[R-390] Crystal osc. dial drum transplant

[K2CBY@aol.com]

Swapping dial drums on the crystal oscillator shaft isn't an impossible task; it's just a little awkward. You have to detach the gear, remove the oscillator subchassis, undo the snap ring at the forward end of the shaft where it rests on the front side of the bronze bushing. Then push the shaft out the back. The dial drum then falls off the shaft.

If all else fails, you can restore the markings with a paper dial. I made one using Microsoft Word (which took a lot longer than removing the dial drum) that produces an exact replica of (white on black) type style, size & spacing. Contact me off list. I can send it (with directions) as an e-mail attachment or can mail you one or more paper copies.

Whatever you do, take care: The drum is indexed to the shaft. If you destroy the old decal, be sure you mark the "1" point on the drum and make a note of the direction the numbers go.
