Similar, but larger than the last.
8 mm ID, 20 mm OD, 70 mm long, 2.5 mm nozzle. Very thick and heavy tube, probably quite an overkill. Wax treated cat litter nozzle and end plug, rammed with conical rammer.
Fused with thin blackmatch glued in place with meal-NC paste.
Hot-melt glued to the strip of cardboard used in the last device. This time the device was mounted much further out from the pivot point.
Didn't make it round.
It just didn't quite have the thrust to lift the rather heavy tube all the way around. Nice long burn and good charcoal effect. If it was mounted closer in the the pivot or counter-balanced, as in a full saxon it would have worked perfectly.
Quite a disappointment that such a stupid construction error wasted such a high quality tube and 2 table spoons of composition. I only have one of these particuarly heavy walled tubes left, but I do have a large quantity of 18 mm OD tubes I made up from frozen food box cardboard, they should be a good replacement. Judging by the total lack of thermal damage to most of the tube wall even normal 80 gsm A4 tubes, that I usually use for my core-burning rockets, would have worked fine.
The video was a bit of disaster too. All in all, not a good start to the evening's shoot!
