Re: Preparing Machines for Moving

Real Bridgeports as one example of that tapped lifting hole Harold mentioned that are in the ram are afaik rated for a safe full machine lift from that point. My Tai built clone has the same threaded location and came with an eye bolt already installed in it. I've never used it since the machine had...

Re: QC toolpost for Atlas 618

Hard to tell from that picture Steve, but if the screw tips aren't yet turned down to at least the threads minor diameter I'd do that before ever using it. If you don't those tips will mushroom out just from the constant use making them impossible to remove/replace without cutting them off first.

Re: QC toolpost for Atlas 618

It sounds like any QC tool post and holders are going to be expensive against what the lathes cost was. The A2Z were afaik made from aluminum anyway, so in my opinion a real poor choice of material for tool holding. Shereline makes a set that could be blocked up to work with his larger swing. But ev...

Re: 1st Post and ofc it's a "What the @%#&! is this" thread.

Unfortunately and 100% for sure with grinding accessories any rust certainly isn't superficial at all. Grinding is or should be roughly 10 times or better accuracy than the more usual forms of machining. Rust free, fresh paint and re-polished surfaces aren't a restoration if it doesn't equal or bett...

Re: 1st Post and ofc it's a "What the @%#&! is this" thread.

No tool holder of any type so it's for grinding shafts and/or cutting tool flute sharpening? between centers, and likely meant for use on a standard surface grinder. No idea of who manufactured it tho.

Re: HF central machinery 5980

If you have the lathe already then simply measuring the spindle threads O.D. and it's TPI or metric pitch isn't hard with even calipers. There's better methods, but caliper measurements should be close enough to identify what you have if it's a standard thread. The way things change with off shore m...

Re: Glass Bead Blasting Old Mill Vice

What about painting the items with a rubberized truck bed liner product Russ? Or MSC, McMaster Carr etc sell a variety of rubber sheets and the easy to get contact adhesive would be more than enough to bond it in place. In mining the conveyor shute's and just about everything in the grinding and mil...

A great tip about just snugging the banjo up Harold, I'll have to borrow that one.

Re: Taking Chinese 3 Jaw Metal Lathe chuck apart for cleaning

As you've found Jim most lathe chucks are pretty simple. Any binding while opening or closing is a sure sign they need a cleaning. I've got a mix of 3 & 4 jaw European and far east chucks. I can't say about the Chinese one's, but the instructions for my Emco's were quite specific about making sure t...

Re: Damaged chuck - a forensic investigation

Ouch, :-( It obviously takes a serious hit to do damage that sever. And any 16 x 60 lathe is going to have ample power to do so. Dropped on say a chuck jaw extended out from the body is possible, but even hardened jaws are going to show evidence of it on both the non gripping end of the chuck jaw an...

Re: Drill shank hardness

Yes your obviously correct about the reduced cross section with double ended end mills and since I've never bothered to buy any I'd forgotten about that. For the most part they still wouldn't work for me anyway. With my ER-40's as an example I have approximately 1.8" in total holding length availabl...
