DCC Impulses Column - 4
Cut more pieces as needed now that you have the dimension
set by the fence.
What if you don’t have a factory-finished side to use? Put one
edge of the styrene against a flat surface (like the bed of the
paper cutter or the cutting mat on the Chopper II) and look
at the interface [2] between the two. If they are in intimate
contact all the length, that’s as good as a factory edge for our
needs. If not, trim a bit with the paper cutter to establish a
good edge.
Quick installation of some speakers

that can be used to quickly mount some

Slide the strip out until the freshly cut side is lined up with the
1 1/2 inch mark and make a second cut. I now have a piece
with three square sides that is as long as the blade in the
Chopper II and a bit wider than my final dimension.
Use the inside measurement side of the calipers to get the
width of the shell and lock them to it.
Use the extension rod portion of the calipers to adjust the
spacing between the blade (be careful, it is designed to cut-
very sharp) and the fence.
Cut the fourth side of the styrene strip by placing the factory
side against the fence you just positioned. This strip is now
square and should slip into the loco shell easily.

int the shell. Look below the speaker on both sides. There’s a
shim on the left.
