I'm topping an office desk with Vyco (an Alvin product which has few competitors e.g. Borco). The material is a 1/16th inch thick, very tough, and flexible. They advertise that scissors work; but in my practice that results in a very uneven cut. It's also insanely expensive.
Will a flush-trim bit on a router work? I have visions of too much heat blobbing the cut into a melted mess.
I can report that both a flush-trim bit and a 3/8" quarter-round work extremly well. It does appear as tho the vinyl melts; but it also appears that only the removed portions are hot enough. The effluent does tend to stick to itself and glom itself into a sort of fuzzy mess; but it brushes off easily. There was no noticible smell from the heated vinyl (the plywood substrate gave off a nasty formaldehyde oder).
All edges were securely fastened down with 1" 3M double-sided polyester tape; and all the bits used were very sharp high-end bits.
Very pleased with the result and recommend a router to anyone.
