[NJARC] plastic battery tubes

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.

 >> I have used the guard tubes they sell for T-12 lamps , I believe you 
can get them in Home Depot...  You can cut them down to size, and they 
are not expensive..

Working on a Zenith R-1000 with nine batteries that won't stay in the
