ARCH - RADAR/DINGHY & HARD TOP Layout - Design - Build

Skip, There is a way to passivate the welds after the arch is installed. I am using a product called Citrisurf. Wrap a short length of stainless tube with a rag, connect the + side of a 12V battery to the tube and ground the arch. Dip the rag in the Citrisurf solution and rub it around the welds for a few minutes.It is not as good as a real hot dipped passivation but it does restore color and slow the rust stains. It leaves the surface a little hazy where it has eaten away the free iron molecules but it can be shined up again by hand with normal stainless polish. -- Glenn Ashmore Hi, Glenn, and thanks for the thought. How was the BVI? Meanwhile, my SS local welder uses Lime Juice, rag wrapped, a day or so with refreshment, to do the same thing. Would an electrical current on the rag imporove that? And, my objection to Wells was his inability to do what we needed, at a comparable price to a substantially more robust rig, passivated at each weld. His use of 304 was an incidental, as I was still headed his way until he couldn't build "my" arch. 304, of course, is stronger, so perhaps my upsizing resulted in similar strength at the end. How did you do *your* passivation? L8R Skip, now in rehab from nasal/sinus surgery, and hoping for release to active therapy on the shoulder next week.

In or out of 'em, it doesn't matter. Nothing seems really to matter, that's the charm of it. Whether you get away, or whether you don't; whether you arrive at your destination or whether you reach somewhere else, or whether you never get anywhere at all, you're always busy, and you never do anything in particular; and when you've done it there's always something else to do, and you can do it if you like, but you'd much better not." |
