Heres my first.
A 3" by 1" chamber made of DWV pvc
A 2" by 2 1/2" barrel made of SCH 80 PVC
Electronic BBQ ignition (my friend thought you didn't have to wire it back to the ignitor, it took us a week to figure that out)
ABS end cap and ABS reducer
Glued together with only the cheapest epoxy and hot glue
