Uhm...If the rollers are at 45 degree angles to the tread, then the tread should be mounted parallel to the frame at the four corners; the nature of mecanum systems is such that you receive standard weight distro, speed, and forward traction, while gaining the manuverability of omniwheel systems.

Good luck.

I dont the the OP is talking about 45 deg rollers, and if OP did do that, he'd need the treads set up like traditional mecanum wheels (ie two treads / side) rather than the square shape he has now.

im just wondering how the work on this idea has been going along, because a couple of members on 1712 along with myself are working on a omni tread design as well. just wondering how far its gotten. and i think i figured a way to keep the treads in a straight line and have a good sprocket for them to move on.

Not so well, because I realized that the tracks would weigh a lot if they were made of aluminum and if each had a 3/16" steel link pin. Also (heh) I noticed that with my design it is physically impossible to install the last link, and therefore it is impossible to complete one entire track. To put the 1/8" steel pin in, it would mean that it would have to go through the 3/16" pin.
If I were to change my design, I would make the links out of plastic, and have cylindrical rollers instead of barrel shaped rollers.

This will give you an idea of what I mean. Sorry about the image, but without AutoCAD, Inventor, or Solidworks, I have to work with what I have: Microsoft Word. This shows the top view of my idea, and you can see the cylindrical rollers with a pin going through (maybe 1/8"). The tread links are joined at the top and bottom by another pin ( maybe 1/8").
