Default Marine Leaning post remake

Ok, so this is a project I've been supposed to do for some time now!
For a buddy... first pic's are from his first attempt of bends and welds and the general idea of a leaning post for his boat now I'm not slamming the guy by any means cause I give props to anyone who at least tries to DYI... and the guy is a great Tattoo artist IMO! and I am one arming this project while teaching him some basic do's and dont's while I do's some don't

Plus I'm no expert nor am I like a skilled craftsman my self when it comes to fabbing up things either...

So anyway he made an attempt and pics are of his first attempt of radius bends with pipe bender on Stainless steel 7/8" tubing and the second set pic are of my radius bends now being one-armed I've had to use a little heat to help me use the manual tubing bender and it helped was able to use one arm to bend and went like butter with around 250 estimated degrees of heat...
These are pics of his Marine leaning post project attempt...

So far he is happy with the start and the new radius bends and me well hell yall already know I'm never happy with one of my repairs or projects cause it could always have been better IMO!

And so being somewhat limited limb at the moment among energy issues this project will no doubt take a few days for me to finish up.
but here is the beginning of the new remake of the marine leaning post project.
using a manual bender with as close a die to the 7/8" SS tubing as possible I think was a 22mm one bend in one rail has a little kink cause he was in a bit of a hurry and trying to help force it with putting pressure on the end of the tubing leg while I'm paying attention to the bender and die otherwise it would not have kinked...

New bends look good. How thick is the tubing?

IDK really didn't gauge it, but think it's prolly around 0.0625

I should mention I put this in welding instead of fabrication due to the fact I will be using (GTAW) prosses of the stainless VS his method of (MMAW)
Now I am not well versed in (GTAW) so We shall see how it comes out, I just figured its the best possible prosses to go with considering it needs to be as clean and nice looking as possible

So far so good. Just remember that stainless usually needs less heat input vs steel, so do not over heat it. If you do, it can sugar (burn) inside and cause future corrosion problems. You will probably be fine for intended use, but if it was for food use, you would want to purge the inside with argon for best results.

Yes, I am going to back gas it/purge with argon as the boat will be used mainly In saltwater conditions...
Spend most of the afternoon cutting pieces and saddling the cross tubing in the mill drill... had one piece taka flying leap the cheap V-Block clamp just gave away and broke in two so I need to make some decent clamps for my small set of V-blocks what they came with was look like junk cast metal of some sort chinesium go figure... But I got all 26 pieces cut and half those had to be saddled...

Maybe next time you can turn Vee-block on it’s side and pinch the tube and block in the vice. You can put a piece of paper between vice and tube so you do not mark it up. At work I use .003” brass shim stock to hold pieces that I want to avoid marking the finish. Just thinking this might have been more secure for you.

That's what I ended up doing... But got other Bigger problems with TIG side of that Horrid freight Vulcan machine the Omni 220 pro turns out The TIG is a mid-evil scratch start and That really sucks... plus I'm so darn near-blind anyhow even with my hood setting on shade 5... I can barely see to weld and my welds sort of suck too... so I thought...

But I think it is more the machine and contamination of my electrode dipping habit I have seem to of developed...

But turns out there are more issues coming in to play besides my eyesight and dipping habit... he told me the tubing is 304 and it is mixed 304 and something else and the filler rod is 318L,

I start out with my heat at 50 amps and bring it down a little once my puddle starts and it seems one piece is harder than the other and takes more heat to make fluid and when adding filler rod well it just doesn't flow just beads...
so something is going wrong somewhere I can't figure out I know I'm not so great at TIG but I'm not this bad at TIGing either...
