    It is really a Colchester lathe, made in the UK and marketed in the USA under the Clausing name. Colchester is a part of the 600 group, and was one of the largest makers of lathes in the world at one...

    Don't know about Deckel table dollies, but I think Thiel had one for their mills. As I recall it was a tubular steel design with casters. I have never seen one in real life, so probably rare.

    Make a spring loaded jig to hold the stamps in a repeatable and square position, then lightly grind the sides of the stamp shank to bring them closer to a common alignment. I have done this for dial...

    I agree that a magnet might be a bit risky. They tend to fracture with abrasive bits coming off, so I would be a bit wary of damage to the morse taper. The flat ejector tool I mentioned does work and...

    I have a 1024 not a model A, but I think the tailstock situation is similar. Mine will eject drills or any other tooling that has a tang. It will not eject morse taper tooling without a tang. I don't...

    Just for clarification; Newall scales are not noticeably magnetic and my scales do not attract or hold chips of any size. They do operate on an inductive basis but that is not the same as the scale...

    I think another big plus for Newall is the ease of fitting. For short Microsyn scales a single end fitting is fine - I have one like this on a lathe cross slide. They are not just resistant to...

    Thanks for that. I should have thought of Grace's Guide. I knew about Dundas from the Science Museum photo and notes. Laying out holes for riveted aircraft parts is a possible application that would...

    Yes- I think this is exactly what the makers had in mind. Whether it was successful in sales terms I don't know for sure, but I doubt it. I have never seen another which may point to it being an...

    Vernijigger

    I thought you might be interested in this unusual old tool. It is a Vernijigger from the early 1950s and was used as a way of locating drilled holes reasonably accurately where the cost of a full...

    Ok - the new photos are helpful.

    The LM2940CT is a voltage regulator, responsible for providing one of the stable accurate voltages required by the DRO. It is possible that this was damaged when...

    I think awake is correct about the diode bridge, the smoothing capacitors and the voltage regulator. The thing circled in red could possibly be something like a MOSFET, but it is impossible to read...

    Butler shapers are excellent machines, but the one in the photo might be missing a few important parts. I think there should be a support plate for the front of the table - very important in keeping...

    If it helps, I run my Thiel 159 which is a very similar size to an FP2 on a 3hp motor and I have never felt that I needed more power. Both are really toolroom mills, not production mills so...

    The 10hp VFD will certainly work, but the cost will be significantly greater than a 3hp model. If you are replacing the motor anyway and you want to keep the total costs down, you might consider a...

    I believe ballen is quite correct, although you should get away with very small variations in Hz. I again guess that reducing the frequency output from the VFD will cause more problems for the...

    That is a good question to which I would also like an answer.

    My guess is that it would work OK with a modern VFD, but there would probably be a problem with running in sensorless vector mode....

    In UK at least, motor rewinds for 3hp motors are typically 'not economically viable', meaning that it is cheaper to just buy a new motor. Rewinds are still economically viable where you have a...

    Dog clutch leadscrews are a very handy feature, however the S&B 1024 doesn't have one. It does of course have a lever that selects between screwcutting and normal feeds - just like most lathes.

    I'm not entirely clear about the problem you now have. You say that the lead screw lever will not engage either X or Y feeds. X and Y is confusing - lathes generally have X and Z. The leadscrew lever...
