[Boatanchors] Has anyone ever cut the glass top off a miniaturetube to re-use the base?

Thanks, Doug.  I have found the pins (both tin and gold plated from
Keystone) at Mouser.  In lots of 100, tin are about 11 cents each - not
bad. Gold about 2 to 3x (I didn't capture price).  Not sure about length -
need to check that.

At this point, most acceptable option (i.e. inexpensive with reasonable
quality) seems to be short pieces of 18 AWG copper wire inserted in 7 pin
sockets.  The Keystone pins are a nice option - again inserted backwards
into 7 pin socket and soldered (again I need to check length).

Your idea of drilling holes et al in pill bottle, pc bd, whatever - problem
with precision although with a bit of work one could come up with a drill
template. Also still leaves idea of having little custom pc board done -
still got to look at that (maybe $2 for pc board plus $1 for pins - not
bad).

So still more to go.  Great batch of ideas from everyone.
