    I thought it looked like your machine has the original paint based on this and the other photos. If so, you might not have much mechanical wear. I love the finish on Aciera mills. It is like...

    As to material, check how hard the damage parts are by testing with a file. If not so hard, I would use a steel called ETD-150, which is a re-sulfurized prehardened 4140 or similar. 4140 pre-hard...

    My machines look similar to yours in the area of the Z-axis feed trips. The main differences are that my machines have socket head cap screws where yours has slotted screws, and my machines do not...

    The M head I had did not have an involute spline, nor would I have expected one in that era and application.

    Personally, I would try to find a replacement spindle or whole head. I believe a...

    6. I have attached an image I hope of the Z axis way cover which had some sort of fibrous material in there by way of a way wiper. I wondered if you know what this material may have been (in case I...

    The hammer dents on the chuck face do not inspire confidence. What do you mean by destructive testing? What got destroyed? In any event, your asking price is high by at least a factor of two, sorry...

    1. I have taken the table off to clean behind there but I wondered if there are any other components I should remove and check or clean before powering it up.

    I assume you mean the part I call the...

    The transmission sounded pretty good for its age on my laptop speakers, and I did not hear chatter indicative of spindle bearing looseness. You should check all of the other speed and feed ratios for...

    That looks more like a motor-driven compressor. I am curious about the snout off to the side of the crankcase covered by a blind flange. Was there a reciprocating engine cylinder attached there?

    Is there any branding on the bearings? Metal stamps on the crank? Are the crank journals imperial or metric?

    That's not a compressor. Why would you need mechanically-driven exhaust valves on a compressor? In addition, if not for a magneto, what is the auxiliary drive for?

    Going back to the engine, what...

    It seems to share some cylinder characteristics with Henderson motorcycle engines from the teens, but the open cam is a real puzzler.

    Ross,

    Thanks for that. It would not be hard to implement on the Acieras because the Z handwheel is at the end of a long, hefty, and separate turned housing that could accommodate a spring-loaded...

    Oddly enough, the fraternal twin Acu-Rite DRO203 has buttons.

    I feel like an idiot for buying a DRO203 and a far less capable and pleasing Fagor 20i and paying almost exactly the same price. The...

    On both of my Acieras the table continues downward once set in motion, but they don't take off on their own from rest. The friction is so low, the table weight can back-drive the leadscrew....

    My opinion is $100-$150 would be fair. It looks rather worn but not beat up. PM, rather than a thrift store, would be a good place to sell it.

    What is the circled black item for in the photo below? Horizontal quill? (It seems to be too far back from the headstock face for that, but maybe??)

    A 0.010" runout at that amount of overhang seems perfectly reasonable for a milling arbor. I bet you can change the magnitude and direction quite a bit, just by bumping it with your fist. The arbor...
