Re: New to me Cazeneuve HBX 360 Lathe

Very impressive and that's the first hydraulic powered turret I've ever seen in operation Patio.

Re: Cutting oil holder

Now that's a really clever idea John and one I'm going to be borrowing. Thanks. Should be simple to machine a bit of aluminum into the same tee slot size for attaching that holder somewhere around or on other machines as well since no real strength is needed.

Re: Progressing From The Dark Ages.

I've found some extruded aluminum alloys aren't really designed to be machinable at all. They tear more than cut. I thought I'd scored a bunch of old but free 1/2" aluminum shafts one time until I chucked one up in the lathe. Nothing I tried for speeds, feeds, cutting tools or cutting lube would get...

Re: NEWLY-ACQUIRED JET 1236PS

Congrats on the new lathe. Just my opinion, but If that lathe weighs around what the new Jets of that size do then they show a fully assembled net weight of 1210 lbs, I'd guess removing everything you've listed would get it down to around 800 - 850 lbs. Without some type of force multiplier your not...

Re: Has anyone built a guide for a center drill.

At one time there was a tool with an internal cone shape meant to do this type of job on a variety of shaft sizes. While I've not ever used that tool I suspect it's exact accuracy wasn't that good and having an already burr free and flat face 90 degrees to the shaft's length would be needed to get t...

Re: Enco Lathe - Extended gib and tail stock clamp

So far no one has answered your second question about that tail stock clamp. These are one of the parts that are generally out of sight so some of the manufactures do a less than decent job on the design and finishing. In use I'd bet that not only is the surface finish not helping, but the part is b...

Re: Split Cotters

There used on most lathe tail stocks, mill spindles etc to clamp them at a set position. Basically two short sections of rod radiused to fit the shaft or quill being clamped with the lower one threaded. The hole they fit in very slightly bisects the shaft or quill bore. In use the two radiused piece...

Re: Split Cotters

Afaik those split cotters haven't fallen out of favor, at least not yet. Cheaper equipment like off shore drill presses might now split the casting and use a rudimentary threaded shaft and lever instead to tighten the casting against the column. Today I think there mostly used where you don't want a...

Re: Building a bed turret

So far I've never used a turret RSG but have thought a few times about picking up the drawings from Downriver Tools. Like yourself they wouldn't directly apply to my lathe so at least some re-design would be required. That's why I'll be very much glued to this thread. :-) Randy Richard on YT has sho...

Re: Mitutoyo mechanical digital micrometer mechanism stiff

The best product I've personally used for cleaning fine mechanisms is CRC electrical contact cleaner.It's formulated to dissolve and flush out old lubrication but still be safe around most paints and plastics. And it quickly evaporates leaving no residue behind. In general metrology equipment requir...
