Setting-up the PM 1236-T Lathe

I don’t maybe somebody who has experience in this area can give some good ideas...
 
Emco recommends a gear oil change every 500 hours of use. The first oil change usually looks like that because all the crap that remains from manufacturing is still in there. The oil should stay cleaner for much longer this time.
 
My local distributor sells a compaible gear head lathe, and recommends first change after 100 hours of use or sooner, with changes every year of 500 hours thereafter.

Mikey and Dabbler, thank you, that is very helpful. I was a little concerned about the appearance of the oil, a bit like liquid graphite at the bottom of the headstock, but all else looked great.

I don't have an hour meter on my lathe. Changed oil after the first couple of months of intermittent use. It still looked like new. I had opened the headstock gear case when I got it to check for crap. (I've heard all the horror stories about casting sand etc.) It was very clean, no oil either. The other two cases had oil. According to the manual you should change oil every year. Since I'm a hobbyist it would take a long time for me to match one year of production use. The oil still looks like new after two years. The gear case that drives the feed shafts had a leak. I took it apart to replace the gasket, so it got changed. What a PIA it was to get back together. My manual recommends Mobil DTE Heavy Medium for all cases and the ways. Cost was $83 for 5 gallons locally. I ordered the lathe 6/26/16, $6999. Came with Steady & follow rests, 6" 3 jaw, 8" 4 jaw, 12" face plate, drill chuck, wedge QC with 5 holders, foot brake (works well,) coolant system, Easson DRO installed, Leveling pads, light. Got these options: Taper attachment $495, 5C adjustable collet chuck w/D-4 back plate (very nice) $299, 35pc. 5C collet set (.0005 TIR) $140. $160 discount on all for paying by check. It took until October to get it. It came with a MT4 keyed chuck but the lathe has a MT3 tailstock. Matt sent me a very nice keyless chuck to replace it.
I checked the current price $7773 but doesn't have the DRO or drill chuck ($650 & 80) so it has gone up $1504 in 2 1/2 years.

Makes sense, my Corvette Z06 came with oil change at 500 miles....
 
Larry42 and Firstgear, looks like you both are driving deluxe machines although Firstgear’s look like it is more fun.

With my might light use, I think a reasonable approach would be to change the oil every few years unless I see in the site gauge that it is getting dirty.

Thanks guys!

That was my wife and I last September running in the 105 mph class at the Silver State Classic run in Nevada. They close off 90 miles of two lane highway and your goal is to average your class speed over the 90 miles. Our target time was about 51 minutes and 25.714 seconds. We won our class, we were slow by 0.0373 seconds. She has two stop watches and every mile tells me if we are fast or slow and by how much. With a half mile to go she figured we were 0.100 seconds slow, so By the time everything computed in my head, I pushed the speed up to 118 mph.

We trailered the car from Ohio, 5,000 miles round trip. My Corvette is a 2015 Z06 with some mods, it has 620hp and 635 ft-lbs at the rear wheels. The record run over the 90 miles was in the unlimited class and that car averaged 217mph with a top speed of 242 mph. That was done by a repurposed NASCAR car.

The event has very rigid safety requirements. Driver and navigator have to have approved racing helmets, gloves, shoes and minimum cotton suit. On the back of your helmet you have to have your blood type. Your car goes through an inspection and tires can be no older than 5 years and rated for the speed you are running. Additionally before you run, when you are in the queue, there are four tire inspectors with knee pads that as you roll your car slowly forward they look for a nail or anything in your tire. If they find something you have two options. Leave it in and you can’t run. You can have them pull it but if the tire leaks air you can’t run. Considering you have about $1,000 in event fees never mind getting the car there and home along with hotel and food.

There have been people killed in the event before and they are very serious about the requirements you and your car have to meet.
