John, and others. Your description obout the roller links is just what I did too. I went down to the local bearing supply house with a piece of cable I had put an eye into to see how things sized up. I came out with to very acceptable links. I choose two sizes. I use the RS41 rated average strength of 2640lbs for the control linkages such as aileron controls, and the RS50 (7050lbs, way overkill I know) for the flying wire to structure connection. The pins on the RS50 are just larger than 3/16" in diameter. From the Aircraft Spruce Catalog 1/8" stainless cable load rating is 1790lbs and the AN115 -21 ($3.85) shackle is 2100lbs. I feel comfortable with using these links. If you use the RS41 in a cable to cable connection it does not need any shims (washers) The RS50 is much bigger and I used washers as shims to keep the loads straight like John. For the RS41's I paid $.55 and the RS50's were a whopping $.70 each.Stevee> Steve,> > Here is a shot at a reply.> > I have incorporated a number of moter-sickle chain master links in my ship in> leiu of shackles.
