PM1340GT vs PM1440BV

Alex, my bad on the Yamaha model, I guess the YR1 is a 350cc but being a Suzuki guy I didn't keep up with all the Yamaha models but did race an RD400 in 1977 until I switch over to Suzuki to race in Open Production.

Good luck and I guess we will be on the same steep learning curve together here.

Cheers,

David.


David: I do have a nice GT500 Suzuki (last of the 500 Titan line) and an unrestored M15 Suzuki which is pretty cute! Never raced and given my skill level with a bike that's probably a GOOD thing!

Ha! Used to own a Kawasaki H1 and rode it to death going back and forth from the Marine base at 29 Palms to Parker, AZ on the Colorado river on weekends. It didn't handle curves very well, and it had a power curve like a light switch (not as bad as my H2 though...). That thing almost pitched me a couple of times. :eek:

Well at 68 years old I don't think I'll be pushing it like I would have as a kid and by the time it's restored I'll be into my 70's so more something pretty to look at rather than rip up the street!
 
Been awhile since I've posted on this but have commited on the GT1340 from Matt and also the Hitachi VFD. Mark has me convinced from what I've seen of his stuff that it's straightforward to do what I need to do to hook it up.
Now - to the next issue: I want to be ready to hook the lathe up as soon as possible when it arrives and to this end need to pull power to where I'm going to locate it and install a box for the VFD.
What size of Box, ie how much heat does it blow off, do I need ventilation in the box, heat sink (ie aluminum box). I need some guidance here to be sure I purchase the correct stuff.
And, Braking resister and the pot I need to vary the speed need to be purchased and ready to go. Any recommendations here?
I'm slowly picking up cutting tooling watching E-Bay, Amazon, Travers ads etc trying to pick up decent american made holders largely based on excellent recommendations by MKSJ.
Thanks again to everyone who's posted the help has been VERY valuable to me in my decision making process.

If you are already having conversations with Mark (mksj) you already have the ear of one of the best here. Just ask away. He will get you all sorted out. :)

Thanks Bill, I kind of figured that out, the guy is sharp and has been very helpful in my making decisions.

Yup, he's one of the best. When I can afford it, I will approach him about getting a setup done for my 1340. I managed to get mine up and running, even though it was my first experience with lathe controls and VFDs, but it is a hack job. Mark will do it up right. :)
 
Seems like a lot of us go through this decision making battle with the Asian , used, vfd , and budget dilemma.

There myself! With the 1440 I think it can do more in a sense of work with the extra two inches over the carriage, mass, and the five inches for the steady rest. Good value for sure and whole lot of lathe. The Pm 1340gt to me even though I don't own one comes across as something I could compare it to a motorcycle. You don't make a logical decision when you buy a motorcycle. It is something that stirs the soul. From what everyone has said about the pm 1340gt is it has a sweet feel to it. The engagement and disengagements look positive with no stumble. Nice screws and such. I can see someone letting time get away and a place to forget about the rest of life, like a bike. So I think that is why every ones budget seems go with the 1340gt.
The Vfd compliments it and allows the more constant torque of three phase and some bells and whistles if you want to explore.

I can ramble at times and may have gone on a bit but I'm that sucker thinking about blowing my budget. Ya! I just sold my motorcycle last week with enough cash to buy something and I am going through just what you all or most have gone through. I know I need all kinds of things and need way more money then I have to get a shop together.
OH Jeez! that pm 1236 looks like a runner too! Decisions Decisions. This is doing my head in, even got some sleeping pills last week. No joke of a lie! Can't wait just to be cutting chips again!
 
Final (maybe?) post on the set up/acquisition of my PM GT1340 lathe is the gear box lube thing. Like most I'm not real impressed with the standard set up where you squirt oil in thru a tiny hole hoping it distributes so I did a somewhat simpler version of Mark Jacobs elegant system.
Took a short piece of 1/2" copper pipe and soldered an end cap on it at one end and at the other a 90 degree elbow that goes from 1/4"NPT (which just fits in the end of the copper pipe) to a female 1/8" plastic tubing connection.
To the 1/2" copper pipe I drilled holes off center to receive 1/8" copper tube branches that distribute the oil over the gauze pad above the gear box.
I simply soldered the end cap, 1/8" tubes and the 90 degree connection to the piece of copper pipe, hooked it to the plastic tubing from the pump and it seems to work faultlessly and was VERY simple to fabricate.
