Its been a while (some years!) since I posted in the forum, but thought that my latest attempt to create an accurate adjustable drill press fence might be of interest. The picture really shows how it was built - I needed a 500mm length of '1MOD' gear track (which I cut in half to give 2 x 250mm), 2 x 1MOD gears, a 500mm length of 8mm stainless rod and a set of pillow bearings for them. Because it was via Amazon I ended up ordering more rod and pillow bearings than I actually needed but I'll eventually find a use for them. the total cost was £54.

I used my router table and fence to route 10mm wide channels in the fence (7mm deep)and the MDF baseboard (4mm deep). The gear track was drilled and screwed into the fence grooves and rides in the waxed MDF grooves. Once that was completed I just determined the packer height needed for the pillow bearings so that the gears had minimal slack. I can actually move the fence back and forth just by moving the gears, but for comfort I 3D printed a handle and fitted that to the end of the shaft.
Once in the required position the fence is locked into position by the turnlock that can be seen in the front right of the image (this was part of an earlier design, that had one of these at each end but as I tightened them the fence would move slightly - that doesn't happen now).
Now that its built I can see that if I'd bought 2 x 500 gear tracks (extra £18) I could have extended the MDF board to go either side of the pillar and put the pillow bearings and shaft behind the pillar. That would have allowed the fence to go back as far as possible, but in my experience of using the drill press, the fence has not needed to be that far back.
For info here's the item descriptions that I ordered:
