Lloyds Pegasus - drive coupling

My latest ' re-visiting ' is this Lloyds Pegasus which I notice was mentioned on the Forum about ten years ago.

The machine starts and runs and has been known to cut grass. The issue I have with it is the worn condition of the drive coupling which will only get worse and ultimately fail with use.

Research into a replacement is ongoing; can anyone suggest a source ? I'm not sure quite what the material is but some time ago I had the idea of trying a leather offcut from a saddlers or similar. No joy down that route. In the absence of the real thing, alternative material needs to be quite tough but with some degree of give and flexibility. Also of course able to be shaped and drilled with reasonable ease. Maybe a tall order.

Any other thoughts  . . . . .?

I’ve seen similar couplings with the centre disc made of a thick rubberised canvas material , but I can’t remember the application. Chances are it would have been agricultural or horticultural . You can probably cut one from a piece of flat belting or conveyor belt.  Agriculturally, there’s a firm that still makes and supplies “ canvases “ for vintage reaper binders.

Just remembered where I’ve seen that pattern of coupling  , Ransomes Mastiff, but on a larger scale!

Have you thought of some rubberised conveyor belting, generally has a woven core, and has worked on similar applications.

Maybe not a permanent replacement, but is easy to replace when needed

Thanks for the ideas gents. Good to see someone still making parts for vintage binders and unsurprising to find that they are not too far away in rural Norfolk.

Between you and I, being a resourceful character, not to say a bit mean, I had been experimenting with a heel cut from an old wellington boot. It provided the flexibility and toughness but was difficult to cut accurately without burning or melting. With more practice I think it would have done the job though in the absence of anything better.

However, in the meantime I found a couple of offcuts of what I think were workshop/garage flooring tiles. Part of an auction lot of artificial grass I bought for the barn. Turned out to be more or less the correct thickness and much easier to work. Although quite light it seems to be strong enough and so far has stood the stresses. Should  last well enough for light use and demonstration purposes but in any event easy enough to replace again if need be.

Looks a good solution, excellent job.

As to being mean? I'm sure you devoured one of Celia's wellies :)
