My father's been using UHMW in tape form on his Biesemeyer faces for years. I actually used that on my Biesemeyer to replace the trashed center pad that the fence glides over the table with. If you really like the slipperiness of UHMW, there's always UHMW tape. They also use many fasteners, as UHMW will get wavy where clamped (corian is too rigid to do this). The good UHMW fences I've seen screw to the plastic from the back-side, but they were built around aluminum extrusions and bolted construction.
UHMW doesn't glue, and I don't want exposed screw heads (even countersunk) on the fence face, or ANYTHING that can catch. I've seen many fences done with UHMW, but I'm not sure how you'd attach it to a steel Biesemeyer. That's held up very well for a few years now. I've since switched to using Clear Gorilla Glue (NOT Super Glue). The plastic expands and contracts at a different rate than the steel, and in the winter it popped off on one end making a sort of scary tuning fork. My first attempt at attaching corian was with epoxy. At that point, you should be able to clean off the glue and contact cement on more formica, but in my case, the plywood was already beyond repair (I bought the saw cheap and well abused). You can lift the formica with a heat gun and a scraper/chisel. Underneath the laminate you'll find that the plywood has been attached to the steel frame by using countersunk self tapping screws.
Just FYI: Here's what my switch looks like (notice the missing red cover on stop): Of course they don't sell the red plastic button separately, just the whole freakin cover (A24898), but you can't even find that anywhere. Generally not a big deal as the button itself is still there, but I'd like to have the big red plastic cover just to make it easy to pop off with my knee or whatever. The only parts I need are the table insert (which seems to be 'sort of' available, albeit it's expensive) and the big red STOP button cover is missing. The tough thing here is that it doesn't seem that anyone has any parts for the thing. The extension table also has some peeling laminate. On the fence the lamination peeled off, but I think I can either stick that back on or perhaps buy some formica or something and put a new one on. Top is very rusted, but that'll clean up nice. Part number on the saw cabinet says 36-L500 Type 2. So I just picked one of these up (5HP version) at auction.
