PT Boats
« on: December 17, 2011, 11:39:50 AM »
So, if you don't already know, I designed a 1/48 scale PT Boat kit.

Based on the ELCO 80ft Class 103 PT Boat used in WW2.

The model is available at ecardmodels.com  http://ecardmodels.com/advanced_search_result.php?keywords=pt+boat&x=0&y=0

There are three variations of the Boat available:

USN Gray painted as it came out of the factory
USN Green as it was repainted for service.
Disruptive Camouflage (Zebra striped) used in limited numbers in both Pacific and European operations.



I have also produced two "conversion kits" allowing you to build two other versions
of either the Gray or Green models.
These are free kits, once you purchase the base model.



...

I originally had plans to produce at least one more version, a tri-colour camouflage paint scheme
but I have had difficulty nailing down an actual pattern and colour configuration for the model.

I am reluctant to use any of the scale model examples of camouflage paint schmes as none seem
to completly agree with Navy directives. In fact, Navy directives don't seem to agree with each other!

Anyway, this might be a future project.
Feel free to offer up any ideas.

and if anyone does purchse a PT Boat kit...
make sure you go to my Downloads Page

and get the updated part "Torpedo Propelling Canister"
for the Torpedo Tubes.

This was an improvement made to the kit after its release.

Everyday I see my green PT Boat kit sitting on the shelf,
and everyday I wonder what this Disruptive paint scheme will look like built up.
I keep hoping someone has built and will share some photos.
But it never happens.

So, the other day, I was between builds of the CL-41 Tutor
and I decied to print out the PT Boat kit and build it myself!

I'm not going to document every step of the build
and I can't say how long it will take to finish,
but I'll try to post some regular reports.

...
Elco 80ft Class 103 PT Boat in Disruptive Camouflage paint.

First step...and first mistake!
I printed out the four sheets of internal formers and laminated (spray glue) to heavier card.
The mistake was not pre-assembling the large deck plate parts and then gluing them to card as one large part.
Its recommended that you do that.



...
Anyway, steaming ahead, I assemble the Hull inner framework.
Pretty simple really, everything interlocks.
Just flush the top deck edges, don't worry about the bottoms/keel.

The spacers/stretchers are necessary to keep it all squared up.
It was a challeneg to remember how I positioned everything originally.
The instructions don't explain the exact placement of each block and spacer.
but to be honest, it doesn't matter, as long as they all get installed, glued into place, and everything is aligned and square.







...
Next I assemble the Hull (outer) from about? nine parts, plus a number of joiners and overlapping strips.
I started at the front, and assembled the lower parts, then attached the sides (from the front)
leaving the stern plate to the very end.

Its important to cut out the holes in the bottom of the Hull (for the propellor shafts)
and assemble, and install, the recess boxes for the prop shafts.





...
Once the Hull parts are partnered up and glued into place... I glued the horizontal ribs to the Hull skin...
then assemble and install the deck "supporting" plate. (I didn't photograph this part, sorry)
Center it and glue it to the inner structure.
Then glue the Hull skin to the edges.
Trim off excess, making the skin flush with the top of the deck (supporting) plate.
Then install the actual "deck".

The deck consists of a top and bottom layer...each assembled from two parts...
sandwiching a 2mm layer of laminated card.
The entire deck is 2.5mm thick and the edges will be wrapped with thin strips.

It is centered front and sides...the stern hangs out a bit further.

So, I forgot to take photos of the assembly, but I installed the splash gurad strips on the sides of the hull
and the finishing strips that go under the edges of the deck.

Everything is triple layered and glued into place.

I also hand coloured (black fine point marker) the deck edging, to match the hull stripes.
Everything is supposed to be handpainted, so its okay if stripes don't always line up perfectly.



...
I also assembled (three layers) the deck railings or whatever they are called...
curved them to match the location and edge glued them into place.



...
With the Hull basically completed, I can start adding things...
starting with the engine exhaust and mufflers, fitted to the stern plate.
There are six mufflers in total so it will take some patience to get all these small parts dealt with.

I also assembled the smoke/fog canister for the main deck.

Still plugging away at this PT Boat...between other work, and when I am bored...

Finally got one bank of Mufflers done.
Not too difficult, just five or six very tiny parts.
And that includes rolling some small tubes and cutting out very small layered parts.
Takes me about an hour to assemble one Muffler with all its parts...but its a tough hour! lol



So, I decided to switch over to the Prop shafts and Propellors (as well as the Rudders).
This time I used wooden dowels (as opposed to wire rods on my last PT Boat build).
I think the Wire was easier to work with.

And I mixed up the prop shaft supports...glued them all in the wrong locations...and then had to cut them off and build again.

I think I'll go back to Mufflers.



Oh, and I built the Day House and affixed it to the Deck.
No surprises there...built according to the Instructions.

I'm thinking the disruptive camo would give me a headache after just a few minutes of working on this.  Looking good, sir

No, its not quite that bad! lol

...
Still plugging away at it.
Between other projects.
Now that the latest Tutor Jet model (Red Knight) is done, I'll have more time to work on the Boat.

More deck structures done, including the Engine House and Funnel vents.



And the forward House/Cockpit...
and Bridge area, various Wall structures, and such.

One Turret in place...just started on the second one.

Been a while since I updated, but work still continues on the Disruptive PT Boat.
Progress is very slow now, but heres a catch-up...

I decided to put in the fore deck guide railings/wires that I left off of my first PT Boat build.
In photos, many PT Boats have this rope/wire removed.
Probably just got in the way for the crew.
Anyway, I made some supporting masts from toothpicks and used straight wire for the railings.
Unfortunately my wire lengths were too short to reach the bow point.
But since I am unsure of how they attached at the bow, I decided to leave it this way.



...
I assembled the big AA cannon and fitted it to the stern deck along with a few other deck bits.





...
I also finished up the Exhaust Mufflers/Pipes, etc



...
And, I got both Gun Turrets completed and added the upper Railings.
Instead of wire this time, I went with paper railings.
Yes, these are pretty small and thin...very delicate.

To make them I used the printed patterns provided for the wire railings and coated the prints with craftglue (PVA).
Once the surface was dry, I coated the back sides of the paper patterns.

And once dry, I cut out the printed railings, using a Hobby Knife (#11 blade)...very slowly and carefully.
I left a little bit of white edge so the railing lines were thicker.

Then I glued them in place...gluing one attachment at a time, and forming the railing into a curved and bent shape.

Next up I built and added more components, like:

Machine Guns and Torpedo Tubes



...
Radio and Flag Mast



...
Smaller details including the Torpedo Tube Firing Charge Canisters




...
And a Life Raft on the front deck.



...
I have two more Torpedo Tubes to build and install.
Thats about it I think?
Might be some other small details, but nothing too important.
Then I will take some final photos.

Well, I'm sorry to say, I still have NOT finished this Boat!
LOL
Now I am sidetracked with the Saladin Armoured Car build.

The Disruptive PT Boat ended up on the shelf, out of harms way, for the time being.
So, I snapped a couple of photos for the store listing.

I figured I might as well share those with you.
One day, I will hopefully get the other Torepdo Tubes done.
Maybe add some Depth Charges too!
