06:54 Conclusion.

In this video I try some of the ideas presented in the comments from the previous build.  I couldn’t prevent bag to lift overall but interventions which included using a wider inlet and hose, thicker or heavier gauge bag, and a PVC pipe within the drum that equalised the pressure beneath the bag – all combined to made a big difference.

In the final video I install a pressure valve onto the drum.
