Hi all,
While working a universal tablesaw jig (that Joe - Bladeburner shared with us a couple weeks back) I found that one of my greatest challenges was drilling and countersinking the additional holes required to fasten the t-track to the base. I found these 82 degree countersink bits for #4, #6 and #8 screws on the Lee Valley site:

I just centered the track with chucked bit, put a drop of oil where the hole would be drilled, slowed the DP down to about 540RPM and cut away. These bits drilled the pilot and countersink easily through the aluminum track. (They are just HSS but seemed to cut well through all ~32 holes ok.)
Just thought that I would pass this along, as I found it hard finding the type of bit that would work for me.
