question for the welders here
anyone ever fabricated SS racks or weight baring structures here? I'm
wondering how comparable X gauge of stainless tubing is verses the same
gauge of carbon steel... and what grade of stainless might be up to the
task. In other words how light of a gauge would you recommend for a rack
(say a safari style roof rack) that has to support a few hundred pounds.
under varying load and flex while driving. I be using it for a canoe,
gas can, camping stuff; that sort of thing. Is there a rule of thumb
like if 14 gauge steel tubing would do the trick, you'd need 12 gauge SS
to get comparable strength? Also what thickness SS would you recommend
for a swingout spare carrier with single mounting point roller bearing
hub attached to a beefed up rear cross member (replaced the stock 1/8th
thick cross member with 1/4").

Re: question for the welders here
Although sometimes increased strength might be a byproduct of the alloying
procedure....usually the resistance to corrosion is what Stainless steels
are alloyed for, some of the metals used in the process are not as strong
as the original metal. The actual process used to form the metals
originally and then the method used in the shaping of them also have a lot
to do with the strength and ductility. One thing I look at is if someone
already makes something similar to what you want...try to find out what they
used for materials (Several manufacturers offer bumpers/bars and racks etc
in SS). Also stainless steel does rust.....just slower than carbon steels.
If you want something up there to be shiny.....chrome it.

there is no significant difference.

depends. do you want to eat off it or just use it to hold things?

i would build with 11ga., but i overbuild _everything_. while its more
durable, its also needlessly heavy......but thats just how i build things.
14ga. would be fine, even 16ga. if youre only talking about a few hundred
pounds.

i would build with 1/4" 2x2. bear in mind there are a few things to know
about stainless. i recommend you tig it, but if youre going to mig it first
practice on scrap. also if you mig it be sure and use a tri-mix gas
otherwise the welding will effect the corrosive resistance of the stainless
in the HAZ causing rust.

Re: question for the welders here
I built a bumper and tire carrier out of 1/8" 2X6 and 2X2 tubing. I've
landed the Jeep on a few rocks on the rear bumper and it hasn't even dented
yet. I like you had to beef up the rear crossmember to hold up to a bit of
abuse.
