discussion Richard's Revell Ex-Matchbox 1/72 Victor Resurfaces

Thanks Vaughan, little things creep up that needs attending to if only I had done it years back. I guess I'm a bit braver now.

Cheers,
Richard

Richard .
So small a piece of detail, but the effort was well worth it and what a result. Takes the model to another level .
Well done .
John .

Thanks Herr Rubblemeister, you know that little itch in the most awkward place sometimes needs scratching or it can be excruciatingly irritating. I've always wanted to do that to wing tips.

Now there's another little itch in the shape of blades on the tip of the refueling pod...



The kit blades are just too thick and are not even box like for pre flight covers.

For reference only

They look like the above that is until I saw the prototype Mk20B 10 bladed constant speed Dowty Rotol version that was briefly used at the beginning and was replaced by the later 2 bladed Mk20B

For reference only

I'm not into total accuracy and not sure how long it was in service but I am interested in the 10 bladed nose for one as now most turbo props are Rotol designed with 6 or more blades.

So it begins with cutting the knobs off... I'll be using thin pla card for the blades and gluing them all round at an angle.



Cleaned up the point and will essentuate the gap to the pod by sawing it lightly...that's it so far.

Cheers,
Richard

Hi Richard
Those lights look brilliant - pardon the pun. Drilling the bulb was clever. On with the many blades.
Jim

 

[rtfoe]

Thanks Jim:smiling2:, will get cracking tonight cutting the blades first...20 pieces.

But before that there is something I'd like to share, in my hastiness I applied the stencil decals without a gloss varnish coating so slight silvering occurred after copius amounts of decal softener and set. In the end when it dried I used commercial thinner(cellulose) and applied with a small brush... the silvering disappeared. I'm guessing the paint dissolved and blended with the decal film. I'll take a snap shot of the after effects later.

Cheers,
Richard

Richard,
The lights are a great improvement. Looking forward to see what you do with the propeller

 

[Fernando N]

The wingtips look great definitely worth the effort Richard.:thumb2:

Good luck with the props on the refuelling pods.

 

[BigGreg]

I'm really not into flying things.... but your paneling and your details are really SPOT ON.... well don Richard

 

[rtfoe]

Hi Guys, thanks for thereply and comments...

Paul and Fernando...I will press on to the propellers for the pods. Have cut the individual props and glued them today...pictures below...
Greg, same principle in building but with wings, flaps and ailerones instead of tracks with a lighter touch on detail and painting. Glad you're with us.

Clean up, slicing of 20 blades and finally assembly...





A while back I mentioned about showing a shot of the decal stencilling after treatment...here it is...



No more silvering and carrier film visible.

Cheers,
Richard

Lovely neat work those impellers are a great improvement.

 

[rtfoe]

Thanks Paul, painting them soon...they kind of look like mini turbines.

Cheers,
Richard

they kind of look like mini turbines.

That’s because that’s exactly what they are People tend to associate the word “turbine” with something like this:

However, this is also a turbine:

Anything that begins to spin because of a flow of fluid around it (gases like air are a fluid for these purposes), is a turbine. In an application like on your model, the turbine is probably more likely to be called an impeller, but that’s really just a description of its purpose rather than what it is.

Richard - Turbines, impellers, whatever you care to call them, they are a very neat bit of modelling and improve the detail no end.

Excellent stuff.

Looks to have worked. No damage to the decals? Did you just apply it to the decal and then allow it to dry naturally or did you rinse it off?

Thanks Guys, I learn something new everyday. The reason I used the word turbine is because the pod propeller was listed as a Ram Air Turbine on the pod instruction manual attached here...and like many people assumed it worked like a turbine...



Dowty Ltd were propeller makers and developed the constant propeller adapting the Rotol design which looked like turbine blades. It acts like the windmill you showed that works the hydraulic pump. The impeller would have been used internally to increase the performance and flow of the pump. Interesting that these three, propeller, turbines and impellers work using blades.

Thanks Ron...whatever it is this extra detail shouldn't be on this late a model of the K2 as it was replaced by the two bladed prop at prototype stage. Just thought it looked cool and wanted to be different.

Here it is painted...

Hi Jim, with a small amount of thinner at the tip of a small sharp brush, I applied carefully around the edges of the decal film and let the thinner work itself under it. I try as little as possible not to disturb the paint. I leave it and let the thinner evaporate cos its so little...just enough to let it seep in. You may need to use the thinner that's made for the type of paint you use. Mr Color reacts to lacquer thinner easily and maybe thats why it worked.

Richard

Ok finally after three years panel wash is applied. I use my very own water colour mix of black and brown with a drop of detergent. With this mix I spread it liberally along the panels...



It looks scary after all the trouble painting the individual panels...after letting it dry for one to two minutes I wipe with a damp cloth in the direction of the airflow.



I did this section by section as can be seen below...



The final outcome only for the top. I will spray a layer of matt varnish to protect the wash from rubbing off before proceeding to the underside.



After this more weathering like chipping, oil stains and streaking. Hope to finish this to start on the Toon build.

Cheers,
Richard

Richard,
Stunning work mate.

 

[rtfoe]

Thanks Paul, glad you like it. Definitely looks different than the first picture taken three years back with the wrong colour on.

Cheers,
Richard

The reason I used the word turbine is because the pod propeller was listed as a Ram Air Turbine on the pod instruction manual attached here...and like many people assumed it worked like a turbine...

You’re entirely correct calling it a turbine, because it is It’s driven by airflow resulting from the aircraft’s speed, in the same way a windmill is turned by air blowing past it on its own accord.

Interesting that these three, propeller, turbines and impellers work using blades.

An impeller is a turbine The word just means it’s used to drive something, whereas “propeller” means it’s used to move something forward. In both cases (turbines/impellers and propellers), the blades are usually airfoils,* like an aircraft’s wings. In the case of an impeller, the air (or water or hydraulic oil or whatever) flowing past the blades causes them to move, turning the shaft; in case of a propeller, an engine turns the axle that the propeller is on, causing it to move through the air and pull itself forward just like a wing lifts the aircraft up.

TLR version: you were exactly right in thinking the thing at the front is a turbine

Did I mention you vastly improved it over the kit part, so it looks much better now? I don’t think I did. You vastly improved it over the kit part, so it looks much better now.

* Although, like in all airfoil applications, a flat plate angled upward with respect to its forward direction should also work, but not as well.
