Does anyone know of a source of cover springs to go over a leadscrew,
I'd like to add them to my lathe but can't find any source. The wound
flat strip coil-spring type that I'm after used to be made by
Tensator, but these days they only make Post Office barriers and the
like, no 'engineering' production :-(
A few other people make the straight extension constant force springs
that Tensator also used to do, but no one seems to do the conical coil
springs.

Thanks
 Richard

Hi, there are a couple on the internet you could try, Spiroflex.com and 
Henniguk.com, hope this helps

The following link will take you to a list of standard sizes but does
not show the cost. My 2007 catalogue shows N6236 the cheapest at
£25.79 and N6719 the most expensive at £168.38.

Before you get one, wind the saddle towards the headstock as far as 
you'll ever likely to go, then measure the space available for the fully 
compressed spring. You might find there isn't enough room for it. I had 
to remove the one fitted to my lathe for just this reason.
