A buddy of mine is getting into speaker building. His boxes are veneered MDF. We were discussing veneering (which I haven't done) and he said that he was using the method described below, which he found on an online forum.
What are the wreck's thoughts on this method?
------------ As a cabinetmaker for many years (more than I like to admit), I can tell you firsthand that every cabinet shop I've ever seen used contact cement. The main difference is that we spray it on.
I have also done the yellow glue/ iron method for years on some projects and can also vouch for it's effectiveness and ease.
Here's a step by step I wrote up after answering the first hundred questions about the procedure.
As an alternative to contact cement, try ironing on with yellow glue.
- Prep substrate (should be perfectly flat and clean).
- Cut veneer 1/2"-1" oversize.
- With a foam roller cover, apply coat of yellow glue mixed with a little water (to let it roll on easier) to the substrate (I usually just pour a little glue on the suface and roll it around)
- Roll on a coat to back of veneer using push-pins or tape to hold it down flat. Make sure no glue gets on face of veneer!
- Substrate may need second coat, especially edges. You want the material to be built up on the surface.
- Let dry.
- Position veneer on substrate (it will not adhere without heat).
- Using household iron set at high, proceed to iron on the veneer, starting at center and working out. Keep the iron moving slowly so as not to burn the veneer. (trial piece good idea to get the feel for it). Use edge of wood block to keep pressure on it as you iron.
- Trim as usual.
- Before glueing adjacent sides, apply masking tape to the edge of the veneered side where it meets the raw face that will be getting glue next. Again, make sure no glue gets on the face of any of the veneer!!! (this applies to using contact cement also)
A couple of big advantages are: Bond strength. Ability to position veneer. Surface will be FLAT when you're done. Contact cement is much more difficult to control, and really isn't recommended for unbacked veneer.
