OldMarine Posted September 18, 2017 Share Posted September 18, 2017 Not enough pressure on the comp more than likely unless you failed to use a support and then it could be an expanded tube. Please give us some details. Link to comment Share on other sites More sharing options...
Josh1986 Posted September 22, 2017 Author Share Posted September 22, 2017 I did not use a tube support I also think I did not put enough pressure what is recommended for 1lbs rockets? Link to comment Share on other sites More sharing options...
AustralianPyromaniac Posted September 22, 2017 Share Posted September 22, 2017 (edited) I did not use a tube support I also think I did not put enough pressure what is recommended for 1lbs rockets? This is a handy document The kind of pressure required for whistle is so great that without a support it's more than easy to blow out the tube so you likely didn't use enough force.
