I have been looking all over for prices on linear rails and screws/backlash nuts. I find literally hundreds of websites but not a single one with bloody prices! I imagine they are quite reasonable since you can get a 40in rail with two slides for $40 on ebay...
Im looking for 2x12in rails & 2 slides on each, 2x18in rails & 2 slides on each, 2x6in rails & 1 slides on each, 1x19in screw (1/2in 10-20tpi), 1x13in screw (1/2in 10-20tpi), 1x7in screw (1/2in 10-20tpi). Such measurements would yield a 8x11in working area but without prices its just a thought, with a full gantry I can remove 16+in of rails and reduce the table size for even more cost savings.
The ideas from HERE guy must have used about $400 in aluminum from the looks of it.
I would consider using pillow slides and such if they where alot cheeper.
Also does anyone know a good website for buying bearings? Im making a high speed spindle with changeable tool posts and would like to compare bearing types and prices. I know high speed ceramic bearings can get upto $30 each but their should be hundreds of alternative types <$5
Well, Thanks ahead of time!
Oh and where does everyone get that crazy square c-channel aluminum framing stuff from??? Im in Vancouver and have never been able to find it... It would be useful for many projects in general...
