Title: Scratchbuilt Patrol Torpedo Boat - Semi scale PT 109
Post by: VC on January 16, 2012, 03:42:51 PM
For as long as I can remember, the Torpedo Boat has been an interesting subject for me. Particularly the World War 2 types. Way back in 1991, I had modelled the Brave Borderer which was based on a Vosper boat.

Due to all the hype, thanks to its one time skipper John F. Kennedy, the PT 109 (Patrol Torpedo Boat) is probably the single most famous boat of its type.

Here is my completely scratchbuilt PT 109. Scoured the net but found no workable plans to download. Gathered a whole bunch of photographs and got down to work.

She is built to a rough scale of 1:50 and measures approximately 19.5 inches. The original Elco was a 80 footer. Hull is made from balsa sheet and planking. Superstructure is made out of Sunboard foam sheets.

Each and every component of the boat is scratchbuilt (other than the electricals, the decals, the props and the stuffing tubes).

Particularly proud of the .50 cal twins, the Oerlikon Cannon, the Balsa Lifeboat and the Turret Railings. These four were tough calls!

Two brushed motors rated at 25,000 rpm, Single Brushed ESC rated at 30 amps, Turnigy 2 cell 2200mah battery (kindly modified from a damaged 3s by a fellow forum member), Hextronix 9 gram servo, Will be using a Futaba 2 Channel Tx/Rx.

Some detailing work still remains and should be completing them shortly. Water trials within this week. I have placed the battery astern to see if I can recreate the ‘bow up’ attitude of the PT Boat, at high speeds.

Not too happy with the final paint finish as the gloss mars the authenticity. I would have preferred a matte finish.

If anyone is interested, I can post a detailed build log of the boat. Let me know.

Thanks Gentlemen.

Lt. Col. Sundaramvelar thanks a ton for repairing / modifying that and the other LiPo's.

Wing Cmdr. Augustine, let's not get into comparisons as that is a relative issue. IMHO, Roopesh is in a different league altogether when it comes to scratchbuilding. It would be unfair to compare him with ANYONE. He is a genius.

hi VC
very nice build there mate.  :)
at least it looks like your's is getting a water trial................. mine is still 'high and dry' at the moment  :):):)    still to have the weathering finished and warmer weather to try it out.
I have sold all my rc gear now  [except the boat and radio] as I can no longer aford the hobby. but I may still build the odd boat for the g/kids..... see if the interest is there first....... the yellow one my g/son has is still sat on the shelf..........
happy sailing, I will drop by from time to time to see what everyone is up to :)

Don my friend,

Affordability, yes that can prove to be a stumbling block for all of us. Why do you think I choose to scratch build instead? Also living in the UK is a double edged sword. Whilst you do get a lot of stuff out there, it may prove to be rather expensive. I've sent you a PM, please respond.

I am saddened by what you have mentioned here.

Thanks a lot for your encouragement.

Regards,

VC

Can someone please think out of the box and tell me how to make the life belts? Roopesh are you there?

I was thinking of aluminium washers 'fattened' with M Seal. Anybody else has a better idea? Prop saver rubber bands are too big for the scale. :banghead: :banghead: :banghead:


Title: Re: Scratchbuilt Patrol Torpedo Boat - Semi scale PT 109
Post by: Swapnil on January 17, 2012, 12:47:21 PM
How about this: Cut a cylindrical wire/ cable (of required diameter) in lengths equaling the required perimeter of life-belts. Then join the two ends using using 5-min epoxy.

To get a good cylindrical shape, wind it around a cylindrical object and then join the ends with epoxy. Also try smearing a layer of epoxy on the cable surface for shape retention.

Post by: roopeshkrishna on January 17, 2012, 01:51:39 PM
Good after noon VC Sir, it is easy to make life belts..i have usually two options..take some high guage soldering led, and round it over a cylinder up to our size..join tips with industrial cyano..can paint it later..

another easiest option up to 1:55 scales is, can buy the washers for N C V s, ( Needle Control Valves), used in high pressure L P G stoves. can purchase in many diameters from 6mm to 18 mm..is cheaper..20 Rs for a packet..the main valve washers also do the best..
for bigger crafts we can use the "O" rings for bobbin winders of a sewing machine..

Thanks Roopesh. I had used the flux solder wire technique for the turret railings but it proved to be too soft. I had to rip it all apart and redo it during stronger wire.

The Life Boat. Originally constructed out of balsa, this miniature was made out of cardboad and M-Seal. The oars were a  :banghead: experience. Especially when your finger tips are caked with hardened CA! :giggle:

Post by: VC on January 18, 2012, 10:58:43 PM
Not yet Roopesh. Finishing touches are still being added as I write this.

Found a way to improve the shape of the life belts.

1. After the ends of the wire sleeving have been joined, let them set for a while.
2. Roll them around a pen barrel to achieve the initial shape. They will be hard and won't
   take up a perfect shape. Tha's ok for now.
3. Remove them from the pen and place them on a plate.
4. Now use a hair dryer to heat them and they should soften up a bit.
5. Now slide them back around the pen barrel and shove them into ice cold water.
6. Remove them from the barrel - BINGO! Perfect circles! ;D

Post by: VC on January 20, 2012, 01:39:55 PM
Thanks Swapnil! Yes it had become an obsession towards the end. Regular late nights - working upto 3 am almost every day. To think that I had built the hull skeleton almost a year ago and had junked it in a pile. I feel good that she has reached this shape today. Wish me luck for the maiden.

Just one question for all out there. If I don't add an external whip antenna (that will spoil the scale aesthetics), what kind of a range can I expect if the Rx antenna lies coiled on the deck? I plan to use a Futaba 27mHz system.

Thanks.


Title: Re: Scratchbuilt Patrol Torpedo Boat - Semi scale PT 109
Post by: Swapnil on January 20, 2012, 01:44:33 PM
I had once (during testing) left the antenna wire coiled on my hovercraft and did not have any glitches for 100 ft.

Title: Re: Scratchbuilt Patrol Torpedo Boat - Semi scale PT 109
Post by: greatguns on January 21, 2012, 11:20:02 PM
I suggest a little modification to Swapnil's idea. From d pics it seems VC is using single or tripple strand copper wire. Instead of drawing out the wire completely, draw out about 5mm and poke it into the other end, this will make the join stronger and the copper wire inside will keep d rounded shape intact.
As for the boat, VC is exceptional in scratch building as usual!
Keep up the good work. VC, u r inspiring me to finish building my boats!!! ?????


Title: Re: Scratchbuilt Patrol Torpedo Boat - Semi scale PT 109
Post by: VC on January 21, 2012, 11:31:05 PM
Me inspiring you??? Good joke Sir! Since I've learnt so much from you (still learning). I know your level of scratch building. It is a pity that you don't post any pictures here, had you done it, the levels of boat building / scratch building would have gone into hyper space. Modesty has a level - you exceed it many times over.

Sir, I tried doing exactly that (raw out about 5mm and poke it into the other end) in fact two of the belts that I plan to attach on the cabin cruiser Naughty Cal, are made that way. The ones attached to PT 109, were joined using Industrial CA and fixed immediately to the superstructure so that they don't lose shape.

Thanks Sir!

Post by: VC on January 23, 2012, 02:53:48 PM
Tested her in water. Two improvements to be incorporated. Some ballast required on the starboard side, slight list noticeable. Waterline has to be extended up by about 8 mm. Initial test run was satisfactory. I have to now get the motor shaft and prop shaft perfectly aligned and then epoxy the motor rack to the hull.

Must find a way of extending the antenna without spoiling the scale appearance. Any suggestions? What is the finest wire that I can use?


Title: Re: Scratchbuilt Patrol Torpedo Boat - Semi scale PT 109
Post by: VC on January 23, 2012, 02:59:09 PM
One major lesson that I've learnt from building these boats is that all ship modellers need to have access to some kind of a testing tank in their premises. This will allow us to trim the builds for better performance. It is a frustrating experience to find listing or incorrect draught on a model after travelling a considerable distance to a pool or a pond. The testing tank can be as simple as a pit dug in the ground covered with tarpaulin or plastic sheeting or else a tin tank that can hold 6 inches of water and sufficiently large for the boat to be contained in it.

After months of waiting, maidened her yesterday with disastrous results at an uncharted pond. She proved to be a beautiful ripper on the first two runs. Bow rising menacingly from the water at half throttle. At three fourth throttle she was almost trying to get airborne. I became overconfident and took her to the extreme end of the pond and turned her around for a high speed approach and pass. Midway down, she ran afoul of some underwater weeds and remained stuck despite all efforts to free her. One of the local urchins jumped in and forcibly ripped her out. One prop destroyed. Then as he swam with her, he dropped her nose first into the water and she sank with a fully charged LiPo. She bobbed back to the surface however, and I was able to disconnect the battery. Some of the extra detailing has been destroyed. It's back to the build again.

As far as performance is concerned, I couldn't have built a better Torpedo Boat. Pity that even though I had a camera at hand, I wasn't able to capture the action.

Lesson learnt: Don't ever sail a boat in a water that is unknown and make sure you have a rescue system ready before you sail.

First of all sir, superb soundtrack... very fun to listen oldie goldie Jimmy Dean's work... Already downloading Youtube track..

The craft is also stable and the abrupt turning is eye-catching... Could you explain how you achieved so sharp turns....?

Thanks Adi, I could attempt to give you a technical/lengthy explanation, but I would rather be honest - NO IDEA! ;D

Jokes apart, I guess the hull shape and the twin motors/props/rudders did the trick along with the correct CG and balance. I deliberately made the craft sit low in the water to achieve the correct profile, however, water seepage through the rudder tubes proved to be a problem. Ripped the whole thing apart and remodelled it.

The boat looks really stable and quick. The turns are amazing. I really agree to Adi..that there must be any principle to achieve this which we don't know to be exact. Anyways VC sir...Its great for me to come back on the forum starting from your thread. You are an artist....and...I like to read and see your work. There are some people on our forum who really make RCI a wonderful place to read and learn anything from water to air. And you are one of them....

Thanks.
Cheers.

Perhaps there is IS a secret behind her manoeuvrability. My Mother spent hours working on the hull - sanding, patching, M Sealing, sanding. She knew what this boat meant to me. She was my biggest supporter/fan. She left me forever, without any warning, suddenly on 24/11.

Perhaps, she is guiding the PT 109 through its fast turns and manoeuvres. I am just the the TX operator. I won't/can't claim any credit for the stability or performance of this boat.

I'm sorry but I didn't intend to share my grief in public here. However, here it is. I miss her so very much, and I can't get over this now, and probably, never will.

I guess it is OK to share this with the members on this forum. She knew what www.rcindia.org meant to me as I would update her with all relevant details posted on the forum every evening and she would absorb all of it. In fact, she shot my first Hovercraft video, running after it on its maiden run with the digi cam. Sweetheart Ma.

Band of Brothers.................I would request you NOT to comment on her demise with condolence messages or R.I.P. messages. Just let it be. Let her rest.

Comments on the boat and her performance are welcome. Let's leave it at that.

Thanks Chotu. It is the detailing and the scale accuracy which is of paramount importance to me. I don't want to build a high speed craft with inaccurate scales and ratio/measurements in 4 days. I would rather attempt to maintain scale accuracy (afap) and will take my time over this.

VC sir, I tried building this boat in my dreams, i couldnt.....I can only assemble n programme helis..

But building a boat from scratch is something exceptional which u did..Hats off.

Doctor, thank you for the kind words  :bow:. Scratch building is often portrayed in an exalted manner by some modellers. It is not all that difficult as one can be a little lenient as far as design and dimensions are concerned. We don't have to stick to the "exactness" of a plan. However, scratch building a model to scale and keeping it as close to the prescribed dimensions of the real thing is a different ball game. If one attempts to add to it realistic scale detailing and markings then he is asking for sleepless nights, especially while residing in a non metropolitan city/town in India. :banghead: I spent a week fruitlessly searching for someone to paint the '109' to scale on the gun turrets and then decided to have stickers cut out - and they are NOT to scale.

This baby was a real experience after the hovercraft builds. Whew!

Great detail very well done  {:)}

Only 1 thing I could pick on and that is the angle the shafts they are to step, the lower the angle the better the performance
one rule I follow when building smaller subsurface drive boats is get the prop as close to the hull as I can and have the prop about 10mm from the rudder

Other than that a great model

Post by: VC on June 23, 2013, 02:21:13 PM
Thanks Stuart!

Will keep this 10mm thumb rule in mind for current/future builds.

I have posted some yachts for you to look at built by some members of the model boat club I am in


Title: Re: Scratchbuilt Patrol Torpedo Boat - Semi scale PT 109
Post by: VC on June 23, 2013, 02:37:32 PM
Thanks a lot, however, you will notice that I haven't commented on the yachts. Reason being, graceful as they are, building yachts / sail boats doesn't appeal to me. I am more the Torpedo Boat, Frigate, Cabin Cruiser types.

Nonetheless, thanks again.

I understand that I'm the same I find yachts a bit boring just posted as they are very beautifully built boats

I love warships, cargo, high speed boats and hovercraft
 I have 2 yachts which I take 1 to the pond once in a while and yet to finish the other probably never will been on the shelf for 15 years lol

we have a member that builds awesome warships and subs he is away at the moment so when he gets back from holidays I will get some pics he is another brilliant builder
his warships are fighting capability with shooting gas filled torpedoes exploding depth chargers and missiles that shoot about 50ft into the air
 we also have some huge warships that are 6 meters long I will find the photos and post them for you

There was so much interest still in this thread. It had reposed in the dusty archives, but when brought out again, was a hub of discussion
