DCC Impulses Column - 7
Now to hold the styrene strips to the side of the speaker while
I glue them. I use magnets, angle brackets, machinists ells,
etc. to hold the parts in place while I apply MEK to cement the
white strips to the speaker. If I want to protect the metal sur-
faces, I use a bit of wax paper.
For what it’s worth, I bought a large scrapbooking magnetic
cutting mat to use for larger projects.
When the cement is dry, the speaker can be slipped into the
shell and held in with caulk.

Roll your own connectors
It is frequently hard to find connectors that will fit in our mod-
els and have the exact number of pins for your installation.
Here’s how I handle it:
I build my own connectors. Not from scratch, but I start with
50-pin headers and cut them down to the size that I need. I put
polarizing pins into them by cutting them off the male side and
embedding them in the female side.These headers will handle
1-amp decoders and the appropriate wire.
When I owned Litchfield Station, I found a source for 50-pin
connectors that match the NMRA Nem-651 standard for
the small connectors
