Hi Bernie, I used to have a Ford V6 with a Blanton Drive = 211; there was no TV damper built into the 2:1 ratio drive.

Near the end of my V6 days I contacted a guy in British Colu= mbia (Mike Hirshfield) about his V6 installation which was very successful ̵= 1; he was flying exclusively on floats and had a NOS system which boosted his = rpm to 4800 on take-off – he claimed better performance than Cessna’s = with 0-470’s. Anyway he had a set of drawings for his reduction drive R= 11; I couldn’t make sense of them – he said if I took them to any machine shop they would be able to make the necessary parts.

If you’re interested, I’ll dig them out and try = to get you a copy.
