Wouter,

I have an AHPC mast base casting similar to what you have on your F16. I have the stock diamond wire configuration where you can only add tension by dropping the mast. I recall that you said you added closed-body turnbuckles to your diamond wire configuration so that you can adjust diamond wire tension without dropping the mast. I have a question regarding your diamond wire configuration:

Did you do anything special to prevent the wire that feeds into the bottom of the turnbuckle from turning in the mast base casting when you turn the turnbuckle?
