Ah....Yes. Not sure about 660 bronze, but Phosphor bronze is acceptable.What did the plans call for on the stays?Davehi steamerthe drawings show that the stays are 3/16", all the bushes are bought from a well known steam fittings place.Bronze - SAE660 Free machining Leaded barNot subject to dezincification. Ideal for boiler bushes, bearings etc.thanks dave.

Hi Dave,If the plans call for the materials, and the dimensions specified, what is the question then?Davethe drawing tells you what materials to use and sizes but not how to do the stays. like i said in my first post.
As I said earlier if using bushed stays then all the ones I have seen thread the full dia of the stay. The bush is then threaded internally to fit the stay and externally to fit tapped holes in the tubeplate. I suppose you could just solder in te bushes but I would prefer to see then full dia all the way.I'll scan a picture later of a drawing that shows then done this way.I have never had a problem silver soldering 660 and it is resistant to dezincification so no problem in a boiler though I mostly use it for fabricated cylinders.J
