Brand New LittleMachineShop Lathe Owner

[Doozer]

Running a Seig C4 would make me feel like
asking for a ride from an 70 year old hooker, driving a Yugo.
Just dirty all over. Just no fun at all. But hey, I gotta be me.

It does not need a quick change box!!! READ the spec's above this is a first class machine with bells and whistles included.

Boy I was wrong it thought it had it built in the gearbox below. But how often do you thread, I have once in 20 years and feed speed more or less leave it alone on my Grizzley 9x20 but it does have a gearbox,

[Doozer]

You have cut threads once in 20 years ?
You hold him down and I will tear up his man card.
LOL
Threading on the lathe is so satisfying.
More pleasure than eating a quart of chocolate ice cream.
I ain't kidding you.

I worked at a manufacturing place where in house machine shop did no external threading on the manual machines. The one CNC lathe did whatever parts that needed threads.

A good thread, straight from the tool, with no messing about is almost as satisfying as a bowl of strawberry
ice cream----- and the thrill of success lasts much longer !

Sorry guys I have a lot of dies....

[David Powell]

Tailstock die holders can save a lot of time. I routinely single point to about 70% of thread depth then run a tailstock die holder to give the final thread form and size. BA threads, found in many models are not easy to set up, even if you have a large pile of changewheels so I normally just use tailstock die holders,

Well, yes, certainly! What I thought might be confusing him was having a two-speed motor.

A 20 speed motor will not effect the "feed rate" when using IPM or IPR.

020" IPR will feed at exactly that at all spindle speeds, it is gear driven or control driven.

IPM feed rates are independent of spindle speed "Inches Per Minute" is exactly what it says, the tool moves at X inches per minute even if the spindle is at 0 RPM's.

MMR is drastically effected by the spindle speed and feed rate.

Some of you folks are screwing up. Arguing (yeah, you went off the rails again)>

The Goal? Introduce new folks so as to keep the hobby alive?

As a new guy, trying to do some home shop machining you guys make it sound like a foot race or competition.

That will keep the new members away. They dont want to see that. They dont want to be a part of that. JR

Yeah, and making people who have been here a while to wonder about this place.

Let’s get this back on track for him. Jammer Six, what did you do or how did you determine that there was only 2 speeds for the power feed?

Is there a chart either on the lathe or in some paper work that gives you what gears give you what thread pitches? Does that one or is there another one that has anything expressed in decimals? That would be your feed advanced in either inches (or millimeters) per revolution.

[Richard P Wilson]

I strongly suspect that he engaged the half nuts, got one feed rate, then tried the power feed and got another, slower rate, without realising that he has to change gears under the end cover to vary feeds.

FYI the Sieg C4 that LMS sells is not the run of the mill cheap ones that Harbor Freight and others pass off. They are marked at the factory with the LMS serial number on the bed. When I got mine years ago it was like a breath of fresh air. I had purchased and sent back two others that were a POS from other sources. The LMS one ran out of the box and zero issues, finally sold to get the Grizzly 9x20 I have now.

Yes I did the get the old 1943 South Bend Heavy 10 and put another $1000 into it and then sold at a great loss thing. Oh it only had one feed screw also...

This!

[reggie_obe]

This!

No!
Introduce and keep someone is the hobby?
The right way would be ask questions first and guide the new person into an informed choice
The opposite of I've bought X and I can't get it t do what I want, no manual,etc. Now what??
