Instrumental Solution


The multiple layer instrument panel was really easy to create with a Sizzix 2D CNC.



Had to create an alignment jig to line up the instrument panel layers. Finally found a
PlastStruct 3/8" tube was perfect when placed through panel instrument openings.

While this sounds simple... ;^) drill a pair of holes with a precise center to center with a
hand drill... Rather than reducing a 2x4 to saw, or in this case drill dust...I'll go to my off
site shop and use a drill press.

Down sizing has taken a toll on the convenience of simply walking into another room. I
am very grateful the storage site manager permitted us to move from our original unit
to one within 50 feet of an electrical outlet... ;^) Space is complete with an overhead to
store fuselages, wood, kits, etc.

I erected a 2x4 perimeter frame then hung the overhead storage from it. I kept a 10x3
building board and about 90% of the power tools from my spacious two bay garage. It
gives me a greater appreciation of what I had...and have now!

For those not familiar with laminating layers to 'build up" an instrument panel...



1. Small hole layers (4) support individual LED illuminating each panel instrument.
2. Instrument panel layers with holes (2) for each flight instrument.
3. Instrument face layer printed on thin super bright white bond
............... (laminated with UV inhibiting clear adhesive tape)
4. instrument panel layers with holes (4) for each flight instrument.

Layered panel gives depth and when a resister is utilized the LED illumination is subtle.

Will post video of how panel layers are created later. Somehow camera batteries do not
retain their charge for more than 1 year... ;^)

Another B-47 Project?


Anyone taking a serious look at my cross section (former) drawing? Would really like
to see another B-47 built. There are and will be only three r/c B-47's flying next year...

Back In The Saddle




Sorry for not having posted anything more recently. Things have been a wee bit distracting. I will be finishing up the B-47 cockpit in the next week or so. I completely redesigned the cockpit providing as close a match to the 1:1 as possible given the process chosen. Pilot and co-pilot will be finished immediately afterward.

Shortly Sam and I will acquire a second CNC mill. One which will permit a full 15" Z axis from a single pre-laminated Hi-Load Styrofoam plank instead of limited to using two inch and three inch then laminating them post milling.

Aside from the 30% reduction of mill time, the thin edges of each thinner plank were in harms way until laminated...which in itself was subject to misalignment issues vs. a 50% top~down and bottom~up milling session, leaving feather-less edges.

More as it progresses...

Flite-Metal B-47 Progress


We're about to fill in the shop space after dropping the overhead and installing HVAC & Vacuum System.
Resurrecting the mill, vacuum form, work benches, storage, and building out tool spaces will take another
two monhs...given the weather keeps on being warmer than usual.



Friday, Sam finished painting the cabin's basement office. Internet goes in followed by desks,
computers, digitizer, and Epilog.

...

Has anyone following this thread begun a B-47 with the resources shared here and over at the main project site?

Hi,

We stayed over night in Tehachapi ,CA. on our way to CalFire in Sacramento to pick up OV-10D parts from
the OV-10 prototype (mule) 155395 . Crossed from Mojave on a quote unquote short cut...

Surprised with all the EDF focus you have never dabbled in some degree of CAD. I more or less backdoored
my way into it by reverse engineering work begun by others but never completed. My B-47s started with all
of the known drawings (artist renderings and measured engineered drawings from maintenance manuals).

Meaning the differentials between each...collecting all available cross sections then placed them onto one of
Chris Dave's (Brit aviation artist) most accurate line art drawings. From there I lofted the shapes between the
known cross sections. Before long I had created the "analog" drawing below.

Dick Reynolds (a non r/c modeler) in Va. was beginning work on another B-47. Over the course of two years
he and Sam (my partner in this) measured and photographed eight B-47 located across the country. I created
a project dims sheet indexing all known dims of the B-47E and WB-47. We could not audit the drawings and
cross sections derived without Sam and Dicks measurements. Dick created CAD drawings from cross sections.

That's all it took to be where we are today. After Sam's retirement home is completed everything get back

Way Back Machine...


The reason I dove into this project so obsessively is I had a personal experience with the B-47 way back...when I was in elementary school... I lived close to the school and walked to and from daily. (Yes in the snow and rain...;^) Normally I sat on my front porch upon return. This was back in the Duck & Cover period with its air raid sirens and crawl under the desk routine. My hometown industries manufactured strategic materials for nuclear weapons.

As I sat on my doorstep I was startled by a loud roar of "something" approaching from my right. The sound grew louder and louder... suddenly a B-47 approaching at not much higher than 500 ft burst into the center of my view. It immediately pulled vertical performing what for all general purposes was an Immelmann Turn (LABS Maneuver).

.................................................. .Clk-Here-2-C .................................................. .......... Clk-Here-2-C2

I had begun building rubber powered free flight models during this time. From this point to today I sought to perform the LABS with a model jet. Its obvious this could not occur until Recip/EDF/Turbine power became a reality. Not only a reality, but power enough to overcome gravity... So, here I am all these many years later...struck with a mission of my own.

Nothing difficult about what I have done. Its the same as any scratch built project. The only difference is most of my documentation was incinterated by the FBI at the Boeing, Douglas, and Lockheed facilities manufacturing the B-47 at the time the B-52 began manufacturing. The documentation I obtained was mostly from former employees who took T.O.'s home with them... This amounted to something close to 35 gig and explains why some of the best line art drawings were Russian.

All my original drawings were analog using Microsoft Image Composer and Adobe PhotoShop. All along I sought help from CAD hobbyists. For the most part, this did not work with respect to continuity until Dick Reynolds in Norfolk, Va approached me for a copy of my documentation.

Dick is a Newport News retiree who had extensive drafting and desired to learn 3D. Ah, finally a professional hobbyist...a whole different thing. .. ;^) I and my project partner acquired the software Dick used and we were off to the races...or in this case, the runway.
