    310833

    It might be true that it was available to Monarch prior to 1943, but it might not have been available due to rationing and prioritization until after WW2. Monarch may not have adopted it for some...

    I am not trying to make a federal case about this. But, I guess what you mean is that you have seen round dial lathes that seemed to have ductile iron apron levers. I suppose it is plausible that...

    I think the plastic/foam cases would be great for travel. Bombproof as said.

    How could that be since the EE was introduced in 1939 and ductile was not invented until 1943 with the patent application filed Oct 25 1943? That’s after my lathe was shipped.

    The ball end on my original EE handle is roundish but not as und as a ball bearing.

    Making it from ductile iron would solve the problem of breakage. Ductile iron was invented in 1943. How long...

    Sounds like an interesting approach. I’d think when the assembly you suggested was pulled from the oven, wrapping the “dumbbell” ends in ceramic wool would enhance the mass effect you cleverly...

    It may also be useful to remember that the profile of the thread cut or ground into the spigots on the crank need to be reasonably close to ideal, but do not have to be extremely close to “perfect”...

    You could harden and temper the whole works. Then wrap wet rags on the crank leaving just the spigot exposed. Heat the spigot to reduce its hardness to maybe Rc 45 or so by heating the spigot to 1200...
