Thank you Joe, for responding to my post.

I went on home page of router work shop, but what I found is not the one
what i had in mine, and not the one I saw Rick was using. The fixture I
saw him using had alum. comb, to which he clamped board and he was going
with it over the table using router of the router table, intead of
seperate router.

The fixture which is on the Oakpark homepage I made myself out of wood,
but it is hard to set up the distance between bit and fence.Maybe if I
would have it made out of hard plastic, not the wood, and predrilled
holes in the table and using bolts instead of clamps, it would be easier
to set it up.

Maybe there is somebody else who knows about the fixture I am talking
about.

Casey.
