In yhis MEW the article on a saddle stop has a photo of the lathe with ,I assume,rolled spring steel protecring the leadscrew,which os exactly what I want to do..
Does anyone know where I might find some as so far I havent.Or something else I could use please?
Thank you

You just need to meet up with one of the many who had this feature on a new lathe and very quickly wanted to get rid of it. as it stops the saddle getting close enough to the spindle.

Actually I had wondered about that which is why I hadnt thought of another way! I ll just keep various bits of cardboard around as I have done..Thanks Bazyle

Hi Here Again,

Sometime ago I wrote an article for ME which showed a simple method of protecting the leadscrew on my Super 7 lead screw which is low cost.

In automotive harnesses they use a flexible plastic conduit which is split along the length and is available in several sizes. If you cut a piece of this and open it up along the slit you can wrap it around the lead screw. Being corrugated it can telescope a fair bit when it reaches a stop. I changed the Mazak thing Myford fitted to protect the lead screw and made a strip of ali which replaced it and added a hollow bush attached at the far end to run over the crest of the thread so it slid freely and that keeps the whole thing aligned. The spaghetti tubing is fastened by a nylon cable tie to the ali strip near the carriage and near the far end . When the spaghetti gets too messy I simply put a new length one.

The chap who does the "CNC Your Myford" conversions recommends Dyson vac hose. This seems to have an amazing capacity to "stretch". Also our Sebo hose seems similar.

Thank you both John s..I know people with Dysons!

Later versions of my lathe had these volute protectors for the Leadscrew, but I wondered about how much they would compress, (being Volute, they would , presumably compress down the to the length of one coil) But could not face the hassle of the strip down and drilling/tapping for the end fittings

. Some lathes have a cover above the leadscrew, which looks like an inverted, small scale gutter. Now that starts me wondering if something like that could be fitted above the leadscrew, on mine (might keep some swarf off the Feedshaft as well). Looks like another possible project.

I use 1mm polycarbonate sheet to make various protectors for the lathe. The polycarbonate does not seem to be affected by oil and slides over surfaces with very little friction. It can be bent cold into different shapes and easily drilled for fixing.
