Rigid vang end fitting

A friend of mine has a catamaran (36' I think) with a rigid vang. The end fitting on the vang made from cast aluminum has broken. I do not know the model but it has a large imprinted "S". He cannot get one anywhere so because I have a machine shop with CNC, I proposed to make one for him.
We will probably make his out of bulk Al but we could do it out of G10 as well.
He will probably get it at cost but as we will now have the capability to modify the CNC program easily, we could make them for various size vangs.
Is this a common problem on such vangs? If so, I'll figure out how to let ppl know we can make em.
G10 would require a paint because it is susceptible to UV but it is considerably lighter than Al.

Re: Rigid vang end fitting

There's a lot of force on that fitting, and it does a lot of stress cycles in a sail, so it's not that much of a surprise that it broke.
