Does anyone know a source or alternative for the hard rubber bushings used on the Myford ML7 countershaft? As far as I can tell from the grunge encased remains of of the ones I have, all they do is support the belt cover so I suppose one could turn up something from Delrin etc if need be. But just wondering if something is available off the shelf as workshop time is severely limited these days. Myford don't list them (and I don't want to take out another mortgage).

Know nothing about Myfords, but hard rubber suggests ebonite! The same material that my clarinet is made of. A musical instrument maker/repairer tinkers with the material making bespoke barrels a small section below the mouthpiece…………..just a thought that may help??????????? John

Do you mean like this.

They are admittedly under the Super 7 Headstock section. I'm sure they will tell you if they are the same as the ML7 if you give them a bell. £3.60 each is quite cheap for a mortgage.

They’re not hard rubber or delrin and particularly not ebonite. They are pliable rubber used to prevent vibration of the belt guard. The super 7 does not have them.

When I was rebuilding an ML7 about 20 years ago I ordered up a pair of these bushes from Myford. When they arrived I was surprised to find they were soft rubber. I also discovered that they didn't appear to fit. After dialogue with Myford I learned that they were not fitted to very early models, and that they were a later mod. to reduce rattles. I may still have them, and if so you can have them for a modest donation if you can't source elsewhere.

I have a pair of unused ones which only cost me half a mortgage. I can post dimensions if you wish. They could be cut out of a thick rubber disc using the techniques in Sparey's The Amateur Lathe. The only other possibilities are to wait for a pair to come up on epay, as I did, or get some made. They are described as flanged rubber bushes (or top-hat bushes) but I couldn't find a standard part of the right dimensions. I'm sure somebody could get a batch made by such as grommets.co.uk and sell them on at a profit.

I take it that the bushes mentioned are to hold the belt cover in the raised position when changing speeds.

My solution was to wrap thin string around the shaft between the bearing housing and what was left of the flange on the rubber bush in order to press the flange against the cover.

Worked ok for me.

They are anti rattle bushes. Nothing more , nothing less.

Thanks for the good input guys and the several kind offers. It looks like I have the problem sorted. I shall post pics of the lathe later today when have time. Pretty sad state. In fact, the most abused lathe I have ever seen. If I give it a name it should be the Hesperus , as in The Wreck of. But the bed is virtually unworn, under all the hacksaw marks, chuck drop marks, job drop marks and ball peen hammer marks. Yes, ball peen hammer marks. It's hand tools should be licensed not guns. So the son and I should be able to tidy it up and maybe find something useful under all the grunge.

I tend to look up Polybushes for this sort of thing. May be of use when looking for rubbery stuff.
