Alloy A frame/mast
I'm wanting to construct an A frame of sorts from Marine Grade Aluminium Alloy plate. The structure will consist of two profiled uprights (closer at the top than the bottom) with cross bracing at the bottom, 2rds up and at the top. These side profiles will have large holes cut into to remove excessive weight.
I'm hoping to have the whole lot Anodised.
I haven't seen any boats with this type of frame before and there's obviously a reason for it, Cost, Looks, Practiablility of such a frame.
There are several people on Boatmad that have experience of working with Alloy that I would like feedback from, so if you would have any suggestion I'd like to hear from you.
