the push block is the best way I think, it can be just a simple 12" x 12' block of wood with a handle or a peg for a handle ,most coping selds are a waste of money, I have many and have tried many out..
Fence ,,that's the neat thing about the router table it can be anywhere on the table and if you try to line it up with a track it can be a real PITA job.
I use a swing fence most of the time , that I got from the OP system setup.
Bob and Rick are the Pro's and you can pickup many,many tips from them called the Kiss way of doing things
Just a note about the plate ,it can be anywhere and anyway you want it to be, it just holds the router for you so to speak..
The top,I would suggest you keep it low to the floor , about 28" to 32" high...you can use your weight to keep the stock down to the table unlike if it's to high.
Well Bob, I've been reading up a little here in the meanwhile and think I'm starting to understand better. Looks like it would be a real pain to line the fence up with it anyway, so maybe a coping sled or even just a push block is the way to go.
If you use a push block (or coping sled) up against the fence, doesn't the cutter contact and cut the edge of it as well as the workpiece?
