that's awesome. It's a great color, especially for award and award-adjacent stuff.

Used the Schoolhouse Spools' Pearl Gold PETG that @jeepxj seems perennially out of now to make a medal rack for my lovely wife's running medals:

If I'm getting volts on all three legs because of the main motor backfeeding, then the motor for the speed change drive is surely borked, as it'd be getting the same. I'll likely wire the VFD to the high speed winding, knowing what I know now, and use the speed control from the VFD, as it'll...

I'm not certain that I'm using a static phase converter. They lay claim to being a low-cost clone of the phase perfect stuff. When the motor is running, there is 208V between each of the legs. in any case, if I keep that to run the coolant pump, put a VFD on the 1HP spindle motor winding (or...

At this point though, I don't know if the motor is dead on the speed adjuster or not, so I guess I should work that out before I go whole-hog either way.

Purchased a '70s vintage Hardinge HC at auction. My bid was supposed to be a thumb in the eye of whoever won it, because usually tool auctions around here go to the moon, so I figured $1500 was reasonably low, so I'm calling it the Spite lathe. Tested the spite lathe yesterday with a "digital...

Want to run my Hardinge HC (1.5HP 3ph) without converting to VFD and figuring out all the stuff that's on the other input phases or asking the poco to run 3ph to my garage. Whatcha got for sale?

Even where I live in NM, where it's 5% relative humidity pretty much all year, I still have to go through a dry cycle each time I use nylon. It'll lose about 15-20% of weight just in the drying. I think it's just a matter of the nylon having higher water affinity than the desiccant.

printed a stand so that I don't have to figure out where to stick the sleeve while the record is on the turntable.

"Something for nothing" is what drove me away from the Z club a couple years back. The ratio of comradeship to freebie requests just got too damn high to tolerate anymore.

I published the 3 standard plates on thingiverse. Working on the 4 "special" plates, that take a .090" pin instead of the standard .136" pin, but I'm going to hold off publishing them until I make a .090" pin.

Second iteration on the design worked. The inner and outer tracks are reachable by the pin stop, and the lock holds everything well. I might up the "fudge factor" a little bit, as the fits are a little tighter than I'd like, but releasing it is more of a case of letting the perfect be the...

I use openscad. So, sort of? //dividing head plates diameter = 5.370; height = .250; centerbore = 1.752; bolt = 2.370; bolt_dia = .3225; bolt_head_dia = .455; bolt_head_depth = .158; pin = 0.136; $fn = 360; cf = 25.4; id = 3; od = 5.25; //tracks // 1 tracks = [37, 39, 41, 43, 47, 49]; // 2 //...

I won a Kearney and Trecker dividing head model H at the same auction I won my Hardinge HC, but it only came with plate 3 for indexing. Went through the manual and found the indexing hole counts for the remaining 6. Running a rough-cut at #1 now.

There are generational upgrades coming out pretty much every year. From color mixing to tool head swaps, the next few years are gonna be wild for the 3D printing ecosystem, provided that California and New York don't stop it all for their silly legislation. Everything new is focused on...
