Lathes '93, '94, '97/8, 2001. Baruffaldi and Sauter electric turrets. VMC mid 90's.

This topic would have been more suited for the General thread.

Not sure what your problem is with Therm and really don't care. This site is not the place to bring your personal problems to. You are right, PM has a serious problem and Don needs to get a handle on it soon. Ten years ago this would have been nipped on day one.

This sight is monetary driven and this is absolutely disrespectful to Don and quite frankly the rest of us here that prefer to work with one another. With each attack you post it is just an attack on your personal character. What exactly are you trying to gain?

dude was a bit rough, but i do feel where he's coming from. maybe its the fact that english is my 3rd language, but most times it is very difficult for me to understand thermite's ramblings... oh well.

All our turning centers have air-powered parts catchers except those only used for 2nd ops, and they all have blowguns.
But I can sure remember when the extra cost of extending the air lines factored directly into my paycheck. And that definitely qualifies the thread for inclusion in the Shop Owners forum.

Mori Duraturn 25XX is Hydraulic turret lift, Hydraulic turret index, hydraulic chuck open/close, electric lube
Mori Duraturn 20xx Hydraulic lift, servo index, hydro chuck, electric lube
Those don't have a single air connection on them

Mori NL - Hydro lift ( actually it's a zero-lift so hydro unlock ), servo index, hydro chuck ( main and sub ), electric lube
It does have an air connection, but only for part eject on the sub, chip blow on main and sub and parts catcher up/down.
If you have no air, just jumper the pressure sensor and the machine isn't the wiser.

Haas SL series: Pneumatic turret lock/lift, so right outta the gate it does need air.

More of a no repair no hassle warranty.
Comes with the cheap disposable commodity mentality. And I get it. But there is lots of money to be saved buying used. I'm an 1984. So melennial but barely? I like used!

Unfortunatly I live in a norther smaller town, so used on neiche items is hard to come by. Working from a home garage shop my needs are neiche.
Needs to be as low draw as possible, but quality. Commodity items have killed this bracket imo.

Being "remote" most warrenty centres are 550km away. So even if it's warranty I have to pay a small
Fortune for the drive to and from, plus hotels and meal sub. It's a killer.
Do that a few times and it's the cost of a new kaiser air tower all over again..

As a millennial who loves vintage equipment, I think it comes down to something i noticed with my boss. He would rather spend the money on a new one than waste time trying to diagnose and fix our current one/a new one if needed. Just today I was boring out a hard emegency collet. He said "dont waste time, just go spend the 35 bucks for a new one."

A lot comes down to just not dealing with the hassel.

Hum.....well if you were boring out a "hard" "emergency" collet, that might explain a lot right there....

Some see hard, different than others, that is why there are "blue pills"

Every lathe that I have ever used has been purely hydraulic, no air at all. Some Sauter turrets are purely electric and don't even need hydraulics.
