Has anyone had to make modifications to their table saw to mount a
Biesemeyer fence system (Commercial or Home Shop)? What's involved with the
process? How difficult was it and did fence accuracy suffer any?
I had to drill some 1/4" holes in the cast iron top of my DW746. It was
pretty easy if you follow the directions. They include a little jig for
setting the height of the mounting angle iron. All you do is clamp the
front rail to the top with a couple of pipe clamps and get it lined up with
the little jig, then drill the holes using the holes in the rail as a guide.
Works pretty well. You could go back and drill them out a 32nd bigger if
you really want the adjusability, but I found I didn't really need it. The
back rail is not critical since the fence doesn't ride on it. Mine is a
commercial with the long rails, BTW. An excellent upgrade, by the way.
On a scale of 1 to 10 with 10 being difficult I rate the job as a 0.5
after 15 years of use the bies (home shop in my case) the accuracy is
still dead on.....
All you have to do is drill a few holes in the cast iron tables of the
saw... IF I remember correctly (and it has been a long time) I just
used the rails as a template for the location of the holes.....
Simple job really...
Even without the template that comes with the Biese, it's an easy job to align
and drill the holes. A couple of measurements does it.

I put a commercial 50" on my Delta 12/14" 18 months ago.
It required drilling out a few holes and bolting it up.
(1) Buy the "best" metal bit you can find(no Walmart specials)
(2) Use a 1/2" drill with some guts.
(3) Have a friend over to work with clamping rail(s) in place.
(front rail is fairly heavy)
(4) Drill holes slightly oversize and "expand" opening to allow
for up/down adjustment.
(5) Take your time.
(6) Focus on keeping that drill and bit "dead level".
