Moving to production of bracket parts, it has become obvious that there are times of day when the natural light in the "machine shop" is glare, not helpful illumination. Later in the day, sun through the big playroom window raises the afternoon/evening temperature to hot. And then there is the dog who demands attention. I'm becoming a night animal again.
The need to drill small holes identified the shortcomings of current drill chuck for the mill. A 0 - 1/4" drill chuck and arbor ordered.
The four needed single-headed semaphores have arrived. The remaining ten dual-headed semaphores are back ordered and may appear someday.
Made a simple jig to drill a small hole down the middle of 1/2" dowels to mount the semaphores. Need to raise the semaphores so arms will clear passing locos. Should paint them "concrete" gray.
Instructions with the Semaphores say to drill a 1/8" hole to mount a signal and use a spot of glue to hold it in place. I think a press-to-fit hole is a better idea. The tube at the bottom of the semaphores is 0.090" OD; a #43 drill bit is 0.089". If all else fails, I can always use glue later.
Note: Making 32 of anything is boring. Should be ready to use the new drill chuck when it arrives.
