    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.

    Have you verified that the clutch operating mechanism is in good order and correctly adjusted?

    Smart and Brown had an unfortunate habit of being occasionally over clever with the controls and...

    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.

    Far as I know there was no official model number. Everyone calls them gearbox type power feeds or, when they pull them off " 'kin heavy sucker".

    Yup they are/were around. A early form of tamper-proofin I guess.

    Couple of decades or more back I saw a small dose system working rather like the old fashioned mechanical, cam operated, petrol pumps. Set the stroke of the operating lever/cam to determine the...

    I'd be unsurprised to see that I got it wrong. Which is why I carefully wrote it all out. Those things are confusing.

    I always find it helpful to think of the threading dia s being a very coarse dial type vernier. So if the screw is stationary it measures the saddle movement along the bed. If its rotating a...

    Ram on mine was frozen when I got it. Clear evidence of it being left outside uncovered for a while, water in the head being a clue, so primary issue was probably corrosion related.

    My Bridgeport J head has to come off "soon" to investigate belt noises and power down-feed issues. To make the job easier I shall make a decent size foot with an R8 blank arbor firmly spigoted into...

    Limiting factor on stiffness in cut for a Bridgeport is the quill. With the quill locked up solid it can safely use more power but you have to pay more attention to what cutter you are using. Big...
