I anyone gets my drift.
Thanks.

Strange, I had to post this twice. Hope this one will work.

Anyways... here you have your answer: 8.2° instead of 10° from the vertical axis.

Black lines on the drawings are the middle axis of the main hoop.

Hope this will help

Thanks, and sorry if you have had to post this before but it's very useful, and thank you, talonmotorsport when I work out what I need in terms of extra height I will PM you about possibly making a roll bar up.
Sorry to keep going on about it, is there a minimum distance your head should be from the top of the roll bar.

Not you fault Davey, no problem, I just posted it a first time yesterday, and checked one or two hours later, and the post was not there any more.

Does anyone know if there is a reason for using 3 different tube sizes for the roll bar?
Couldn't it all be done in one size?

I've only got two, roll bar in around 51mm and cross bar and stays about 40mm.

I think one size would look to chunky on the supports.
But it s up to you as it's your build

I've done the same as Landy and used two sizes of tubes.

I suspect three sizes were used originally because that's what Chris happened to have lying around! It was built on a budget afterall

How about the whole thing in 42mm?

I was thinking it would be more equal. I can't find any pictures of anyone doing this but may give it a try
