Tools, along with a set of magnifiers so I can see this better, I have to get 26 stars in place
P1180736
Each star will get cut out separately, and one at a time I’ll set them in the water and with a fine paint brush slide them into position

P1180452
Spoiler bay, and door with hinge pockets in place
P1180453
spoilers are made of 1/8 ply, and retained when down at corners with magnets and screws. I’ll need to do some finishing on these and allow for solartex thickness around opening
P1180454
I hope I can drive these open with the 6100 servos, and have them close by themselves. Rather not get into linkages which are a nuisance, and often cause servo hum or need wide tolerance holes or slots at the ends, this can get complicated.
P1180456
Hinge pocket from the underside
P1180460
Fuselage top cap retainers, the LE is held in place thru the shape of the wing LE, and at the rear I have added some ply slide type retainers/clips. Once the top cap gets slid back it is firmly held down at the rear, and of course the LE is held in with the round button that fits into the boom. Voila, I hope this is not to complicated, this scheme means no tools or screws which is a plus.

One strip at a time, either side. I spend about 20 minutes or so per strip planing and sanding to shape. Once it fits in snugly to the previous piece I add the glue, clamps and pins. Slowly but surely I’m making my way around. This is gonna clean up really nice and be a beauty when stained and finished.

After the third day of sheeting I am at this point.:):) Most of the time is waiting for glue to dry.

Wing struts, the BA will likely fly without them, but that wouldn’t be authentic. They are a nuisance so hopefully If the 4 screws get lost they can be easily replaced, of course if it was a display model I could just glue everything together

P1180284-001
I have gathered some bits for the struts, had to consult with Boeing as the Parts List continues to grow for this plane.. :) Collars 6-32 t-nuts and screws. As well some music wire and aluminum tubing.

It’s morning here, and it snowed overnight all schools are closed. I just shoveled a path to the shop and the Chicken Run.

We have had a couple snowfalls since Christmas however yesterday most of that snow was gone. Last nights snowfall appears to be around 10 inch.

Oh well :):)

P1160929-001

 

P1180165-001
The more I looked at the position of the tow hook near the wheel the more I realized it wouldn’t work, and lead to a mess:):) So, I’ve marked a point forward at the keel where a line at an angle of 30 Deg from the CG meets the keel. Better
P1180172-001
Some BA’s I’ve seen had no root fillets where the stab pieces meet the boom. That didn’t seem so clean, so I have fashioned fillets
P1180173-001
Fin fillet, rounded at 1″ diameter where it meets the boom. Later I’ll sand it down flush with the boom so the fin touches the boom at the center
P1180175-001

Yesterday there was very little snow left from the couple snowfalls we have had since Christmas. Looks to be app. 10 inches out there , oh well:):)

It’s been 10 days I see. Most of the work recently has been related to finishing the wings and how they join to the fuse. So, not a lot of opportunity for new pictures.

Snow storm imminent 4 -6 ” snow in the hills, Colchester and Cumberland Counties in Nova Scotia. Rain today, but temperature cooling thus snow tonight.

Last year we had plenty, mind you not till the end of January.

Febuary 2015, plenty of snow headed towards Truro over Nuttby Mtn.

Boom cut to required length, I’ll add a button later to close the opening.

Laminated 1/8 ply for support where wing supports later attach to fuselage

P1180016-001 P1180017-001

Trailing edge, with under cambered wing I thought it best to make the bottom flush with the ribs, as the top is easier to sand later where the TE is thicker then the ribs

Wing servo wiring and connectors pass thru the ply root ribs

P1180010-001 P1180011-001 P1180012-001

The 1/64 ply on the wings trailing edge where the ailerons were cut out requires a bit of trimming. Easily removed with a plane taking care not to hook the ribs as I pass by

P1180008-001

 


 

Nov 26

I cut some tip sheet from 1/32 ply

P1180005-001

In order to get some of the root work done on the wings, I am back at dealing with where the wing meets the fuselage. With Plug in Play wings, I need some structure to support the connector for the servo wiring as well as a fairing between the wing root and the fuselage. To complicate this all , I want a removable boom.

P1170991-001 P1170992-001 P1170993-001

 


 

Nov 22

Setting the leading edge ply from one of the ailerons. When the ailerons get cut out they develop a life of their own, so I made sure to add the diagonals before the surgery and then I have them held flat and straight while the glues sets

P1170983-001

Here both leading edges have been added, they will need a little cleaning up

P1170984-001

The wing where the aileron was removed, once this is cleaned up and flat I’ll add some 1/64 ply

P1170985-001

Since the leading edge d-box ply hasn’t been added to the wing yet, it is still rather flimsy, so I have staked it to the board flat and straight.

Then I glued the ply to the trailing edge opening

The tip ply was not part of the Partial Kit, so here are a couple of them cut from lite ply. They will later get glued into place then get sheeted with 1/32 ply

P1170955-001 P1170956-001 P1170959-001

The little aileron sub ribs at the tip, just seemed a little small for the rest of the wing. Here I fashioned a couple larger ones

Nov 16

The notches needed to be cleaned up on the ribs, and made a little deeper to accommodate the 1/4 x 1/4 spars and allow the 1/32 LE Ply to overlap.

Some choose to use 1/16″ sheeting, I’m not sure how well these ribs would work If you have to remove 1/16 ” from the top and bottom of the ribs, and then change the notch at the LE.

P1170928-001

The ribs for the tapered portion of the wing also need some clean up, and deepening

P1170930-001

I’ve decided to add some sheeting over the 1st two ribs at the root behind the main spar, so I have to remove material from the top of the 1st two ribs and add some notches for a drag spar.

 

P1170931-001

Nov 14

Notching the trailing edge of the inboard section of the wing, I had marked them previously with the lower spar material, and run both pieces between blocks to control the depth of the cut. Later I pass a file thru to clean out the slots and check for rib fit.

 

P1170912-001 P1170913-001 P1170914-001

Quite a kink in the LE where it transitions from W10 to W12, and it can be seen when the ribs are stacked

 

P1170915-001

I’ve changed that and modded both W11 ribs

P1170916-001 P1170917-001

Also a little concerning with the length of one of these ribs, as it really doesn’t fall in line. I’ll have a closer look at this when I get the TE for the aileron in place.

P1170918-001

W10 shown here 3rd rib in from the left also needs to be trimmed up a little

P1170919-001

There much better, now the LE will sit in nicely in all the ribs. Laser cut ribs.:):)

P1170920-001 P1170921-001

Trailing edge of the aileron, and last one third or so of the wing. It gets glued together in two places

P1170922-001

D-Box sheeting

P1170923-001

Most ribs out to the bay with the aileron servo, need an extra hole for servo wires

P1170925-001

It would have been nice If I could have notched the TE of the Ailerons, that looks like it won’t be the case though.

Maybe I will consider a Gusset where there are no diagonal braces

P1170927-001

 


 

Nov 13

Fuselage wing rod tube, square and perpendicular and all that jazz.

P1170883-001 P1170884-001 P1170885-001

And now onto the wings. a lot of layout work here before I can secure anything to the board.

I discovered as well the TE supplied for the ailerons is a little short compared to whats on the plans. It seems the last bay is a little wider at the tip. I’ll make the pitch between all ribs more or less the same. when I add the tip ply, I’ll extend that slightly to get back to the same wing length.

Also the chord is a little greater on the plan then what the ply root rib cap will cover. I will set the 1/4 x 1/4 spars as shown, and move the TE for the inboard section of each panel a little forward.

P1170904-001 P1170905-001 P1170906-001 P1170907-001 P1170908-001

I have marked the lower spar wood as well as the TE 1/4 x 1  for the rib locations on both panels. I can’t imagine one wing panel being different then the other:):)

P1170909-001

 


 

Nov 7

2nd set of root ribs for wing saddle. The plans don’t have a lot of information for wing to fuse connection.

I’m gonna make the wings plug and play with the supplied 5/16 wing rod. The boom will be removable, however the wing rod tube will be fixed to the saddle as well as the boom.

That means the saddle will be attached to the boom, and when removed the servo harness to each wing must also be removable and stays with the fuselage.

I reckon in most cases though the boom can be left on for travel to the flying field as the tail feathers are removable.

The root rib cannot be tight against the boom as I need room for the harness connector that goes to each flap and aileron servo.

The boom is held to the fuse with a couple 8-32 bolts and t-nuts.

My solder of choice for cable ends and terminations, a Silver alloy solder which requires a little more heat and special flux.

Lurking in the Weeds.

The tail group is together and fitted to the boom. I still need to add some brass tubing for the stab pivot pin. However it has come together rather nice.

I cut a new set of root ribs for the fuse, something tells me these will allow me to blend the wings to the fuse a lot nicer.

I will sand them and add the holes later

P1170824-001

I wasn’t happy with the light ply stab horn, so I put one together with a couple pieces 1/16″ ply and some CF in between

P1170833-001 P1170834-001

Some may run the stab rods straight thru the ply horn, however I’ve added a couple pieces 1/8″ brass tubing to increase the bearing area.:):)

Overkill perhaps

P1170835-001 P1170836-001

I have a nice stash of old dental bits and they come in handy when I work with the CF, in this case a slot in the tail of the boom to accept the stab horn

P1170837-001

Here the sub fin is in place

LE to TE Joiner, the plans show the trailing edge formed with 1/16 wire, so a little improvisation is needed:)

P1170805-001 P1170806-001

adding the trailing edge, as the stabs are built flat, I’d reckon the flat side is down when put onto the plane

P1170807-001 P1170808-001

Stab tubes and rods are added separately as they are not part of the kit, I am going to add some filler between the spar caps and the tubes add the root end

P1170809-001 P1170810-001 P1170811-001 P1170812-001


 

Oct 21

I put the 3 pieces of the trailing edge together for the stab, of course this was done twice, and they where both done on the same setup for accuracy. It appears best to notch them in 3 places to accommodate the 3 ribs

The 1/8 tubes are in a different spot then shown on the plans , however that should not present a problem. Maybe convention says one rod should be in the same plane as the spars and that’s why this was done

I’ll mark the lower spar strips later for locating the 3 ribs

Fin and subfin constructed of balsa and lite ply. Brass tubing and music wire not included in kit.

There’s also a Crackerjack bellcrank for the stab, that finally is hidden in the subfin, but being made of lite ply as best suited to use as a template, If you find it has the proper pitch between the Pivot points.

Wheel transoms further formed and drilled for axle. Not sure yet how to deal with the tow hook, I’d like to get it as near to the front edge of the wheel as possible, There’s a lot of lumber there though, and the style of tow hook I have needs to drop thru the base slot from above, :):)

added some glue, the plywood fuse extension is in place and the two rearmost formers are glued to the top fuse spar. I have a couple squares in place to get a correct setup.

Hawley Bowlus design
Based on the full size sailplane

The model will have a CF Boom

– 122″ or so wingspan

Bowlus Baby Albatross - 3-view

Mr Bowlus also created this travel trailer.

The Road Chief

bowl1

The original Bowlus Road Chief was produced in 1934. It was designed by Hawley Bowlus, a pilot, sailplane enthusiast, aircraft designer and builder of the “Spirit of St. Louis” – the airplane made famous by Charles Lindbergh’s first solo flight over the Atlantic in 1927. Being the brainchild of an aircraft designer, the Road Chief was, not surprisingly, based on aircraft principles with a streamlined aluminum body. Unfortunately, it wasn’t very successful. Only 80 Road Chiefs were built

Bowlus built several different series of streamlined travel trailers.

These were the Road Chief, the Papoose,  the Trail-Ur-Boat, the Motor Chief , and the De Luxe Road Chief.

Bowlus’ Baby Albatross sailplane, which was one of the first kit-built gliders offered to the soaring public. Approximately 100 kits were produced in San Fernando from 1936 to 1941. This pod & boom glider is often called “cute.”

P1170068-002

 

The plan shows music wire for all the trailing edges of moveable surfaces.

Aileron , rudder, elevator.

However supplied with the kit are balsa cut trailing edges which get glued together.

Some ribs however are slotted for music wire, and not cut to suit the balsa supplied Trailing Edges..

So, I have some options here, I reckon I’ll go with the supplied balsa, and modify the ribs to suit.

Horizontal stab

Observations

The holes for the 1/8″ O.D. brass tubes in the root rib and 2nd rib are not in the same location as shown on the plans..

I don’t know what that means yet, they may have been moved to not interfere with the vertical tubes used to secure the vertical fin.

Also the Lite Ply horn supplied for the stab does not have holes corresponding to those on the stab root rib.

LE tip on both stabs, as well as the fin is open to artistic decision, there is no parts included, I reckon a piece of sculpted 1/4 balsa will work.

 

TIP

Review these plans and review them often, compare what is supplied to what is shown and mark everything.

Don’t glue anything together until your sure how that part will impact the rest of the plane.

I’m going to enjoy this:):)

A view of a full Scale Baby from the 1930’s. Of note is the opening behind the windscreen, it is cut lower and a little rounder then what Col. Thacker shows on his plans

N18998

Notice the horizontal line on the plane view below, really not very creative.

I really like the curved cockpit opening sides.

20150328_074954-001

It appears the 2nd former from the right in picture below is missing a couple notches for stringers.( See pencil)

I haven’t been able to find any pictures anywhere of a Fuselage Build of this kit.

P1170091-001

Missing from the kit was the nose block which is shown below as being included in the kit. I will fashion a new nose out of some locally sourced wood

Also, included was a Model Builder article from Sept 1975. The complete write up is not there as any text from page 83 on is missing

Need wood, and need a parts list

Here’s a start for the wings.

P1170482

It appears the the spars are about 60 inches, however the trailing edges for the ailerons are a little shorter then what’s on the plans, So I will modify to suit.

P1170480 P1170481


July 25

Spars, 1/4 x 1/4 spruce 60 inch or so long, difficult to get and expensive to ship. Some like to join shorter lengths, however that’s not what I like.

I cut out 4 spars as well as the leading edge, which is shown as 1/4 x 1/4, but I like to place the d box sheeting over the leading edge, so I cut them to a size closer to 3/16 x 3/16

 

P1170483 P1170485

A couple ribs set between the spars

P1170487

P1170488

 

 

 

 

 

 

Horizontal stab spars and leading edge.

1/16 x 3/16 spruce for the spars and 1/16 x 1/4 for the leading edge.

 

P1170489

 

There’s something funny about these ribs for the horizontal stab. The leading edge is shown as straight on the plans and most certainly there’s a problem here. or maybe S1 needs to be flipped the other way  ???

Also the 4 holes for the 1/8 brass tubing are also cut incorrect

 

It’s really nice to have a bunch of “laser cut” pieces but when they are inaccurate, the average modeler will get frustrated, as you’ll soon find yourself scratching new pieces, or worse yet wondering what to do and seeing your dreams on a shelf in your shop

No worries though, I’ll get this correct and all will be well:):)

 

P1170490 P1170491


July 26

Fuselage assembly, this will likely be dry fitted together many times before the glue gets added. The formers are part of the kit, however all forward /aft stringers need to be added and cut to fit.

Add to that provisions need to be made to secure the

wheel

wing struts

R and E servos

main boom

tow hook

removable Cockpit cowling to get at ballast , battery, receiver and servos

and then the entire carcass needs to be sheeted.

Reminds me of a 32″ river boat I built years ago , which I sheeted with pine strips.

hhhhh

P1170506

 

Former F5 or C on the plans, is too tall and does not conform to the drawing. I simply cut off both of the legs to suite.

Also all the top formers do not have a high enough notch to suite the 3/16 x 1/4 lower edge spar to give a removable hatch some rigidity.

P1170507hhhh

 

P1170508

 

 

hhhhhhhhhhhh

Looking sharp.

There’s absolutely no information or pieces to tie the two wing halves in where they meet the fuse at the boom.

Standby for some wild and crazy ideas  :)                :)
