    Are these the sine wave output type of scale or TTL?

    Dangerous assumption. Although the classic Dahlander configuration is constant torque two speed motors can be made with a range of relative powers. The name plate on the UK built one fitted to my...

    As the perpetuator was an expat Brit I think a mild case of skin thinness.

    I'd not see "obsessive" used in that context as insulting. More a comment that you are maybe taking passionate about the...

    Better to fix the taper attachment.

    Then its relatively easy to set things up with a stop to limit the travel along the taper so it finishes in the right place.

    The ordinary cordless impact screwdriver will probably generate enough torque to do up a drawbar. I tried a Makita 18 volt NiCAD version on my Bridgeport drawbar. Verifying undo torque using an...

    Agreed.

    Did a couple of 14 ft and a couple of 12 ft 2" x 4" x 1/8" square tube parts on the Bridgeport about 3 years back. Around 20 - 25 holes, 1/2" diameter in both.

    Tried a number of ways...

    I have the high number set as well as the standard A & B "pair" for my Edgewick made Cinci cclone.

    Have experience with a different make but similar technology.

    #2 on service time.

    Had one that needed a regular clean up every year or two. Never seemed to be anything actually wrong and all the bits seemed to run ok by hand but it leaked after a while. My...

    Straight knurls? Not a clue.

    Don't think I've ever done a straight knurl in any shape, form or method in pushing 60 years of making chips.

    With that choice of brands for a turret mill I'd be looking most closely at TOS. By design somewhat heftier than the usual Bridgeport or clone, pretty much comparable to a Beaver really, it has the...

    Indeed.

    I'm convinced that the first tools issued to a new hire on the Smart & Brown assembly line were a big shoehorn and hefty prybar.

    Reckon standard practice was to hang the motor up in the...

    Yep. Adjust the link rod for near equal movement each side of central. Page Nineteen in my MK1 parts manual pdf gives a nice diagram of how the arms lie. Central, rest position shown I think.

    Getting back to the OPs problem.

    In the UK at least the normal "correct" solution to this sort of problem is to provide a separate feed from the utility incomer via its own "consumer unit" with...

    I'd have expected 0.800 as well. In conjunction with 1-2-3 blocks that gives you 0.1 increments from 1" to 3.8". mMybe 0.900 too to close the gap.
