1/32 Scale Lindberg Pt Boat Rebuild - R.C.

PT Boat Rebuild = 1/32 scale Lindberg Kit #2

Looking good Peter. Really like your calipers too Look like a nice set.
Ingenious use of spares for the radar.
James

Ahoy there James.

Thank you. Those calipers are ancient but they are great to use to square off boxes when gluing them together. The calipers are also goof for applying a bit of pressure whilst the glue on some parts such as the lower radar mast assembly cures.

Cheers from Peter

40 mm Bofors Gun and Ammunition + Ammunition Clips

Ahoy there interested parties.

A PT boat carried a lot of different weapons at different times. As targets changed from anti-shipping to barge hunting more guns were added to deal with the barges. One of the guns commonly used was the 40 mm Bofors gun that was usually mounted on the aft deck of the boat where the 20 mm Oerlikon cannon was mounted on the early boats. However, there were a few boats that mounted the 40 mm Bofors gun on the foredeck.


Here's the background as to why my model has a 40 mm Bofors gun on the foredeck.

First off, I am *NOT* attempting to model any particular boat as it appeared at any particular time.

When I built this model over 20 years ago I had on hand an old 1/32 scale Revell M-42 Duster model that I no longer had a use for as i had bought the 1/35 scale Tamiya one. Looking at the Revell model I decided that there were a number of parts that i could use from it on my 1/32 scale Lindberg PT boat. Those parts included a few pieces of the 40 mm Bofors gun. I had to heavilly modify the twin gun to get a single gun out of it and I scratch-built most of the rest of it. Over the years the gun has suffered some damage and is also being restored.

Now, I'm one of those fellers that likes to pose my artillery in use. Thus I needed some ammunition for the 40 mm Bofors gun. I took a chance and bought Mini Art's 1/35 scale Russian 45 mm Shells with Ammo Boxes set. Sure enough, the 1/35 scale 45 mm ammo is almost perfect for a 1/32 scale Bofors gun. Here're two images of the Bofors gun with a shell in the feed.






With just a wee bit of filing of the feed guides the shells will be a perfect fit.

What's great about this Mini Art set is that you get 30 of the type of rounds the Bofors gun used. You also get 12 spent cartridges. There are an additional 30 rounds that are not the type used by the Bofors on PT boats but they can be cut down to make 30 more spent cartridges.

Another neat thing is that the strips that go into the ammo boxes to hold the rounds in place are very similar to the type of clip that held 4 of the 40 mm Bofors rounds. Each 40 mm ammo clip held 4 rounds. The pieces in the kit are made to hold 5 rounds. Cut off one round section and I have a 4 round clip. This means that there will be lots of extra clips to go with the spent cartridges. Neat huh?

Here's an image of those pieces that I'll use as ammo clips. You can also see the ammo and spent casings that I'll use with the Bofors gun.




Finally, for this update anyway, here's an image of the Mini Art 45 mm ammo kit box and the ammo in it. One set gives me 7 full clips of ammo and a partial clip with 2 rounds left in it. The 2 rounds clip will go on the gun as if 2 rounds have been fired. The possile total of 42 spent cartridges will allow me to model the gun on the boat as if the gun has fired 10 full clips and 2 rounds from the clip in the gun.




I need to rebuild the broken elevating and traversing cranks for the gun. The gun also needs 1 new rear sight ring for the left side. Plus I need to add the rack at the back of the gun platform that protected the loader from falling off the platform and that also held some ready ammo clips.

Next up I'll tell you how I used the 1/32 scale M-42 Duster road wheels and Tamiya 1/35 scale fuel drums to make 10 depth charges for this boat.

Comments are welcomed and encouraged. Thanks for looking and/or commenting.

Depth Charges

Ahoy there me hearties.

PT boats relied on stealth for attack and then speed to get out of any sticky situations. These boats were no match for a destroyer. Except... It was found that a depth charge, set to explode at a shallow depth, if exploded under a pursuing destroyer could "break that destroyer's back" thus sinking it. Therefore as the war progressed the aft torpedo tubes were removed and depth charge racks were installed there instead.

I decided to have 8 depth charges on my boat - 4 per side. Since I'm also part Scot* (and thus very frugal LOL) I decided to scratch-build facsimilies of depth charges. Once again I turned to my Revell 1/32 scale M-42 Duster donor model for some of the needed depth charge parts; namely parts for the ends of the depth charges where the depth settings were. I used the Duster's outside road wheels for these ends. Here's an image I found on the web of a Revell M-42 Duster that shows the road wheels quite well.



Okay, I now had reasonably good parts for the ends of the depth charges but what would be good for the depth charge bodies? How about 1/35 scale Tamiya fuel drums? I had lots of those.


Here's an image of the unassembled Tamiya fuel drums and 3 completed depth charges.




So, I assembled the Tamiya fuel drums and after the cement cured I sanded off the bands around the drums and also any other detail on the drums or on the ends of the drums.

Next, I cut out the center section of the Duster road wheels. After doing that, I drilled the same size hole into each end of the 8 depth charges. Then it was a simple matter to cement each road wheel center section into the depth charge end as shown in the middle completed depth charge in the image above.

There is another way to make the ends of the depth charges and that method uses a stiff metal foil. The foil of a yoghurt container is ideal for this if you first smooth out the foil. Find something that has the pattern of bolts you want for the depth crage end and make 1 depth charge using it. Next simply place the foil over that end and rub it down with a soft piece of wood. That will give you a negative of the part. Flip the foil over and cement it to another depth charge that has a smooth end on it. When the glue has cured trim the foil to size. See the finished depth charge on the right in the image above.

After the depth charges were made I used one of them to determine the needed size for the 8 depth charge racks. I scratch-built the 8 racks from styrene sheet and styrene strip. Here's an image of the 4 empty starboard (right) depth charge racks.




Here's another image of those racks but with the depth charges positioned in them but not yet fastened with the restraining device.

I read once that Scotch was invented to keep the Scots from ruling the world, maybe it was Whiskey and Irish...anyways.. Great imagination, really like the resourcefulness Peter

Very cool. Some great info on the depth charges there too. I never knew that.

Ahoy there.

Got the radar assembly attached to the model.

Here are a few images to show what the model looks like now.

Side view without the depth charges.




An overhead view looking aft from the bow.




A view looking forward to the cockpit.




A view of the alternative 20 mm Oerlikon cannon without a gun shield. The gun shields were remove almost as soon as the boats arrived in theater. The 20 mm cannon shield weighed 250 pounds. I imagine it made swinging the gun to and keeping it on target hard.

The two other items in this image are the two spent cartridge bags I've made. One is for each gun on the two different models I'm concurrently working on. The gun without the shield will be swapped for the one 20 mm cannon with the gun shield thay is on this boat now. I'll use the cannon with the gun shield on my new build.




Thanks for looking and/or commenting.

Ahoy there James.

Thank you for your interest and comment. I should remind you that i have two threads going concurrently. One thread deals with this rebuild and the other is a completely different build of another 1/32 scale Lindberg kit I haven't finished yet. The new build thread has images of white parts. You didn't get the two threads confused did you?

Thanks again and I should have another update soon.

Ahoy there.

Sea trials today.

I took the model to another nearby pond today because my favourite pond always has major radio interference from something. This other pond is pretty good and doesn't have the radio interference problem.

Unfortunately the videos I took whilst trying control the boat too didn't turn out. Here a re three images of the model on the water.

I should mention that the radar mast is canted slightly aft but that's only because I forgot to bring the locking pin to keep it upright in its proper position. I think I discovered something else to model - a cable/rope to keep that locking pin from getting lost.









I got paint on the .50 calibre guns and on the 20 mm Oerlikon. I've also attached the 20 mm magazine and the spent cartridge bag to the Oerlikon. Here're 4 images of the 20 mm Oerlikon, without the gun shield, on the boat.










Thanks for looking and especially for any comments. Comments are the encouragement we need to keep posting stuff. VBEG LOL
