Emco-Lux adjustable tool post/adjustable lantern post
|
Does anyone have experience with the "Emco-Lux Adjustable Toolpost" that was advertised in the Campbell Tools Co catalog for March 1983, entitled "Lathe Accessories and Attachments" (see here and screen shot below)??
?
Last September, one of these was for sale on Ebay and Mr. Pete has one video () explaining how he went about adapting an incomplete such tool post. Apparently, this "Emco-Lux" toolpost has never been very common - I never saw one thus far, and references are isolated - like .

It looks very similar to the "Lantern" or "American" style tool posts that were installed on probably millions of lathes in the USA in the past century. They work very well for most people, and are more versatile than a tool block or QCTP for some operations. There are quite a few things the tool block or QCTP are better for if you're doing production work. IMHO, any well equipped shop should have both.? The proper Lantern style has a dished washer and rocker to fit it that allows adjusting the angle of the cutting edge to the work. That's both advantage and disadvantage. You don't have to grind tools to specific angles for different materials, but it's also very difficult, or more accurately impossible, to get a repeatable angle. If you're working near the limits of the lathes material size it's of great benefit sometimes, but it can also greatly reduce rigidity.? All my lathes have, or will have both by the time I'm done. My Atlas TH42 came with a lantern tool post missing the rocker. I filed one out of 7/16" (11mm) keystock. It's not perfect, but works. New or NOS rockers for that lathe are currently about $25-$30 plus shipping on ebay.com. A piece of keystock in that size is half that or less. For a Unimat sized lantern tool post 6-10mm keystone should be less costly in money... YMMV! HTH! Bill in OKC? William R. Meyers, MSgt, USAF(Ret.) Aphorisms to live by: Good judgement comes from experience. Experience comes from bad judgement.? SEMPER GUMBY! Physics doesn't care about your schedule. The only reason I know anything is because I've done it wrong enough times to START to know better. Expect in one hand, expectorate in the other. See which one gets full first.

¿ªÔÆÌåÓýThis tool post is listed in the 1980 Machinex 5 accessory catalog
as an adjustable tool post for the compound rest.? My Machinex 5
lathe has one factory installed on the compound slide.?? The
Machinex 5 was an American made lathe sold by American Edelstaal
after they lost the contract to sell Unimat lathes.?? Charles Daldry On 11/7/24 09:27, Herman de Leeuw via

Thanks for sharing your experience, Pat! Just wondering now about the rocker for the lantern tool post - would a half moon wedge do perhaps? These can be found in various sizes.

We had an SL1000 at work in the I&C shop for making bushings etc.? ?It had the standard tool holder, as well as two Lantern type tool posts, one plane jane and one rocker.? ?I have used both and prefer the rocker.? ?So when I got my first SL-DB I couldn't find a lantern type tool post so I made one using a 3/4 inch bolt for the body, it worked sort of, kind of a little rough.? ?I have since found one on ebay but not a rocker.? ?I also have unimat block tool holders in 1/4, 5/16, and 3/8" the latter two I had made on the Bridgeport at work out of 1" bar stock.? ?The machinists milled the slot, I drilled and tapped as needed.?

We had a rather extensive machine shop that we were allowed to use if we had time.? ?I learned a lot of techniques by watching machinists and apprentices.?
