Just got a new-to-me Spanish-made Enco 12" vertical/horizontal rotary table!
And man, did I score a good one....
I purchased this RT at an auction for the shop tools of a high school a few hours away (bummer that it was shutting down its shop, but that's the way of the world it seems). I didn't have the time or desire to drive all that way to inspect, so I figured I'd take a bit of a gamble and bid on it, sight unseen, based on a few photos (the two below plus a few more). I reckoned chances were high that it was beat to hell, as it was coming out of a high school. I was high bid. And after fees, taxes, etc., I ended up paying $220 for it.
I just spent the last couple evenings completely disassembling it and cleaning it up. And boy howdy, thing is CLEAN. There's not a single apprentice mark on the entire thing; not a single drill mark in the face, absolutely zero wear anywhere. The circular V-way was scraped in (or at least flaked) and there is zero evidence of any wear there either. The more I dug into it, the more I became convinced that the high school bought it, stuck it in a corner, and never used it. Seriously though, I would honestly be surprised if it was used more than 5 times. Ever.
Now, the best part! A few days after I won the auction (but before I got my hands on the RT), I got a letter in the mail from the auction house, saying they found this while doing some clean-out. How cool! And really, really nice for the guys to send it over my way. The hand-written test card shows the angular deviation all the way 'round the circle, and concludes it's +/-24" to true. For reference, here are some claimed rotational accuracies of other similarly sized tables:
Moore (Ultra) -- 4"
Moore (Standard) -- 24"
Yuasa -- 45"
this Enco -- 48"
Troyke -- 60"
Phase II -- ~80".
So it's good, it just ain't a Moore.
It looks damn huge sitting on the table of my Bridgeport, whether lying flat or standing upright. And the thing weighs a ton (well, about 170 pounds actually). I'm a young, fit guy, but holy cow, that's a lot of weight to lug around! I certainly couldn't lift it from ground level up to the mill table without putting my toes (and the RT) in serious jeopardy.
By the way, the number "19" was stamped into both the base casting and on the underside of the table. Is this really the 19th one of these made? Based on the calibration card, it was born in June of 1980, so it just turned 40 years young!
The worm/gear set is a 90:1 ratio, so one handle turn equals 4 degrees. It's graduated in minutes, with a vernier reading to 6 seconds. As a special bonus, it has 36 direct indexing detents around the perimeter to accommodate a spring-loaded pin. Definitely will be a time saver if I want 2, 3, 4, 6, 9, 12, 18, or 36 divisions.
So what do you guys do with large rotary tables? Leave it mounted on the mill table? Or only install it when you need it? I'm going tomorrow to check out one of those Hoyer-style medical lifts, which are quite a bit smaller than a regular engine hoist (capacity of 400#). Priced reasonably, so unless it's not working, I'll probably snatch it up.
Anyway, I simply could not be more pleased with this purchase. Other than some flaked-off paint, the thing is essentially new.
