A stainless steel boma - DaveH - 04-24-2015
Another boma
I have 18 meters of 30 x 3mm flat bar to do something with.Going for rivets, and what a load of trouble finding some stainless steel solid rivets, eventually found a company that would make me 50.
It is not going to be as tall as the last one if fact it will be quite a bit shorter just over half and no fancy scrolls. There will however be plenty of banging and noise

Shows a prelim design and the size relative to the last one.

Because it will be riveted I need to make sure there is a reasonable fit between the inner part of the round straps and the uprights.
So all the uprights will have to be shaped.
A bit like this.

This stainless seems to weld very nicely

So, I had an idea
8mm round head bolt. - Clever eh
Phoned a company - can I have some 8mm round round bolts without the thread and no slot in the head
Answer "Sorry sir we can't do that"
Just a cotton pickin' minute .............. It says here 'We make special bolts to customers requirements'
"You don't understand sir ..........................."
If you don't make bolts to customers requirements why do you say you do, that's dishonest. So will you make them or not.
"Mutter mutter mutter ...................... I'll get back to you"
Rhymes with 'Trucking Tankers'
[attachment=10863] no slot and thread perfect

What you want to ask for is a stainless carriage bolt. That's the type which have the square head which is driven into the wood as it's tightened. You can always turn the square off in a lathe or grind it off freehand.
RE: A stainless steel boma - DaveH - 05-26-2015
I bought a couple a few weeks backs. I turned the square bit off. They don't look too bad, I would like them to have a deeper domed head and a smaller diameter.
I'm just getting too picky
