Thread: Forth road Bridge nuts
31/03/2012 20:28:45

Not sure where the mystery is for tightening nuts/ bolts.I run the engineering section in a factory processing plastics.I insist all my workmen and contractors use a torque wrench at all times when tightening up critical fasteners.We have wrenches that go up to 1500 Newton meters plus and also torque multipliers which increase the applied torque by a factor of over five times. There really is no need to swing on spanners with metal tubes or smack them with hammers etc.(although I have seen this done on many occasions). If you were to look on the bolt manufacturers lists they will give you the maximum permited torque for their products. Over tightening is not required as it can seriously compromise the fastener. I have produced lists showing the settings required for the different sizes and types of bolts we use.Some of our bigger dies have 40mm high tensile bolts and these are taken up to quite high tensions (still below the manufacturers limits) all we use are the correct tools for the job! Simples.

Thread: Old watchmakers lathe

Hello Clive,
 
       I can't give you a definative answer since I don't own an IME watchmakers lathe.However I do have the 100 model instrument lathe which has a very similar bed if you look at the pics. on Tony Griffiths site. The bed on my lathe is simply drilled through and counterbored in one place at each end of the bed and secured with (1/4?) caphead screws.
