Boom assembly

So I have a new boom, sliding gooseneck and end cap, but not sure how the gooseneck and cap stay attached to the boom. There doesn't seem to be any way to secure either. They just fit snugly in the boom. There are 6 pop rivets that came with the parts, but I have no idea how they might be used to attach the gooseneck.

Here is what it looks like:




Anyone point me in the right direction?

Re: Boom assembly

Assemble the boom and end fitting, drill through one wall of the boom and and fitting, and pop rivet in place. Since they gave you three rivets for each fitting, I'd guess that you'd place the pop rivets at 10:00, 2:00, and 6:00.
Alternatively, assemble the boom and fitting, drill through one wall of the boom and fitting, tap threads, and and install SS machine screws

Re: Boom assembly

Slide the parts together tightly, drill through the boom and the inner 'shoulders' of the fittings the right size for the rivets, then get hold of a pop rivet tool and put them together.

What boat is this on?

Re: Boom assembly

Thanks for those fast replies. I guess that makes sense. It seems like those pieces are solid, I was not sure I could drill just part way and pop a rivet into them.

It is for an O'day Rhodes 19.

Re: Boom assembly

Solid?? really?? I'd expect a 3/16 or so thickness on the parts that go into the boom section. If they are solid then you'll be better off drilling and tapping and using machine screws, or, as our Selden rig has, drilling and using self tapping screws to hold the end caps.

A rivet is really meant to have the room to expand beyond the bore, so simply drilling a dead ended hole may not work too well.

I have almost identical fittings on the ends of my boom. They are screwed in with self tapping screws.

Re: Boom assembly

Okay, I will check on the thickness, maybe they just appear solid, they are hefty. But I bought it all together from Dwyer, I'm sure they would not send rivets if something else were needed.

If the rivets will not do I will try the self tapping screws. I appreciate all of the responses.

Re: Boom assembly

There was a 'shoulder' to drill thru and pop rivets into, so I am all set now. Thanks for all of the assistance! Now just need some help stepping the mast and I'm on my way.
