tried to machine titanium

As a pyrotechnician, I can also tell you it's HIGHLY flammable. Keep it wet with coolant always. I've seen the aftermath of "dry cutting" on Ti, and it isn't pretty when a large pile of chips ignites!

Well... it IS pretty when it's in a pyro effect, but not so much on your lathe chip pan!

And do not, should it catch fire, put water on it. No joy: steam explosions and burning underwater.

C'mon, Gunner! A Sherline IS a "real" lathe. It's not a GOOD lathe, but it's very, very 'real'.

Yeah... but you can touch it. It will turn. It will make crude things that look almost round.

It's 'real', just not _desireable_.

In Wieberworld a real lathe sits unused because it's a gearbox-busting blanket-magnet. A real truck sits in the shop waiting for repair money to be scrounged. A real wife has multiple boyfriends. A real house arrived on wheels and sits on a rented lot. And a real mind lies to itself and everyone.

Need real space first.

For small parts, it's the right tool and it works great.

I agree. I do not have a Sherline lathe, but its reputation is that if you don't try to over work it the work it produces will be good.

Pencils? Why? Pens are the way to go. You make pencils by extruding wood goop around a core.

Its like saying a Taig 2019CR isn't a real mill or that its bad. Its good at being what it is. An inexpensive small mill for making small parts. I made tens of thousnads of dollars worth of parts on my Taig, and it paid for my next couple machines. It didn't make any of those parts very fast though.

Yeah... I even have a little Unimat on the shelf. I use it only seldom, but I've made some nice "microscopic" parts on it. The only drawback is that I use it so seldom, I often have to replace the O-ring belts before it will work again!

LLoyd

My old mentor at American Machinist, Bob Hatschek, used a Unimat in the only production application I've ever seen for one. He made a little aluminum and brass gadget known as the "Hatschek Hook," a release hook for high-class model gliders. It weighed a fraction of an ounce and it had quite a bit of machining on it, all done on the Unimat.

Bob sold over 1,000 of them, worldwide, to model glider competitors. It wasn't cheap.

At least it cancels any misconception that metal is infinitely rigid.

At Mitre I acquired a Sherline and a Prazi clone from closed labs (a bad omen). The Prazi was large enough to be useful though I dislike its controls. I couldn't learn to like the Sherline for anything. It fit in a drawer and there it stayed. I can do tiny delicate work in brass better on my 10" South Bend.

Leave the "safety cover" open, and the "O" rings will run cooler and last longer.

I guess you didn't read my post. I never run it long enough to wear any out.

Which Unimat is this which has a safety cover? I've used the early ones (two models, but the same steel rods for rails) which had the pulleys out in the air -- ready to grab a careless fingertip. :-) Trying to remember those models -- DB-200 and SL-1000 IIRC. Yep -- verified.

Enjoy, DoN.

Yes. Yes it is. He should at least get an HFT lathe.

Your word is worthless.

You don't have a shop. You have a poorly enclosed carport with a dirt floor and a rollup door that someone threw away. You "engineered" a sad and ugly installation, your trademark.

How many months is that? I had a serious failure of my own truck. Put it on the hoist, diagnosed the problem, picked up the parts. Next day installed them, back on the road. Strange how the people you claim are incompetent can do the things you have to pay others to do for you, eh?

Too bad you couldn't afford to hire someone competent.

How the f*ck would you know?

It could have been decent if it wasn't installed on such a s*it lot and didn't have pigs living in it.

I paid $10 for a unimat at a yard sale and a couple of years later sold it for $900 on ebay. Could have knocked me over with a feather, but the guy really wanted it and really paid for it.

Not sure why this sort of becoming a pissing contest.

Call it what you whatever you want, but I've been able to make all sorts of useful stuff I wasn't able to before with the small lathe and mill. Hypothetical machinery you don't have really doesn't get the job done.

One guy I know uses pre WWII looking old leather belt driven machines to make parts for export to Germany. It's an eye opener in what can be made with what might be considered (they're real pretty though) laughable tools.

That's about right. I already work full time, this is all for fun.
