I'm told this is now sold. The new home is in a bottling plant so presumably maintenance and more prototyping.

Sorry for the duplicate answer there, but I saw the machine in person over the weekend. It is owned and was used by a professional machinist in a one-man prototyping operation for many years. If I understood correctly, they were the second owner, but the first owner didn't use it much. So...

Horizontal spindle is gear driven and those are speed selectors.

Buy him some really good pot and set him in front of a grinder with a bucket of bits. Put on some good 'ol banger 'tunes and come back in a couple hours. Job done! I quite enjoy sharpening bits if I'm in the mood for it, but for some reason it's one of those things I have to make time for...

Shoot, I just came from there back to the island!

I've been using a Darex V290 (V390) that I picked up at a yard sale for 50 bucks a few years ago. If you trace back the lineage of all these one-and-done fixture grinders you'll probably stumble on Darex, for one. I'm a semi-decent sharpen by eye -kind of guy, but for small drills, the V290 is...

One side benefit of this embarrassing fiasco -- I never understood how the `origin' button worked. I've replaced a few batteries in this unit over the years, but never touched the origin button. Every time I used it, I had to reset zero with the zero button in closed position. I just assumed...

BINGO! Very strong light behind the closed jaws revealed the problem -- the pointy ends of the jaws must have been hit in a drop event -- << looks around for the culprit >> -- a thin parallel line of light through closed jaws. After a very careful stoning of the jaws to remove the burr on...

This is an older Mitu CD6-CSX that has seen only light use. Have a job here setting shims in mechanical injectors so I wanted a quick and reliable way to measure them from stacks that I have laying around. Quick yes. Reliable, not so much. They weren't measuring to known stock thicknesses with...

Ok, I'm gonna jump in and ask the obvious question -- why would someone pay that much for a 2-axis (lathe, not milling DRO) in used condition? Was this some golden age of the DRO Pro lineup? I'm pretty sure you can buy the current DRO Pro equivalent for the same amount from them, or even less...

A good deal is in the eye of the player. Or sometimes the dealer. Post away. These days the 'spotted' forum is the most interesting part of the site for me!

I saw the lathe on Saturday morning (picking up something else from the seller). It was everything one might expect from the photos, and more because the owner had put some well thought out, high quality improvements into it. I don't recall he made a big deal about this in the ad. Is its new...

C Congratulations Dabbler!

DC motors by the look of it? Price is right!
