Making a Fountain from a Thread Cone
This was inspired, in part, by a Passfire message by John Reilly. Thanks, John!
Composition used was RP with +20 Titanium and +16 Charcoal. Don't tamp sensitive fuels - press them instead
These cones are from eBay and were thread cones. They have large openings so they need to be necked down. The cone on the left is doubled up (two cones glued together). That is what we will use for the final product.
Make a mold from some cement and a container (in this case a piece of scrap PVC). Wrap a cone in plastic tape and/or grease it.
When the cement sets, release it. The mold isn't necessary for charging the cone but it acts as a handy holder for drying
Nose piece. put the cone on this, tamp in 3/4" of clay, add comp (press if it is a sensitive mixture), add backing.

Some wood tools to press with - these are not horribly precise but note the middle tool has a hole to accommodate the nose core.
Bottom of cone after pressing composition in. It is sealed with a fiber board seal and hot glue (a nice use for that mold we did earlier is to hold the cone while all the glue sets).
Click on the image and see the cone burn out quickly! ..but even with that it was three times as high as the $4.00 commercial version. Just needs a bit of tuning .. yeah.. that's it.
A Whistle Fountain
Here are five 5/8" whistle rockets and two 1.4g mortars. The mortars are fused to pop just as the whistles finish. The whistles are 'left-overs' from the whistle tests. See: rockets/whistletests.html
The mortars and whistle mounts are securely fastened to the heavy base with glue and screws. The whistles are set in at an angle and hot glued in place. The whistles are quick matched.
Click on the above image and see the action. The quick match popped when it ignited and I jumped out of my shorts!
Borrows Heavily from John Glasswick's Gerb Formula Article
Do not tamp any of these. You can hand press them damp and let them dry (takes a few weeks) or you can press them in a hydraulic press. Mr. Glasswick hand presses them dry and they seem to work for him - I would be uneasy with that - especially if I was mixing different effects. Start with chokes that are 1/2 the diameter of the tubes for these mixes.
