Charlie, you've got most of the details right. 6mm all thread from the
base to the cross bar. Nuts and lockwashers lock the rod in place on
the base and on the cross bar. Cross bar is a scrap of oak. Tee nut on
the bottom of the cross bar midway between the all thread supports.
Chunk of 3/8-16 all thread with a knob on one end and brass acorn nut
on the other.
The picture was taken shortly after I first made it. Later I shortened
the rods up a bit. I just stuck it together quickly and didin't measure
anything because I needed to use it. It probably took me less than
fifteen minutes to make.
Bob, I hope that's enough detail for you.
As to the edge guide, I'll do a drawing and post it on Monday.
Charlie, that plate on the router is a Bench Dog plate. Levelling
screws are in the table on Bench Dog tables. Those big clear plates are
nice when hand holding the router, too.
