Hi, I've been looking at the pultruded tubes and box sections as a want to make a wing spar using them but i want to be able to slide a centre tube inside two others if you get what I mean. so all I need to know really is; will a 10mm od tube slide into a 10mm id tube? or are the tollerences not accurate enough to allow this?

Thanks, Look forward to a reply, Steve.

Thanks for that, I ordered up the tubes.

you were sure right when you said they didn't really need any sanding, although i'm pretty sure that they would have worked straight out the box I literally spent no more than a minute with 1500 wet and dry and they slid together really smooth, thanks for your help so far
