Re: Questions about new DRO

:-) And that's the exact one I was thinking of Dave. You did a top quality and well thought out job on that. At least my memory wasn't faulty about it being one of the best I've ever seen.

Re: Asian/Chinese made Dividing heads

Maybe start a thread Britt and I can give you some dimensions from my RT and DH. I'd rather not take Wally's OT.

Re: Asian/Chinese made Dividing heads

By Hofmann are you meaning having the ability to connect the dividing head to the mills X axis feed screw, or do geared compound indexing Wally? If so then yes there quite a difference between what's known as a plain indexing head, semi universal and a true universal dividing head. B&S made all 3 ty...

Re: Brand new old school south Bend 10” lathe!

If my memory for the numbers isn't too faulty Blue Ridge Tools would have been pricing the same lathe comparably equipped at around 14-16k in the early 80's. That's the main reason the American built South Bend company is now long gone. Sadly it seems to me that some of those collector types have mo...

Re: Brand new old school south Bend 10” lathe!

I believe that's the one with a thread about it over on the PM South Bend forum Glenn. Given the asking prices for new South Bends when they were still in business in the 1980's his asking price isn't really out of line for what it is. Some years ago about 10? brand new still in the factory crates S...

Re: GE 44 tonner

I know almost zero about locomotive building, so bearing that in mind since there track gauge is .650" apart for HO scale then to scale up to 2 1/2" you'd divide whatever gauge that uses by the .650". That should give you the multiplication factor. If it is exactly 2 1/2" then you'd multiply all the...

Re: SX3 spindle clamp

Both my lathes and the BP clone use brass for the cotters Earl. Maybe if soft steel is used it doesn't matter?

Re: SX3 spindle clamp

Yep Earls correct. Another name would be a Split Cotter. That's of course the usual North American term and other parts of the world might use something different. Since "cotter" was a common name used for various designs including wedges to semi permanently lock shafts in place on some steam engine...

Re: Rotary Broach holder

Youtube channel Randy Richard in the shop did a full build series of the Hemingway Kits rotary broach. Plus numerous other videos on YT should provide just about anything needed to build the tool or broach.

Re: Piston or Wedge

Well to add this there's also the European made 3 position Tripan tool post that supposed to be very very good, and with a price to match that's typical of high end Swiss made machine tools and tooling. They allow much better clearance in some situations. Especially when using tail stock support. St...

Re: Drilling and milling questions

Yep it's pretty amazing what supporting a cutting tool at both ends can accomplish verses having only one end in a collet on a vertical mill Rudd. Your method sounds about right though. :-)

Re: Drilling and milling questions

Almost impossible to answer with any certainty about the maximum hole size. It all depends on the machines design and rigidity. As an example, a 250 lb 1/2 hp bench top drill press couldn't drill holes with any 1/2" or larger drill half way as well as a 1/2 hp 250 lb bench top lathe could. The diffe...
