Cunliffe Horizontal Milling Machine

[Reeltor]

Brian,

I'm afraid that if I tore down a machine like that it would remain in milk crates forever. I am in awl of your work on this mill.
The mill is in remarkably good condition; especially after seeing what gunk was in it.
One question; are you sure that all of the zerk fittings should be greased? I know that may older Bridgeports were ruined when an oil zerk was greased, and starved surfaces of lube. Guess what I'm saying is, just because someone in the past greased the zerk doesn't mean it was correct.
You are doing a great job, I look forward to seeing it run!

Hello Mike,

Thanks for your kind words... I'm just learning as I go along.

That's a good point to make about the zerks. No, all of the zerks are oiling zerks. The only spots that get grease is the motor bearings and the rear clutch mechanism has a grease pot. My manual has all of the lubrication points clearly marked although, all of them on this machine were thoroughly greased, as you suspected. As I go through each component, I clear out the old grease and ensure that oil will freely flow through the zerk and passageways.

Once I get the bearings and seals installed and the transfer case sealed and back together, I will move on to the saddle. There are also some gears and bearings that I will have to pull and inspect. Once the saddle is cleared the mill will be ready to go back together. I have most of the other sub-assemblies already cleaned and oiled and ready to go, so it shouldn't take too long.

Hi Jeff

Thank you for your offer. I might have to take you up on that if I run across another original bearing that I can't source locally.

Cheers...

Hello Mike

Yes, slowly but surely.... While waiting for the bearings for the transfer case, I decided to take the saddle gearing apart.



Lots of brown muck, but once I had it cleaned up some, it was obvious how the gears came out. The gears are in good shape, but one of the bronze bushings is wallowed out and the shaft is badly pitted. I have a new bushing on order and will make a new shaft once I press in the bushing.

Well, I finally received my bronze bushing and went at repairing the saddle. The shaft took some time, as it had quite a few exacting features to machine, and I only had 3" stock to start with.

Here's a pic using HSS ...



And here's a pic using carbide at .070 DOC. Chips were just pouring out and the finish was real nice...



Here's the finished shaft and bushing, ready for installation. I had to shorten the new bushing, as well as machining oiling grooves... (not the internal spiral grooves)



Here's the finished repair...





Now I'm just waiting for my bearings to arrive, so that I can complete the transfer gear box repairs.

Hi Brian
Just read your entire post on the milling machine. What a great adventure you have taken. Looks to me like you are going to have one fine milling machine.

Hi Martin

Thanks very much... I am still trying to chase down the last two bearings that I need, then I can finally move forward. The bearings that I had ordered from Canadian Bearings look like they won't come in until at least July, so to Ebay it is...

I saw that awesome lathe that you purchased recently... I am quite envious...

Thanks,
Why so long from Canadian Bearings?
