Scratch the ACME. Today I snagged a homebuilt XY table to cannibalize for parts. http://boise.craigslist.org/art/4894831991.html Across the gantry it has a 0.37-ish rolled ballscrew with a nut threaded on one end, with a max OD of .247" I have the saddle channel plowed out to nearly that, can easily go the extra few thou to have it just clearing. Will run a big ballnose down the center if it needs to be lower down. Of course that screw will need shortened a bunch. I plan to give it as much cross slide travel as I can. The other axis is a "vintage" Star ballscrew linear actuator made in 1997, inside a 2x2" aluminum extrusion with a block on one side. I'll mount that to the side of the bed with the block down (keep the chips out of the open side) and make a dead simple bracket to mount from the side of the block to the original apron mounting holes on the saddle. And it has motors, bleeping expensive Superior Electric Slo-Syn 200 step steppers. A NEMA 34 connected to the Star actuator direct drive with a Lovejoy and a NEMA 23 with a belt drive to the other axis. The builder for some reason put the large pulley on the motor. The table is HEAVY, made of nicely put together wood. It shall become the new seat upon which my PLM2000 mill will set, after removal of everything screwed down to its top. It looks deceptively weedy in the photos but it's around 4 feet tall. Took three people to get it into the truck and we had to tilt it up on one edge then down onto the tailgate to lift and slide it in. Cost? $300 cash money. :) Some of the other parts may migrate their way into a 3D printer I'm wanting to build. Need to do something with the 30 feet of 40x40mm aluminum t-slot extrusion and various corner plates and angle brackets I've been given. --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
