Keeping it square

[daveA66]

Hi

I have no idea is this is the correct section for this query - it probably isn't but as it involves soldering copper pipe I though I would start here

The images show the fram for a copper pipe bar stool I am making. All the other projects I have done have been simpler than this but I have a particular issue with this one which is what is the best way to keep all this square while soldeing?

Should I assemble the whole thing or try to do it in setions?

Any advice or ideas appreciated.

At present it's held upright by the bottom of the legs being inserted into stop end that I have screwed to the wood.

1. No pictures.
2. I'd be very surprised if copper pipe is sufficiently strong to make a bar stool, a full size one anyway.

Hmm, not sure why the pictures are not displaying, it looks ok to me.
They are on my one drive, i will try to find a different way of posting them.

Stool is not very high about 60cm, 22mm pipe with 15mm cross braces.

First one is a prototype anyway. I will try to get the pics posted again.

For the benefit of the thread:

To me, those back legs need a lower cross support L>R and F>B or they will easily be bent out of shape.
Soldered joints are not IMO going to be strong enough to provide a strong support.

It may look nice when finished, but not very practical.

Would compression fitting be a better choice?

Also, how dod you get the images to appear? using the insert image bit didn't work for me

Cheers

There are some quite flimsy looking ones available commercially....

Just copy and paste into the post

Yep got it thanks

You may find that's not copper rather steel that has a copper coating or does it say it's copper?

Not looking to put a damper on your creative skills but copper is stronger in compression, down along it's length but the minute you put any sideways pressure on it, it could buckle and collapse, especially with a person of more generous proportions and they then go to move. The foot rest would probably go pretty quickly too with body weight applied to it.

Not a problem all input is welcome.
I was going for something like these which deffo are 22mm soldered copper at £155 a go..

The supports look better though

Do like those.... Might have a crack at one myself

 

[daveA66]

These (if it all works out) are for my daughter.
I made her a shelf out of copper pipe and a reclaimed scaffold plank and now she would like some matching stuff!! 4 stools and a table

2m lengths of 22mm copper tube are also useful for ensuring everyone else complies with social distancing whilst at work

Yes, those 22mm stretchers would be much more substantial and give it much more lateral strength by the looks of it, you could also fill the tubes with sand to make it even more robust.
