Re: The ultimate 3-in-1 machine

Apology's to the OP since this is a bit OT. Yeah it would Russ, but at the level those Vedder-Root (SP?) mechanical dros were made to and showing actual 10ths movement you'd need ultra high precision hardened, ground and possibly lapped gearing. The average feed screw pitch on most lathes and mills ...

Re: Electronic Leadscrew

There's also https://www.rocketronics.de/en/els/ for an already built kit version to do the same and even more. And http://www.babinmachine.com/index.php?HLVELECLEAD as a high end industrial level version for the HLV lathes. I've been following the one in your link since the first video was posted a...

Re: Ralmike's Rotary table

If I recall correctly Ralmike was only a tool dealer and not involved with the production of the tools themselves. So just like some tool suppliers today they added there own badge to that R/T. Someone else might have better information about who might have manufactured yours. It's definitely not fr...

Re: How do I know SB9 Lathe I just bought is a good one?

Do an online search for a pdf of the Dr. Georg Schlesinger book Testing Machine Tools. Read through that enough times until you fully understand what's being tested and why. The maximum allowed deviation numbers within that book would be for high quality new or fully rebuilt industrial level machine...

Re: 3 jaw chuck

If you look at the history of lathes 3 jaw scroll chucks are a fairly recent convenience but not an absolute necessity. Before 3 jaws were invented turning between centers and shorter work got bolted to the face plate using various methods. Probably it didn't take long before screw adjustable jaws w...

Re: Lamp Stand.

A couple of good examples of using spare machinist related components for what your needing. I like it. Quite awhile ago I ran across a picture on Pinterest of a couple of lathe lights made by using chrome plated chevy small block engine valve covers, AN fittings and braided line used for the cord c...

Re: South Bend 9 Original Way Roughing

That front way scraping does make at least aesthetic sense Steve since not doing it there would appear odd and the machine left unfinished. And your picture certainly shows actual scraping and not the irregular poorly done attempt at flaking in Carlos's post. I can see proper scraping being done und...

Re: South Bend 9 Original Way Roughing

Everyone doing scraping or flaking for oil retention will develop there own distinctive pattern if you know enough to recognize it. Moore Tools and possibly some European manufacturer's might be the exceptions to that though.Like Harold I'm neither a South Bend or scraper expert, but I'd be quite su...

Re: Correct Usage.

Those L/H bars are also for use in the horizontal cross holes most boring heads will have for doing bores larger than the head diameter.

Re: Help Identify Fowler Lathe part

I'm almost certain that Fowler name isn't tied to the Fowler / metrology equipment. A quick Google search did get at least this much. https://www.practicalmachinist.com/vb/antique-machinery-and-history/fowler-burbank-ca-309498/ The picture makes it appear like the bed bolted to the front of the head...
