    It's from the link in my post #5. I *know* only the resistance and coil size - know nothing about inductance but the calculator lets you alter that figure until you come up with a coil size, wire...

    Same thing on my Android. New a couple of weeks ago and not had any updates applied but I get this big black banner about cookies that can't be dismissed.

    If I were in your shoes I would turn a delrin spool to the dims given by 10k:



    Then use the same method I did (in my link further up in post #5) to put 23,000 turns of your 39AWG wire on it....

    There must be a good number of these tumbler reverse gears floating around because ZK makes the silent gears so the originals would have been removed.

    Winding a replacement will be no more difficult than putting a mic on the conductor of the other coil to discover it's diameter then making a delrin bobbin and winding on the wire until it's filled a...

    It was myself who had the 240v coil in my 115v machine. I had to wind a replacement coil and removed the 240v one to save for anyone who might need it. Kept it for 5 years and yet when the time came...

    I'd fit the VFD and keep an eye out for a spare. If there's insulation degradation it's bound to be a function of time and use so your lightly-used home shop mill motor will probably out-last the...

    That's nice. I wonder what is the purpose of the 'horn' cast into the end of the sliding table?

    Go back to the original RPC and ensure that it still powers the MG up correctly. If it does then check it's earthing properly and if it is then check the wiring arrangement on the bigger one.

    I use open gear lube on mine. In a pinch I would use chain lube. A single tin of open gear spray lube would probably last the lathe (or the operator) a lifetime.

    Nice. Was it you that bought the swivelling table on Homeworkshop? Fairly priced for the condition I thought.

    Yes, looking at all the pics it's virtually all there and I think the slide is connected to the pin. Looks like even the Jarno spindle adapter is present. I love the double-stacked cross slide that...

    Thanks for the catalogue link John. They list a quick-retract for threading so I expect that's exactly what the lever under the cross slide screw is. They also list plain- and elevating compound...
  18. Big old Pratt & Whitney with unidentified features

    My friend just bought this lathe and sent me some pics. It's a big old P&W about 10' long and something like 3 tons, reportedly from the early 1900's. It's in remarkable condition for such an age and...

    Thanks Neilho,

    I've just found a catalogue page that agrees with my measurements for the 723 series. 14v/krpm tacho and 35v/krpm motor voltage constants. It quotes the max speed and voltage as...

    My 10ee had the most dreadful paintwork but the machine itself was in fine condition despite of it. No-one bid on it except me because of the apparent state. Fresh paint would have improved the sale...

    If you sand, grind or fly cut the base of the tailstock it's going to be low compared to the headstock.

    Orientate the shafts so the holes are at the high point then oil will run down the hole to soak the felt. Otherwise it will just run back out.
