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

http://kindred-spirit.net/morgan43/arch/archradar.html

This shows the design of a radar arch for a Mogan sailboat with a
prototype build from PVC. It has a nice innovation of seats added to
the pushpit. Well done....Lots of good size images

Can anyone figure a price on what the fabrication of this arch would
have cost in materials and labour (welding stainless) - excluding the
building of the prototype?

http://kindred-spirit.net/morgan43/hardtop.html

The author of the website built this themself. It looks nice but it
sure took a long way to get there as they used a mold. Not the way I
would have necessary approached it, but it seems to have worked.

Other upgrades.

A stainless steel arch built by wells marine out of 1 1/2" tubing with
dingy davits, solar panel mounts, stern light mount, flag pole mount,
stern pulpit would be about $5000.

Oops. Perhaps. More like 6k, based on my recent build. There's a
bunch of gotchas in his price list; by the time you add it all up (with
him, not apparent unless you've had the detailed discussion with him),
it all adds up.

He uses 1.5" 304 without passivation of welds (polishing only) - a
prior responder to my search here earlier indicated that he was
constantaly having to polish it (the entirety) due to corrosion.

That said, I seriously considered a Wells arch, but in the end went
with a custom builder because, at any price, Wells couldn't do what I
wanted due to their cookie-cutter approach (saves costs, of course -
doesn't impact quality) - and in the end, his price was the same as my
2" custom fabrication. See my gallery
(http://www.justpickone.org/skip/gallery/) under M46Projects for a very
detailed look at how I did it - without having to build a prototype.

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.

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?

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."

You will recall how similar this is to a popular, safe and effective
method of rust removal in regular steel fittings.
Connect the positive side of a battery charger to a lead or stanless
anode plate. Connect the object to the negative cathode lead,
Immerse both electrodes in a solution of baking soda or TSP
(tri sodium phosphate.)
This is cathodic reduction - the opposite of anodic coating of
aluminum - where a hard oxide layer is added.
The baking soda is much safer than acid solutions, in that it spares
the bare metal.
