Cessna 172 Floatplane (1/20,Nichimo)

I blogged two other copies of this kit here on LSP. This third one will be considerably modified from what came in the box and be mounted atop a set of floats.

Parts are scribed on the Silhouette Cameo cutter using their free download software, Silhouette, Studio.

Slow and careful follow up with a #11 can help a lot in safely removing fragile parts after they've been scribed on the Cameo.

The wire segments are solidly CA'ed into each mounting position and then each wire is anointed in epoxy and slid into the tubes until set. The foam core jig holds it all in place.

Wallace approves.

The final paint scheme hasn't been decided yet.

Whiplines?

Generally, yes. These won't be the amphibious version, though. I was worried that wheels installed in the floats would be a weak spot and eventually have trouble holding up the weight of the model. I couldn't find any cross sectional views for Wipline floats, only the most general dimensions. So I'm calling these "Wiplineish". They're close but not perfect.

A fellow I found most helpful with anything “floatplane” is Larse Opland of Khee Khaa art products.

he helped me with all kinds of information when I was doing my Monogram models box scale Cessna 180/ 185 on floats...if you’re interested

Those parts turned out really well. I've been thinking of getting one of those. How thick of a sheet can it reliably cut? I haven't seen many people, if any, use one like that.

About 1mm thickness is the heaviest you can get a reliable break in the plastic. Most of the time I'm using it on 1/2mm and 1/3mm.

1/3mm is what's pictured above but the walls and main bulkheads of the float bodies are 1mm for strength.

An update to the Cessna. It may be a few days before I know how I'm going to go for the color of the interior. But there's a lot I can still get done if preparing the cabin for a maintenance diorama.

Replaced the kit floor (bad fit) with one which fits a little better.

This is how I'll be displaying the model, interior still in, but carpet and seats removed.

There were a dozen ways to handle the interior trim of the C-172. In this case I'm planning to go with a combination of hard plastic headliners and trim overlapping fabric headliners. (Early to mid-1970's style)

Examples of plastic panels over fabric liners.

Wow, this is really coming along, I love the look! I do so love seaplanes, and this is one that would be super nice to have on the shelf. 

 

As to the floats, I think using the Silhouette to scribe the first lines is an excellent one. It seems there are nearly endless possibilities with them these days. 

Do the floats taper at all on the tops? It seems a tiny bit blocky to my eye, but I could be thinking of other floats.

You gotta tell me where you got those instrument faces and what 2 colors did you use for that panel. That's the exact color of my customer's panel.

The instruments are just images stolen from around the internet, arranged carefully with Microsoft Paint (or similar program) and then printed at best quality to photographic paper.
The plastic sheet of circles was cut on an Silhouette Cameo cutter.

The older float designs often do have some degree of taper. But the modern Wipline brand have the same top deck width for their full length.

Additionally, I want to open up some of the inspection panels for the model.

Drill out the spot for the inspection cover and then add a small sheet plastic ring, cut on the Silhouette Cameo.

The blue stuff is a vinyl masking film called Oramask. I'm hoping to be able to use for for the inspection covers after it's been painted.
