Ooh, now you got me all nervous again. Do you need the screw to make the spare part?

These undersized screwed spindles seem to vary quite a bit Sven....So I prefer to machine a new cast iron nut to suit each spindle.

Ken,

Would this problem present itself even to those of us in the "low usage" realm? (3 to 4 hours per month) Or is it just on 10-20's with high volume?

Keep that threaded rod greased and it will be far less likely to fail under normal usage.

Mine was well lubricated

but way undersized.

Another one broke down same fault , this time in Japan ...Another repair kit one the way.

After several repairs on these I have come to the final conclusion that the spindles are a unique thread size approx: .547" DIA X 18 TPI UNF ... to have a special Tap made to this size I think would be very costly....and the best way to make the nut, is to machine the thread in the lathe to suit the spindle.
