Cunliffe Horizontal Milling Machine

Well, these angular contact bearings were apparently coming from Europe and for whatever reason, they have been backdated for shipping. I did find what I needed on Ebay and would have went that route had I known that after waiting for nearly 6 weeks, I'd have to wait until at least July.

Hello all :)

I finally received the last two angular contact bearings.

They are NOS and the staining is from the old grease paper.

I wasn't sure just how the bearings were supposed to be oriented at first, so I did up a rough sketch to get my head around the forces on the bearings and how they are supposed to work.

I now have the transfer case back together with new seals and bearings throughout. I couldn't find what I needed in a thin gasket material, so I went with a gasket sealant. Hopefully I have the proper clearance for one of the shafts, which relies on the cast iron bore as a bearing surface. Before I put it back together, I placed that shaft into the housing with lots of oil on the shaft and bearing surfaces and closed up the case, tightening the bolts without anything between the case halves. The shaft rotated freely, so I should be all right. I will fill the transfer case with oil this morning and see if it leaks or not.

Here's the transfer case mounted to the saddle...

I also installed the tapered gib for the saddle and have it roughly adjusted for now...

Not a lot of progress, but a bit of a hurdle has been overcome. It should be rather straight ahead in getting the mill back together now. I will have much more incentive in finishing up the job, because, like the fool that I am... :eek: I am heading out this morning, with trailer in tow, to go look at another machine.... I never seem to find plug and play machinery. They always have to be fixed up.... but I guess that I find it really satisfying in getting a piece of machinery working better than when I got it.

Sucker for punishment... :)

Well, I'm back after my road trip... and, sadly.... not empty handed... ;)

Here is my latest "project" ...

IMG_0252%20800x600_zpsz578v9q8.jpg

Here it is, safe and sound in my driveway...

IMG_0256%20800x600_zpsooq8bzam.jpg

Here's the serial # complete with a U.S. Navy war badge... spent some time in the trenches, I suspect... ;)

IMG_0258%20800x600_zpsemdquyah.jpg

This is, I suspect, a 15" x 36" South Bend Tool Room lathe from the mid forties. Unfortunately, some cheap bugger removed all of the brass information plates, as well as the bronze/brass tumbler/reverse handle 'cause there was lots of money in scrap... :rolleyes:

I checked out the wear on the ways, and as near as I can tell, there is around an .008" drop from the tailstock end to the headstock. This lathe will need some TLC. I will open up a new thread in the appropriate place before I discuss this lathe any further. I'm just having a celebratory beer, before I head down to the shop and figure out how I'm going to get this lathe off of the trailer and into my shop.

Cheers... :)

She's a beauty. I'm wondering If anyone has figured out a rig for grinding your own ways, by working off of one true or shimmed true surface of one of the ways? Guess I should google it and find out. Mike
 
To answer my own question, I found this pic. Has anyone here tried this? Mike

Very good looking lathe! Looks like a lot of good times ahead.
Cheers

Back again... :)

I ended up using my 2 ton shop crane and took the lathe apart, piece by piece to get all of it off the trailer and on the floor.

Back to the mill... Now I have even more incentive to get the mill back together.... I'm running out of real estate and I can't have two projects on the go at once... :eek:

I had a bit of an oil leak in the transfer case, but it looks like I have that solved. There was some free time this last weekend, so I started putting parts back onto the mill.

First thing was the cross slide components...

IMG_0306%20800x600_zpsuhznhl7z.jpg

The cross slide feeds didn't work before I took things apart, but by manipulating things mechanically, everything works as it should. The transfer case overhaul was well worth it.

Next was the components on the left side of the knee. There are two limit switches, one mechanical one for the cross slide and an electrical one for the knee. In addition, there is a lever that coordinates the knee feeds and the cross feeds, which was frozen before, but now works like a charm...

IMG_0313%20800x600_zpsmqapn42c.jpg

Next to install was the compound table swivel...

IMG_0309%20800x600_zpsrinjn2dp.jpg

The compound swivel table is held in place by 4 sets of double set screws and four 1/2" ball bearings. I replaced the ball bearings with new ones and adjusted everything to a nice rolling fit, without any play...

IMG_0311%20800x600_zpsxorfuifj.jpg

Next was the electrical control boxes for the rapid traverse and limit switches...

IMG_0312%20800x600_zpsyubfir5w.jpg

Lastly, I installed the oiling cups at the back of the compound swivel table with new wicking and will wait to see that they are all working properly before I install the rest of the components for the table...

Hi
Looking good, it will be like a new machine in a bit, or better LOL

I had yesterday come as a surprise day off, so down to the shop I went to try and finish up the mill. The wicking was working very well, so I then installed the central feed gear assembly and feed change mechanism and lever...

IMG_0317%20800x600_zpsidicgryn.jpg

IMG_0318%20800x600_zpsdb0c6jrt.jpg

Next, I installed the split nuts and bearing caps. The split nuts are held from rotating by a woodruff key that also allows the nut to slide back and forth to allow backlash adjustments...


IMG_0320%20800x600_zpsviphzxua.jpg

IMG_0319%20800x600_zpsvf7j5j7q.jpg

I then temporarily installed the lead screw, to make certain that the split nuts were timed with each other and most of the backlash taken out, as well as the key in the feed gear arrangement was aligned with the keyway in the leadscrew, before installing the table,,,

IMG_0321%20800x600_zpsksc4twtl.jpg

Here's the table going home...

IMG_0322%20800x600_zpsj0ojczqq.jpg

IMG_0323%20800x600_zpsw7dnt4db.jpg

Once I had the end bracket installed, I wound the table to the far right to further adjust the backlash in the leadscrew...

IMG_0324%20800x600_zpsdzttiozh.jpg

IMG_0325%20800x600_zpsq6av8yj9.jpg

With most of the remaining parts installed, I just had to power up the mill to see if my repairs were successful. Yaaaaaahhhh... !!!!! Both the X and Y power feeds and rapids work smoothly and flawlessly, as well as all of the limit switches performed admirably...

IMG_0326%20800x600_zpszlcon1ss.jpg

Just a few small parts to install and the mill is complete.

Cheers... :)
