tub tubes

[will_08]

after making an arse of my tub tubes rp1 etc with a plumbers pipe bender, i then thought an electricians conduit bender would be more suitable,

then.... i thought is there any good reason why i just cant use 20mm electrical conduit for these tubes?

Don't see why not but they are usually galvanised so make sure and remove it in the area you plan to weld. I believe it gives off nasty fumes.

Not sure about using conduit, but I did use a 20mm conduit bender to bend my tubes.
It didn't make a perfect job of them, and flattened them slightly, but it's good enough considering the ali tub is going to cover them.

Thanks for the input guys, i might retrieve the tubes and give them go in the conduit bender.

any input is good as i'm using 20mm conduit some contractors left for me when they did a job, i told them i was building a kit car and asked if they had any off cuts 10 mins later he had to order 2 more lengths and a pack of 6 lengths turned up and he said it yours if you want it. bonus

I used a conduit bender but packed the dies out with some duct tape to make the tube a bit more of a snug fit, It didn't work out to badly;)

Dont suppose using conduit is a problem but dont use the galvo stuff as fumes when welding are toxic. Also galv <zinc> plays havoc when it comes into contact with ally.

You could of course just go buy a length of 7/8' 16-14gauge ERW clean mild steel then you'll have no trouble welding or bonding to it.

true, but the conduit is free!

Im not a glaswegian for no reason :)

I'm using 20mm conduit (Again for free) and have just done my bends today, what I did was cut 4 pieces about 1m long then where it says in the book the measurement BEFORE the bend add a bit extra.
I now have 4 90 degree bends which I intend to join by means of an insert into the pipe and weld fully ensuring I grind the galv off and use a mask when welding.

alternatively buy the ones on ebay :D
