The great bridge saga continues…

Today I received an update from my friend, Clark C., who is helping construct the two Rock River lattice truss bridges for the branch.

Clark is a true craftsman. And in the tradition of craftsmanship, he is testing the design approach to the bridges. Below are two images that show a “test bed” span. He is testing such things as lattice thicknesses, materials approach and heating the acrylic to help form it for alignment, etc. All this attention to detail is greatly appreciated and it will make for a spectacular presentation once completed.


Also: this last weekend I was at Trainfest in Milwaukee promoting the ProtoThrottle with Michael Petersen and Nathan Holmes. It was my first time at Trainfest and although it was rather grueling standing for almost eight hours both days, we all had a great time.

Nathan had graciously agreed to 3D print both bridge abutments and the one pier I needed. I plan to “skin” the three components with plaster and then distress, chip, and weather them to fit within the scene. Below is a rough setup showing the girder spans in approximate placement.

New addition for the track gang

It’s been a while since my last post and not much has been happening on the layout because of business commitments. But I did add a new tool to help me with the remaining track laying – four custom track weight/gauges.

Since I’ve been working with a machining company to produce faceplates and handles for our ProtoThrottle, I asked them if they would machine some steel to help me hand lay my track more efficiently. They agreed, so I sent them some simple drawings and, bingo, relatively heavy track gauges that will work perfectly for my code 70 rail.

These are going to be a welcome addition because they’ll hold the rail securely in place because of the steel’s weight. Plus, they will come in handy for other uses where I need extra weight to hold something in place.
