This new list format seems to result in that, through our own human error no doubt. Steve and I have been having a discussion on wire rope rigging; and also another one on cable lay nylon rope, which is much more elastic than a standard lay nylon rope. We have tried to make sure to remember to post everything to the group; but it is very possible that we missed doing that a couple of times. >Cold swaging of SS rigging is >well-established for boats.

In fact, the presses came first, before the rotary swagers. Most of your medium sized commercial rigging shops are still using the presses. The main advantage of the rotary swagers is that they are faster, and perhaps they also require a little less skill. You will find the rotary machines mostly in the high production shops, and also in shops that do not deal with large rope diameters. Rotary machines for large rope diameters are very expensive. >316 SS wire should be used and >the fittings should be installed with lanolin on the inside. A number of different lubricants are used. If you buy lubricated wire rope, then that is sufficient for the inside of the swage. The outside of the swage must also be well lubricated when pressing. >Sailors have >argued mechanical (Norseman/StaLoc) vs swaged for dozens of years with no >consensus.

I suspect that you are right. >Have had no experience with wire rope, but I don't think it will sell in >the cosmetic world of recreational boats. Sure you do. All but rod rigging is wire rope. It is just a question of what the wire is made out of. Most recreational rigging is made out of 316 CRES wire rope. Most commercial marine rigging is made out of XIPS galvanized wire rope. >Now back to my original question: Am I missing something in this >thread?<G>.

I must confess that I know very little about wire rope, but have been called upon in past lives to spec out swaging equipment of both press and rotary type. Properly tooled, the human skill element can be eliminated from either type machine with regards to the strength of the final product and no one beats a good old-fashioned flywheel press for speed. The rotary press can usually be called upon to do a prettier job with no die marks. Example: Check out a tapered front fork on a bicycle. There is usually no finishing process between swaging and cleaning/painting on this part. The part is usually rotary-hammer-swaged to a very fine surface finish, bent, assembled and painted. Ed
