Reynolds Tubing Source in Sydney

Post by Rob » Wed Feb 24, 2010 4:09 pm

G'day Guys,

Can anyone point me to a decent supplier for Reynolds tubing in Sydney?

So far I keep coming up with cold drawn welded seam and I don't plan on betting my life on a welded seam cage.

Cheers,
Rob

Thanks Stayt'ie I'll give them a try.

I can get chromo down at Windsor but they don't carry Reynolds.

For reference, cold drawn welded seam 1 3/4" 0.125" wall was $26.50/m or $175 for 6.1m length.

Cheers,
Rob

I rang the number you gave me Stayt'ie (thanks again) but it diverted to the local mob so nooo Reynolds tubing. :?

Anyone else?

Cheers,
Rob

I got onto a company called Racetech at Castle Hill.

Cold drawn seamless tube, 1 3/4" X .120" wall $36.55/m lengths vary but are all around 6m making a length $220. Apparently it's not much called for and they only have 2 lengths in stock.

They do chrome moly but it seems my TIG money has just become seamless tube money. No TIG=no chromo.

I'll keep shopping but doubt it's going to get much better.

Cheers,
Rob

Are you building a drag car?

If you ain't you're wasting your money on CroMo.

This isn't directed at you alone Rob , it is a very common question in LSR , the generally accepted suggestion is mild steel,softer, more forgiving for welders and heavier which is good for LSR

Just for the record our whole car, cage and all is built from black pipe......the lengths are very short.If you are building a cage with long spans then you definitely want seamless, otherwise it's an argument that could go all day but all road car safety systems rely on deform-ability.

Picture this, we bent the pipe and it didn't split..........if the car is subjected to the force put into each bend( that's two tonne and remember they are all stitched together now) AT THE SAME TIME....it's not likely the driver would survive unscathed.....brains and internal organs can't hack that sort of stuff

If you have a ticket and are experienced in designing and building structures using CroMo , do it, otherwise you may end up with a structure that has no greater strength than one built from mild steel, will cost more and may be compromised due to stress and embrittlement caused by the welding.
...few understand what I'm trying to do , but they vastly outnumber those who understand why..

G'day Doc,

No chrome moly in my future mate and I need to find a cheaper source for seamless 'coz I still want a TIG. :roll:

I got the heads up on a mob that sells "seconds" that may or may not prove fruitful. Not seconds from production, scratch, rust and dent type stuff.

Cheers,
Rob

Still looking for seamless tube for the cage, the two lengths I'd supposedly found are not seamless.

I rang a couple of larger cage manufacturers in Sydney and they are saying I'll be lucky to find any in Australia and most cages now are built with CDW (cold drawn welded).

I'd really like to use seamless for at least the main structural members but this is fast becoming a hold up for me.

If anyone can offer a solid lead I'd appreciate it, even interstate.

Thanks,
Rob

Thanks Ross,

They have a Sydney branch so I'll give them a call on Monday. Not too far from me either which is nice.

I'll let you know how I go.

Cheers,

I brought some annealed hydraulic tube from Van Leeuwin in Perth for my cage structure. I have not used it yet and have had the tubing poo - pooed by a guy that builds formula vees on a regular basis. He recommended that I visit Searle Race Equipment located in Welshpool WA because he says they carry a variety of tubing types and in sizes for every occasion, they are reasonably priced and good to deal with. I have not done anything about it so I do not have personal experience with them. I'm not 100% convinced that annealed hydraulic tubing is not the way to go. Any thoughts on that anyone? There must be people like Searles in every state but if not call them on 08 9358 0050.

http://www.walkerchassis.com.au/

Walker Chassis is our local roll cage maker (SA)
They sell cages in kit form if thats any good to you.
He works out of his shed and makes some really nice gear.
I bought a flat pack cage from him for a Torana i did up a few years ago and it was an exact fit, all the bends were in the right spot and all pipes had a bit of green on them.

I think any annealed pipe will be too soft for a cage, its annealed to make it easy to bend. :wink: Not what you want from a roll cage.
It might be easier to manufacture but the end result might not be strong enough.
From what i know cages should be built from seamless tubing, steel on chrome molly. Ive also heard that cage tubing is a special diameter so it can be measures to check that it is built of the right stuff.

Thanx
Dave

Seems to be a lot of conflicting info here.

What's the go? Does the tubing have to be seamless? Given the difficulty some people have in sourcing the stuff it's obvious that many roll cage builders aren't using the stuff. Does it really matter?

As James (googles) said, at some point the human body just can't handle the shock loads involved and I think that point would come before a difference in seamless or welded tubing was worth worrying about.

Yes i know its CAMS but they have a min requirement for a reason.
If you build an inferior cage and the worst happens, then the safety crew has to cut a mangles mess of pipe out of the way before they can get to you.
Have a look at the V8's they have some big high speed crashes into immovable objects and generally walk away.

A quote from CAMS http://www.rollcage.com.au/rollcage.html

"The CAMS/FIA regulations stipulate exactly what material specifications are required to be used in the construction of a Roll Cage for motorsport use. There are two main options available, and largely depend on your budget and individual needs.

Cold Drawn Seamless (CDS) high tensile steel tube (350MPa): The most commonly used material for Roll Cage use, offering a great affordable ROPS solution. The design of a ROPS with this material only needs to comply with the standard design principles as published in the CAMS regulations (Schedule J), to be eligible for registration needed for Australian competition use.

Cromoly (650MPa): The more exotic of materials, with a great benefit in the weight department, being significantly lighter than other materials due to higher yield strengths allowing the use of thinner wall thickness. However, this material is harder to work with and requires more time in the fabrication process. It is also the more expensive option for a ROPS, with a higher material cost, requiring a lot more intricate design to satisfy CAMS/FIA regulations. Cromoly also requires a designated and independent ROPS specialist engineer to assess and sign off the design before CAMS registration can be given. This additional engineering consultation is not cheap and adds to the overall cost of installation."

Thanx
Dave

Thanks guys,

DLRA Rules only specify minimum tube diameter / wall thickness and mild steel as the material. (I'm not interested in moly).

I wouldn't be running annealed tube for a cage either. 350MPa CDS is what I'm looking for.

Seamless tube is my own preference. Either a lot of people are getting duped when they buy a cage or ???

If I do no good here Monday I'll give Walker a ring. They list Performance Metals on their website though and they don't have any CDS. Thanks Dave.

If I can't find it locally soon I'll bring some in myself from the US in October but that will definitely kill me for next March. This is one car I won't be rushing to assemble.

Cheers,
Rob
