I'm looking at building a small mill/router with the intent of milling PCB's almost exclusively. I'll probably make some small plastic parts and whatnot as well, but as mentioned, it will be primarily for PCB's.
I have the electronics covered, so I'm just working on designing a machine. Pretty much I just need to find some affordable rails and bearings, but I'm not too sure what I require even.
I'm wanting 12" rails for both the X and Y axis (makes things easier for me, long story), and then 6" rails for the Z axis. I was originally looking at the linear rails/pillow blocks on Glacern, so those are an option. I also ran across THESE eariler, which look quite interesting. Also looking at Hiwin (or other) square rails, which would be nice as well.
So basically, what's the smallest rails that would be advisable to go with on a machine this size, and where are some places that have them readily available for a reasonable price? I'm a student, so money is somewhat tight
Thanks,
