Getting it spinning again.
Hello Hello again,
I was wondering if anyone had any tips in getting a wheeling machine spinning again. Its a traditional style of wheel with the shaft running from the top wheel to the back with a bearing at the front of the machine. It spins but it is very stiff, ive greased it up but it is still very stiff. Any suggestions would be greatly appreciated. I can only think of a new bearing. Not sure though, Cheers, Robbie

in presume it is an cast iron wheel if significantly old probably Babbitt bearings
if not bronze you probably need to remove shaft and you have rust in the bearings or galling from lack of lube |

Lubing
I don’t know what style of machine you have, but in cases where we have stuff that’s locked up, we’ll soak it in a bucket of diesel fuel or kerosene. So if you can, take a bucket and support it to soak the parts.
But I do agree Ken, your goal needs to be disassembly, cleaning and lubing. John

Acetone and Auto Trans fluid 50/50 mix really effective.

Robbie,
2 wks ago, I brought home my new-to-me but very old circa 1890 Putnam metal lathe . It turned smoothly but had some resistance. After blowing out all of the oiling holes with compressed air until they were as clean as possible, I used a lot of penetrating oil (liquid wrench because it was handy, but otherwise would use 50/50 aft/acetone) until it flowed relatively clean. The early stuff did flow very dark before flowing progressively cleaner. It flushed a lot out. I kept turning things by hand to draw the penetrating into the oiling holes. I followed the clean penetrating oil with regular oil & more turning by hand until it dripped out and now it spins very well and easily. With a good twist by hand, the Headstock will now spin 2-3 revolutions by itself. The smaller shafts/lead screws also improved significantly. The overall lathe was cleaned with only kerosene before I addressed the oil holes. I tried hard to avoid washing any trash into the oil holes or unplugging them at all. My lathe had apparently never been left outside and shows no play in the shafts or headstock, so I'm not as concerned about rust and poor babbits or bushings. Maybe yours will free up like mine(?) maybe not.

Yeah, it spins by hand but it won’t spin on its own, which I need it to do. The bearing has been oiled and looks to be in a decent condition but perhaps that shaft need cleaning.
I’m not very mechanical minded but it seems there is to much weight in that one bearing to spin that whole shaft. 🤷
