Just got my first real mill off the rollers and started cleaning. Came with arbor and supports. Would like to use it to cut splines and possibly find a vertical mill attachment.

If you tilt your head down and look at the table of your horizontal mill, you will find yourself looking at a vertical mill, well, kinda'...

His machine isn't a duplex machine like a No. 12 or No. 22. It's just a horizontal milling machine.

Van Norman did make a "Heavy Duty Vertical Attachment" and a "Universal High Speed Attachment" which would work on a No. 2 and give you vertical milling capabilities.

Staring at this I think the simplest solution is to make an adapter on the overarm to a bridgeport type head.

Found a #40 Chain 2-1/2"Dp off the shelf part I can turn down to fit for $15 to my door. Just need to machine the bore and press in a oilite bearing.

That was quick.
Now to turn down and press in an oilite.
Must have worn down off ce 20180405_132249.jpg nter. Chain still looks ok. Might make a chain stretch guage to check its health.

Sounds good to me , I think I'd do a couple oil catch grooves in the bronze bearing . Only needs a few thousandth grooves to hold oil in it. If the bearing fit is tight it won't let oil in till it heats up . Like scraping on the ways it's to hold oil .

Note these replacement gears are hardened. Its been a pain to cut using carbide. Seem the most the atlas will suffer is 0.040". I'm getting a mirror finish but this is tedious.

Is that roller chain drive for the table feed? My VN used a silent chain drive (that I found because it was making noise) that uses weird triangular-toothed sprockets.

That’s a beast of a machine!

Motor, belt, intermediate shaft, chain drive, 90* bevel gear set, fluted shaft, knee feeds.

I tried to post manual but it wouldn't take.

Scraping marks look good. Bijur clogged in a bunch of places. Lead screw only comes out to the left but I need a 3 jaw to pull the right side stuff off.

Been trying to get the lead screw out since last posting. I may have to cut off dials on the right side. Tried penetrating lube, hot/cold, pullers, pickle forks, percussive maintenance ect.

Also the picture posted does not match the diagrams.

There were a few chips in bed as well as signs of water intrusion but no real damage. So I think I need to give all ways a good cleaning.

Got it off. It was staked on. Used heat cyling, liquid CO2, pickleforks and hammer, as well as a bearing puller. Did a little more damage than I'd like but there was no other way.

Upnext its removing table from knee. Have to figure out how to disconnect power feed
