Question
Forum Responses
From the original questioner: Thanks. We'll try some 6 mil plastic and let you know. From contributor R: I have done this before by lightly contacting the veneer to a sheet of MDF. Then you can carefully peel them off. From contributor B: 3M makes a product called repositionable 75. Kind of like the glue on sticky notes. I've used it on other projects, but never on the router. From contributor T: Why use a V tool? I would think a small diameter spiral would work. Perhaps the smallest downcut you can get. Also... you could try the thinnest spoilboard you could dare use. Would improve hold down. From contributor A: Use an 1/8" ø downward spiral cutter to cut the veneer. The 3M spray adhesive will hold the material down with no problems. From contributor G: Do not use 6 mil plastic! It will wrap around the bit after some of it is loose. Try sign-makers masking paper, low tack. It will not have this problem! Having said that, using the 3m low tack spray glue (Office Depot will have in the art supply section) will probably work fine for holding the small pieces. From contributor P: We [Benz, Inc.] make an aggregate tool which we refer to as a vertical trimming unit, but it is more commonly known as a floating head. It looks very much like a hand router and fits into the motor spindle on your machine. The cutting tool is set to be exposed from the bottom of the unit to the depth of cut you are looking for. The bottom of the unit has a non-marking material (Teflon) which travels across the material you are cutting. It is designed to trace the surface and move up and down to accommodate any tolerance in the surface of the work piece you are machining. In your case, the floating shoe would act as a hold-down device keeping the veneer flat against the spoil board. Depending on how much of this kind of cutting you do, this may be a good solution.
