Thank you I know that I'm unsure how to unscrew it from the boom im not sure what I need to useThat is a clam cleat with a fair lead. He has one similar to it for sale at defender
The photo is not clear but that appears to be a rivet head. If so, it must be drilled out, or ground out with a rotary tool such as a Dremel.Thank you I know that I'm unsure how to unscrew it from the boom im not sure what I need to use
For a highly loaded application in a saltwater environment, aluminum would be a poor choice. However, this is on a 16' day sailer in fresh water the loads won't be very high, especially for the halyards.Seldon and other mast manufactures recommend, use, and sell monel rivets. Most beach cats, including Hobie, use monel. Aluminum sounds good, but in fact is more prone to corrosion and much weaker (which is why it is easier). But that is only what I have observed over the past 40 years.
It look like you will need a nose extender on the rivet gun to fit in the narrow channel. Depends on the gun and the nose piece shape. A stack of nuts or washers can work.
I would not chose aluminum rivets for a highly loaded item like a clam cleat.
Agree, but for higher strength I'd use monel rivets (not stainless steel)For a highly loaded application in a saltwater environment, aluminum would be a poor choice. However, this is on a 16' day sailer in fresh water the loads won't be very high, especially for the halyards.
I prefer monel rivets. But you'll need a serious rivet gun to put those in.The boom is aluminum, use aluminum rivets not stainless steel. The SS rivets will corrode.
If it is for a one time use, I suggest that you beg, borrow, or steal that "serious rivet gun". They can be very pricey.But you'll need a serious rivet gun to put those in.
under $50 - do a web search on long handle rivet gunIf it is for a one time use, I suggest that you beg, borrow, or steal that "serious rivet gun". They can be very pricey.
PS Just kidding about the stealing part. Maybe renting is a better idea.
I've not had problems with stainless, but monel has always seemed a step up. My rivet gun is such that I wouldn't be able to do what you suggest above as the lower handle is what moves. If it were the other way around I suspect that's correct - as you say, a couple are OK, more than a dozen and get me a bigger rivet gun...I've never found monel or stainless than difficult with a standard gun, if there are just a few. Use both hands. Better, block the lower handle and lean on the upper handle. If there were more than a dozen, yeah.
more than a dozen and get me a bigger rivet gun...
Not completely True.For a highly loaded application in a saltwater environment, aluminum would be a poor choice.
Aluminum might be an ok choice from a corrosion standpoint, but it’s significantly weaker than any form of steel or monel, so not a good choice from a strength standpoint if highly loaded.Not completely True.

Do your engineering then.Absolutely not, the shear strength isn't there
