just recieved my saftey devices roll cage with all the fixings.

Question is weld the spreader plates that came with the cage to the shell or make my own that are bigger and use the plates that came with it as external washers ?

dont need to double plate and would high recommend not to you,only need to plate inside to stop the feet pushing through in a accident so dont use two plates only one.when i fitted mine i made my own which were alot bigger cant remember the size but have a look in the blue book of regs as it will be in there.but the safety ones are more than adequate.  dont forget to weld through primer before welding and practice on a peice for committing to the real thing as it only one shot deal if im honest and it got to be a decent weld a full seam all the way round,none of this gasless crap.if your not a experienced welder get someone who is

Seam welding I do not have and issues with. I made some bucket seat supports which are seam welded in

Blue books 150mm squared I think. By 3mm? (I think).

I have the blue book as pdf going to read it. I am 100% sure on the 3mm that's why I bought two big sheets of it.

according to the MSA blue book for 2015 it says spreader plated should be 120cm squared. how can that be right thats huge or is it a typing error ?

11x11cm? Just over 4" a side.

that makes sense. but 120cm doesn't even if it was the total size of each square thats 30cm a side lol 

[bigrob]

If it was 30cm a side that would be 120cm perimeter not area :) area would be 900cm2 if it was 30cm a side

120 square centimetres, not 120 centimetres squared (not that your 30cm calc is either of these!)

 

12cm x 10cm = 120cm2

Yep makes sense to me this morning after sleep lol. Been a long week so far.

Thank you for correcting my dumbness haha

Or you can just use the ones sd provided doesn't really matter providing you have them there
Thats ok then regarding welding part
Plates aren'tthat big when you consider half of the plates are bent in half but yep look massive when marking and cutting out

The ones that came with my cage were a bit smaller than msa regs size. So I got some new ones made up, they are a bit bigger and will go up the sill slightly to give a little extra strength.


I was thinking the same as you about putting some spreader plates ok the outside to use as washers but now I'm not so sure

[James_eaton_thewholething]

So I made these probably a bit over kill on the front section but if going to do something may as well over do it especially when it's safety involved

[morley]

Nice work, what did you use to bend them?
