Last weekend I was at the Boomershoot site doing some preparation for Boomershoot 2020 (May 1st, 2nd, and 3rd). Among my tasks I created a new site for the opening fireball. The opening fireball for Boomershoot 2019 was a little too warm for comfort. So I found a location further away from the spectators and built a sand platform similar to the one for Boomershoot 2019. It also happens to be in a location with much better visibility from the web cam.
Had you been watching the Boomershoot Live web page you would have seen this as I worked on it:
The sand platform serves two purposes. One is to raise the explosive targets high enough they can be easily seen by the shooter from a safe distance over the grass and ground. And the other reason is safety. Many years ago the site had farm buildings on it. Every once in a while we find scraps of metal from old machinery and things like door hinges. Making craters with explosives in this soil risks discovering such scrap metal in the form of a projectile. Putting the sand below the explosives eliminates this risk.
Another task I worked on was replacing the air filters at the explosive production facility. One of the reasons we had excellent detonation rates this year was the quality of the KClO3. It is much finer than than what we obtained from our previous supplier. This had it’s drawbacks as well. The three little air cleaners were overwhelmed by all the dust in the air. Here are the filters:
I think I need a better means of dust control for next year.
Does it need to be any more complicated than some box fans with HEPA furnace filters taped to them? Release your inner MacGyver!
That sounds like a great idea!
