Jamie_grieve Posted August 3, 2021 Share Posted August 3, 2021 I need to start the cage on my forest rover buggy thing and although I won’t necessarily be entering it in MSA events I think it’s a good place to start in a feeble attempt at compliance.. I was looking for specific information on the cage material requirements but the only thing on the whole MSA site I could find was in reference to single seater racecars. Can someone please point me in the direction of said tomb of knowledge? I remember much of it was like the old ALRC green book but I was keen to see if there has been any updates in the last few years since I ever saw it. Specifically for anyone remotely interested, I was looking at using a sleeved rear hoop with a 50.8mm tube inside a 60.3mm tube probably using S355 but I’m totaly open to suggestions. Regulations for truck trials might be more applicable if the MSA covers that too nowadays? I’m wondering if I would be allowed to plug weld it in particular. https://www.motorsportuk.org/resource-centre/ That’s the site I was looking at but can’t find anything. The last entry on this site about it was in 2018 and even going back years, there’s only references to it but no links. Thanks for any input.

Whilst I have you there, I didn’t want to mess your thread up with silly questions and comments but can you remind me please if your 404 half shafts are 8 or 10 spline? I’m thinking they’re 8 spline but I forget as I work on so many different things. The reason I was asking is that the Simca Sumb ones are an almost identical size but are 10 spline.

Stellaghost Posted August 3, 2021 Share Posted August 3, 2021 I don't believe you know how to mess a thread up........ But to answer your question they are 8 spline regards Stephen Quote Link to comment Share on other sites More sharing options...

Chicken Drumstick Posted August 4, 2021 Share Posted August 4, 2021 Dunno if this would be any help. These are the ALRC roll cage regs, we are MS UK (aka MSA) regulated, but as a general rule our roll cage regs are a bit tougher. https://www.alrc.co.uk/stylesheets/downloads/Roll-cage-regulations.pdf Quote Link to comment Share on other sites More sharing options...
missingsid Posted August 4, 2021 Share Posted August 4, 2021 Is there anywhere on the forum this can be put for reference as it is very useful particularly as a PDF or has it already been put in the tech area? Quote Link to comment Share on other sites More sharing options...

I tried a few different search queries but nothing came up. It would definitely be a handy resource but it would need kept current and up to date to be useful, especially the EV regulations which will probably see a constant stream of updates for the next few years.

Can you give me a page number or link to the relevant section please? I seem to only be able to look at individual sections. Trying to download the whole blue book on Safari or Firefox doesn’t work either on the computer or ipad. Quote Link to comment Share on other sites More sharing options...
Jamie_grieve Posted August 5, 2021 Author Share Posted August 5, 2021 That’s the error message I get when I try to open or download the whole blue book or the section with the contents: I hate things like this that should just be easy and work yet don’t. I almost came a cropper as not all the dies for the JD model 32 have a bend radius over 3 times the radius which is required in the ALRC regulations that Chicken Drumstick posted above and I’m sure were the basis of the MSA regulations I’m looking for.
