Jackrail supports

The jackrail keeps the jacks from flying out of the instrument when it's played. Two supports glued to the case walls above the register gap hold it at the correct position.

Now that the jacks are done, I've checked to see how high they rise when the keys are fully depressed. I will set the jackrail position based on this measurement.

Here's one of the two jackrail supports:


Both supports are made from Alaska yellow cedar about 11 mm thick. A 1/4" groove in each will receive the ends of the jackrail. I plan to cut off the non-scrolled end at a 45 degree angle, which will look nicer.
