Alrighty then... I have to say I have been suitably impressed with some of
the table extensions for contractor size table saws that incorporate a mount
for a router. There are some nice cast iron extensions like the Benchdog,
and if you do a simple image search via Yahoo or Google for table saw
extension you will find dozens of home shop built ones.
Now, my wife already gave me the go ahead to just buy the Benchdog, but I
could certainly make my own.
If you have used such a contraption what would you saw are their biggest
issues, other than not being a full on shaper. I considered having multiple
drop in plates, so I could pre-setup two or three routers for different jobs
or even different parts of the same job. Even if I bought a Benchdog or
similar unit I could easily make additional plates including close fit
plates on my bigger CNC mill. What else?
I saw the quick adjust setup BenchDog sells, but if you can lift the plate
out easily (which you can) its not that hard to depth set a decent router
before you set it in the extension table.
I was thinking maybe a tilted floor cabinet below for vacuuming chips that
fall below the table instead of being sucked up thru the fence.
