Fixed Gantry small precision begineer project advice

[Boyan Silyavski]

HI Yasu,

My advice:

-use 800w water cooled spindle, it won't waste too much electricity and is powerful enough for serious aluminum jobs. Even steel with miniature bits.

-if i am to machine the parts, as we spoke in PM , better design it so that the rails are say 2mm deep in a channel which is wider 2mm than rail. So when i machine all parts, you will not even need a square, cause you could align the rails to the edge of channel. Just check how deep they must be so nothing interferes / the carriage/ and have in mind the edge is beveled so check that out too, for the depth i mean.
Also when you draw the holes have in mind how rails are cut / both end equal spacing to first hole/

By the way i have somewhere here 2 aluminum mounts for the 800w spindle.


Thats what im refering to:
