The most dangerous thing here, quite apart from his refusal to get proper help, is the fact that there is earth leakage current on his lathe.

Left unchecked it could potentially kill him.

Get that sorted out first by a competant electrician and stop all this guessing!

Surely even if a nyloc nut has been used, it can be used again, provided that it goes back on stiffly. The same applies to the other types. If they are doctored and go on tight , then they are unlikely to loosen off. The proof of the pudding is in the eating.

Just to fill you guy's in where the piston rod is fitted into the crosshead on my traction engine a tapered dowel pins is used it should be a small tapered wedge but in my case it's a dowel. The one I fitted last time was very tight when I came to remove it and I damaged getting it out I will sometime in the future make and fit the small tapered wedge.

Harry,

It looks like your opening question was the right one to ask !!

What I don't think you have told us is whether the tapered holes already exist.

i.e. are you making something, or refurbishing it ?

This is significant because, as mentioned by others; you need a tapered hole for a taper pin.

If the hole already exists, you need to measure it carefully ... and if not, you will need a reamer.

Given the close similarity between 5/32" x 2" 1:48 and 4mm x 50mm 1:50 ... be very careful to check what people are trying to sell you.

If you have the reamer, it's best to put it in the lathe and set the top-slide to match its taper.

If you don't have the reamer, then you could make a D-bit version from Silver Steel, and turn it and the Pins at the same top-slide setting.

Of course; Clive's roll-pins have merit in the appropriate situation.
