So a bit jelly here as I would have some cool ideas but anyone used/ have one of these?

Its like a rotary head for the mill - the “Inheritance Machinist” uses it in the last video. Prices “used” seem crazy canadian$$. Any knock offs??
 
cool, interesting if you want to cut circles in thin stock. arcs too I guess.

But at that price I'd think of a way to use RT to accomplish the task.
 
Thats cool. Like a manual k&t 2d

Kearney and Trecker #2D Rotary Head Mill

My home machine shop is a retirement dream that I have been assembling for 60 years. One of my many prize possession is a 1952 Kearney and Trecker #2D Rotary Head Mill. Displaying old verses new technology,,, and sits directly across from my CNC Bed Mill. Indeed being nostalgic is why I have the...

FYI a circle is one line of gcode. The better mousetrap.

While I admit I never really had all that much experience actually USING a rotary table, maybe a dozen or so times. Back when I was a designer in my early days I used to have to generate prints for the old toolmakers so they could make stuff on the rotary table all the time, because we did a lot of that stuff manually having only 2 cnc's that were too busy cutting more complicated stuff. Fast forward a few years when I started getting some CNC experience, I was instantly like "I'm never touching a rotary table again :D. And I didn't, maybe 2-3 times since then. But now in the home shop there have been many times I wished I had one, and have been trying to find a nice 10-12" one for a while now. I'd probably use it quite a bit at home, and I have a CNC sitting right next to my manual mill. I'm actually starting to enjoy cranking handles a lot more, and I never thought I'd say that lol.

These heads are pretty cool though. Not sure i'd have a use for one other than for the experience, but you can be sure, now that a youtuber has showcased one, the prices will be through the roof on whatever limited supply there is out there. If you've got one tucked under a bench somewhere, now's the time to unload it.

Did you see this Dan, looks nice, very similar to my News and shipping might be a possibility.

Ya, I spotted it when you posted this morning. Looks in great shape and a great price too, but sadly not a H/V like I want. Also one of the rare time a deal pops up in the neutral zone between east/western guys, so good for them......I'd almost feel guilty as an Ontario guy snatching one out from under their noses.....:D I used to use the exact same one at work, but ours was in MUCH worse shape, and missing the plates. That one looks brand new. A deal for whoever buys it for sure. I don't deserve to own anything that nice lol.

Right now isn't a great $$ time either, Been out of work for most of the year, and only now starting to get back on my feet with a bit of cushion again. I'd have a hard time justifying the $700 for a rotary table right now when other things and projects could benefit from that money. There's a guy (Cowan Machinery) just east of me that deals in used equipment that always has a few available. Some are pretty rough, but would clean up good enough for the majority of my uses. I just don't really have an immediate need right now so it'll pay to sit tight and be patient. Something will come up that ticks all the boxes.

and for sheet stock even a decent cnc router will do.

I just saved $1700 to put towards my cnc router.
 
I know some Volstro’s (maybe all?) use an ‘E’ collet, not an ‘ER’. A little fact to know in case buying one without collets.

Yeah, no kidding!

IIRC, they called that Volostro unit a Cherrying Head. Was used mainly, for putting a radiused corner on an injection mold, while using a really basic Bridgeport style mill to accomplish the act. Lots of light cuts, usually with fairly small milling cutters.

Sorta like looking at clocks and watches, or mathematical Calculators. Much better results can be got SO much cheaper, but a fella has to respect the tech that got it done, before the current stuff got so easy to afford!

I learned to REALLY respect the capabilities of a rotary table, when I did a so-called "Advanced Machining" course, in the military. Wasn't really all that advanced, just a short and sweet run though a LOT of manual machining capabilities, that we were not really already aware of. We made eccentric cams with up to five different radii, both internal tracks, and raised External ones, using clamps, parallel bars, and Gage blocks to do our offsets. We got VERY proficient at dialing in our zero on the center of the R/T! Like, after every coffee break or meal time!

One project we did, was we partnered up, and made a quarter circle Dovetail joint on a 4x4 block of Al. Part of our SOP, was to set the rigging up, and drill and bore a center hole, at near as possible, half inch. So my partner and I started out and we made the pair of dovetails. When we tested them, they slid together perfectly, then when the instructor pulled out his half inch Dowel pin, it slid through the two holes like it was meant to be there!

CNC is wonderful stuff (esp. when paired with some decent software!), but a fella could do a lot worse than at least, to understand how things were done before it came along. It'll make a fella appreciate what he has, more! IMO! :P
