Heavy 10 lathe light

Joe Stefanick
 

I have my 1966 heavy 10 running with the VFD and after a few shake down cruise issues I think it may make chips.  But I need a light on it and would like to have look some what original. are there any photos or catalog images of the the way South Bend did it? My lathe has the taper attachment if that makes a difference.

Thanks, Joe

Go to eBay and look for bluechip machining 
or south bend lathe oil

He sells bottle of the correct oils for spindle, ways and general lube.

Greetings

Paul H in OKC
 

I am the proud owner of a 16 x 60 SB lathe. Have actually owned it for a couple of years, but recently got it home. Phase converter going and the lathe is pretty smooth. Will be working on the belt soon, but otherwise..... I am a machinist bytrade and always wondered about being able to do something on one of these, but am sure as I just want to be able to make stuff at home. Anyway, glad to be here. Will be looking for info thru the faqs and from others about a few things, like oils for the headstock bearing and such. Going to look up serial # to find out age and such. It is an under drive with chip pan, 3 and 4 jaw chucks, face plate and taper attachment.

Thanks!

Paul

The shaft has to rotate. There's a groove around the end of the shaft where the retainer pin goes, which is why it's offset.

If you are using the low speed set up check the gears for a metal chip in the gears

I was working with my lathe and the other day while indicating in some round stock noticed that the spindle was starting to bind in approximately 1/4 of it's rotation. This occurs in the same section of the spindle every time. I have kept the spindle lubricated while working and so i am puzzled as to what has created this situation I am in the last phase of of some work with my lathe so basically I'm at a standstill. I don't want to further any problems but I need to resolve this situation. I am going to break down the headstock for inspection but certainly would appreciate any input on diagnosing and resolving this problem. I am not familiar with the specifications for the lathe i.e. , id's and od's of the mating /matching parts. What am I looking for in this circumstance and what options might I have to get up and running making chips A.S.A.P. Thank you all.

This may sound stupid and obvious, but first make sure that you don't have the gear train engaged and a chip jammed in the spindle gear.

Hi thanks to all who have posted to help me. Well I took your advise and started to remove all the gears from the gearbox I am having trouble getting the pin out that holds the tumbler shaft with tumblers still on it. I can see what looks like the big end of the pin(even though the rebuild manual says its a straight pin) the only other thing I can see is a smaller hole that doesn't line up with the center of the shaft? Is that right does that pin not go thru the center of the shaft? The shaft does spin so I guess that's right unless the pin is broken? For the smaller hole to be the other end of the pin the pin would only sit in a groove at that end of the shaft is that the way it is?

That's what I did when I bought my lathe with a crashed gear box.  I tore it down, found the broken gear, ordered the gear from Ted and a felt set on eBay, lubed all the cleaned parts and reassembled it.  It was really, really tight after reassembly so I tore it back down, polished some score marks off the shafts, reassembled it with more lube and kept working it by turning the input shaft with a wrench until I found a chip pounded into the valley between two gear teeth.  After cleaning the chip out, the gear box works smoothly in all positions and I've been running the lathe daily for a couple of weeks.

I figured worst case, I was out a few dollars for felts and $65 for a gear. As it turned out, it was a fairly simple fix.  I'd tear it down and see what is broken/bent.   The gearbox is already broken, you probably won't break it any worse.

That's what I used fitting a 7" 4-jaw to a backplate. Harbor Freight caliper only read to the nearest half-thousandth. Got it to a nice mallet tap fit onto the chuck, then I used a transfer punch which happened to be exactly the right size in the bolt holes through the chuck to mark the plate for drilling and tapping.

Re: Anyone try a Shars fully machined backing plate and chuck?

Curt Wuollet <wideopen1@...>
 

It's a 6808 zz or rs.  7mm width. I needed to shim the bore because 40mm is a bit too large, but the next standard size is too small. It was less than $10 delivered from www.bigbearingstore.com.

Since I had the mounting solid and the motor working, I put a 3/8" Indexible carbide tool on the QCTP and set the spindle for the lowest non-backgear speed, just a bit less than 300 RPM. I set up the cross feed for about 2 seconds a revolution and faced from the inside out with the carriage locked down and
feeding with the compound. It worked splendidly, giving a nice finish and that crunchy frying sound that cast iron makes when things are about right. Since it was working well, I covered what I could and kept right on going about 20 thou on the dial which would be 10 thou a pass. Lots of passes later I stopped with the hub at .500 long. This gives me  a register bore about .200 and much better thread engagement. Took it out and cleaned the threads and turned it around sans the spacer. It wouldn't seat because there is a radius on the spindle, so I set it up again and chamfered just enough for it to seat.
I seated it, then I put the indicator on it and got about a thousondth axial runout. It was time for bed.
I intended to get at it again tonight, but I was beat after work and had some other things to do. But now I can get to the actual fitting. I'll face it enough to take out the runout and get clean metal. All I have that's that large is a cheap 6" digital caliper, so I will have to proceed very carefully.  I want to be rested and wide awake.

Hi James

I'm afraid not, it was someplace on the chain of messages on the hobby machinist site. I do recall the poster rejoicing that he found a 7mm wide bearing with a ID slightly larger than 1.5" on Ebay for $8. The source was not cited, But I expect VXB or one of the other bulk chinese bearing places would be a good place to look. I thought it a good idea as they are usually ground more accurately than my ability to measure. And hard and smooth enough to stay that way.
