ML7 Lathe

I know I am committing a mortal sin by starting another project before my other project (Admirable Nelson) is completed

but I moved over one of the additional Lathes that I picked up from the machine shop, a 1966-69 a Myford ML7 Lathe(I've gotten so used to typing Utilathe). Additionally I also moved over one of the two Medding's drill press.

So far I just did the preliminary tear down and semi clean so ensure that things are in order.

you will notice a layer of structural dust/grime on the entire bed way that is what seems to have gotten the carriage stuck.

Ye Old Problems

Seized Spindle
Seized Tumbler gear(smaller one)
Seized Cross slide
Seized Carriage(there seems to be a theme here)
Seized Tailstock quill
Seized Compound slide
Top half of the lead screw has rust
Oilers are busted
motor state (I am unsure of as of now, but ill just add it here for good measure lol)

so there has been some progress
the lathe cleaned up really well given the state that it was in, the dust itself protected the rest of the machine from heavy corrosion but also locked everything in place.

Seized Tailstock quill

Additional Ye Old Problems

worn oil lite bushings in apron
seized backgear mechanism
bent cross slide screw
missing compound hand wheel
missing oil zerk on support for lead screw


I took everything apart and cleaned it that sorted most of the seized stuff but parts are worn and badly so in some cases.

Wow good work!

Are those the original belts? It looks like it took some serious effort to pull that belt tensioning lever forward. I'm not sure if its just the belts are tight/short on your lathe or if that pivot is seized, but on my previous ML7 and my now ML7R, that lever was never that challenging to pull forward.

I don't think they are the originals and the second one in the spindle needs to be changed it is what was responsible for that ticking sound, also I'm not sure about the adjustment on the lathe is correct either

I had forgot to mention that the original motor will need to be professionally looked at, corrosion was detected on the internal leads so I had to sub an old washing machine motor in its place
