I had an idea... I know where I can get hold of some scaffolding poles, and thought I might have a go at fabricating my own HD bumpers...

Question is, are they up to the job? I belive they're 2" OD (standard scaffolding size?) and the plan would be to weld 2 together, one on top of the other, and either cut 'n weld or bend (if possible) to mimick the slight angling back of the commercially available ones - and, obviously, welding on sufficiently sturdy mounting brackets.

Would standard scaffold poles not be large / thick enough to take the required punishment? Or would they work quite well? Has anyone else tried something similar?

And for those who have tubular HD bumpers... what diameter is the tubing?

They're for a Disco 1, btw...
 
When makeing a home made bumper the trick is the strength should be in the design . A lot of folk use to heavy gadge steel and over enginer them.end up with something for a tank.

absolute tosh
Zinc (Galvo) fumes are not toxic at all.
Read the thread in the FAQ section :eek:.

They do give of fumes tho (best to weld in open air) and can give flu like symptoms for up to 24 hours if you breath the fumes alot.
Just clean off Galv where yu intend to weld and use a weld thru primer to protect it short term, if you have to.
 
Whether poison or not its like none Asbestos brake lineings , You dont want to breath that **** in
:hippie:

ok it not going to kill you........ but you will feel ill

why not just pop down to your local steel place and buy the right stuff for the job, scaff tube is not right for a bumper
 
Make it from steel tubing fit it,check it,be happy then get it galvanized. Not that costly. Place near worcester will gakvanize a bulkhead for £50
 
So... wear a mask under me welding helmet then?

Gonna have this issue anyhow, as I've bought boot floor sides from YRM... which are Zintek panels... big fan in the back doorway to aid ventilation, methinks...

'Cos the scaff tube may be coming my way for 'free' ;)
 
Grind off galvo where your going to weld, its going to come off anyway when you weld it and if you weld with it on it will spit and not be as good.
 
my first thought is that it wont be strong enough to take direct impacts, but there's only one way to find out :p plus its a good learning excercise i've gone through 3 light bars so far, slowly making them better :p
 
ive welded lots of galv tube over the years, grind off where yer welding as you would with paint or rust, if youre working outside you shoudnt have any problem with the fumes ... i never have. and have never worn any form of mask for the fumes.
