Re: 13" Southbend with taper lock spindle in Maryland
??? ??? That's a nice hunk of lathe for that kind of $$$ . Didn't
the 13 all come with taper attachments of did that start with the
14" lathes ? I wish my 9" came with the leveling feet . I made
mine .

My South Bend search on ebay yielded this.
Great price and a step up from the 10's. (I have a 13" with D1-4

Some belt slippage is good? it can prevent a hard crash . How
much slip , well that is different for each machine . I can't give
any input on the link belt as I am running a V-belt that my
machine came with? . If yer belt adjustments are all good you
should be able to take a depth cut that corresponds to to the
chart ya got on Ebay . Sounds like maybe ya should come up with
some kind of shield to keep the drive unit clean of oil ? I don't
have a problem with oil on my drive setup .? Can't say anything
about the question of the channel flexing , we don';t know what
kind of channel yer using .

I
have a simple question. How deep of cuts
do you normally make?
I have a 1949 vintage SB9C, with 6
speeds. I replaced the 1/4 hp motor with
a 1/2 HP one. I use carbide a lot, but
HSS still gets used some. Many of the
videos say I should take at least a
0.005" cut for the best finish. I
usually cannot take more than 0.002"
with dragging down, or stopping, the
spindle.
What's reasonable for me?

Link belts stretch terribly, both long term and elastically. ?Also, depending on type, if the V pulleys or belt are significantly worn on the cheeks, the rivets can bottom out on the grooves of the pulleys, which pretty well eliminates the friction necessary for power transmission. ?Use an endless V belt. ?It is only worth using link belts either if you can double them up where doubling would not otherwise be necessary, or you have a big movement on the belt tensioner, preferably with self adjustment e.g. by the weight of the motor hanging on it. ?

Re: Probably not a good thing
They haven't made quality products in decades.? Some of the stuff I have seen was laughably bad.? Last time I bought a bore gage from them it was still made in the USA and finally I accepted the third one.? A shop bought a full set of around 6 bore gages and all were bad out of the box.

Re: What is reasonable asking price for a 1961 heavy 10
It’s all back together and I have it running now. The previous owner had put it back together and had been using it since he primed it. Some parts still have original paint.?
turns out it comes with two motors- a single phase that is attached and running and a three phase that is resting on a platform. The forward reverse is wired to 3 phase and the single phase is wired to a regular on/off light switch. Had thought light switch went to work light attached to carriage.
It has the newer double tumbler gear box.?
judging by the ways it has low to modest wear.?
had to dig out the lathe from behind my siding brake to get at it from the front.?
I’ll probably throw it on marketplace for $2500 and see if I get any action.

Re: What is reasonable asking price for a 1961 heavy 10
"Previous owner had stripped it all down and primed the lathe but not painted it."
The details there are going to make a *huge* difference.? Is it disassembled? Was it stripped and primed without taking it apart? Was it assembled?after priming, but needs taken apart and painted again? Are the machined surfaces/bolt holes masked still? etc...
Let's assume it's painted, assembled, and can be demonstrated working without significant wear (E.g. you can turn a ~6" bar to within a few tenths pretty much "as-is").
If it has a quick-change gear box, then you'd probably be able to get $2000-$3000 in the Pacific Northwest, if you're somewhat patient. You'll have to adjust for your location.? At $1500 it would probably sell in a day out here.
If it does *not* have the gearbox, then $1500-$2k, but might take a few weeks to find a buyer.
If it's in need of a complete?overhaul to get it actually painted properly, then you should probably do that before you consider selling it.
--Rogan
My son picked up a Southbend Heavy 10 serial number 12446RKL16. Near as I can tell it is a 1961 Heavy 10. It has the lever action collet closer on the head stock, taper attachment, and an aftermarket quick change tool post with a few tool holders. It has both a 3 and a 4 jaw chuck and a faceplate and a drive plate. On lathe dog and a handful of 5c collets. It appears to have a 3 phase motor. It’s on an original south bend cabinet. It does have original lantern tool post or at least parts of it.
Previous owner had stripped it all down and primed the lathe but not painted it. I’m still in process of cleaning it up a bit after sitting in my unheated shop this past winter.
Located in central Virginia.
I haven’t really been paying attention to prices for a while.
I know the one answer being whatever a buyer is willing to pay but that doesn’t really help set a fair asking price.
He needs to partially fund a newer heavier lathe that is more in line with what he needs for his job shop. He’s holding my SouthBend Fourteen hostage ?until he gets something else.

Re: What is reasonable asking price for a 1961 heavy 10
If ya have it apart I'd replace all the felts . That's something a buyer
that knows about these machine would ask about . As far as a price , I'd
spend some time on FB & CL for yer area to get some sort of idea of its
value . That 3 phase motor may be a deal breaker for alot of buyers .
What other tooling does it have ? Chucks ?

Re: Indexable carbide insert turning tools
BTW.? Double check my thread depths.? Initially the nut didn’t fit.? In hindsight I should have done the shaft first and then used it to test the nut threads increasing thread depth in the nut until the shaft screwed on easily.? ? If it’s done the other way around it’s really hard to realign the internal boring threading tool with the existing threads since they start from the headstock end and move to the tailstock.? Can’t see anything to line them up.? Plus holding the nut on the shaft for periodic testing is clumsy.? ? Don’t ask me how I know. John ?

to drive carbide tooling, but I'm considering a
switch to an Enco 3.5" turret. I can still use
my 1/4" HSS in mild steel holders, but plan to
step up to 1/2" HSS, at least until I get enough
practice in to warrant spending the ducats on
something better.

Re: Indexable carbide insert turning tools
My Southbend 10L got some use over the last week creating a slitting saw arbour for saws with a 1” hole.? LH threaded arbour and nut.? Nut was held in 3-Jaw and threaded internally from left to right using my ELS. Really like having the QCTP for a project like this.? It was turned between centers to avoid issues with mounting and unmounting for test fitting the saw blade for example. ? John ? ?

Subject: Re: [SouthBendLathe] Indexable carbide insert turning tools? That's the one.? :)? First thing I put? QCTP on was my Atlas, since the the rocker was missing when I got it. So I made a rocker, and bought it an AXA-clone. My first lathe was a 7x10 mini-lathe from Harbor Freight. It had the tool block. I eventually got it a QCTP, as well.? I'd been having problems with the mini-lathe, and moaned about it to my wife one day. She told me to take another class. At the time it had been about 41 years since I'd taken my first class. In that class, I learned that it wasn't the lathe that was the problem, but the operator. But I did get a bunch of experience of QCTPs on the class lathes. They had a 13", and a dozen or so 15" Clausing Colchester lathes. I mostly used the 13" lathe because it was closest to what I had at home. Not real close...? I'd also spent a lot of time reading everything? I could lay hands on about machining. Takes practice to put it all together, but I spent over 7 years? in that class, a couple times a week. Eventually I got to the point the instructor said I was turning into a good machinist. I did some projects of my own, as well as their stuff. Had a lot of fun at it. I'd started building a small (and small machine) workshop in my back porch. That's gotten interrupted several times. Back at cleaning it up and sorting out useless junk so I can get to the machines. Not for the first time, either. Got a hydraulic press & blasting cabinet recently to help with machine repair and restoration. Once they're set up, will be working on my Heavy 10L. Press came in handy working on my old pickup this past week, too. Can't wait until I can get the big (relative to my other machines) lathe working! William R. Meyers, MSgt, USAF(Ret.)

Physics doesn't care about your schedule.
The only reason I know anything is because I've done it wrong enough times to START to know better. Expect in one hand, expectorate in the other. See which one gets full first. ? On Thursday, March 7, 2024 at 08:27:21 PM CST, Nick via groups.io <n9viw@...> wrote: Bill,
