Extra Measure Of Caution
One person can safely operate launcher. However, in certain situations, an extra measure of caution is well advise. Dual control trigger restrains over eager participants from launching a rocket, until there is an “all clear”.
Two each easy pull cantilever pin triggers with attached 12 foot long pull strings in two colors.
The red string with cantilever trigger pin is for the person launching the rocket.
The yellow string with cantilever pin is for a safety moderator.
On a count down from 3-2-1-Fire, the safety moderator pulls his/her pin at count of 1. This prevents launch from occurring too soon.
LAUNCH FROM 6 POSITIONS for Safety and Convenience. Trigger housing has 6 launch holes for the cantilever pull pins. The safety moderator and the person launching the rocket may choose any combinations of the 6 launch hole positions for safety and convenience.
Launch Holes are located in 60 degree increments. For example, on an analog clock, that would be 2 o'clock, 4 o'clock, 6 o'clock, 8 o'clock, 10 o'clock, and 12 o'clock positions. A good arrangement would be to position the person launching at 6 o'clock, and the safety moderator at 4 o’clock or 8 o'clock. This give the safety moderator a good vantage point to see that all is clear for launch.
LAUNCH PULL PINS THAT SNAP IN & SNAP OUT.
The safety launch pin has a feature called a "ball detent". It is made from 1/4" diameter stainless steel round rod to resist rust. On the tip of the pin is a spring loaded ball bearing that is raised above the surface of the round rod. When you insert the pin into the trigger hole, it SNAPS into a positive position. This prevents accidental rocket launch due to slippage. At launch, the 4:1 leverage ratio cantilever pull pins snap out of position EASILY for a perfectly timed launch EVERY TIME.
ONE INCH DIAMETER BLACK PLASTIC BALLS at the ends of the launch pull pins are good handles and very convenient for handling and pushing snap-in launch pins into position.
