[R-390] PTO VFO End Point Adjustment tool

[Larry H]

Some time ago I started working on an R-390A Cosmos PTO that needed end point adjustment.  After reading the immense amount of doc graciously posted about PTOs, I decided to make the adjustment tool suggested by someone (whose name I can not locate).  I thank you!  They suggested making it about 3.5" long, so it could be inserted into the adjustment hole while the VFO and the front panel were still installed.  This made the EP adjustment very easy.  Thank you!  
Here's what I ended up with.

As you can see, its 3 13/16" long.  That's as long as I could make it and still sneak it into place to make the adjustment.  The shaft is aluminum so as to not distort the tuning.  There is tape and tubing on the adjustment end.  It did not start out that way, but I found that the tool usually found its way between the EP adjustment shaft and the access hole.  That is not good as the adjustment coil could be damaged.  So I added the tape and tubing to keep it centered in the access hole.  Now the adjustment is so easy.  I've used it on 3 different PTOs: Collins, Cosmos, and Progressitron, and it was easy to use.
I am very glad I made the tool, as getting the Cocmos EP correct was a long drawn out painful experience.
