Came across cold drawn seemless tube with 4.8mm walls. What do you think?

Too light Gra and'll be 'spensive in comparison to CHS (circular hollow section) double or more ús

the 101 and 88.9'll do, I'd have thought, if Mog can't come up trumps with some drill tube !!

You're not exactly ripping rock with it are you

The more I look at it I may be causing more hassle than it is worth, trying to get suitable 100mm tube. I had assumed with the wonders of the internet I would just go on line and order exactly what I wanted with no hassle. It seems more difficult than I thought, so may end up with 100mm round bar just for an easier life.
Can still save a fair bit of weight slimming down the rest of the cradle.

Had a look and the only stuff I have big enough is 120mm OD with a 60mm ID so you could turn it down and still have 20mm wall

Graham,
I have 100mm 5mm wall of cuts (Hyd tubing) but its far to light in my opinion!!

The closest you will get will be 101.6, but id be going with 12.5 wall at least id even recommend going for the 16.5mm wall. When you see them you'll agree

your best bet would be solid bar, for all the weight your saving..... or if you are really weight critical turn the 101.6 16.5mm wall down to 100m o.d

Just my thoughts, hope it helps

Aiden
