Thank you, a very good post. The only difference I can find between the two attachments was the addition of the following to the BUG ADJUSTMENT Section - included in the first attachment:
"The trunnion screws (they hold the lever and allow it to
swing) should NOT be lubricated.
Lubrication of such a small bearing causes more problems than help.
It attracts dirt, dander and dust, and on
some keys that have been "oiled" the lubricant had gotten between the
main lever and the dash lever.
residue causes the levers to stick when the dash lever is used.
This problem is much more common than most
Clean off the
lubrication with ammonia then water and let dry for a few hours before
reassembling. Moisture will weld your screws to the frame when the water turns
iron to rust!
Also take a strand of stranded wire or a pin and clean out
the trunnion screw cavity. I use a cheap
ultrasonic cleaner with ammonia or Formula 409 to degrease and clean. I usually follow up with another 5 minutes of
water and Dawn dish detergent then five more minutes with just water. Dry for a few hours and reassemble.
When tightening the trunnion screws, they should be adjusted
with the key set wide so you can feel the drag.
If the lever drags no matter what, it is rough and should be smoothed
with 600 then 800 then 3000 grit wet/dry sandpaper (or other) and tried
again. The correct adjustment is the
best of "minimum up and down play with minimum drag" - when adjusted
correctly, the lever will move slightly up and down as if it is tightened too
much it will bind."

You will find two files in this group's file section - see the link at the bottom of this message - the two files are somewhat similar I am afraid, but I put both up, you decide which one is best:-) Secrets of Bug Success is longer, but I think it also is about sending and how to send and bad dots caused by instability of the vibrator, &c.
I also attach the files - see if they go with the message.
À bientôt & 73, mon ami,
