The New South Bend 10K

I was offered that lathe years ago from Pappa Grizzly himself...Bob

So why didn't you take it? You could have saved me a headache and much frustration.
Papa Grizzly should have just left this one in the tent sale. If I had known what I now know, I would not have paid more than about $2,500.00 for it. I spent at least 8 to ten hours on this the last couple of days. The new pulleys and belts arrived. ( Thank you, Mike ) After some PITA work the new pulleys are on and the speeds now appear correct within 5 to 20 RPMs. The belt tensions were off, of course. But after modifying the tension cam, ( removing about 1/8" of material ) it now functions as it should. The only real issue at this point is the motor. It just does not have the torque to develop full no load speed in the two high gears. 782 rpm and 1200 rpm. So at least things are now looking up a bit. Looking at the way the motor is mounted, I suspect I would have problems finding a replacement to fit. Hey Shiraz! How about sending me a new motor. ( One that actually works as it should ) I think if the production models have all the improvements/ corrections they are probably fairly nice lathes. A side from no back gear. I can not help but wonder why they just didn't make the 10Ks a 10-24 and the heavy 10s a 10-30. Who knows? So it looks like I am going to have to travel to Springfield Mo. to see for myself. Road trip!

Well, I must say. My faith has indeed been restored to some extent. I received word today, the tech. folks took a look at the motor issues I was having and decided it was a defective motor. No surprise there. But they are sending me a new one. So a thank you and Kudos to Papa Griz and Mike. I might actually make a couple of bucks from this lathe, yet. Projects are a waiting.

When you finally get this up and running it would be nice to see some pics.

I came very close to buying that lathe.

Me too... You go first.

I been looking and searching on local AZ (GL, Ebay etc.. )for about a year and I couldn't find any SB9 with decent bed and saddle,
99.9% are worn old machines, I paid $500 for a very worn 9A that had tail stock missing, motor, countershaft, belt, bad spindle, damage headstock etc...

till this moment I spent $1600 and still need new bed or grinding the current bed, and aligning etc... and still not running!

for grinding the bed will be looking for another $1200 and go on with the bank!

I start thinking to sale this junk and buy NEW machine with brand new hardened Bed and all new will be great to own to do precision cut and no wear to worry about!! I already have my milling attachment and I will use my collets too!

if anybody here saying south bend 9,10,11 etc are good and better I will say yes if you find a decent lathe with excellent Bed like this deal bellow:-

and please don't tell me about study rest, because not everybody need it!

Ozy

OK. SO finally I had time, or rather made the time, to switch the motors on this "sample machine". The replacement motor was different and the wiring was different than any of the diagrams. So I spent some time and more bucks completely rewiring this machine with the new motor. I haven't done anything like that for quite a few years. And Eureka! It's alive! It is now more quiet and smoother running. There will be more testing and checking down the road. But for now I am just thrilled to be able to use it at all speeds. I took a few snap shots of it. I have not replaced the tool post yet. They are still in the boxes in the drawer. And I was using some China made C6 brazed carbide I had to shim to center. But I started de-nubing some CNCd saw fasteners getting them ready for the mill. Having to step around the replacement motor sitting in the middle of the floor was a good incentive as well. Did I mention my shop is very small? I still have the lathe sitting on dollies as well. But at least it is level. So some pics. As promised. Some of the saw fasteners, by the way, seem to have a bit of a pin wheel effect. Perhaps some oscillations I was not picking up on. I will look more into that tomorrow.

Nice. Do you grease the spindle bearings?

Yes. The manual states one or two pumps each day of use. I did shame myself into going back and wire in the safety switches.

It's good to see you were able to make it to the finish line and getting a working machine. Looks like you have a decent backlog of work to give your machine a good testing.

Before you declare total victory, however, I think it would be a good idea to to cut some threads via the single point method just to prove-out the gearbox and leadscrew. Better to find out now while you are still on first-name basis with the tech support people.

Glad you have it up and running. Feel free to post more pics (maybe threading?) if you feel the urge.

If pappa griz ever decides to sell those at a decent price (half off?) I might get one to replace my 8k because it's a pain to thread on. Current projects remind me of why I want/use a smaller lathe for some things. That nonsense of making small things on a big lathe is an old wives tale IMO, and I need to make small stuff quite often.
