Okay, so I could buy a resin powerpack frame from a club
member or even a completed unit, but where's the fun in that? :-) I have a
bunch of scrap acrylic and boxes full of old electronic components, so let's
do it! I laminated three pieces of acrylic together with Weld-On #4 and cut
it to size as indicated by Dave Painter's plans. I used a scroll saw to cut
out the initial interior shape, then took it to my drill press. I used
various Dremel cutting bits along with a cross slide vise to simulate a
milling machine.

The cross slide vise made it possible to do things like
cutting the shallow slots on the edge connector. I used a ball cutter to cut
the rounded slots along the inner surface of the sides, then used a tiny 1/32"
ball cutter to cut the holes on the edge connector for the contacts. Along
with Dave's plans, I relied heavily on photos of the original Librascope
card from Mike Davis, and the duplicate powerpack from
Bill Kendzierski.

I sacrificed some accuracy on the paint colors to go with
what I could find, locally. I cut pieces off a 1/32" x 3/32" brass strip and
inserted them into the connector end, to simulate the contacts.
