I know it sounds like a pain in the ass but I can get some really nice and squared 6061 aluminum profiles to make the racks. And I'm planning to mount them on the turret of the Mazak and use a fly cutter on a shaft between centers to machine the racks in a serial way. That way I can make them in a easy way. I already have the jig to mount them so it's only a matter of program the job and start to cut. I need to make some holes and registers to mount the racks but still I think it's not that big deal. It's just that gluing the belt sounds cheap and/or not at all a secure option for me. But it's just the way I see it.
