will only be 15" wide and I can screw them to the drawer bodies in all four corners so I'll just have to hope they stay straight. This was the last of a batch of highly figured veneer that I used on the other furniture in the room so the only other option is to make new fronts with plain oak if I can't pull then in. Live and learn! Thanks for sharing your expertise.
