Not really much gas. You would be suprised how fast it heats up with a large tip. Gas is also not a problem when you use trade schools gas. :twisted:

The oxy trick sounds good but if you are doing a cams spec cage or a cage that is ment to be strong, you cant heat up the tube as this will anneal (soften) the tube. :cry:

That's what I was thinking to myself too.

ANTT Get your dies from Queensland Trade Tools. About $80 for a 32NB and I also have a 25NB but forgotten the $$.

well, finally bit the bullet and ordered one of these today

trade tools reckon they don't carry them anymore, so he sent me round the corner to blackwoods (didn't even know it was there till today). ended up being $107.80 and it has to come from melbourne so will take a week to get here

i ordered the one that had 32mm next to it so hopefully its the right size

yep 32mm is the one. that is what i bent all the shit on my buggy thing with.
onesteel was the cheapest i found for the steel. $8.50 a metre for the 3.56mm wall seamless. the onesteel product number is PS6-422-36-6m

cheers wendle, good to know i could build a buggy with the thing if the need ever arises :twisted:

i bet you've got monster arms now from using the hydralic jack doing all those bends for the buggy frame

I had the same problem with the rollers denting the tube.
solved it by buying some 75mm od actetyl rod from plastics supplier and machining new rollers with the correct size depression for the tube being bent. no more dents.
material cost ~$30 for 300mm, enough to do two rollers.
machined them on a wood lathe.
have done quite a few bends and the bender frame base deforms and there is no damage to the rollers, so the acetyl material seems to be a reasonable choice.
I'm using dawn formers in a cheapy bender, both from a mans toyshop in Rockhampton.

Cheers
Daryl

Thanks wendle .. thats the kind I thought you were on about .. but it;s better to ask a free question befroe I lay down the $$$ and find I have some unworkable bit of crap ..

well, got the die this morning from blackwoods, should be putting it to the test on saturday

Post by **antt** » Wed May 12, 2004 11:54 am

a couple more, the gap is about 43mm i think

Post by **Wendle** » Wed May 12, 2004 12:46 pm

you need to make a little adapter if you are using the red chinese bender.
25NB schedule 160 just haapens to be a perfect fit, which was cool, cause i have heaps of it. :cool:

you just need something about 33mm OD, 20mm ID and about 25mm long.

yeah, was looking at that wendle, might have to turn something up on the lathe

buy a stick of the aforementioned tube. you will end up using it for something, it is good for steering links and shit..

well, used this thing on saturday to do my rear bar and it works farking awesome, except for the dents in the pipes, will have to figure out what to do to fix that

we did a bend that was actually passed 90* and it didn't deform at all. like the others have said, these things are the way to go for a cheap bender. best $100 i've spent

Post by **N*A*M** » Sun May 16, 2004 10:09 pm

so did you make an adapter for the die to the ram end? make me one too and post it to me :lol:

If i got 1 of those Super Cheap benders and used this set up will it work?

move the rollers outwards, so the die isn't pushing straight against them.

Post by **antt** » Mon May 17, 2004 7:39 am

wendle, we had the rollers as close to the die as they could go without hitting it when it was pumped up, i'll give your idea a try

NAM, we didn't bother with an adaptor for it, once there was a little pressure on it, it worked fine and didn't move

carl coight, yep these things work with the supercheap benders, thats all we used on the weekend

That's great, thanks for the reply.

The Dawn dies are to suit Nominal Bore Pipe so I don't know how the sizing compares to DOM....
