PM was actually started bc of Chaski, quite a few folks didnt like how it was operated ~15 years ago so PM began. Don/Milacron is a member there and occasionally posts. The HSM bbs site and Chaski have both been around longer, HSM started naturally bc of the magazines. Even a few teenagers get along well there. There's only a few subforums where hobbyists need be careful on there, those that deal with modern machines/machining. Several of the other subforums are similar - mostly hobbyists talking antique iron and nobody cares if they ignore a few rules so long as theyre civil. He doesnt mind hobbyists, heck, the SB subforum on PM is mostly hobbyists who know little/nothing of machine operation or repair. Nah, Don (Milacron) is simply a machinist turned machine tool dealer. There is a wealth of info, and I can pretty much guarantee that any question you may have, has already been answered there.
And the lathe is still usable - maybe annoying, but usable.Įven if you don't register/post over on PM, you might do some searching on the SB forum there. It may be beyond you at this point, but in a year or so, you may be ready to tackle it. And I think it's been documented over on the SB forum of Practical Machinist. If you scratch around steve wells website,, you'll find examples of people that have done so. The way this is typically dealt with is, you cut off the threaded section, turn or purchase a new threaded section, then drill/bore/ream and slip fit the new section to the old portion which still has the gear. I'd bet that's a good portion of what you paid for the machine, though. Here's a link to Miller Machine, where $275 buys a new screw (w/gear) and a new nut: I wouldn't go in that direction, it has it's own set of perils.

Information imbedded in the serial number.Click to expand.I seem to remember that at one point, there was a casting change which may hang up the geared section. If there isn't any gear teeth cut into theīoss on the cross feed screw, you have the model C screw.Ĭan you give me the serial number? Lathes built after 1947 have their drive If your remove the saddle from the apron and turn it over, you should see the The correct cross feed screw (for models A and B) have a gear made The most common problem may be that your lathe has the wrong cross feed There is a problem with the gearing inside. If the cross feed isn't working when the clutch is tight (and turning), When the star knob is tightened, it will turn with with the gearing inside theĪpron. When the feed selector is NOT in the neutral position.
It is normal for the Half-nuts to be mechanically "locked-out" for engaging The star knob seems to want to turn and turn but not change behavior of anything. I haven't figured out the star knob and if it is doing anything or not. The level will hardly move at all and clearly not to the detent and engage. If I put the selector to cross feed, I can't engage the half nuts level. In order to use the half-nuts, the feed selector lever must be in the center It is engaged by turning clockwise and released by turning Just below the selector lever is the clutch
Lever is placed up for longitudinal feed and down for cross feed. The feed selector lever is in the center of the apron. Otherwise, the feed selector lever will be locked out. If you are going to use the power feeds, the half-nut lever must be in The same time! There is a mechanical lock-out that prevents one from The apron is the half-nut engagement lever. Of the apron is the feed selector and the lever on the right-hand end of ThereĪre two levers and a star knob on the apron. I think you are confusion the half-nuts for the clutch feed lever.

So I'm not so much asking for real solutions but more like tips on how I should go about figuring it out and fixing it.

I'm in the live steam groups.īut I have nothing in the way of manuals, so no exploded parts drawings or other guides to figuring out what isn't right inside or how to get there. So on his passing we now have it and I'm getting into using it. But he kept it clean and lubricated, only some surface rust on a 4 jaw chuck. Her father wasn't interested in doing that and kept it but didn't really use it much for anything. Her grandfather had it for some side work and was working on a 3/4" scale steam loco. The rest of the lathe (nice clean B model 1950's vintage) is very nice and seems to work just find. I'm kind of new to trying to debug mechanical things so need some clues of what to look for. Manual use of the cross feed is just fine as well as the compound feed. Normal manual and power feed works left and right just fine but if I place the selector for the power cross feed, the engage level won't move.
