JohnT talked about timing for a 7 insert shell so that it resembled 'Shave and a Haircut' on Passfire. He fired it in a test and I asked about his timing. Here is his post:

Danny, I just wrote it out in musical notation using 8th notes. That gave me 1,3,4,5,7,11,13 for the intervals.(just tap your foot and think 'pop' at the first, third, fourth, fifth,... 13th beat and you'll see what I mean. Now my fuse burns about 2.5 seconds per inch and I wanted the tune to last about 3 seconds . The interval was from 1 to 13 so I tripled it. 1,3,4,5,7,11,13 became 3,9,12,15,21,33,39 The interval was now from 3 to 39 which represents thirty six 32nds of an inch (right around three seconds). That's what I used. It's fun putting together music, math and pyro . JohnT

I made a couple of them up for a meet at Vinton using cap plugs. I used about 5/8" as the starting fuse length. Here is the first one...

Here is a more robust version - made with 5/8" inserts:


Made me smile! I used flash for the first, sixth and seventh reports - BP for the ones in-between.

Timing in 32nds is: 0, 6, 9, 12, 18, 30, 36   So, start at whatever delay you want after the burst and add those numbers onto the length of the timefuse (in 32nds although 24ths or 20ths would probably work).

It is important to use very reliable and accurate fuse cutting and priming.  The burst for each salute should be very easily lit... Very hot BP or a chlorate flash with antimony sulfide seems the most reliable. See the cap plugs header for more information.
