Little busy, today!!
The "frittered up" fairlead issue is somewhat resolved, for now! More on that later!!
Today the "old fart" here embarked upon HWSNBNs' challenge with regard to making
the forward dive planes retractable!! Oh what fun!! Hah!!
As the dive planes are "less-than-large", to say the least, the amounts of room in which
to drill, bush, pin and install retract linkage is, how you say, "minimal"!!??
But, "Grampa" here managed to come up with something that looks like it'll work.
After removing the factory "hinge pins", and cleaning out the center part of the planes where the control
linkage attaches, I did a little drilling. 1/32" diameter drill to allow 2 pins to be inserted which will
provide the hinge for "deployed-retracted" capability, as well as a place to attach operating links.
I attempted to bend some 1/32" wire to fabricate the operator links, but was unable to make the ends
small enough to fit into the opening. So, I "coined" the end of some 1/16" dimeter brass tubing, trimmed the ends, and drilled them out
for the 1/32" pins which will allow them to pivot mid-plane.
The hull end was drilled out to accept another 1/32" pin. It, in turn, will hold that little piece of 1/16" brass tubing upon which the planes will hinge
vertically!!
Here's the starboard plane assembled:
Both planes assembled:
I ordered some 3/32" O.D. tubing which will be cut to fit over the 1/16" hinge tube. It will be a "slip" fit, and will
also be cross-drilled, half way through, and a very short piece of 1/32" wire will be soldered to it for attachment
to the hull.
Internal operating "stuff" has yet to be thought out!! Why??? Cuz my brain hurts!! (lol) More to follow!
But for now, it's,
crazygary, out!
