Replacing "Perflex" Pouches in Universal Players
By Pete Knobloch
Bill is asking about others that have replaced these small pouches.
I have done many of these with few problems overall. I would have
thought that zephyr skin would be very hard to get a dish on the
leather due to the small size of the plastic ring and the stiffness
of the leather.
I use thin pouch leather with the smooth side pointing down on the
ring. This way I can seal the leather from the bottom side after
the glue dries and its trimmed.
When gluing to the rings you must not let any of the glue flow
toward the inside of the plastic ring. This greatly reduces how far
the pouch will move when operating.
I use a "Acrylic Polymer Emulsion" product called Golden Mediums
(GAC 100) for the glue. It can be found at many fine art stores.
Apply a small bead on the plastic ring then press it onto waxed paper
which removes most of the glue from the ring. Immediately press the
ring into your pouch leather skin and let dry. You then trim the
excess leather using scissors. I usually can get 40 rings glued
before I start trimming.
To get the dish I use some 1/8" felt punching glued to a small wood
board. I trimmed these down a bit and added some thin red felt on top
to help form the dish. Lay the pouch leather skin over the punching
then take a 1/2" diameter by 3/8" long piece of cooper tubing and drop
it down onto the leather, making sure the felt punching under the
leather is centered inside the copper ring.
Then I take the white pouch ring with glue (using the above process)
in one hand and lower it down around the outside of the copper tubing,
then press the copper ring down with a finger of the other hand then
center and lower the white ring with glue down on the leather. I then
go on to gluing the next ring close to the last one glued. Leave
enough room for cutting them apart later when dry.
Since the original pouches were 100% air tight, it is important to seal
them since leather is very porous, even when they say it was pre-sealed.
