hi thanks for the info and i dont think buying anything from guys on this forum is going to help much cause im all the way in south africa but anyway im sure i can find it somewhere but tell me would you know what is a good thickness for the wall of the tube wall

Edit your profile so people can see your location. Then people can give you suitable replies.

There is another guy on here from ZA, maybe he can help point you in the right direction. Just rembered his user name - Landlocked

IIRC the wall thickness is in the book. Can't remember it off the top of my head, will have a look at my receipts. Just checked receipts and it's not on there. I think it is 2mm off the top of my head. Book is in garage and the weather is miserable, so I'm not going to look

sorry i ment see i dont see it in the book

Ricky, my steel merchant has offered to order the seamless tube for me. Not sure how much we need, but maybe place our order together? I'm in Kempton Park.

That's a fair point. I've just been down to my garage and I have a handwritten note in my book, it's 2mm wall thickness.

A quick search of the forum using the term "seamless" brought this up though - link to question on seamless thickness.

The answer at the time, from Chris, was 2mm.

Hope that helps, and if you are anywhere local to Landlocked order the steel together, you 'might' get a better price, then you can have a brai when you pick it up;) (I have a load of Saffer mates - Bring and Brai's all summer long:D)

The 25mm diameter tube is 2mm wall thickness, and the 19mm tube is 1.5mm wall.

Hope this helps in your search.

Kind regards

John
