Finally, A Throwbar

As I may have previously mentioned, actually hooking up turnout points is one of the mental hurdles in my path to layoutdom (layoutness?). Today’s project was getting started on hooking up the points for high track with a throwbar. The method of pinning the two together was the challenge. Learning took place.

I had a plan that involved using very small hex bolts 1/8″ 00-90 that did not survive contact with reality. The clearance hole for the bolts is a drill number in the 60’s that turned out to be too big a hole to reliably drill in the tabs of the American Switch & Signal (now sold by Right O’Way) points. I managed one and then the next tore out. Break time!

For the second attempt, I went with an idea I vaguely recall from somewhere, cut down straight pins. The standard steel sewing pins almost fit through holes as-is so they work much better. They are easy to make which is fortunate since they also fly very far if your grip with the tweezers slips.

After assorted bits of filing, drilling and fiddling, the test fit was completed. I expect the installation of the rest of the throwbars to go much smoother.
