[R-390] Ten Turn mechinism question

[JAMES GREEN]

Good news! I must have been half asleep yesterday when I put the thing back together & counted the leaves. 

I took it apart today and counted again. There are 11 leaves on each ten turn shafts. Also,the reason the gear on the Mc shaft was not meshing properly is I had mashed the gear right down to the bottom and didn't realize I could adjust it up along the shaft later after I put the front plate back on.This kind of mistake is quite unusual for me. I must have been really out of it.
The RF deck is almost finished.I have all the cams aligned and the Veeder Root dial back on at 07 +000Mc.I have yet to align the rotary switch, clean and re-install al the tuning coils.Put the slug racks back in, replace a few caps and the RF deck is finished. This has been the most fun & rewarding part of the project.

 I saw one like this also and believe the unit only went to 30 mhz.  Never
saw anything in the manuals about it.  Maybe Chuck R can enlighten us.

I am putting my R-390A RF gears back together and have had no problem until
I put the front plate in place. The Mc side is kind of sloppy and the gear
on the Mc shaft will not stay engaged. I looked closely and counted the
leaves (or what ever you call them) in the ten turn mechanisms. I have 10
leaves on the Mc one and 11 leaves on the Kc one. Did I get them mixed up?
Am I missing one? I was pretty careful about not losing any parts. If I am
missing one it was gone before I started.
Any advice would be welcome.
Jim
