I'm glad you were out of the firing line and you were OK.

Melis, is that account of yours from another forum? The rationale of gas buildup seems to be a good one. I would doubt if it is only pressure buildup from heated air or gas inside the joint. To my mind the amount of trapped gas within the joint should not have enough energy to deploy so much mass at force. I'm thinking it may be that the heat ignites the rubber and/or grease and this causes a fast release of gas propellant, rather like a bullet cartridge.

For safety sake maybe clamp a heavy vise or something on the outer end?
