One more note- Don't flame polish tanks if you want them to last for more than 10 years. The stresses that are created will eventually relieve, and cause micro cracks.

These raceways are still fine, but they have been dry for 10 years now (I'm thinking of putting them back in to service with LEDs). Some other tanks I made near this time have cracks from crazing.

Always buff the acrylic to get a good polish, and keep the heat down.
