06/01/2001 11:04:05 AMHi List,As I continue my reading & planning, I have seen very little reference tousing stainless steel for the metal fittings & fasteners. Does anyone haveany advice on this? I assume that there are ss equivalents of 4130 and ANhardware? I know that in marine applications, we generally have to beef updimensions by 10-20% to use stainless. I also assume it's going to be moreexpensive. I keep having this fantasy of not worrying about corrosion &showing off beautiful satin-finish ss parts.Cheers!Kip GardnerDept. of Ocean, Earth & Atmos.

Concerning Stainless; I had the same concept of using stainless on theexposed items where possible. However I had already fabricated all on myfittings out of 4130. Having access to some stainless I have made my liftstrut brace cable fittings out of stainless and installed them withstainless bolts and nuts.. I don't think relative strength of stainless vs4130 is a big deal. Remember this is an old design which originally used1025. In making my fittings I do a quick equivilent area comparison and ,i.e. shear area of the bolt vs the cross section of the fitting and itsusually at least twice as much which should easily handle any tensilestrength stress. And yes they do look nice . I find that when I made a4130 fitting, applied rustcure, primer and finish coat, then installed it ,it was all scratched up anyway. I'm using aluminum struts, lift andcabanes and that will eliminate some more painting too. I may rework thestab and vertical fin brace fitting in stainless too. Also got somestainless wire for the braces, about .060 dia. Just another way of skinning the cat.Lou Larsen----- Original Message -----

06/05/2001 11:43:58 AMHi List,Thanks to everyone who put in their thoughts on this topic. It sounds likeit's one of those 'it's nice in theory, but...' kind of deals. Jack, thanksespecially for your comments re the working qualities of varioushi-strength stainless alloys. Yes, I know from my own experience that'stainless' is not an absolute, try putting something on a ship & runningit through a couple hundred salt-water immersion cycles & watch whathappens, even if you do rinse things off in between. Sounds like I'll beusing 4130 & painting with some sort of epoxy or trying powder coating. Ona related topic, it's good to hear the comments about Replicraft's parts, Iwas think ing of buying some parts from the, so now I know to be carefulabout the ones made for the 1929 plans.Cheers!Kip GardnerDept. of Ocean, Earth & Atmos.

06/05/2001 05:02:44 PMMark,Glad to hear you had a good time at College. I have said it before, but Ireally think that the best way to work with William is in person. Theafternoon I spent at his shop last winter was key to my decision to use aCorvair converted by his method. The way he related to my wife was also keyto her finally feeling comfortable about me going ahead with this project.If at all possible, I'll be there next year with an engine, ready to getthe most out of his assistance.Cheers!Kip GardnerDept. of Ocean, Earth & Atmos.
