Here’s my first update for 2008. The initial builder’s log can be found in the MLS archives
As seen in an earlier message (archive page 6), the wheel castings have a large sprue to remove.
Using my portable bench vice, I had good luck with using a jeweler’s saw and bench grinder to get rid of most of the sprue material.
I cleaned up all 18 wheel castings required by the Locomotive and trailing car before going on to the lathe for final machining.
As I posted earlier I decided to use a simplified process to do the machining, here’s the first step:
- I held the wheels by their tread in a 3-jaw chuck and cleaned up the backside surfaces of the wheel where the sprue used to be. The backside’s center hub was faced-off and trued-up to its diameter of .5165”.
