Not much of a woodworker (I’m a measure 3 times, cut with chainsaw kind of guy) but I decided to try and build a drill press table using T-Track for the fence to slide in. I had no tools to do this with, so after some research, I decided to buy a router bit rather than go thru the expense of a dado set. I finally got the router bit (Freud 04-140) and some T-Track. Using a scrap piece of 3/4" plywood, I routed in the channel. The router bit is a straight 3/4" Bit and the drawings for the T-Track measure 3/4" on the outside. As you can see in the photos, the t-track will not fit in the channel, not even when using a hammer and a block of wood so as not to damage the t-track.

I just measured the OD of the t-track and the width of the channel in the wood.

T-track 0.770 - inches
Channel in plywood 0.700
As most of you know, 3/4" is 0.750

I’m disappointed with the results and have no clue as how to proceed. Any suggestions?

While posting this, I thought maybe trimming off a few thousands with the table saw would probably work, but since I went thru the trouble of taking photos and posting this I’d go ahead and post it anyway.

Just reposition the straight edge or jig to widen the groove.
