If you haven't yet commited to the inletted tracks in the bench top, you might want to consider the under bench mounted receiver system.
Providing you have not yet finished your bench top, the mounting bolts and holes can be filled and covered with formica or whatever your using for a top, which leaves a completely smooth bench top.
The under bench receiver system allows for using many tools, quickly changing tools, or haveing no tools at all set up, again all the while having no holes, grooves, slots, rails etc. breaking up the surface of the bench.
Considering I am having problems getting images posted, those who have desired to see the set up, send me their snail mail address and I send along a CD and cover letter, showing/explaining the system and what I recommend.
Keep em coming!
