I will take some closeup pics when I get a chance
I used an old drafting machine from an old desk I no longer use for the x axis
beefed it up a little
the y axis is black pipe over drill rod with homemade oillite bronze bushings fitted and a nut over the end that can be adjusted to tighten the bearing as it wears
the z axis is rods from old printers with oillite bronze bushings fitted
a real hodgepodge of whatever I had laying around but it does work
some parts are cast aluminum from scraps, some are steel welded up, some are wood |
