Default bubble blowing machine

Some time ago a board member sent me details on setting up a bubble blowing machine for entertaining our younger potential members at rallies. When my computor system suffered a terminal illness in october I lost most of my files. Can anyone refresh my memory on this one ?????

For those who can follow directions without needing drawings, all you need is: a small enclosed squirrell cage, or paddle fan type blower (can be homemade), a small mandrell with bearings a smaller, light mandrell with bearings a wood spool a dozen or so bubble wands some pulleys or gearing various bits of sheetmetal to form a tank, fan ductwork, and a nozzle (brass looks best) a sturdy base, like 3/4" plywood.

The engine drives the first mandrell, which is solidly mouned to the base This mandrell drives both the squirrell cage at high speed, and the smaller mandrell at a very low speed. (I'll leave the exact arrangement, and type of drive, to the builder) The smaller mandrell must be set up a bit above the base. It is fitted with the spool on one end, which has been drilled radially to accept the bubble wands at regular intervals (it will look sorta like a flower when viewed end on) A sheetmetal (or plastic, if you're lazy) tank of bubble soap sits at the bottom of the "flower" (up to about 1/3 of the diameter, so that the wands dip themselves as the mandrell rotates). The exhaust of the fan is ducted (preferably with a round nozzle) so that it blows through the holes in the wands at the top of the "flower"

about bubble machines.. they are great displays but don't do as a friend of mine did and put food coloring in the water so you could see the bubbles as it tends to make people mad when it stained their clothes.. he was a low down dog for a while and still gets a little red around the collar when you mention it to him.. have fun.. jim king

Will, that was way to much information . Let me know what show you're planning on taking that one to, and I'll be going to a different one .

I would be real carefull about using a hit/miss engine exhaust to blow bubbles. When they are not firing, they really suck. If you are running it on cabbage, those tub bubblers are quite efficient. Al

One thing to consider about bubble machines... I spent the weekend at a show playing with the Lehmann battery powered (G gauge RR) bubble car. After a few hours everything within about 4 feet of it was sticky with soap film.(When you go to wash the soap off,things will get extremely slippery for a bit too)
