Actually, so far, NOT burning down the house!
I sealed the speaker-end of the tube properly (ruben's tube; fire and sound; see previous posts) so it didn't leak; discovered that I was getting bad connections to my sound sources (using the laptop works fine); and did another test fire last Tuesday.
Oooo, the pivot joint thingies in the OTHER end of the tube leak under pressure, too. I sealed them on the inside, but clearly not boldly enough.
So I smeared the OUTSIDE of the joints with silicon on Saturday wrapped that in duct tape, and then wrapped THAT in electrical tape (to hold down the duct tape, which has terrible glue; what a horrid brand).
Sunday, then, I did a THIRD test-fire.. no leaks! And I have LOTS of compression on the speaker; I can blow the flame out with a slight twist of the volume knob.
NEXT Saturday, then, I'll have some interested parties over and we will experiment with it more....
Fun!
