Hello to the forum!
I recently caught the CNC bug and have been spending WAY too much time on the zone . My last project was building an Al melting furnace, but I have yet to put it to any good use ...
I have been considering building a metal, belt-driven table, but the prices for extruded aluminum and pulleys are prohibitively ridiculous ... enter plan 2.
Build a cheap, small CNC. Use it to cut out some XL pulley patterns. Cast the pattern. The only snafu is I don't have any machining capabilities (lathe or mill). I am, however, casting in petrobod ...
Has anyone cast their own pulleys or large aluminum "extrusions" (c-channel)?
Will the finish be good enough not to tear up the belts?
Thanks for any input!
