I've also had problems getting t-track, but I've had no problems getting other extrusions. By joining a few together you can make a pretty good imitation of t-track.

On my table I've used two "U" shaped extrusions and a strip of flat aluminium about 25mm wide and 1mm depth. Place each U on its side facing each other, then slide in the strip and screw it down. This holds both the U shaped extrusions in place inside the groove. Then all you need to do is grind and polish the heads of the screws and find some suitably sized bolts to slide in the track (will need some grinding also).

Its more fiddly than t track because it is 3 pieces rather than 2, but once you've got it in place it works just as well.

Unfortunately after building a router table with these tracks, I was finally able to locate some of the real thing - so now I'm starting router table mk2.

You've all shown incredible ingenuity! One of thing I like about woodworking is the problem-solving aspect.

Reading of your exploits also reminds me that I'm very lucky. When I need a piece of T-track, I just walk ten blocks to the Rockler store on Lyndale Avenue!

I routed a shallow 4mm deep, but wide groove. Then a narrower and deeper groove on the same axis. Glued a strips of 4mm ply across the shallow groove. Passed an 8mm groove through the plywood and cleaned up and polished. Plywood T-grooves.

I had an idea not unlike : Tom, How about routing a groove as deep as necessary, and as wide as the guide. run a dado on each side of the track slot that is as deep as a 1/2 metal strip is which, and put that on each side of the dado and leave enough open as the slot in the track would be. Did any one follow, i am having trouble putting ideas into words

Default another source for t-slot router bits

Lee Valley also sell router bits to cut t-slots: sorry, it won't let me post a link because I don't have enough points, just go to Leevalley (dot) com and click through Woodworking into Router Bits and then into Rabbeting and Grooving bits ...

Look how many different ideas people have. That's great !!
Unfortunately for me, all the t and key slot cutting bits are out of the question because I just can't get them here.
I have found in the last week a place that sells a type of t track, either singular or double with a space between.
It's actually for hanging curtains. Pretty cheap too.
Have gotten no where with my jig though.
