Hi , 
I'm just about to connect 2 half metre lengths of 32mm ID CF Tube using a 300mm length of 28.5mm ID CF Tube inside .
I'm going to use PT326 , but what i want to know is how much of the Structural epoxy to use to make it solid into one piece,
also what type of preparation do i need to do on the tubes .Is it just on the inside of the 32 mm or do i need to sand the outer surface
of the 28.5 tube .
Also any tips on how to get at least 15cm down into the tube to sand ?
Bit of a newbie at all this .
cheers M

Acetone. I'd give it a wash with soap and water first, then wipe it all down with acetone. Then scuff the surfaces up really well, followed by another heavy wipe with acetone.
