Ball Clock II ~ Hour Ball Selector-4

by Jon Long Sr on October 18, 2016

img_4731After some testing it became apparent that an Index Plate was necessary to hold the selector arm in place once it has been extended.

It was important that the Index Plate was in line with the position of the balls in the upper & lower track.  This is so the vertical piece on the selector will pass into the appropriate slot on the Index Plate.

Tabs were soldered drilled and tapped (2-56) onto the lower track to provide mounting for the Index Plate.

img_4734I didn’t want to solder the Index Plate directly to the lower track incase I needed to change something on it.

If there is one thing I have learned during this project it is that you have to keep your options open.  It’s kind of like life, never box yourself in.

The index was necessary to establish the location of the lower gate to release the balls into the hour striker section.

Once mounted and tested, the assembly was reinstalled into the clock to check for clearances.

Things are getting tighter in that area and it is important to stay on top of it.img_4754
