    StanF South Bend 9A Rebuild Thread

    .020" droop? That would be a massive amount of wear. How did you measure that? If you swung an indicator tip inside the tail stocks MT and using the head stock to rotate it, those numbers won't even be close to correct. The reason I ask is because I got fooled by that method myself for a few...

    StanF South Bend 9A Rebuild Thread

    A piss poor paint job on that heavy 10. Somebody flipping it is my guess. Poor prep, painted parts that shouldn't be are all instant warnings to me. What else are they trying to hide or gloss over. Was it a rusted boat anchor and they made it look a bit better with abrasives etc on the ways...

    Why is HSS tool set above center

    I'd agree, plus the carbide grain structure seems to be much better or lets say more predictable as the production processes got better. That and better binding agents and probably better controlled results as we learned and understood more. But I don't really know much about carbide, so my best...

    Why is HSS tool set above center

    Yeah I guess it is MB. I still like Montana better. Nicer scenery, cleaner, better roads and even less people. 😀 And not to throw this thread OT, but a total tooling and machine tool desert where I am. And the main tool supplier here in Canaduh would be KBC Tools. There prices bear zero...

    Why is HSS tool set above center

    And my thanks about the additional information about carbide and that link. That's something new to me for sure. I did get curious and checked a few of my older machinist reference books. One that's fairly basic was written by Fred Colvin in 1941 titled Running an Engine Lathe does mention very...

    How did you do this?

    Your title needs to be descriptive for what the thread is about. The process is called rotary broaching. Lot's of videos and web information about how it works.

    What is this profile called and where might I get it?

    It would depend on your application, mechanical strength, environment etc. Cutting the radius a bit oversize and then using a mask on the pipe and pouring epoxy in with possibly damns around the perimeter to keep the epoxy in place could work? Any excess epoxy can be cut or sanded off for...

    Vacuoline 1405 source in the UK?

    Where you are, Shell or BP are probably the two most common. Fwiw, I've had pretty good luck telephoning and not emailing. Large oil companies all have on staff application experts with huge files to cross reference lube products that are no longer made to a more modern and compatible off the...

    StanF South Bend 9A Rebuild Thread

    Well cleaning the lead screw is pretty easy if you can rotate it slowly and using something powered. Your done now, but after your lathe is fully assembled and the screw starts to get loaded up with crap, find a roll of some thick string that will fit down into the thread flanks, soak it in...

    Jammed half nut cam lever

    Any slotted head screws like SB seemed to love to use? I've seem them described as as Cheeze head screws. And most of them seem to have been made using semi custom head sizes either for or by SB, and replacements can't be found today anywhere I've found. Standard screwdrivers are just about...

    Jammed half nut cam lever

    Not that I know much detailed information about your lathe, but obviously there's a mechanical issue. Possibly chips or debris inside? Like anything else mechanical, lathes aren't impervious to those maintenance requirements. Few machine tool user manuals ever mention that little detail though...

    Southbend and Hercus 9” DRO Install

    Animal is 100% right. And if those are glass scales and not the magnetic type, I'd mount the scale and reader head in the normal orientation with the slot and reader head on the bottom. Glass scales can be real easy to damage with just a scratch on the glass or screw them up with even airborne...

    M head / r8 spindle swap

    Maybe you recent guys posting and wanting more information ought to read L Vanise's post #39 instead of just reading the OP's first one that never gave any actual information then or even up to today.

    Victor 400 x 750 lathe

    If it were me, and if you weren't already planning on doing so, I think I'd make the extra effort and at least pull the table and Y axis apart on that BP. You might be surprised at how many chips you find in there. And it's then a good time to verify all the oil ports and lines are in fact open...
