Random Rushing - Flame tube

Flame tube 

okay so number 2 was the custom 8 ball but I don't have any pictures for that yet. So the Flame tube music player is basically a real life frequency graph. I am not really doing anything different with this one just using it for nice visuals.
Basically you take a pipe drill some holes spaced evenly apart, cap one end. Attach a flexible rubber membrane to other side of the tube then attach a speaker the diameter of the tube to the membrane. Then you fill the tube with propane (or other gas) and light. When the music plays the flames vary in height based on the frequency of the music. This is based on an old school physics experiment to show standing waves. It is also known as the Ruben flame tube, named after H. Ruben, who published the demonstration experiment in Annalen der Physik in 1905.
I plan on building a fish tank like cabinet with wheels and a glass top. The cabinet below will house 2 speakers 1 receiver (it blew the right amp last year) and the propane. The glass enclosure at the top will house the tube (no top).
I figured music outside in the afternoon would have some nice visual effect while swimming in the pool. Also would give off some nice heat to warm up to if need be.
The wife is afraid of fiery explosions but the likelihood is low plus the pool is right there to put it out if need be.

Okay some of you may have seen a picture of my old version. It worked, I cut some wood, some aluminum, and acrylic but it lacked stability. The cutouts at the front caused the frame to flex under high stress and/or speed causing my cuts to be out of line.
I just happened to have laying around a giant box made from bosch extruded aluminum (it was borrowed from previous employer when I left). The box was originally going to be a giant terrarium coffee table but the wifey was not happy about the idea and it did seem like a lot of work. Anyways it looked like a good replacement frame. Well it ended up about one inch to short in the X direction so I ended up with a compromised hybrid.
It is unbelievably stable now. I have yet to attach the spindle motor yet because I am changing from the dremel to a cutoff saw thing which will increase my cutting power exponentially.
Another drawback to cutting was excessive heat so this version has a pump to squirt liquid at the bit when cutting.
Also new will be limit switches which I had before but never hooked up, this should allow a stable home position and allow repeated work as opposed to one offs.

Alright, I started this blog for a running tally/list of my build projects. It seems that I am always working on one thing on the other. My list seems to be ever growing since I donít like to finish things. Currently on the list are:

1. CNC Machine (rebuild)
2. Custom Magic Eight Ball (this is actually work related)
3. Flame tube music player (built on the sly because wifey afraid of explosions, I told her the pool is right there to put the thing out)
4. Beer fridge thrower (multiple people asked for this and I have a cool automated oven already that I can convert to a fridge plus a working fridge I am throwing out)
5. Various house projects, (Shelves garage, flower pentagon, retaining wall)

Most of these things are in various states of completion
There are others but nothing that comes to mind right now. Yet me know if there are others I should add.
