OT: What's this type of bracket called?

[Sylvia Else]

https://www.dropbox.com/s/b4b15o0hgno2ldu/bracket.jpg?dl=0

The perspective is a bit off - the angles at the end are about 45 degrees.

I made this one myself out of aluminium tubing, but I've already had one
crack and break at the bend.

So I'm trying to buy a steel one, but I can't even figure out what to
search for.

Best of luck with an off the shelf replacement, Why not use some 5mm
flat bar (steel) from a steel suppler and make it

That's a support bracket.

I'm sure I've seen this kind of bracket in various applications. I
suppose they may all be custom manufactured, but I'd have thought they
were common enough to be something of a commodity item.

Looks more like about 7mm.

I would buy some brass tubing and recreate what you have, then go
have it chromed.

The term you want to search is "gusset" or "bracket" or "strut".
And if you use google, select "images" first and then you get
hundreds of samples to look though.

Hard to find a single rod type like that. Most are the angled
portion and a flat horizontal part in tandem.

That is why I suggested making one from a tube segment and a hammer
and drill. If you use brass, you wont need to chrome it. If you use
stainless, it will be difficult to fashion.

I would call it a tube brace or strut. They also make them out of u-channel which I often see in building.

http://catalog.powerstrut.com/?product=45-degree-tube-brace

https://www.usesi.com/power-strut-ps-812-12-eg-electrogalvanized-steel-45-degree-diagonal-tube-brace-601380

Doesn't look like either of these pages let you order any.

No. Much less from Australia. Thanks for the links, though.

I thought about using u-channel, but it would need to be welded, and I
have no welding equipment (nor welding skill, indeed).

It's just a generic support bracket ghat manufacturers make for specific
applications. You won't find one on the shelf anywhere unless you get
*really* lucky, and the reason why it's cracked is because you've made
it out of the wrong material for the application at hand.

As DBR said, get yourself some 5mm flat bar (in whatever width you
fancy), and make a replica out if that.

Not welded, but you would need some equipment that could cut and bend the metal. Cut at the edges so you have three flat parts and bend them to form the 45° mounting surface. Possible to do this with a hack saw, but the bending is still hard. You would need to be resourceful.

nuh. just get a short galvanised steel strip from bunnings for a few
dollars, cut it to length if necessary, bend the two ends to the right
angle, and drill holes for the screws.

Leg brace.
For a wood table, you'd use a isoceles wood triangle, beveled to match the table
and notched where it affixes to the leg, or design with a skirt for LARGE wood/wood
contact area.

A simple rod won't keep the leg vertical, it needs TWO rods to make triangle-rigid
in two planes. The bend is a weak point, so bevel-cut-and-weld is the better
way to use steel in this application.

I was going to try that this afternoon. But my blow torch is empty.
Strange, as I've barely used it. Slow leak? Or did the workmen I had on
site for a couple of weeks just use it?

Sylvia.

It's work hardening, that's why it is cracking. The annealing before and
after should reduce the risk of that happening.

If you are talking about a propane cylinder torch you should unscrew the head from the bottle if it is going to be idle for some time. The cylinder has a good seal in it. The head not as much.

It's not about how weak it is compared to the rest of the strut. It's about how strong it is compared to the requirement and the cost. Welding is very expensive compared to thicker metal in a strut like this.

Here you go again, trying to make yourself relevant. Firstly, you have
absolutely no idea what the *application at hand* is since it was never
explicitly stated. You just wanted to make your statement sound
impressive but all it's made you look like is a dick. And you're good at
that!

As DBR said, get yourself some 5mm flat bar (in whatever width you
fancy), and make a replica out if that.

The bracket cracked because it was *work hardened* in the forming
process and required annealing before and after to *reset* the aluminium
and relax the internal stresses.

Didn't you ever do any metallurgy studies at Richmond Tech? Before you
dropped out, that is!
