Piston Ring Question

[Dick_Morris]

MrCrispin has just posted an excellent tutorial on his method making cast iron rings. All done very elegantly. https://www.youtube.com/watch?v=DsW2IxQfshA

Turns out it was Hercules Sealing Products, PS1600 series of hydraulic seals.

Does anyone know if these will work for piston valves?

Nah, those won't work for valve rings. My Kozo is slide valve. Don Yungling mentioned using cast iron transmission hook style rings in the piston valves of his his SP GS-1 with bronze liners. $.02

I'm not a super fan of the hook style rings because the hooks prevent further expansion once they are worn, effectively causing a plateau in performance. The non-hook style rings will continue to expand as they wear giving a continued gradual decline in piston performance.

yes...but on some you can file the hooks off and have a flat overlap
