tried larger tube

Took an inner tube out of bike tire, from one of my mountain bike slicks. 26x1-3/8". My first impression? The size was perfect!

The nichrome wire wrapped about the plastic bottle core fit nicely inside the tube. It was protected from damage. No chance of electrical shorts. I was very happy.

Oh. Gave me another idea. I could run the power line on the outside...
