I have a old Hifly board and with Akutec base. The tendon finally broke and are not available anymore so I have bought a Boge joint and will modify the base to make it work. The problem I am having is working out what the thread is in the Boge joint. Its says M8 but when I fit an M8 bolt is still feel loose....it still has some side to side play.
I have taken it to a bolt supplier and they could not figure it out. Does anyone know exactly what thread it is?
Prolly Boge joint is old stock
Go back to bolt shop and try imperial 5/16 National Coarse or even Whitworth
Edit. sorry thats wrong 8mm (.315") is actually 3 thou bigger than 5/16 (.3125")
