[NJARC] plastic battery tubes

[oldradio at comcast.net]

Hi Bill,

If after you split them, hit them with some heat (hairblower) and put a band around them, slightly smaller than a D battery.  After cooling take off the band and they will hold the batteries even better.

Congrats to all on this substitute.

I wonder if you take the entire 48" length and fill it with batteries, what the voltage would be?

73, John

Looked at the T12 guard tubes, but they were about 1/4 inch loo large 
(ID).  Went home disappointed, but then while explaining my plight to a 
friend, I had an epiphany.

After cutting the tube to the correct length, 6 1/2 inches, I cut the 
tube lengthwise, from end to end, and the tube contracted.  So I 
inserted 3 batteries, and the natural tension of the plastic closed 
around the batteries.  Applied some solvent type glue that seeped 
between the surfaces and that was it!

Trimmed the edges with a scissor, and it looks almost factory.  The 8 
foot tube was about $5, so at 6 1/2 inches per tube, I can make 14 
tubes.  A guy on ebay is selling the battery tubes for about $20.  So, 
if I charge only $10 each, that's $140!  A profit of $135!!

Don't attempt this, I have a patent pending.

can get them in Home Depot...  You can cut them down to size, and they 
are not expensive..
