Hello everyone.

Quick question: i've purchased an inert PG-2 rocket and i'd like to make a dummy propelling charge container, out of 40mm pvc tubing. Could someone help me with the dimensions (the overall length) of the charge container?

I guessed it to be around 13-14 cm from this drawing http://en.wikipedia.org/wiki/File:PG-2_rocket.JPG, but i'd like to know the exact dimensions.

Thank you in advance.
