Atlas horizontal Mill

Just wondering if anyone else here has an Atlas Horizontal Mill? I recently acquired an Atlas MHC. It was completely restored a few years ago and has seen almost no use since then. It looks almost new. It has an original vise (3 1/8 inch) and a significant number of cutters, a few end mills, end mill holders, 2 arbors, over arm support, knock out bar, a large assortment of clamps, etc. I plan on acquiring an original Atlas rotary table (4 inch I believe), indexer, a small chuck (1 x 10 thread) and any other original parts that I can find. This will probably take a few years to find all the stuff. In the mean time, I am wondering what accessories that other Atlas Mill owners are using.

I have a small dividing head (Enco) that will just barely fit on the small table and intend to use that to cut some small (1-2 inch) gears. An original Atlas indexer will probably cost more than the mill but I would like to complete the setup.

This is my Atlas Horizontal Mill. I haven't used it much and would like comments about the strengths of the small horizontal mill. I also own a Bridgeport J1 that I am rebuilding.

Phil,

The stand looks like an original Atlas stand for one of the short bed lathes, maybe a 24".

Hi Robert -

Yes. Standard issue Atlas. I just really like the way they look. I saw one for sale somehere online earlier this week that said it had been under an Atlas shaper. I don't recall the specifics as it was too expensive and too far.

The stand under the South Bend 10K ("Light 10") came with it when I bought it from the local University machine shop. I assume it was original, since I've seen many pictures of older South Bends with identical or similar stands.

That stand was a stock catalog item for use with the shaper, mill or 618 lathe.

Here is one under my shaper

I just finished the rebuild on mine that I acquired 4 weeks ago. It came with the original vise, small rotary table and what I think is the original tiny indexer and 4 plates. Lots of end mills and cutters for the horizontal but I did buy a 1" arbor since 90% of my cutters had a 1" bore. It also has a unique vertical head that is a dream to use. Just some wiring issues to work out then the chips will fly!

Hi Gramps -

Beautiful restoration job on that mill! You may already be aware but if you are thinking of wiring the switch in the original location, Clausing still sells the switch plates inexpensively.

Thanks for the compliment Phil. I have a new switch and plate but I am planning on using the original location and screw holes to mount an electrical box with a combination receptacle and switch so I can plug in the vertical head when using it or the light which isn't mounted in the photos. I'm still toying with what I want so currently extension cords provide power!! This is a nice little machine for the hobbyist and with the vertical spindle I have quite a bit of flexibility.

WOW,

I have not seen the verticle setup before. I wish I could find one for mine. When I got mine someone
made a 90 deg aluminum geared setup that mounts on the support post and drives from the horizontal
spindle. I don't think it has enough mass as it don't work very well. It will chatter with even a small
2 flute end mill. I can just get by with a small 4 flute. I am new here and need to get a camera. I have
some interisting stuff to share.

The elderly man that owned this was a toolmaker and made all the mounting hardware, pulleys etc. I have no idea where the spindle came from but it has an old Clarkson Autolock Type "C" collet for end mill holding. There is even a power feed setup for the vertical spindle which I didn't install because I never plan to use it. The potential to wreck some very hard to find Atlas mill parts is too great. I can do a lot of hand cranking rather that smashing things up! The nice thing about this unit is it has its own motor so I'm not wearing out the Atlas drive system when vertical milling which in my opinion is a big plus compared to many other units.

I have been there done that too. Here is my Atlas that I restored a few years ago. I still have a few small tweaks to make here and there, but overall I am quite pleased. The vertical attachment takes #2 Morse taper collets. I do enjoy the machine quite a bit and have never regretted buying it. I also have all the horizontal stuff to use it configured that way as well. I really admire that other vertical conversion a few posts back, much more clever than mine. That one has so much more clearance to actually get some work done. I might have to make some modifications to mine based on that!

I'm finishing up the restoration of one of these. The motor is fitted with a single belt pulley and I want to get the right sized step pulley mounted. I can't find any info on this. Could somebody who owns one with the correct step pulley measure it and post it up? Thanks

The outside diameter of the large step lip is right at 4 1/2 inches. The outside diameter of the small step lip is right at 2 inches.

Hope that helps,

Earl

HalcyonDaze,

Depending upon your motor shaft diameter, the pulley is either a 9-428 (1/2" bore) or a 10-428 (5/8" bore). The same pulley is used on the Atlas (and Craftsman) 10" and 12" lathes. If you are looking for an original, you'll probably have better luck checking the lathe ads than the mill ones. I'm pretty sure that you can still buy the 5/8" bore one from Clausing, although I don't know the price.

If you end up having to make one, in the Yahoo atlas_craftsman and atlas_craftsman_projects Files sections you'll find some information on pulley making and a drawing for making a 10-428. According to that drawing, the two diameters are 4.390" and 1.930". I think that the drawing was reverse-engineered so all of the dimensions may not be exactly the same as those on the Atlas 10-428 drawing. If you need the drawing, its on the _projects list under Drawings, Atlas or Atlas-Craftsman Machine Parts. If you can't get to it, let me know. The pulley making info is on the main list.

That's some good information right there, Robert. I'll check for an original first, if I can't find one I may have to take you up on that offer. I'm not a member of the Yahoo group (though I've heard a lot of good things about it). Thanks for the help!

Now off to fleabay...

I just purchased a Grizzly GO727 not to long ago I was so happy with it I sold my Atlas mill that needed a lot of work. After seeing some of the nice modifications I wish I would have kept it and restored it for something to do over the winter. Ray

It definitely WAS a steal even without the vise but an original like I have will probably cost you as much as the mill if you find one. I've seen a couple come up recently on Ebay. Keep an eye there.

O started out with an Atlas mill. I recommend that you definitely rig up some kind of support for the outboard end of the arbor. The originals had one. It secured around the shaft of the "Y" handle feed,and connected to the overhead arm. It has to be height adjustable. This would greatly help the jumping and grabbing that happens with these small mills.

Do you think the jumping and grabbing is the arbor moving or the table moving up and down on the screw? There really are a couple of causes for the movement but at the moment I find if I use the travel locks in the two directions not needed to cut, the vibration is greatly reduced.
