yoeddynz Posted January 1, 2013 Share Posted January 1, 2013 Just gentle curves. Say a peice of 40 or 45 mm OD tube- 3mm thick maybe. About a60 degree bend Otherwise anywhere cheap to buy bends? I have tried ullrich and expensive! Need six. Quote Link to comment Share on other sites More sharing options...
craig_b Posted January 1, 2013 Share Posted January 1, 2013 i know autobend here in chch can supply bends or bend up what you need in alloy, unsure of price now, sent them a mild steel copy of what i wanted and they lasered it and seny back as one piece and dont remember the price being outrageous Quote Link to comment Share on other sites More sharing options...
evil_si Posted January 1, 2013 Share Posted January 1, 2013 Tube bending, they are in auckland thou Quote Link to comment Share on other sites More sharing options...
sheepers Posted January 1, 2013 Share Posted January 1, 2013 yea tube benders here in AK have all that stuff on the shelf. they also have a bin of "setup" bends that are random angles. they do cash only, minimum charge is 45$ but if you rat around in the setup stuff you can get more aluminum bends than you can carry for 45$. you want i should go see them? i suspect they will be back at work either the 7th or the 14th.

Stu Posted January 1, 2013 Share Posted January 1, 2013 We have a CNC roller at work that we roll up ali tube for the 3ski bike frames etc - if you get really really desperate I can try teach myself the program and roll some for you.

yoeddynz Posted January 2, 2013 Author Share Posted January 2, 2013 Cool. Cheers fellas for offers of help. I like the sound of looking through piles of bends and taking away many for little pingas. I might see if local exhaust place might bend tubes when they reopen otherwise I'll ring tube benders. Oh- and where's a good cheap supply of steel exhaust bends suitable for headers? I'll go and look on tm now.... Quote Link to comment Share on other sites More sharing options...

evil_si Posted January 2, 2013 Share Posted January 2, 2013 Chase are good but dont do aluminium, Tube bending actually works out cheaper for bends, but its either bank deposit or cash, no eftpos or credit card facility Tried auto bend for a couple of bends and a donut and i nearly shit myself, they were over twice the price Quote Link to comment Share on other sites More sharing options...
Truenotch Posted January 7, 2013 Share Posted January 7, 2013 Ullrich usually have alloy bends on the shelf too. Quote Link to comment Share on other sites More sharing options...
eke_zetec_RWD Posted January 7, 2013 Share Posted January 7, 2013 If u but tube get 1.5 inch od and then someone with a good cage bender will do a deacent job Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted January 7, 2013 Author Share Posted January 7, 2013 Cheers- yeah I went into ullrich in nelson- handily over the road from work. They showed me some bends but before I got excited they explained that one bend cost more than a whole length in the equivalent size! Inlet manifold making might be put on the side as it looks like I might yet be able to use the fraser manifold. maybe.. but still want to make a manifold at some point soon.

Stu Posted January 7, 2013 Share Posted January 7, 2013 If you can pin down part numbers for the bends I can price them through work as we have uber uber discount with Ullrich (Boss is mates with Gilbert etc) Quote Link to comment Share on other sites More sharing options...
rwd_mayhem Posted January 8, 2013 Share Posted January 8, 2013 The problem with bending aluminium is that it work-hardens over time so most of the time stock lengths you get from Ullrich etc will just snap straight away when trying to bend it. If you don't have any luck give me a PM as I work at Autobend and should be able to help you out with something and I hope we would be cheaper than Ullrich since we actually supply them with various sized bends. 1 Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted January 8, 2013 Author Share Posted January 8, 2013 Oh sweet both stu and mr mayhem. I'll get the sizes and codes of the particular bends I looked at ullrich. I think they were 90 degree bends in about 40 or 45 mm ID. But I'll check. I need to see how big I can go as I want to build a manifold with pipes that crossover- too big and they will clash.

rwd_mayhem Posted January 8, 2013 Share Posted January 8, 2013 OK, our sizes around there would be 38.1mm, 41.3mm or 44.5mm OD (sizes that fit our tooling) Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted January 9, 2013 Author Share Posted January 9, 2013 Cool. My local ullrich is still shut anyway. Slackers. I'll do some measuring over weekend. Cheers. Quote Link to comment Share on other sites More sharing options...
yoeddynz Posted January 12, 2013 Author Share Posted January 12, 2013 Ok. Gonna continue on with making inlet manifold. Mr mayhem- what size bends, centre line radius etc, can you get in 45mm ID? I'm looking for some 90degree bends. Cheers. Quote Link to comment Share on other sites More sharing options...
