> I have a question concerning 'sleeving' (can't think of a better way to
describe it) - I have a 16' x 2.5" OD thick-wall aluminium tube that will
be used as a stub mast, would inserting 6' x 2" OD thick-wall aluminium
tube into the bottom of the tube add to its' 'strength' in any way or would
it just add unnecessary weight?
Sliding it in makes quite a snug fit, but not exactly 'tight'
Hiya, Steve --
Long time no see. Hope you're doing great!
What you're describing is a perfectly appropriate thing to do. It
doesn't have to be a tight fit in order to work. The bending moment will be at
the top of the tower where the mast exits so that's the best place to
reinforce.
Cheers & GL,
