A bit of a seasonal build.
I was asked to make a rocket launcher by a mate for display sized fireworks.
So I thought I'd post a couple of pictures of the build.
5mm x 30mm bar, 25mm x 1mm and 30 x 2 mm tube.
So quite a bit of experimentation on torch positioning
Roughing the shape out, I realise this metal stuff is hugely stronger than wood, so modify the design to massively overbuilt instead of hugely massively overbuilt.
Cleaned off the galvanising
Taking shape
I was hoping to photograph the white zinc plumes coming off the internal surface, failed, but it looked arty so I'm boring you with it anyway.
In case there's anyone new to this malarkey, the white is burnt zinc, which fumes off when heated, and is jolly toxic. Hence the build taking palce outside. The exterior coating was stripped during prep, but the internal galv still produced a huge amount of smoke. The drible in the picture is the bead where I was dialing in the wire speed and was too lazy to clean it off as it's going to be a LONG way from the public...
Ready for action. It's getting tied to rebar sunk into the ground and fired Saturday.
I'm new to this with barely a night school course under my belt, so pointers would be most helpful. Specifically on what setting to use for different thickness and how to play the torch to get a better bead edge.
