Stainless steel cat frame


Long time reader, first time poster.
Thought I would share a stainless steel frame I made for a 14' legend.
Thanks for all the help engineering this

I don't know what it weighs but it feels heavier than I thought it would.
It is made out of 1"x.065 and 3/4"x.065.
If I were to build another,I think I'd use 3/4" thru and thru and maybe even a few thousands thinner on the wall thickness.
Thanks

On the tubes

It will weigh the same as steel. Did you purge it during welding?

John,
I surely considered it, I would have had to drill at least one hole at every connection to get argon thru it all, i got lazy and said let her sugar.
I also talked to a buddy that made some airboat cages that were holding up well with out purging. Do you think I should have purged it?

Purging is the best but there is a product called solar flux that works well for what you are doing. It looks nice and I can appreciate how much work went into it. Good job.

I googled solar flux and it would have been a great way to go on this project.
I had no knowledge of it till now, but I've been away from that part of the pipe trades for awhile.
Yes, it was quite a bit more work than brazing a emt frame together.
As you probably know that stainless draws worse than about anything.
I tried my best to pre camber everything and out guess how much it would pull.
Even at that, it is not totally straight.
The good news is it did not twist and has a nice gentle even arc from starboard to port.
Kind of like a cambered bridge beam.
Thanks for the kind words

Nice work. Usually a 75% argon and 25% CO2 mixture is best for thinner stainless.

Are you going tubing with this setup?

I'm a self proclaimed/wannabe engineer and designer. Function is without question, but then I love style! That thing is beutiful!! Make sure you add some pics to the "raft porn" thread. It can use some more pictures to go with all of the gabbing.

Thanks milehigh,
But i don't think i'll do another out of stainless.
I have been thinking maybe titanium, it would be bad expensive but way cool.
