I just wanted to let people know what I finally did with regard to a
roller drum. I went into my attic where, low and behold, I found an
assortment of antique and very eBay-able turntables for those old
fashion records that many of you youngsters have never seen. I
actually have three of them that go back to my childhood up there. I
picked the Panasonic turn table with the built in 8 track player and
using a drill and some screws fashioned the spinning part to hold two
16 flask holders. Setting at an angle it spins them quite well at 45
rpms. I can load this contraption with about 10 flasks before it
starts to sound like it is working too hard and needs to be switched
to 78 rmps. Good enough to experiment with.

The hardest part was disabling the auto changer and automatic needle
arm. I had to go into the box and remove a gear in order to prevent
all chance that it would decide to "change records" when I turned my
back.

I have attached a lamp for illumination, and when I want to get really
silly I have some old speakers in the attic too, as well as a box of
8-track tapes. (If they still play I will be amazed. There must be
some organism that eats magnetic tape)

I probably could have sold the turn-table/8 track tape combo box on
eBay and bought a new roller drum. :-)

Anyway, thanks for the input...
