Having used Scott Seickel's gear train tutorial, it is a 10 on my scale. The
first page: item #5, suggest a SUPER important item which is a large flat
hard surface and a clean floor. The next on my list is a logical method of
disassemble and getting the beast back together, in one working radio. The
parts n' piece have to go somewhere, which makes some grown men cry.
A couple work life times ago a technique was shown to the students while
attending a place of "School House Bugs". For some of us it came natural,
did it all of our working lives. The light bulb lit for the rest while
chasing bugs. It is all about where to place the parts n' pieces. Unless one
is real good; don't dump all the parts in a brown paper bag, shake real
good, invert the bag letting everything roll about the floor. At said
"School House Bugs" muffin pans were suggested as a place for the parts n'
pieces. The little lady of the house might not be happy using her cooking
ware in that fashion. But go ahead if you dare.
The work bench must be clear of clutter. Find a new home for the junk while
playing with the gear train. Clean/clear the surrounding floor. The little
steel ball in the Geneva Drive is going to fall, bounce, and find the crack
in the floor.
With that said, I've placed the RF deck/gear train on the right hand side of
the bench (work area). The left side is clean and bare of parts, tools, etc.
Follow along with Mr. Seickel's pictorial. Remove the first part, clamp,
gear, etc. Now place that item to the far top left of the bench. Along with
that piece, also place any clamp/fastener with said first item. Moving on to
the next item, place it below the first item. When getting to the bottom
edge of the bench, move over to the right and do it all over again. Repeat
until all the gears, clamps, geneva drive, etc. are laid out in some logical
order.
At this point go ahead and clean, deburr, lube to your heart's content with
the last item placed in logical order. Put said item back onto the RF deck.
In reverse order, get it back together all nice, clean, & smooth. The first
time I had one of these mechanical marvels spread on the bench, it took 12
hours start to finish. Finished, done, ain't gonna do it again. It is clean,
smooth, and last a long time. Next owner can sweat about cleaning it again.
