I looking to use a set of old shackles to make an extended set for a couple of inch's lift on no budget. Its my daily driver for atleast the next 6 months and them will become our family weekend toy which will be redone with a proper 4-6" lift.
Plan is to either cut the existing legs of the shackles to weld new legs to the bush housing or extend the existing legs by welding a couple of pieces of either 1 x 1/4" or 1 1/4" x 1/4" flat bar to them.
Can I use plan old 250 grade mild steel or does it need to a higher grade? 250 is cheap and readily available in Australia
The low carbon mild steel is fine. Welding it to the stock shackles and doing a decent job is not going to be easier or better. The thickness of the tube and hardness of the rubber is enough for short tabs and low side loads. When extended, it will apply more force when cornering and cause the soft rubber to completely compress effecting vehicle stability. May be look at the bone yard for extended shackles?
Sorry man, I don't know enough about metals and tensile strengths to give thoughts on the topic.
All good, cheers

Ok cool, so the steel will be strong enough. I'll give it a go see how the bushes hold up
It's called "walking the cup" and is a used as a final pass on TIG welded stuff. It's cool watching someone do it. check youtube.
it's not ONLY used as final pass. The reason walking the cup is so popular for pipe welding is because it deposit huge amount of filler in wider passes with minimal time. Pipe welders often walk the cup for several passes. It's faster than weaving all the time.

I don't any first hand experience using the method though I have welded a lot of pressure vessels in the cryogenics field. I haven't seen people do much beyond a wash pass with a dab of filler when there is an opening. I guess I just need to see it being done correctly. Why would you weave and not to stringers?

I'm not as good as the guy from the link but I walk the cup anywhere possible. When I took a certification class for the 6g tig pipe cert the only way the instructor let people attempt the weld was by walking the cup. It is a pretty common practice in the industry so I'm sure sure where you have been ftwelder lol!
I got my first cert in '75 or so and never worked in energy or pipeline. I started welding Mongoose BMX frames in 1979 and mostly make custom bicycle frames and weird prototype stuff.
Did this just now in class, walking the cup on a 3/8 plate, mild steel, 35* bevel, 3/32 root opening, no landing, 1/8 filler, vertical up, 5/16 cup. That gold part in the middle is where my heat, speed and shielding were just right.
Love this stuff.
Up close on the 'perfect' part.
Reverse side.
It's not perfect, but it passed a visual inspection by my instructors, both AWS CWI's. Reinforcement varies from flush to 1/16. Filled with another TIG pass, 7018 and capped with 1/8 7018.
