You can ask the folks at Rigging Only how they test their swages, or how they test/maintain their swaging machines etc. to keep them in tolerance. There are long-established standards for all of that...seems an extremely low risk situation. Millions of swages done over many decades, most for bigger boats and greater forces than ours. We hear about the very rare failures, not about the millions that never had any problems. I did know a guy in the Hilo sailing club who used only galvanized steel for all his rigging - no stainless. He was paranoid about stainless because, in certain rare cases, some types of stainless fittings can fail suddenly and unexpectedly, and apparently in those same rare cases, galvanized will not have the same type of failure. But at some point, this just comes from being bad at math - not understanding statistics. Sure that can happen in those rare cases, and, your actual odds of that happening are sooooo tiny. More likely to be crushed by a falling piano, etc. Plus some of it is due to lack of adequate inspection and maintenance - a.k.a. pilot error. cheers John On 5/6/22 12:17, Jim Sadler wrote:
That’s the problem
How do you know if it was done right until you have lost your mast.
On my M15 the top of the shroud has a mickeymouse crimped fitting with a thimble and a thru bolt in the mast. It has served me well for the 40 yr I have owned the Pelican. It seem like a similar rigging would work just as well at the bottom of the shroud only with "hardware store" cable clamps.
As I am rounding the west end of Catalina I would at least not be wondering about the workman ship and experience of the technician at West Marine.
Does anyone ever load test these? They do this with crane rigging as a requirement.
Thanx Dave for your incite on this and everything else you have helped me with
I am on a mission to rig the Pelican to sail in the "real ocean" and be able to respond to those who ask "Does this cute little boat really go into the ocean?"

Jim:
can't you get a local rigger to do it right? Or send them to a rigger by mail? West Marine Rigging, or any rigging shop, can make you a new set.

You mean hardware store wire rope clamps like this?

Or something else?
cheers, John
