Tool and Material List

Here is my tool and material list for that coupler installation:

Drill & #51 drill bit
Pin Vise & 2-56 tap
2-2-56 screws
KD HO coupler height gauge
A section of HO gauge track for testing height of coupler

The drill bit and tap are expected by the 28 so I don't expect to have that flat car done before the end of month. I have fallen a bit behind in the completion of my hobby projects. Here's hoping I can make a couple of these posts next month.
