overkill for the size of the lathe maybe! This thing is almost as long
I'm pretty sure machining epoxy will be no problem.
I have machined acrylic and the fusion point was pretty low. Turning too fast melted it. Yet, a Q-Tip with some petroleum distilate as a lubricant was more than enough.
Worst case scenario... put the epoxy in the freezer for a while!

Probably direct translation from French, in Spanish melting point is "punto de fusion"

Ah, that's what I was thinking. Because there's "heat of fusion" in English, but we say "melting point," which is what I think he means.
Could be a fun way to trip up people

The cooling system is interesting but looks messy... also, do you really mist your expensive machinery with water

Not messy at all. Fairly precise and civilized actually. Sperate mist and air control. They are used with concentrated water soluble synthetic oil that prevents rust. A few ounces of concentrate mixed with water makes several gallons of coolant / lubricant. I would guess that on your lathe, a few gallons of coolant would last for a year.

I've got this utterly wunderbar book about general machining for the tech school library, "The Amateur's Workshop".
I now believe lathes are female, considering how well they multitask.
I started writing this post before Velocity and LeMaudit posted, but trying to insert a url didn't really work.
I'm getting my information from a rather old book, I've only seen a cutting oil mister before.

No....That's a COOLANT misting unit.

Probably not, considering they seem to perform multiple roles but actually do each of them
well

Not really, but not because of any rust risk. I have a coolant pump setup on my lathe which uses a synthetic oil that's made up with water for cutting with. If I did use water it would simply mix with dehydrated oil around the lathe. However petroleums are a better choice. A can of degreaser, WD40, kerosene, oil, etc. will work. Look up a chart of lubricants, some metals will work better with different lubricants.
BTW, your equipment should be kept well oiled, which is going to halt rust and will keep it running smoothly.
Here's a little knife I just made, inspiration kudos to LeMaudit. No prize for guessing what it is

Edit: Btw, it's 12cm long

Not even a small one
Nice job!
Cutting up some inner tube to put between the lathe bed and the table, who knows, maybe I'll be able to machine at night without waking anyone up

You probably will be able to machine without anyone noticing, my sherline is very quiet along as you can avoid chatter, not waking people up will be a little extra motivation to get your speeds and feeds just right.

Agreed, it really doesn't make as much noise as I imagined.
Anyway, just came back home with some stock, good deal for 50 euros/$70?
A bit of recalculation to adjust the plans for metric and I think I can start with the pen gun
