Alex,

Are you sure it is stainless steel?

If it were my Maramu, I would have larger "small-pole mounts to the mainmast" fabricated in a machine shop from Aluminum and consider welding the larger aluminum mounts to the aluminum mast, although I am not sure if that would require a thicker mast or some sort of backing plate. Of course the new aluminum mount could be riveted. The Super Maramu small-pole mounts were made of aluminum and welded to the mainmast.

Also, if you decide to have these fabricated, you might want to announce that in this Group, because I am sure that other Maramu owners would consider joining the order.

SM "small-pole mounts to the mainmast" (circled in green) are aluminum and welded to the mainmast:

Hello everyone,

We own a Maramu rigged with the system of twin small and long poles.

The piece of stainless steel that attach the port small pole to the mast broke off while deploying the large pole. It's was held in place by rivets but they corroded away.

The rivet holes have been enlarged (see attached picture) either by corrosion or when trying to drill the rivets out so I can't just re rivet the piece to the mast.

I wonder what are my options to reattach this critical piece of equipement. 

 

Here iare the 3 options that I've though of so far:


- Redrill 3 cmm higher or lower on the mast and re-rivet. The issue is that the small pole won't be lined up with the support ring on the standing rigging exactly how it was before

or 

- Enlarge the holes and use threaded inserts - It sounds like the most robust option to me but I'm not sure if I'm capable of enlarging these holes without making a bigger mess
or 


- Have the piece mounted on a larger plate so that it can be mounted at the same height than before.

I would appreciate any suggestion


Here is a picture of the piece itself:

Here are the rivet holes in the mast


Here is the back of the piece


And the starboard side for reference.



Thank you so much and have a great day
