Lathe question
Ivan Vegvary
the replies.
Have a 13" LeBlonde lathe. 1947 vintage. 1 HP, 3 phase. Running it on
true 3 phase power. Maximum RPM is 500. Would like to get it up over a
1000 RPM. Bought a VFD from Iggy, so that will get me partly to my goal.
Additionally I want to build a jack shaft pulley arrangement to increase the
speed.
What limitations are there? Lubrication is simply splash in the gearbox
along with manual lube of the quick change mechanism. Since this is my
first lathe (10 years ago) my attachment is more emotional than anything
else. Simpler would be to buy one of the Grizzly or HF 9"x20 lathes when
they go on sale. ($700 was the last sale price).
My major gripe about the lathe is poor finish and unable to use carbide (too
slow) tooling. It would also be nice to be able to polish at faster speeds.
Any ideas, discouragements, encouragements etc. gladly accepted.

No Chinese lathe will come close to the performance of the LaBlonde. Fix it.

Cringe..you may..may be able to double your output RPMs from the
VFD..which will get you up to 1000 rpm..but you didnt mention if it has
plain bearings or ball bearings. Frankly Ivan..Id sell it to another
beginner and find yourself a REAL lathe more to your needs. There are
a shitload of Real lathes available these days all over the place for
less than a grand.
Want me to find you one? Shipping would be from California.

"IMHO, some people here give Jeff far more attention than he deserves,
but obviously craves. The most appropriate response, and perhaps the
cruelest, IMO, is to simply killfile and ignore him. An alternative, if
you must, would be to post the same standard reply to his every post,
listing the manifold reasons why he ought to be ignored. Just my $0.02
worth."

What sort of lathe would you think of as a real lathe?
I am also beginning to look around for something that is not worn.

You simply cannot beat the Monarch 10EE if the 12"x20" is large enough to
meet your needs. Ones that need a new drive go for a song right now. A three
phase motor and a VFD puts you back in bidness.
For larger lathes, I'm partial to the Leblond servo shift. I'm watching for
a cherry one with taper,DRO and a full set of chucks.

What is the maxium size you would forsee yourself needing, now and in
the future? And how much room do you have, along with how much power do
you have available?
Answer those..and Ill give you some ideas

On some reflection..Ill give you a quick heads up on MY lathes and what
Ive found to be useful.
Ive got a Hardinge HLV-H...the Hardinge toolroom lathe
http://www.lathes.co.uk/hardinge/
"The HLV-H has been copied by several Taiwan firms including Feeler,
Sharp, ProMach, Barer (model CTL-618EVS and others) and Cyclematic. In
addition some of these makers have supplied machines with "alternate"
branding for distribution by dealers world-wide. Feeler was the brand
name used by the "Fair Friend Company Limited", originally of 11/F No.
665, Tun-Hwa South Road, Taipei, Taiwan with a factory at No. 805,
Chung-Shan Road, Shen-Kang Shiang, Taichung-Hsien, Taiwan. Sharp's copy
was beautifully-made and sold as standard with a hardened bed and 5 h.p.
Japanese Yaskawa drive; however, they also offered the "Acra", a less
well finished model with a soft bed and minor changes to cut production
costs. "
Its a 11x18 lathe. Fully capable of nearly any/everything you will
likely ever do. Threads standard AND metric to 11 tpi. Other threads if
you get external gears. As I recall..they cut 27 threads with stock
gearing.
http://www.lathes.co.uk/hardinge/page4.html
Hardinge TFB
This is basically the same as the HLV-H..but does NOT do threading. I
have an older unit with the narrow 5" way. Its probably the most
accurate lathe Ive ever used.
Clausing 1500 (1501)
http://www.listal.com/video/100441707
Its a big heavy duty lathe, but nowhere near as heavy as a Monarch etc
etc. It does good duty for me. I dont use it very much. Shrug..but when
I need it..its handy as hell. 14 1/2" x 52", turns up to 2000 rpm. 7hp
motor. I use a 8hp VFD to run it, because my 5hp rotary phase converter
barely starts it up in High Range (direct drive).
Ill be using it this afternoon to make up some adapters to convert Chevy
Luv hubs to hold Porsch wheels, out of 3/4" plate.
The Hardinge HLV-H, up until the last year or two, would sell used for
between $7-15,000. Today..they are running between $3k and 6k.\
Hardinge still sells them new....$60,000
The TFB until this year, sold for between $3-7k. Now you can find em for
$2-4k.
The Clausing 1500...was a $7k lathe until recently (new was $18,000) but
now you can find em, for $3-5k
Now you and I both know you can find em cheaper. We are both scroungers
of the first squad.
But the Hardinges are the cream of the crop if in good condition. The
Clausing is middle of the road quality but for the money..its really
hard to beat.
Ive found that most..99% of my turning is very doable on the Hardinges.
I seldom do anything longer than 18" that cant to into the spindle bore.
They both are set up to do 5C chuck work, so if you find one..make sure
you get the collet closer. Lots of accessories are available as well.
They used to cost an arm, a leg, and your first born child..but are
getting much cheaper and are often tossed in when you find the lathe.
If you find a taper attachment...give me a shout! They are much harder
to find..and are worth their weight in gold.
Shrug...hope that helps a little

An excellent lathe. And putting in a new motor and VFD is the ticket.
Id love to have one if I could find one here on the West coast..but they
seem far far more available in the East and Midwest.

The LeBlond Dual Drive is one of my favorites.

13-16 by 30-40 inches would be my range of size.
Power wise, anything up to 7.5 HP is fine as well.
I want a lathe with little wear.

I have once had a Hardinge HC (bought and sold), it is the same size
lathe, and I would say it is too small for me.

Not the same size at all. It only looks the same based on what you are

But I read your requirements and Ill see what I can find for you.

Gunner, I drive to Northern Calif. (S.F. east Bay) at least 3-4 times a year
(from Oregon). I believe you are only another 5-6 hours away so this would
be doable.

13-15" swing? 48" length of work?
Hummm..that Clausing 1500 I have would be a good machine type to look
for.

incredibly well, and have a 2.25" spindle through hole. The later ones
(something newer than about 1968) have an 80-speed QC box and separate
feed shaft and leadscrew. Totally awesome at 3000 - 3500 Lbs. The
standard model will do 45 - 1250 RPM, the high-speed option (basically a
2-speed motor) will do 45 - 2500 RPM. The idea of an 8" chuck spinning
at 2500 RPM makes me cringe. The listed length between centers is 42"
but the tailstock is so huge that it should be able to do 48" easily
with the tailstock hanging a couple inches over the edge.
Wear is not instantly obvious, as the carriage wipes over the entire bed
way, so it doesn't leave a detectable ridge.

Yes, I agree that those Sheldons are good. I did lose a bid on a
Republic Lagun recently.

A good lathe indeed. However..that way wear can be/is an issue.
