The Ammount of Horse **** spoken on this forum never seems to amaze me!
hope you never have to put it to the test then.scaffold tube no good for rolcages.you need seamless tubing.i know its a lot cheaper but you cant compromise on safety
I do hope you never need to test it although, "Scaffold tube is no good for rolcages. you need seamless tubing" is absolute Bollix!
Hook what makes you think its no good?
Reasons?
Scaffold tube is Red Band that has been Galvanised.
Scaffold tube if up to scaffold specification is actually above the required specification for roll cages for competition use as a material goes within many organisations including MSA and ALRC for some speed events including comp safari.
Building a recognised and certifiable cage is the biggi. The material is up to it. even if the cage design is not!
There are some issues when building using red band and indeed blue band (slightly less spec but still acceptable in many forms of motorsport). The bends must be bent in such a way as to not stretch nor compress the seem. I.e so the seem is facing forward or backwards or at 90 degrees to the bends in the cage.
Yes you can go CDS if you want to pay mega bucks for the material or indeed somone to make it for you on their mega expensive machine and if you do not intend on rolling over too much. I have seen CDS cages wrecked at Comp Safari's where another heavier competitor in a red band cage has been towed onto its wheels and taken back to pits only to drive again the very same event as the cage has not bent or even been deformed unlike the CDs cage that was cut out and scrapped before the next event.
The main advantage of CDS is that it is lighter and therefore more desirable for the racing boys. Scaffold tube if up to spec and indeed built to a recognised spec las with Redband is very strong very suited for CCV trials due to its stiffness and general overall toughness. I have just got a CCV motor built over 12 years ago with a certified cage with redband and I imagine its been over a few times in that time still no mark on it. I very much doubt a CDS cage would hold up to so much abuse. By the way the vehicle I was told was also comp safari'd for a while.
For roll cage specs see the link on my next post. Like I said before I would only build a cage if it met latest regulations for comps as the extra time and effort involved to make it certifiable is worth every penny when you come to wanting to have a go at a comp and know you will be safe if you do go a bit furthur that you really want to.
,used to get the evo cages in kit form from this place
