If you were in the UK I believe I could help you. We have a CNC machine called a Seal Jet which we use for making hydraulic seals. The machine is made by a company called Economos (now owned by SKF). I did google it and find the link below, they would knock them out really easily based on a sample. Probably want to by in a batch, but give them a call anyway
Thanks Dawg for the link & MaineUltra for asking !
I just noticed how much mine shakes now and knew someone sold better ones.
I was gonna do a search here for it.
