Missing one side of the tack mount on DSII gooseneck

[TIM WEBB]

I made it myself. It's 5/16" x .049 wall SS tubing we use to make ripcord handles at work.

Yes, there was a batch of hooks made "the wrong way around", and I got one of 'em. It's supposed to go on the port side, but even if you try to put it on the stbd side it's useless ... that's why I made my own ...

"but even if you try to put it on the stbd side it's useless ... that's why I made my own ..."

See, that's why it's a good thing I'm stuck at my desk and can't get on the water. I read the posts here and find this stuff out ahead of time.

[TIM WEBB]

It's all good Alan - we all find out eventually!

I'm about to embark on this same repair. I have the new part in my hand, and I'm not understanding how new rivets will work to attach it to to the end of the boom? Will I need to re-rivet it on? Thanks for any assistance,

[TIM WEBB]

The new part will not have any holes in the "flange".

Just "dry fit" it into the end of the boom, and drill the holes for the rivets using the existing holes in the boom. Then use SS pop rivets to secure it.

Operating under the premise, that anything I put on, I'll eventually want to someday take off again (for at that time unknown reasons), I drilled and tapped for 1/4-20 SS screws rather than using rivits.

From reading around a bit I gather that rivets are indeed the better solution if you mount something on a relatively thin-walled tube. The fact that you have to drill them out isn't enough of a deterrent - how often do you change out gear like that? If the tube is thin-walled, it just doesn't have enough material to give the threads enough to grip, unless you use sheet metal screws (which are designed to work in thin material).

[TIM WEBB]

Yeah, I think the 1/4-20's would work as well.

GL, the threads would be tapped in the thicker flange of the casting. That's the way the mast hinge kit from D&R is installed. This link shows a good pic of the gooseneck casting flange:
