Hi all,I am Dad!
Re the suspension cushion material,I have found some poly ethylene (High Density)Sheet 6 mm thick black.I have made up a simple drawing tool male and female and the sheet draws in this mold under the press when mold and sheet is around 110Deg ,must not exceed 200 deg damages it .What i have found is that it needs to cool whilst pressed as it draws back a fair bit if the press is withdrawn straight away.When set the lower slotted hole can be milled,then the rectangular residu jig sawed off,then final finish on a off hand grinder.Then align with slot in casting and knock in with press male tool.Remove press tool and give it several hits on the edges of the cup.Its then ready for drilling.countersinking inside the cup then riviting.
Now it looks good and I hope it doesn't squeeze out.Alex will post some photos soon.
Regards,
Bruce.
