Cp-16/lll mainsheet diameter

[mikew]

Hello, I have a friend who has a 1991 Compac 16-3. He is trying to determine the mainsheet diameter size. The blocks are made by Ronstan and have a 15 or stamped on it. It looks like 1/4" may be too small and 3/8 " ? too big. Just curious what the original diameter line may have been. Thanks.

Sounds like 5/16" is a nice compromise.

Ok Gerry, we got 5/16" which seems to fit the best. I also called the Factory and they said the same.
Thanks,
Mike
