Theres more action on this forum, so I'll through a question out there and see what happens.

Where the proctor spreaders are used on our wing masts, I am led to believe that the standard front strap is not used because its not long enough. So, Goodalls sells the front strap and rear lugs made of stainless for the arms. I have already recieved some info on the arms (that they 10mm thick), I thought since I've made most of my own stainless fittings, I would make these also.

Question - Can anyone tell me the distance from centre to centre of the pivot holes measured around the front of the mast? Or even easier would be the distance from the side scribe line to the centre of the pivot hole.

Theres a rib inside the mast forward of the scribe line this could possibly be the point I'm talking about, it looks very close in photos.
