Sleeving broken aluminium mast


Recommended Posts

G'day I've picked up a Aluminium Taipan 5.7 mast thats broken about 3ft from the base and I want to repair it as a spare to keep at the club. I have mast section to sleeve it with and I have cut the twisted pieces of. My plan is to put a new section on the base then internal sleeve followed by an external sleeve to be welded.

My question is what length would be right for the internal sleeve?

What length for the external sleeve?

Welding of masts is generally not an option as masts are made of 6061 T6 grade alloy which has a specialised heat treatment to harden it and you could not replicate this with just welding. Internal and external sleeving on the other hand is an excellent method of joining broken masts, as Darcy has said, be sure to stagger the rivets and don't come any closer to an edge than 3D.
