ORF,

Have you got any hydraulic cylinder repair shops near you?

If so ask if you can have a look in their scrap. Plenty of round stuff will be waiting for you to re-home it[emoji3]

It would be quite quick to take a mould from it using either resin or rubber and then use that to make GRP or even concrete replicas.

I’m looking for a crank for a Perkins 103-10 engine if you have one. I think the engine is about 2005.
