Unless I’ve missed something WHAT is this material ? Blue plastic, I was using moly filled acetal 30 years ago. As to being a substitute for bronze, I think that’s stretching things a bit ? Noel.

I didn’t catch what the material actually is.

We used to use various forms of Turcite around 30 odd years ago, mid 90’s to about 2000. Some were metal filled, others had different fibres added etc.  Then went back to bronzes, like LB2 and Ali Bronze. Now we buy the bronze with the carbon rod through it. That seems to last the longest for bushes on hard steel pins. The moulding machine platterns and tie rods , use the carbon plugged Ali bronze bushed. The bushes were still within the original machine specs, and the rods/bars needed to be replaced in the service last year. Normally it is both bushes and the rods/tie bars are replaced after about 6 years or so.

Anyone holding rectangular stuff in a three jaw chuck, or using a tap as a centre punch should be taken away and chastised severely

Couldn’t agree more, why would we believe the rest of it?

Its supposed to have 10x the wear resistance of bronze.
