More progress on the prototype.
Brackets the hold on the second flare.
Lots of brackets:
My expert assistant (aka dad) drilling:
This one has been a team effort, with four involved this time.
Plugs for the ports:
The ports didn't come out quite right. They were machined by CNC but I made a mistake with their location, a mistake related to rushing! So I've had to mark out the corrected port locations.
Mouth flare termination:
Drilling new ports - not exactly a job for the average power drill! The table needs to be large and a drill press probably wouldn't do this, because they would all be too small. The shop smith is ideal here.
