Atlas Horizontal mill

I picked up an MFC for $330 back in December. Luckily I had a friend in Ma to pick it up and ship it to me, still waiting on it. I also picked up a vertical head that runs off of the arbor via a belt for $150

SCOOOOOOOOOORRRREEEEE......

Looks like it is in good shape too! Where abouts in MA did it come from? Perhaps it was in my backyard and I never knew!?!?

And a vertical head for 150 too?!? Some guys have all the luck
 
It came from Dartmouth. The guy even delivered it to my friend in Norton at no additional charge. I was the 3rd to win this bid. For some reason, the other 2 backed out.

I've since bought all of the guards (including the vanity guard over the arbor), and each of 7/8, 1, 1-1/4 arbors.

I should have a fairly complete setup now, just need some cutters.
 
Wow, it was in my backyard! I'm in New Bedford. There was some cutters in the Rhode Island C-List in the past couple weeks.
I've been able to find some up the cape and did well on the purchase. I still need a 1" arbor and spacers, I have the other two, but I was just give some round stock so maybe I'll make my own?
Maybe we can get together some weekend!
 
There is nothing wrong with using a 1-1/4" arbor on the Atlas mill. The ones that someone used to run on eBay appeared to be well made. But just for the record, the factory only supplied 7/8" and 1" ones. So if you have a bunch of 1-1/4" tooling and have the misfortune to damage the arbor such that it can't be repaired, you may have a difficult time replacing it. So I would recommend sticking with the other two in your tooling acquisitions unless you find a large assortment quite cheap.
 
That's where my 1.250 arbor came from, as he was closing his business he started going wholesale, so the arbor was some 60% of the original price and the spacers was by the bagfull.
He even tossed in some extra spacers just to clear his inventory. I should've ordered the 1" right then because he was sold out by the time I saved enough pennies.

Also, I have a two piece "bushing" that mounts a 1" id onto the 7/8"s arbor. Works well for thin tools, won't work on a shell or slab tool.
 
So back on December 23rd I posted that my mill broke one of the u-joints, last week I started to investigate and discovered, I had shot myself in the foot!

What I discovered was that I had previously tightened the table crank on the left side, and once I loosened that nut, the table handle & shaft spun freely! I haven't gone any further on that front - but I did start turning some stock to make a U-joint. I'll have to change one measurement from the "home made" print I grabbed from here. Since the broken joint is right at the drive box, the shaft o.d. is smaller than the driveshaft itself.

More to come.

Wish I had known he was selling spacers by themselves. I would have bought some extra 7/8" and 1".

Atlas used to supply a shell mill holder. Mounted on the spindle like the arbor driver. I haven't seen one for sale on eBay or I would have bought it.
 
On his website, he was selling them originally by piece, then he was selling a bagful assortment of different sizes.
I guess I'll copy my 7/8" arbor but with 1" dimension and then figure out some spacers... or.... create a couple more bushings to adapt the 1" shell mills to the 7/8" arbor?!?!
 
We do have the factory drawing for the MF-27 U-Joint Yoke but it only shows drilling and reaming the pivot pin hole to 0.2500"/0.2505". And says that it is made from MF-26. All that we have on what I assume is MF-26 is several annotated photos. And the OP warns that the measurements might not be dead on.
