AMC DH.2 - Wingnut Wings 1/32

[Rafael Berlin]

Thank you so much to all of you for your kind words. I'm very happy that you like it so much. 
Hopefully tomorrow I will send some pics from the motor.

Best regards

Awesome work, Rafael.

Hello everybody,

as promised here are the pics of the motor. Please tell me, if it is too detailed. I have the feeling that most construction reports show more or less final results from major steps and not the way to the result.

But OK. This is how the WingnutWings part looks like. Missing material, but 2 spark plugs per cylinder in order to be prepared for different motor variants (Oberursel U1 has spark plugs at the rear side).

I decided to try the Taurusmodels Gnôme Monosoupape, which is a model of its own with approximately 90 resin parts

Direct comparison...

But take one step back. The cylinders were primed glossy black. Afterwards they only have been sprayed with Alclad 2 Aluminium more or less directly from above and from the under side. So the gaps between the ribs stay dark.

Excellent fit of the parts

Now for the valves. Valves, rocker arms etc are all made from individual parts. You don't have spare parts, so you have to be very careful.

2 valves are displayed open, others clothed

The rocker arms are extremely fragile.

My method to cut them off the sprue: First cut it off with lot of the sprue material. Afterwards make several orthogonal cuts. Now you can cut off the remaining sprue in little squares

Assembly. They clip together and are movable. I painted them black and drybrushed them. The color kind of fixes them.

Here are the spark plugs. Later I changed the black color to white, because of a photography in the WnW instruction. Both variants seemed to be common, but I like the contrast a little bit more.

Cylinders with valves (one open, the other closed) and white spark plugs.

Some parts are really tiny as for example the following one. I lost 2 of them and it cost literally hours, to find them again. Lukasz, please add some spare parts to future models!!!

It directly fits on the rocker arm. Movable!

More small parts. Put the silver joint heads into gold openings. Then assembly. Decals are from the WnW kit.

For assembly with the aircraft the WnW shaft has to be cut ("muss weg"). The radius at the shown place is to large ("Radius zu groß"). Needs some adjustment to fit to the Taurus.

Modified shaft glued to the Taurus motor:

Put in all cylinders

As already mentioned, everything is still movable (or removable). Rocker arm removed, rod glued to the tiny joint part.

Put it back into place...

... and glue it to the other joint:

Several hours later

Now for the commutator. Made from bakelite. Ir sprayed first a layer of desert yellow and afterwards a layer of clear orange (both Tamiya). I added some black pigments for the structure.

For the electrical connections I did NOT use the parts of the Taurusmodel, but some nickel silver rods 0.2mm from Albion alloys. Afterglueing, they were blackened and afterwards painted with brass color.

Dry assembly:

The commutator plate has a nice side (which you have seen) and a not so nice side with some glue points. For the final model I will change it in a way that the unfavourable side faces to the frame and will not be seen in the later airplane.


For wiring I used single wires from an old monitor cable. Wrapped them around a 0.2mm drill and slightly pulled them apart

That is not too detailed: it is inspiring! That assembly must have taken you hours and cost a great deal in patience. Brilliant modelling.

You can never have enough detail , all depends how far the rabbit hole you are willing to travel ! Beautiful job on the rotary !

Okay, it's official now.

I'm going to take up knitting...

This is Champions League modelling. Showing all the construction steps is very helpful, please continue this way!

Wow, Rafael. This is mind-blowing. These tiny parts.... incredible. Please go on with your detailed step by step construction thread it could never be too detailed.
Chapeau,
Manni

[Von Salza]

As for me Your report is perfect and seems to be a guide for beginners, like me.
So, please, don't stop

[PrzemoL]

Lovely job on that Gnome Mono. But you should try Taurus Clerget engine once. It has almost 300 elements...

[macsporran]

Inspiring stuff, Rafael - you have the patience of a saint.

I'd be doing a "Ballistic Bob" with those millimetric parts I think!
