Preparing Racks, Part II

A welcome drive-by sight last week, was running low on scrap wood.

Rack prep continues, though I'm well ahead of schedule with just over a month left until the show. The focus is now primarily on items that need support or their own rack assembly as opposed to being mounted directly to a pallet. Items that require this are typically fastened / secured in one way or another to a piece of wood that will in turn be fastened to the pallet prior to wiring all events up.

There are multiple ways of doing this, examples of which are pictured.
 
Depending on the effect, and at what point in the show it will ignite (and whether it will run in tandem with one, two or more other effects), spacing and angles must be considered. Spacing for the visco run, and angles depending on what the effect is. Most of the items being fired simultaneously are fanned to occupy as much sky space as possible.

If the plan is to have true simultaneous fire, the racks are wired up with visco, wrapped in tinfoil and stored for now. In some cases, some delay is desired so mixing visco speeds is needed - an endeavour I will undertake in the near future.

Six mines were mounted on angle scraps to a 2 x 8 chunk, which was attached to a small 12-shot Sky Rocket with Report rack.

36-shot fanned Air Bomb rack was built by pre-drilling cavities and pressure fitting the tubes (see the Rocket Attack post).

An 8-shot "Shotgun Shell" rack. Drilled right through this time, interestingly the plastic bases mimic real life shells in that the very bottom diameter is larger than the bore, which helped here. Glued the bases with PL before placing the charges back in & wiring.

Twenty four Mini Air Bombs. Didn't opt to fan this rack since the desired effect is strictly for the noise, and a separate wide angle event is planned for the same time slot in the show.

Two angled Angel Wings barrage tubes fastened to a vertical plank with zip-ties. The plan is to fasten the plank with screws through the underside of the pallet. 

More zip-tie action; seven Asteroids tubes angled 10 degrees apart, this rack will be fastened to two vertical posts sticking up through the pallet stringers, each tube's base will be touching the pallet to ensure none escape from blow-back.
