Spacer Mod for Large & Centered Rasters

This modification is courtesy of Mike Sell. Thanks Mike!
I have tried setting up a Sony 12xx with a non-standard distance-to-screen
for the medium spacer (the only one I have). The raster ended up being a little
off the face of the blue & red. I could have made the raster smaller but it
still was not centered (neither good for CRT wear).
Here is the modification I used in place of the Sony spacers. This set up
allows you to keep the raster large and centered while aiming the B & R guns.
The first picture (above) shows the springs and rubber grommets on the CRT/lens
mounting screws. These can be found at any hardware store. The springs are
medium strength and 3/4" length. The rubber grommets are 1/4" thick, and are
necessary to allow the CRT & lens some movement on the inner mounting bolts.
