I will say I am impressed at what is done on these little machines, by people with little or no background in metal work. I have been a machinist for 40 years now, and the technical side of my brain over rules the artistic side all the time and locks up! I am an over thinker. I will say since I have made two kitless pens finally I will be doing more on the metal lathe!

I use lube for Steel, sometimes I use a bottle applying a couple of drops or I can brush it on. The cutting oil from the plumbing dept for black pipe works well enough.
There are special inserts that cut aluminum really cut cleanly with little or no lube but you should use some lube to keep the aluminum from melting on bonding to the tip of the cutting tool or insert. Regular cutting oil, Trans Fluid is another, Brass 360 requires no lube for cutting.

As far as the lathe, an Er 32 (or larger) collet chuck is probably the #1 accessory (with collets of course.) A decent Quick Change post is nice. A set of changeable insert tool holders. THere are several different shapes, the triangles are the most common for the smaller lathes but I find the 55 degree diamond style better for me. A boring bar or boring set is also a good investment. Drilling is a good way to start a hole but not the best for a finished one. A good repeatable Drill chuck and a long nosed live center are really handy. I like the cnc profiled live centers. They allow you to get closer to smaller diameter work, that makes life a lot easier.

I agree with Charley above ....

... go for the LMS Hi-Torque lathe for the extra $300

I would buy the Hi-Torque instead of the Sieg C3 if I had it to do again.

Phone LMS and ask to talk to Chris who is extremely nice to talk to and can give you the complete and valuable advice that you need.

We are in the process of selling our house and moving to PA in the next month or two - pray for my house to sell! But with this move it will probably be 2-3 months before I actually get to use it!
Where in PA if close to oxford or reading you can visit my shop in north east MD.
I will be moving to the York, PA area. I will reach out and plan a visit! Thanks!

Default Very Useful Metal Working Mini-Lathe Website etc.

Just though I would post this for the benefit of folks interested in owning a mini metal working lathe. Lots of useful information here:

mini-lathe.com home page

Mini Lathe Tuning

Sieg Machine Tool Factory

This information may be available elsewhere on IAP but no harm in putting it here also.

Thanks for the info Mal. Do you know what the difference is between all those Sieg lathes and the lathes that Precision Matthews sells? It's so hard to figure out.

I have my mini for about 12 years, it took about 6 years to convince myself I needed the quick change tool post. That was the best thing that I added to the tooling arsenal.

I use ATF for cutting and cooling fluid and sometimes I mix it 50/50 with kerosene. A retired machinist suggested both. But my brain balks at using the kerosene mix, so it ot use very often.

Lewis .... sorry I don't know the differences, and not very familiar with Precision Matthews

Dogcatcher .... which QCTP do you have ?

The most useful accessory I have purchased is a 4" 4-jaw chuck (not independent jaws).

I had a C3 lathe, that was given to me by my brother (the Indian giver) till he wanted it back. I couldn't load it into boxes quick enough.
I had nothing but trouble with it, the gears inside are plastic, uses the same gears as the X2 mill, another piece of rubbish.
I went through about 4 sets of gears, 5 drive belts, 4 motor pulleys, 2 motors, 2 driven pulleys, a circuit board, and that much patience, it sent me nuts.
Even though I was using it very gently, no matter what I did it was apart more often than it was used.

That sucks! IF I had that much problem with a lathe, I think it might add a year to my life by giving it back. Giving it back might be a blessing in disguise! Live long and prosper!
