tried to machine titanium

[Cydrome Leader]

onlinemetals was having a sale so I got a foot of 1/2" titanium round in
"grade 2", whatever that is.

I tried it out on the Sherline lathe. The stuff makes stainless steel look
like brass. Never seen anything work harden as fast, or make such nasty
sharp chips that never break off and just make a brillo pad.

Like the folks on the internet say, as long as you don't interrupt your
cut and don't back off on cutting pressure, it's not bad at all.

The real struggle is always with parting off as everythings wants to slip
out of square on the tiny lathe. I measured the thicknes of the chip that
came off with a HSS parting blade at 0.005 when things we running OK.

I cut with "relion" cutting fluid, and got a little smoke as Ti gets hot
when cutting as it's apparently a bad conductor of heat.

The stuff takes a decent finish and cleans up real nice with fine
sandpaper if you're real forceful.

Can't wait to try to cut some threads on it.

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! <G>

It's 'real', just not _desireable_.

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

[Ed Huntress]

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.

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.

I used to service the machines that made the Taig machines (very
similar) out in Aridzona.
So Im more than a bit familiar with both of them. All things
said..not a bad "marginally better than a toy" machine. The factory
was fascinating in the late 90s. Everything was running off a
military surplus generator out in the side yard. Not a lot of AC
either..easy 110F in the shop during the summer months.

Shaublin small machines are hardly toys. Minatures perhaps....

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.

>Too many machine tools in the way.

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?

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

[rangerssuck]

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.

A Sherline is a good start and AFAIK does what it is meant to. However
when you bang up against its limitations it's time to think about a
larger machine instead of fighting its inherent weakness.

Unfortunately I don't know of a better currently available hobbyist
lathe to step up to. I bought old American iron with its problems of
scarcity, wear and abuse. My first lathe, a 6" Sears/AA, was NOT a
good choice due to its easily bent 1/2"-20 spindle nose.

I have a 1938 Bridgeport round-ram that I converted to CNC. I make parts
that are exported all over, as well as sold domestically. One of my major
customers is L. S. Starrett, they use my servo amps in their high-end Force
Measurement Systems. I don't even want to KNOW how much they get for those!
(The part I make for those servo amps is a mounting bracket, machined 1/8"
aluminum, bent and then rigid drill-tapped on the Bridgeport.)
The rest of the servo amp is a printed circuit.
