I'm trying to think of the cheapest method.
Sure, but that isnt necessarily what the OP needs, he may
just want something that isnt very overpriced like the one cited.
Yeah. Those are trash gold gold.
But not hard to find if you dont insist on getting it from the trash.
Plastic strip stuff? What do they sell it as? I am curious.
Not sure what they call it where you are,
I am on the other side of the world to you.
Actually it is.
Nope.
All welders have higher concentrations of heavy
metals in their bodies than anyone else on Earth.
They do a lot more welding than that project will ever need
and like I said, you can always do it outside if you are paranoid.
Breathing metal fumes is very hard on your organs.
Nope, I welded heaps of stuff when building my own
house physically and never had a single problem.
One thing you *really* don't want to do is smoke while you weld.
I'm not stupid enough to smoke and its unlikely that anyone
who is that stupid will see much effect from the welding alone.
And thats a problem with asbestos, not with welding anyway.
No maybe about it.
Every material has it's limitations.
Yep, thats one area where wood is very poor.
Its fine for the shelves tho.
Metal would indeed be pretty.
Yeah, works very well with the furniture grade RHS which
has very square corners. Not as easy to weld tho because
the walls are thinner than normal RHS. Very practical tho,
I did all the builtin wardrobes and shelving that way, with
slotted verticals welded into long thin rectangles bolted
to the concrete block walls. 1" square tube.
