Greetings! I've made some progress on my 4' tall tower lava lamp project. The base is done, glass vase obtained (nice thick walls), and coupling is done - very secure. I'm getting ready to mount the 200W spot light (on a dimmer - we will be going at this slowly) in the base and am looking for advice on space between the top of the bulb and the bottom of the glass floor. In my Magma 3' tower the space is less than 1/2", but that's a pro built lamp with the special low expansion glass, and mine is just normal blown glass. So, I was thinking an inch, or even two, to lessen the thermal gradients, but wonder if I'll end up struggling to get enough heat to warm up the whole column (5 gallons).
Advice and suggestions welcome!
Torpedo? Satellite? - they sound SUPER COOL! Please post photos when they're finished.
Larger, no. More of the same? Absolutely. I have two similar designs (a torpedo and a satellite) that I hope to make for the trifecta.
