To make the midband for the control box, start with
a 1-1/4" PVC sink tube. You need the use the flared end,
that has a 1-1/4" inside diameter(which is 1-3/8" O.D.)
Since the flared section isn't long enough,
you have to "make it" long enough,
by stretching the inside a little.
Use a metal 1-1/4 O.D. sink tube inserted into the flared end.
Heat up the PVC with a heat gun, and slowly push the
metal pipe to stretch the plastic. You don't need
to go too much, just enough so you have 1-1/2" plus
a little extra to play with.
Measure and cut off 1-1/2" for the band.
Now you need a piece of .040" thick sheet styrene,
cut to1-5/16" wide by 4-3/8" long.
Using super glue, carefully glue the styrene
to the piece of PVC tube you made;
leaving 3/32" on either side. When you glue
down the styrene, do it small sections to
ensure you get it straight and smooth.
All that's needed is a little satin black paint,
and there's your midband.
