Making Wurlitzer Pouch Rings
By Bill Klinger
I wrote a quick g-code program for my CNC router and tried cutting
out some of the pouch rings from 1/8" thick Baltic Birch plywood.
The results are shown in the attached photos. They take a little
sanding to clean off the burrs.
A 60-inch square of Baltic Birch plywood costs around $14 and, if
the holding fixture was refined to hold the smaller pieces down better,
a sheet should yield between 800 and 900 pouch rings.
I asked an associate with a 90-watt laser if he could run a few
samples. He cuts all sorts of parts and pieces out of Baltic Birch
plywood and his laser can cut up to 3/8" thick material in one pass.
They would probably not need any sanding or cleanup other than a little
point at the starting and ending place on the outside of the ring.
