Default Wow, Life Happens

Wow, life happens...

Dec. 7, 2017 I went to doctor's office for scheduled appointment after having
spent the weekend in much less than pleasant condition with swelling of my
abdomin. Within minutes my doctor's physician's assistant was wheeling me
into ER due to severe oxy deprivation (34%) to growing list of issues.

Allergies had contributed to what would be diagnosed a completely incorrect
pulmonary functionality, gall stones, and type II diabetes, to say nothing for
consequential effects...of a sedentary life style; any one of which doesn't run
flags up one's medical yard arm...but when they are concurrent, become life
threatening with a capital T!.

Fortunately for me, my doctor had already begun a gall bladder investigative
protocol which included an MRI on the Saturday preceding my going in to see
her on the 7th. Was said I was 4 hours from not flying any more models.

Three weeks later, I left ICU proceeding to transitional therapy to regain my
strength to a level I could begin outpatient therapy to regain strength to now
deal with stresses of ailment treatment and surgery for gallstones if found to
be the course of action. Thankfully and more fortunate than less, the stones
are too large to block entry and exit from the gallbladder...so no surgery.

Made move back to residence on January 23rd where I undergo physical and
pulmonary therapy between the expected poking, prodding, phlebotomy, and
obligatory doctor visits. Rather than interrupt my wonderful medical team, we
are not moving to Dallas but down sizing in Houston.

Sam's Kentucky construction is progressing well despite the ground hog. Our
shop's erected with electricity... The log cabin is under roof with electricity
installed Friday and Saturday before the latest snow/ice storm.

Resolved B-47 canopy issue courtesy of Bob Violett. Will post details with a
visual comparison to 1:1 documentation soon.

Default Return From The Light

Not to be over dramatic...but things are a whole lot better than they have been
in a long while :^)

Looking forward to our downsize move and getting back to the B-47 now that a
lot of the Kentucky build out is getting close to completion so Sam can get into
his new home. He and Judy have been on an extended excursion for too long!

Packing my plan sets yesterday showed a lot of what I needed to put in the
"past" as I have changed the direction of my hobby. With the new enterprise
focus on electric powered Giant Scale Modeling there are opportunities to
create competitive flying scale models weighing half or less than traditional
counterparts weigh.

Staying healthy is paramount to enjoying the hobby, whether you are in your
twenties or seventy and beyond.

Where are we now? Glad you asked...

Winging it...

Following installation of the CNC mill in the new shop we get back in the saddle
by cutting spar pockets in the foam wing blanks. I prefer milling them instead
of hot wire as the mill cuts a precision width and depth resulting in a superior
surface to adhere to. Note: That is a "D" spar leading edge in and outboard. It
parts at the inboard engine pylon.

I previously showed how Sam had designed linear servo driven screw jacks for
each control surface memicking the flaperon functionality of the 1:1, shown below.

Default Practical Replication

As for things still to be made (milled)...

While Dick has done a fabulous job "replicating" what he measured on the
remaining B-47's he visited, when it comes to utilizing the CAD drawing you
must "weigh" what is to be "gained" by including it all in a model. Purists will
scoff at thoughts of not replicating everything possible...it is the practicality
of cumulative AUW (all up weight).

If it were not for friends and associates...the B-47 project would never have
an opportunity to take wing. We return to physical progress by Thanksgiving
with Sam's move into what has turned into an epic build of Fort Collins (a
name I have given his log home...aka Fort on top of Mount Collins).

My recent visit to Fort Collins was a welcome respite. There's a lot to be said
for good friends, lower humidity, cool breezes, and the smells of a log cabin
construction deep in the hardwood forest of Kentucky!

Hi Ed, sorry to hear about your health problems; just returned to flying myself after a lot of down time with cancer i.e operations, chemo, radiation. Been some years since I've been on wattflyer, and was hoping to see this B47 in the air.....guess I'll keep tuned to see how she turns out.

Thanks for the welcome...back! Wow, your trek down the jetway to the
pilot's seat had a blessed arrival. We cross taxiways from time to time
on our way to taking wing. The one "flight controller" leads us along our
journey through life. God bless and fair skies with gentle tailwinds!

Friends within this hobby are a reminder we are never alone on our treks.

Default What's Next

I am close to printing all cockpit components, then creating aft end of the
two canopies. Canopy is Bob Violett's T-33 canopy extended rearward by
the addition of clear canopy parts aft of the rear canopy frame to permit
finished conversion to replicate a B-47 canopy, which turns out is 100%
scale because the 1:1 B-47 canopy was an altered T-33 canopy.



Next comes scale wheels assembled from William Brothers Model Product
off the shelf wheel components and 5.25" smooth contour tires. Off the shelf
but hardly standard...they are assembled inside out to provide the recess
required to replicate the 1:1 and accomodate Kavan electric brakes.



The brake surface is a drag brake created with fender washers inserted in
the recess cavity next to the down struts. Fender washers are drilled 120
degrees out and held in place with chaffered flathead machine screws. As
voltage is increased to electro-magnet, washer (brake surface) is drawn
more and more to the face of the magnet...slowing wheel rotation.



Outside of each bicycle main pair replicates 1:1 brake tension bar and vent
holes around wheel perimeter...from off the shelf Williams Brothers Model
Products wheel components.

Default Onward and Upward...

Down sizing has been time consuming, replacing items Paulette gave away... Honestly,
for the most part we are getting close to being back in the saddle with respect to moving
"things" where they are best suited Vs. where initially placed.

This permits me to get back to printing cockpit, and helmets for pilot, co-pilot, and navigator
/bombardier. Printing helmets and the navigator figure will result in almost a quarter pound
weight savings...the cast metal helmets were extremely heavy.




I need to add a visor and oxy mask w/hose and its perfect.
