Re: Maramu pole attachment to the mast broke off

I have a somewhat similar situation on my SM. A small cleat was ripped out of the mast and it pulled out the threaded inserts. I think the holes in the mast are deformed or enlarged just enough that the same size rivnuts/threaded inserts will not fit properly. If I drill the holes larger, then I don't think the next size up bolts will fit through the cleat.
I'm still pondering how to go about this. Ideally I'd like to re-use the cleat I already have. Open to any ideas or suggestions.
I think new rivnuts/threaded inserts is the way to go but clearly that comes with its own complications. I think you could modify the holes in your mast and the holes on the plate of your pole mount (if necessary) in order to fit new rivnuts and bolts. For me, I'm not sure drilling out the holes of the small cleat is a good option. FYI, a proper rivnut tool is very helpful when installing as opposed to using nut and bolt.
The dissimilar metals in close contact may have accelerated the failure of your rivets. Try to insulate or use something like Tef-Gel when you put the new hardware in.
