Thanks Lloyd. Nice to have a comment from the person that actually created the original composition. :)

 

My concern is if my home-made sgrs will foul the composition. At this point it looks good.


I just start the conversation - someone else has to question them.

Made some copper benzoate, rolled some small 6mm ID tubes for small reports, + got my 15mm and 22mm comet molds and rods from the shop.

Nice pyro work ahead. Yeepee.

In addition to ordering some chems that should be delivered on Saturday, I also saw this and immediately thought "that is a poor way to make stars":

That gives new meaning to really getting in there and breaking up the cores.  


Just so you guys quit asking, here is the link to the old forum. http://www.xsorbit2....forum/index.cgi

The sky is my canvas, and I have 2,113 pounds of powdered paint in the workshop.

But Mumbles, how else would you test the torque of your star roller and get a real feeling of how it to turns?

Related... Making and assembling pulleys to get a reasonable speed in the rolling machine from a sewing machine motor. Two stages reduction since I can´t make a big enough pulley.

Made what for me is  good sized bunch of 3/8" and 1/4" stars using the tabletop roller. Yankie's Purple using phenolic. Went very well once I got the cores right.

Yeah... I'm getting used to 'drudge work' myself.  We had storm damage to our barn/shop, and all the important damage was on the pyro-shop/machine-shop side.  So, I've spent (now) 12 days on the roof, replacing old, rusty lead-head nailed roofing with new screw-attached metal.

 

It's a slow go, and HOT (93F today), but coming along well.  Eight more feet to go, and all of the West side's 50-year-old nailed-on metal will have been replaced.  It was only 5000 sq.ft.of goods for the West side.  The east side is the same size, but will be easier, because there's nothing there that can't stand a leak or two, so I can take it at my leisure.

Progressed on a 6 shot firing rack for rockets, 10 seconds timed with a 60 cm main visco. The system is designed that it'll not be necessary to attach each rocket visco fuse to the long visco , which is so time consuming before the show...

Visco and also Mantitor Igniter cord can be used to advantage on timed displays.

 

We make multi-shot plates that use both, and also use (sometimes) just loose BP in the fuse groove (for more-or-less 'instantaneous' ignition of all the tubes).
