[TowerTalk] Yaesu 800 rotor pin ?

[Mpridesti]

I had mentioned a 9 mm size but that is for the hole. Yes the bolt has a 8 mm diameter. 

Additionally I have found that if the mast is aluminum, seldom have I needed to pin but if the mast is steel, I can never get the clam shells tight enough around the mast to either prevent slippage or cracking the shell, so pinning is required. 

Regards,

Mark, K1RX
