Van, use a tap in a hole and your indicator to find centers.

Here's another odd ball set up, modifying piston ring grooves. Fixture was all the work. Customer wanted them wider for more easily acquired rings, they were for the 2 pc.Dykes style before, believe they were 1.5 mm went to 2 mm grooves.
Fixture holds piston close, pulling down on stops in the oil ring groove to square up piston, then indicate piston to center of cut.

I recently added a new antique to the home shop. It’s a cute little South Bend 13” x 5’ lathe from the early 60’s. Just big enough to swing a VW flywheel. Now I just have to tool it up. It was poorly repainted green at some point in its life. Previous owner mechanically restored it this year, but didn’t finish repainting it the original grey. It has all new felt wicks, lead screws, half nut, flat belt, freshly adjusted head stock bearings, etc. It has the rare option of a hardened and scraped bed, and the ways are in perfect shape. Super basic and slow by todays standards, but old South Bends with the flat belt drive and plain bronze spindle bearings can do some smooth work.

That is way newer than my South Bend! I have a drawer full of gears for the feed screw speed but the 1/2 nut threads are paper thin so I have not used them yet. I think someone converted mine to V belt drive at some point. It's an 8" x 33" machine and I wish it was bigger!

It’s old enough (1961-1962?) to still have the 2-1/4” x 8 TPI threaded spindle… not ideal, but it works.

It came with a Bison 3 jaw chuck and a face plate. I will need to get a 4 jaw chuck so that I can swap parts end for end without loosing concentricity.

I would also love a 5C collet set and the accessories to run 5C in the spindle. That would be great for making pushrods, rocker shafts, etc.

One thing I plan on testing are custom waisted shank head studs. The stock T4 head studs are class 12.9 (stamped on the head side end), m12x1.5 in the case, M10x1.5 in the head, and have a 7mm diameter shank. I would like to try making some shorter studs with an 8mm shank, and see how they pull test. McMaster has class 12.9 M10x1.5 threaded rod. I could turn down the thread in the center to create the waisted shank, and then polish it. Then all is needed is to chase the m12x1.5 hole in the case with an m10x1.5 STI TAP, and instal an insert. Then I can easy run shorter cylinders without running out of thread on the head end.

If you dont mind me asking, how much does a mill and lathe like that run?

I have a SB13, 1959 vintage. I don’t think the threaded spindle is that big of a deal. How often do you run backwards?

I have a 5C for it, and I like using it as much as possible. I also made an ER40 collet chuck for it, which works well for the in between sizes, as I don’t have all the 5C collets for the rarely used sizes.

Nowadays, 3 phase power is a non issue, as VFD’s are reliable, fairly inexpensive, and provide total motor control.

Here are my ER collet chucks, the big one fits the SB13, the smaller my SB9A.

/this is turning into machinetool porn - I love it!

If you are lucky enough to find machines fully tooled and sold like that - grab them fast.

I keep all my toolings - took me years to collect them. Makes it easy to buy machines and not worry about tooling them.

Also - I build my own phase-converters - all rotary. True 3-phase powered machines will reverse if you want them too at full speed. But not if you got them static types power.

That is the beauty of 3-phase power.

I am trying to get this home -

This lathe looks very similar to the one I learned on in Highschool.
I cannot remember the brand, too many years, too many beers since those days, way back when.

I did make some useful tools with it. A die stock, a Husqvarna case splitter, as a couple examples.
I wish I still had those, made by me tools. They worked very well!

Thosed smaller ones are more expensive than the really big gigantic ones. Not everyone can bring home a 10,000 lb behemoth. But those 1000-pounders you can put on your back and bring it home.
