The brand new Lukgraph resin/3D-print kit lands on my bench. I will build 46.37 known from two photos taken after an accident when the rear fuselage was broken. It is not known if it was repaired.
I started with the 3D print engine. The material is quite hard and brittle, it does yield to cutting with razor saw but the trees are vulnerable to breaking and in some cases small cavities in the elements are formed, which require filling, I use liquid CA glue for that. The 3D printed elements have visible print layers at some spots but a couple of sessions with primer and sanding can repair this to an acceptable level. I am at the third session now and it seems that the fourth one will be required.

I am still not sure how to approach the painting. Yet, I am quite sure that I will not dare to cut this engine into pieces. So probably a lot of tedious masking and brush retouches, which I detest, will be required.
-
Have my attention , been looking forward to this for a while now .
Engine detail is lovely but yeah , going to be tricky painting it :o
Alexis
-
I can see this kit will have its challenges.
-
A promising start and an interesting kit. Thanks for sharing Prze, I shall be following with interest.
-
What a super engine - an excellent start indeed. But I do not envy you painting it....although we all know that it will look extremely good when you have finished it.
-
A nice start on the engine. I guess the 3D printing process hasn't quite caught up with WNW molding yet!
RAGIII
-
Thank for your interest.
Right, Rick, WNW injection was surely of better quality. But even so, this is not bad. I managed to airbrush the majority and with some retouches with a brush the engine is quite decent I deem.

Prze,
Nice progress so far. ;)
The Mig one-shot primer - can lacquer based paints be sprayed over without reaction?
Cheers,
Bob

Thanks!
The Mig one-shot primer - can lacquer based paints be sprayed over without reaction?
I am sorry, Bob, I cannot answer this question because I use exclusively acrylic paints - Vallejo, Tamiya and Pactra.

I really don't understand why they did not just cast a resin engine. In this instance, I don't see how the 3d printing was a superior option. But you still did a beautiful job.

You have no idea how many times I have talked to Łukasz about 3D print quality, the difficulties with the engines printed as one complete assembly piece and another issues related to his kits.
But he decided for many reasons he had to make them like this. He is basicaly a one-person company and he has no resources to do it otherwise, while keeping the kit prices at a reasonable level, produce enough copies to be able to live from the income and offer more and more new releases.
Coping with these engines and the visible traces of 3D print are the price we modelers have to pay in benchtime for the pleasure of having kitted the subjects which most likely no one else will provide us.
As for me I am ready to pay this price.
-
And some steps forward.
The AD engine got its electricity and dirt.

(https://i.ibb.co/12ZPPR2/20220307-222924.jpg)
The exhausts and upper water pipe sections got sanded and airbrushing started. The exhausts had the outlet openings but they were too small so I decided to drill the out with larger diameter. Special care is required because the 3D print material is very brittle and if you drill too rapidly it is prone to crash. Drill veeeery slowly!
(https://i.ibb.co/WPJhFrJ/20220307-223021.jpg)
The visible edges of wood and metal panels around engine opening are being substantially thinned to be more true to scale. This new Lukgraph resin is very fine to work with, almost as soft as injection plastic. A sharp modeling knife and sand paper do their job.
(https://i.ibb.co/tz9wCGP/20220307-222832.jpg)
And cleaning of the resin and 3D printed elements of the cockpit is also underway. I will use the primer soon to check the quality of sanding.

You are doing your usual fantastic prep work Przemo! Looking forward to seeing the cockpit assembled and painted.
RAGIII
-
Thank you, Alexis and Rick for your continuous support :)
Here is more, I started some assembly of interior. Only a few bits will be assembled before painting wood to leave margin for easy manipulation with an airbrush.
For now, only a little trimming of engine fire wall and under-engine supports was necessary. The former was marginally too broad and the latter ones had too narrow gap for the engine block. A few touches with a knife and sanding paper and they fit nicely now.

Beautiful work on the engine Prze. I can imagine it wasn’t an easy paintjob, it being one solid resin part. I also like your choice for this kit.
I will be following with interest.
Willem

Some great progress here, Przemo! I do love the engine colours and texture- your touch is just so good! And Thank you for advice on dealing with the printed and resin parts - something I have yet to experience! Regards, Marc

I wholeheartedly agree with this! I’d happily buy kits like this and their BE2c and others, without any internal detail - no engines, cockpits, anything - and have to scratch-build or source those bits elsewhere, just to get these beautiful unique planes.
And you’re doing an amazingly beautiful job with this engine!
-
Thank you for your kind comments.
The work is progressing, I am with the paint job of the interior pieces, the photos will come soon.
-
Finally I have some photos to show. The innards have been painted, treated with dark wash, sealed and are being assembled. I have only added the HGW textile seatbelts, the rigging and control cables. There will also be added the throttle and ignition control linkages from the control levers.

It may be a bit more work, but once you have finished a subassembly it looked like you have build a WNW :o
That is damn impressive!
Wonderful work.

-
Thank you Bob and Frank. But Wingnut? It is too big a compliment, I am afraid.
Well, before going to bed I mounted the engine, the linkages and a fuel line are connected, too.
And I have just realized that the cockpit floor has to be lengthened to the rear because the crude interior joint of fuselage halves will be visible through the huge cockpit opening and it has to be covered somehow. Scrathing this extension will be the last thing to do before closing the fuselage.
(https://i.ibb.co/z5Qv1Dw/20220323-001437.jpg)
(https://i.ibb.co/mB2FKf8/20220323-001227.jpg)
-
She's looking beautiful Prze! I know nothing of the type so this is as much an education on the type as it is for LukGraph kits!
-
Thanks, Zac.
The rear floor imitation was prepared, the fuselage is closed, the seams are filled with CA liquid glue which is curing now.

Now my attention is drawn to the wings. Work on the lower ones is underway. Sanding paper of various grades is used to remove the traces of moulding block along the leading edges and on both surfaces where the layers of 3D printing of parent elements are very much evident - here the surface on the right-hand side is already cleaned.
(https://i.ibb.co/6821Rwq/20220324-173838.jpg)
And the full view where the wing below has still the untreated leading edge.
(https://i.ibb.co/58BfQXc/20220324-173915.jpg)
The resin quality is acceptable, I have already commented it is not too hard. And there are very few air bubbles, actually I have done only 5 plastic inserts on those edges where the wings were attached to the blocks - I will show them in the next photo session.
-

I have a first- or second-generation 3D-printed kit (WW2 subject in 1/48) which is long-stalled due to having to sand the rather large print layers. Mine are much more drastic than seen here so that gives me hope that it'd be much less prep work to tackle a LukGraph than I anticipated - thanks for sharing your progress, Prze!
-
The interior look Gorgeous in the closed up fuselage. Thanks for showing the detail shots of the clean up needed to remove the printing layers.

Thank you, Zac and Rick.
The cleaning is progressing.
The lower wings ready for primer, with white inserts at the drilled out air bubbles.

(https://i.ibb.co/1TQrh4L/20220328-220705.jpg)
The upper wings still need the leading edges polished after embedding the inserts.
(https://i.ibb.co/YXD9D4c/20220328-221009.jpg)
The tail is polished, no air bubbles located.
(https://i.ibb.co/SKgCgFF/20220328-221300.jpg)
Ailerons and horizontal stabilisers with elevators are waiting for their turn.

And one wheel ready compared with the other one still in the crude state.
(https://i.ibb.co/d7vP4Bc/20220328-221123.jpg)
Waterproof sand paper of 360, 600 and 1200 grades is used extensively ;)

Fuselage is super ! Love the wood tones through out . Clean up is coming along great , nice to see not many air bubbles .
Alexis
-
Thank you, Alexis. Though later I found more bubbles that required treatment... ;)
The tedious work on bringing the elements to appropriate surface quality is apparently done. The primer does not reveal any other issues. Now it should be easier and more pleasant... ;)

Thanks, Rick. The airbrushing is closer and closer.
I have prepared a cardboard jig and attached the lower wings with 3.5 deg dihedral and 2 deg sweepback at the trailing edge. The seams must be filled, some work is still required.

Great progress, the "wood" looks nice.
What brand of white primer you use on resin? Does it "bites" into the resin?
Cheers,
Frank
-
Thanks, Frank.
I have shown the primer bottle at the beginning of my thread. It is Mig One Shot Primer. I did not notice any interaction with the resin. And if you possibly refer to that zone on the upper wings where I had a technical break in wood application, it is mostly the play of clear brown shades/intensity and the semi gloss/gloss surface. It will all be varnished and unified, after decaling and wash. ;)
-
Airbrushing complete. Decalling under way.

Very good work Przemek! Will you be with this kit in Bytom?
I may just be on time. Now it depends mostly on how good the fit of struts will be. If I have to correct their length, I will not finish this model before Bytom.
And for the time being - the wash done and varnished. The bits are basically ready for the final assembly.

The brake installed. And 4 main interplane struts are being attached using a funny ad-hoc installation of several bottles I had at hand and a heavy spool of soldering wire as a weight to keep the geometry of the upper wings which for now serve only to keep the struts geometry.

What a nice wooden biplane!
Thanks for answering my question regarding the primer, I have overlooked the picture before.
I asked because there used to be a special resin primer from Gunze, but I haven't found it anywhere. If it works as well on resin as the Metal Primer from this company does on metal parts, then I would have liked to test it.
Masking on resin can be risky if the primer does not adhere well enough.
Cheers,
Frank
-
Thank you, Willem and Frank.
Frank, it seems that this primer holds to resin perfectly. I had no problems with masking, no paint peeling, so I can highly recommend it.
And tonight I finished my Lloyd. A few photos here, the proper gallery will come soon.
