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

Make double sure your preparation and keying of the surfaces is spot on.  Roll wrapped tubes are made around a heavily release coated mandrel and wrapped in release coated shrink tape, so you end up with release agents all over the surfaces of the tube, so any areas not properly keyed simply will not bond with the adhesive.
