Yes. I was referring to the housing labeled as EE2859 on sheet 142. I don't know what this looks like disassembled, but I don't think there is any connection to the headstock where my mystery hole is. I bent the end 2" of a piece of stiff wire at 90 degrees, and was able to sweep it across...

I am at a loss as to why that cross-hole at the front would be there, or what is threaded into it from the left. The fastener or plug is hidden behind the top of the gearbox. Since the hole almost touches the bottom of the sight-glass bore, it renders that sight glass useless and makes the rear...

After I got the sight-glass cleaned up and reinstalled, I put some oil in, and it ran into the center compartment within a couple of minutes, stopping when the oil was well below the line. I was expecting it to be a little low because the overflow hole at the rear of sight glass bore was drilled...

Here is the bushing pulled into place with my makeshift puller. At first it didn't seem to want to stay put, but after being clamped in position overnight it stayed in place.

I cut the O-ring groove. That cross-section O-ring so close to the edge of the bore didn't want to stay put, but after clamping the bushing in position overnight, the bushing set-screw seemed to hold it in fine when lightly snugged. The set-screw can't be really tight because it distorts the...

When the lathe isn't running, there doesn't appear to be any way for oil to get from the left bearing compartment to the center compartment except by leaking past the big bushing (EE-2888). I'm ignoring the overflow hole being too low as described above. That would only account for oil draining...

I took some pictures that show where the oil level in the left bearing compartment should be (1946 10ee w/3 sight-glasses). I measured 5" from the flat where the top cover attaches down to the center of the left sight-glass bore, which should be the oil level in the bearing compartment. Here is...

Rimcanyon, thanks for the details about disassembly! I do tend to over-engineer things, but I really want to fix it the first time. :) These threads mention the exact same problem (one in a round-dial with different PNs but the same layout): - In this thread Cal Haines suggested the factory...

Hi all, I have the spindle out of my 1946 10ee in order to apply sealant under the EE-2888 bushing and reinstall. Oil was leaking pretty quickly from the left bearing compartment to the center one. Many thanks to everyone who posted info here on spindle removal. I attached a photo of part of...

Viewed from above, the leading and trailing edges of the scraper on a square-dial tach bracket are symmetric and also centered front-to-rear at the side of the bracket well. It would work equally well with the drive gear turning in either direction.

I wasn't aware of that difference in the oiling (round vs. square-dial). A picture of the tach bracket I found in a 1942 round-dial manual shows it doesn't have the scraper on top of the bracket either. Without a scraper, oil carried up on the tach gear probably wouldn't get anywhere useful...

I have the spindle out of my '46 square-dial 10ee at the moment to fix leaks between compartments. One purpose of the tach idler gear is definitely to lift oil from the spindle bearing sump. The oil transfers to (or is splashed onto) the tach drive gear, and then a scraper that is part the tach...

Hi all, I have a 1946 square-dial with a non-functional tach. I removed it and think I found why it isn't working, but I'm not sure of the exact problem or what to do about it. The spindle on which the needle mounts has a pin-shaped end to the rear that pivots against something inside a small...

I have one of these that I restored and retrofitted with a VFD. It's been a few years since my last purchase from them, a replacement urethane drive belt, but the manufacturer is still around: Home. They were helpful back when I did my restoration. I can't compare to other makes, but I really...

I *am* aware that Kondia made most of the KM3 for Hurco, lol. I meant that the underside of my KM3 table looked similar to Dark's FV-1.

I have a Hurco KM3, which by appearance is based on at least similar Kondia iron. No help here with your specific question, and you've probably already checked this out, but are you certain the play is between the nut and the screw? If that is where the damage occurred, I doubt it would still...

I had about a year of work into a controls retrofit of an old Hurco KM3 mill when I discovered that the spindle had been crashed previously. I ended up sending it back to the manufacturer, Universal Engineering, for a regrind. They ground out the taper, plated it up, ground it again to size...

I've got a High-Speed Hammer Co. R-53 sensitive drill press that I rebuilt, and being able to drill PCBs was one of my main goals. You really need high speed for small carbide bits, and a garden-variety drill press is too slow and often has too much slop in the quill and bearings. Just playing...

One finishing touch: A convenient holder for the chuck key and the tools needed for swapping the Quadrill on and off. :)

I designed a 2-piece removable collar with a hinge. This pic shows the factory 1-piece collar at the top, a 3D-printed mock-up I made for test-fitting on the left, and the finished steel collar on the right. This is the collar closed. On the far side from the hinge there is a dowel pin...
