Ah, Tata Steel product! Can I ask where did you get it?
I would have chosen their Celsius 355 product instead, which is already stress relieved.

Also, you can't just bolt steel tubes and expect a good joint. The contact surface will be poor. You need to first bond the tubes with something like a steel-filled epoxy, and then bolt.

Hello jarjar. Welcome. To my build log.

As my first post suggests, total novice here. Stress relieved? I'm not sure what that means. I chose this steel box section because it was half the price of anything else I could get my hands on and seemed a much more suitable and rigid material than aluminium. I didn't know different types of box section steel would be more suited.

What is their Celsius 355 product? I'm afraid I did not do much research into the types of steel box section available apart from dimensions. Maybe a bad move on my part? Any comments on this would be appreciated.

Neale, I took a good look at your posts before starting this log and this is where I got a lot of my rigidity ideas from. Although now it seems I have got myself some steel that may not be as good as yours, we will see. I hope the steel box section I have is not going to be a major drawback. If it is then please let me know.

I'm hoping to make a start to the 3D design over the next couple of days and I will post some images of my progress.
