Title: Sopwith 1-1/2 Strutter from Midkiff Plans for FAC WWI Combat
Post by: MKelly on March 11, 2019, 11:26:17 PM
I'm tired of watching FAC WWI Combat mass launches - it's time to join in!  I've had my eye on IronMike's Sopwith 1-1/2 Strutter for a while, so that's what I'm going to build.  At 29", Mike's plan is a bit larger than I like to box up and haul around, so I've reduced the plan to 25", which works out to just about 1/16th scale.  Still a big model for me, but I've been pleased with how the T-28, Wicko and Wedell-Williams are flying and this will be about the same size as those models.

I hope to make this one up as one of the aircraft that flew off HMS Furious late in WWI, which would allow me to fly it off the deck in the carrier events at WESTFAC this October.  I've found some photos and some fascinating reading regarding the early carrier activities at https://www.kingstonaviation.org/sopwith-day-by-day/1918.html (https://www.kingstonaviation.org/sopwith-day-by-day/1918.html).  This is a really great site for researching Sopwith aircraft - but beware, once you start looking time will get away from you...

Plans are copied, templates for parts and lamination are printed, and it's time to start cutting wood.

As always, comments, suggestions and occasional ridicule are welcome.

Mike

Gosh you don't pause for breath do you?  Why are you on?

I built Charlie Newmans with a KP1 as power unit - quite sedate actually.  So look forward to this.

Thanks David - can't stop for breath, too many thing I want to build...

Off and running - laminated the fin outline and the first set of wingtips and started cutting blanks for the cowl.  I haven't had much luck previously with the circle cutter.  This time I hit the center point with a bit of thin CA - this kept the pin from wallowing around in the hole and the discs came out pretty clean.

Somehow lost the pic from the last post.  Building time has been sparse this week as we've finally had some flying weather.  Did manage to get the fin and wingtip laminations done and the fin assembled.  It's a start...

To me, the stab plan looked a bit different from photos of the Strutter.  I found some prints of the stab on the Imperial War Museum site, scaled them to match the plan, then used that as the template for the laminating form.  All the interior structure lines up nicely with the blueprint, it was just the tip shapes that were different.  Laminated the outline with three strips of 1/32x3/32 and all is good.

While that dries hard I've framed up the fuselage sides.

Nice Mike - I noted your additional launching crossbrace!  I'd do that.

Thanks Mike - I figured the extra cross member was good insurance against my nervous hand crushing the fuselage during a mass launch...

Marcelo, I use both a magnet board and a pin board for building. I like the magnet board for fuselages, use either one for wings, and prefer the pins for delicate work like tail surfaces.

Fuselage framework is assembled and off the board, now starting on adding the formers.  Stab is assembled and I added the control horn mount to the fin.  Weights look good so far - 3g for the fuselage frame, .37g for the fin and 1.9g for the unsanded stab.  I also cut out a plethora of ribs in three thicknesses.

I the background of the last picture is the latest delivery from ebay - a Comet XP-38 (37.5" span) and a Megow Caudron racer (20" span).  Rich Adams, that Caudron has eyes on your Folkerts...

If you scroll about 1/3 down this page:

you will find decals for Sopwith fin logos in FF sizes. I've got a few spares if interested.

Nothing will catch my Folkerts bwahahahaha! Nice pick for a WWI subject and beautiful start. Pay close attention to tail weight and incidences. My Pup wanted too much downthrust until I added TE up incidence same as my DR1. One of your slick adjust-a-glide mechanisms would be a huge benefit.

Post by: MKelly on April 01, 2019, 11:56:18 PM
Thanks Wally and Rich!  Bill, appreciate the lead on the Sopwith decals - the big Strutter on that page was quite a masterpiece.  At this point I'm not sure I'll need the Sopwith markings on the tail.  All of the pictures I've found of the Strutters on the Furious have very little in the way of markings, just an aircraft number on the fin and sometimes codes on the aft fuselage.  Some of the references I've read indicate that many of the late-war naval Strutters were re-manufactured from war-weary bombers, perhaps that's why they don't carry the Sopwith markings on the fin.

As far as progress on the model, I put the cabane mount tubes in, added the rear stringers, then got the top sheeting on the fuselage.  While the fuselage was jigged up for the sheeting I set the tail group on it for a little motivational observation.  I'll cut the forward cockpit out once the rest of the bodywork is in place and I've done some sanding.

A question for the forum - were the skylights in the top wing on the Strutter some sort of clear sheeting or just clear-doped fabric?  I haven't found a crisp picture that shows this detail.

Mike

Post by: Indoorflyer on April 02, 2019, 01:07:30 AM
I've wondered about that too; not all Strutters were so equipped.  The Profile Publication mentions "transparent" which implies a plastic type material.  Any fabric would be translucent at best, I would think.  Which specific (single seat?) Strutter are you building?  The progress thus far looks superb!

Post by: billdennis747 on April 02, 2019, 02:02:35 AM
Hello Mike
The upper wing panels on some Strutters were transparent Cellon.
Only the very early Strutters seem to have carried the fin logo, along with unpainted cowlings. They provide some relief from all the PC10
This is the Strutter from the Avetek kit
I have the Windsock Datafile on the two-seater which I shall not need again, if it might be useful

That is one very nice looking Strutter Bill - hope mine comes out comparable.  Thanks for the clarification on the skylights.  I'm interested in the datafile - send me a PM and we'll work out payment etc.

Had a bit of a setback yesterday, discovered that I'd distorted the front of the fuselage while gluing on the sheeting.  I cut loose the front left corner, trued up the framework and installed some extra gussets to get things back to square.  This morning I'll clean up the sheeting and glue it back down.

Easing back into the build after a week off for the contest at Gainesville and subsequent repairs/alterations to the fleet.  Today I sanded the stab to shape and spent some quality time comparing the Windsock Datafile (thanks Bill!) to the Profile publication and the photos in the Jack McCleery book.  Still trying to decide whether to build the skid undercarriage, wheeled undercarriage, or a setup that would allow me to switch between the two.

Post by: MKelly on April 15, 2019, 11:44:37 AM
Thanks John. 

Got the cowl side sheeting on yesterday.  While that dried I sanded and notched that huge stack of ribs.  Given how thin the airfoil is I've decided to use 1/16" square spars rather than the 1/16x1/8" shown on the full-size plan.  I'll put shear webs in the main spar inboard of the interplane struts.

Once the cowl sheeting was dry I glued in the "cheese cutter" stringers on the sides of the fuselage.  I made the bottom ones out of basswood to (hopefully) preclude handling damage while working with the noseblock during flying sessions.

The stringers ending in that upright strikes me as a very neat way of blending the fuselage contours. Simple and elegant.

Post by: flyfac on April 15, 2019, 09:02:00 PM
Lovely joinery, Mike.

I too like to stack sand ribs like that.  If I'm careful (OCD?) enough, I'll even order the stack so the ribs that wind up bearing the interplane struts are heavier/stringier than the non-load bearing ribs. 

One trick to share:  Instead of pinning the rib stack, I now give each rib a swipe with a UHU glue stick.  After about ten minutes, the glue is set enough that it's easy to sand and notch all the ribs as a block.  To separate them, spray with block with isopropyl alcohol.  The glue will soften enough to separate your now perfectly identical ribs.

Best of all, no more pin-poked fingers.

Best,

Scot Dobberfuhl

Post by: MKelly on April 16, 2019, 10:43:04 PM
Thanks guys - I'm enjoying the woodwork.

John, Mike laid out the side stringers pretty much just like the real aircraft did, and it does do a nice job of transitioning from the round cowl to the slab sides aft of the forward cockpit.  The real one had some near-vertical braces (formers?) between the stringers that show through the fabric in most pictures - I'm debating whether to try to emulate them.

Scot, I've been using the glue-stick trick when sanding formers and pairs of ribs - not sure why I didn't think of it for the rib stack here.  It works well - I usually just put a dot of glue stick top and bottom (or fore and aft), then use a knife to pop the pieces apart after sanding.

Not much photo-worthy accomplished today - notched the LE and TE stock for the ribs and sliced off some semi-stout 1/16" square stringers for the spars.  I'm going with the same size LE and TE stock Mike spec'd for the larger scale, so there's a bit of meat available in both pieces to notch for the ribs.

Mike

Enjoyed getting back to the Strutter after a nice weekend of flying and family time.  After notching the LE and TE for the ribs and slicing off some spar stock I pinned things down and framed up the top wing.  Once this dries overnight I'll put in the shear webs, top spar and TE center framing.

Your LE and TE notching jig looks neat Mike. Did you have a depth stop on the saw - assuming it was a razor saw that you used. I have used the old hacksaw blade idea for notching ribs and it would have worked well in your jig as well. One blade is 1/32 - 2 for 1/16 etc. The trick in using them is to pull the blades against the teeth gently and not to use them in the correct saw direction.

Filing all these good ideas away in the brain box :)

John


Title: Re: Sopwith 1-1/2 Strutter from Midkiff Plans for FAC WWI Combat
Post by: MKelly on April 24, 2019, 02:55:40 PM
John, I used a homemade notching tool to make the slots - just a piece of 1/32" ply with sandpaper on one edge and a balsa depth stop on one side.  You can see it next to the LE/TE stack in the first pic on post #26.  Using a saw blade as you suggest might make for a quicker cut - the notcher takes a bit of back and forth to get down to the desired depth.

Top wing is assembled.  I ran the strut braces from the rear spar all the way forward and added some small gussets between the spar and ribs at the brace locations, probably overkill but it makes me feel better.  I put 1/32" shear webs in the inner two bays on the main spar.  I also boxed the inner bay at the aft spar to provide a support for the skylight glazing, and added a 1/32" shear web to the next bay to keep things strong between the cabane struts.  Given the "W" cabane structure this is probably all unnecessary, and I'll only have myself to thank when the model comes out heavy...

I'll cut the wing panels apart at the center ribs and sand in the dihedral bevel after the LE and TE have been shaped and the wing sanded.  The center ribs are firm 3/32" sheet, so there should be plenty of meat there for the bevel.

Cheers,

Mike

Bottom wing is assembled.  Top spar isn't glued in the center section, I'll do that after sanding the wings and setting the dihedral.  I boxed in the area under the interplane strut mounts and glued some blocks on top the box to hold the struts and rigging.  Blocks will be sanded flush with the wing upper surface.  The box will let me open the covering on the underside of the wing for rigging or repairs if necessary.

Top wing has been rough sanded - still need to finish shaping the leading edge.  Top wing is right at 6 grams at present.

Clean/precise woodworking in there.
Was surprised that the trailing edges are 'uncut'  so far.   
Shaping Ledges is tricky enough..I would end up ruining the ribs trying to shape those Trailing edges. 
Please photo your technique if you could ?  so I can learn 'how to'
 thanks


Title: Re: Sopwith 1-1/2 Strutter from Midkiff Plans for FAC WWI Combat
Post by: MKelly on May 01, 2019, 05:26:05 PM
Thanks Fred.  To shape the wing I roughly hand-carve the LE and TE to about the right bevel, then use a sanding bar (which is just a 1/4" thick scrap of wood about 1-1/2" wide by 8" long with 220 grit glued to one side and 400 grit glued to the other) to bring it down flush with the ribs.  As you can see in the picture I put the wing at the edge of the workbench, hold it down by both the edge and the spar with my left hand and sand along the edge with my right keeping the bar at a diagonal along the edge.  When the bar touches ribs you'll get a distinct scraping sound which tells you to stop, check if you've sanded the edge flush with the ribs, and if not to adjust your sanding angle so you don't flat-spot the ribs.  Once you've done it once or twice it becomes a pretty straightforward process.  You can also put masking tape over the ribs to protect them - this time I got lazy and didn't use the tape.

I think I got this technique from ModelAce out of his Ki-61 or P-51 build threads - it works well for me.

Top and bottom wing are sanded up and pretty much ready to cut the strut notches and set the dihedral.

Mike

Post by: OZPAF on May 01, 2019, 06:00:09 PM
I have used the same technique and it works well - especially with masking tape on the ribs. I like this general approach of building the wing in a single unit and then separating for the dihedral. I think it is a much better approach.
That's quick progress Mike.

Well I figgered that I would piggy back on Mike K's great build on the 1/2 strutter.
Dragging out an old Camel 3 view Ive studied since I've lived up north, I whipped up
some laser cuts. Coincidentally this 3 view is from the same 70's article that was the
genesis for his 1/2 strutter. As I recall "The Sopwith Zoo" was the title.
I wanted a rugged, simple WW1 subject with wing area and simple struts, rigging and landing gear.
So far here we are:

Looks very nice Mike - appears to be electric power?  Do it up as a 2.F1 in colors from the HMS Furious' Tondern raid and you can fly it off the "carrier" at WESTFAC (http://www.tondernraid.com/tonder.htm (http://www.tondernraid.com/tonder.htm)).  There's a suitably grimy and subdued scheme for one of the Tondern Camels here:  https://www.scalemodellingnow.com/hnaircraftkit-wingnut-wings-sopwith-2f1-ships-camel (https://www.scalemodellingnow.com/hnaircraftkit-wingnut-wings-sopwith-2f1-ships-camel)

Progress on the Strutter has been slow as we wrapped up our Cub Scout year with the spring camping trip last weekend.  Spent a bit of time looking at the rigging, then added braces and tissue anchors to the wings for the aileron cables and control arms.  I glued in rolled paper tubes where the aileron cables go through the wings to connect the upper and lower ailerons.  Wings are ready to cut apart and set the dihedral.

Yea the tedium of putting in place all of the rigging points
has slowed me down also. I think Im going to do the RNAS #10 sqd
"C" flight that had the red and white stripes and the
checkerboard motif on the wheels. This is where it gets fun.
What scheme choice is yours?
I wanted a simple model, compact with tons of wing area
to quickly charge and fly.

Thank you for the explanation.. That's pretty well the method I use.
Embarrassingly  tho, I despite masking tape protection on the rib end,  have too often inadvertently  'hit' the ribs with my sanding stick. 
 A 1/32 rib doesn't suffer abuse gladly. Subsequently requiring a lot of time / patience and templates to laminate on rib repairs..  then reshape the airfoil  accurately.
Was hoping there was a previously overlooked solution.

Thinking thru a method to achieve a PC-10 look using tissue,
I chose to use white Easy Built domestic along with the Acad color pallet.

I printed off a number of small samples and decided that this
looked close enough. I printed 6 sheets of 81/1 x 11 and here

At my suggestion Ratz has pulled the Spitfire content into it's own build thread.  Now that the Spitfire is complete I'll be getting back to the Strutter, with perhaps a jetcat on the side...

Thanks Ratz for cleaning up my mess...

I mentioned in an earlier post that Kip Aero (https://www.kipaero.com/ (https://www.kipaero.com/)) is selling reproduction Sopwith aircraft and is currently building a Strutter.  They've moved the aircraft to a Dallas-area airfield and posted a nice time-lapse of rigging the tail and wings onto the fuselage onto Facebook:  https://www.facebook.com/KipAero/videos/2316400541753983/?__tn__=%2Cd%2CP-R&eid=ARCrUlWRUETlY2JtA3JTV5T4-mSAMvV-dr0R3tejCu0fuwd_y9mHKolkVvmu8l5zRo5hx26N2Fi3HFBk (https://www.facebook.com/KipAero/videos/2316400541753983/?__tn__=%2Cd%2CP-R&eid=ARCrUlWRUETlY2JtA3JTV5T4-mSAMvV-dr0R3tejCu0fuwd_y9mHKolkVvmu8l5zRo5hx26N2Fi3HFBk) 

Their Facebook page has a wealth of Strutter construction photos showing all manner of details of the structure.  They advertise that they build to original Sopwith prints - how close their aircraft are to the originals I can't say, but looking through their build certainly gets me pumped up to continue mine.

Cheers,
