Does Jeff have any thought to producing these in 1/48 scale?

Cheers!

Mr Davidson should also give a thought about producing a set of deck hatches and frames as 3DP parts,would surely be appreciated on both sides of the Atlantic...[:-grin-:]

Man, I wish we could get some running lights and air scoops in 1/72nd scale to dress up the sides of the Revell 80' Elco kit's charthouse.

The White Ensign photo etched brass parts are just too flat...

Just ordered a binnacle, throttle, helm, cleats, and running lights in 1/20th for the Elco model I am now working on at the presence. Shapeways has been a god send for quality detailed parts and weapons specifically for PT's in various scales, from various designers.

SW sent me a promotion notice. You can save $10 (once) until April 15th 2016 by first registering at Shapeways, choose to "follow" my store, then use the code "mgpp4" at checkout.

This may be a unique code for me, if you are buying another's parts like Pat's ask them. I've been unable to find out much about this promotion... just make sure you follow the designer first.

I hear you guys, and I'd bet the smaller scales would sell well but it's so hard meeting SW's min thickness requirements without getting grossly out of scale.

Hi Jeff,

I wonder if perhaps some of the larger PT boat items might not be so grossly out of scale. One of Shapeways' designers is HOLDEN8702 who produces quite a range of nautical (and other) hardware in various scales.

My interest is 1/48, and he offers quite a selection in this scale, including a PT boat mast with the SO radar:

[url]https://www.shapeways.com/product/M7S7KVSS4/1-48-radar-mast-for-pt-boat?li=shop-results&optionId=57708392[/url]

He has just offered 80' ELCO mufflers in his lineup:

[url]https://www.shapeways.com/product/N87PGB4N6/1-48-pt-boat-mufflers-set?li=shop-results&optionId=59543088[/url]

These - and many other - items are also offered in many of the popular models scales by him, and his range is extensive.

I can see that English is not his first language, so I know I'm ordering from overseas somewhere, possibly France or Belgium. Having said that, I'd much prefer to order from our own local Jeff Davidson. [:-grin-:]

Cheers!

Parts of his mufflers look great. Others are bit odd to me. I wish he might have left off the lower mounting brackets as it is too thick for scale. Leave that up to the model builder to fabricate out of sheet copper or brass. The upper exhaust pipe and flapper also seem odd but hard to tell though with the posted drawings.

I would have recommended that the exhaust mufflers be 3D'ed in a few separate sections allowing for the various variations. The kit could include the major variations and allow the kit builder to use what is most suitable for their model. There are subtle differences in the upper exhaust pipes, collars, piping and linkages depending on which PT you are modeling. This is where the Dick Washichek blueprints become essential!

P.S. The (original) muffler bodies themselves were made of copper if I recall correctly.

Halol guys I am in the process of building the mufflers right now,and I spent some time figuring out how they were made.. From what can be seen on the digital prewiev it seems that the mufflers have features of different production runs all on the same item the rearmost flange/collar also looks odd.
Unfortunately the ELCO blueprints are a little foggy abuot the mufflers.
Anyway, hat off for offering such items as 3DPparts!!

Cool Bob, I'm happy to see someone is doing the smaller scales. And thank you for the faith in my work!

I'm looking forward to seeing those mufflers Daniele. You're right about the muffler changes, one other noticable difference is the reinforcing bands. Some go all the way around like on the 109 and some are short sections like HOLDEN8702's are. I have a photo somewhere showing both types on 1 boat, a guess would be one or some were replaced.

Yes Bridge, there's some off parts there. One noticable area is the flappers cocked at an angle, not sure why he did that. And I'd be partial to making them closed so that the required print thickness wouldn't show. Even better would be some of your PE for them, the brackets, and actuating levers. :D

Jeff,

As an FYI, it appears more 3D parts in 1/48 are coming our way for those with an interest in this scale.

The Shapeways designer HOLDEN8702 (Luis) lives in Spain and upon my enquiry has made 1/48 Oerlikon ammo lockers available in two sets; one with closed lids and one with open lids.

[url]http://shpws.me/M0y2[/url]

[url]http://shpws.me/M0y3[/url]

I've ordered one of each set and hope when they arrive they're up to your exacting standards.

Cheers!

For the engine hatch lockers, check out ELCO_Roll_5535-2_72SCAN_00530 & 529. They were rather simple wood boxes.

Luis HOLDEN8702 has also come through on numerous request that I have made off him. JFYI he has recently offered both Elco and Higgins exhaust in a variety of scales, very accurate scale figures in various scales and poses, and also a variety of weapons, both man and crew served.

Hi. This is Luis, writing from the sunny Spain.

Thanks for your kind comments about my models.

About the PT mufflers, all changes can be done to adapt them to your model.

It isn't difficult to change angle of flappers or size of reinforcing bands, even to delete mounting brackets. Only ask.

You can contact me here, by shapeways PM or even by my facebook HOLDEN8702.

Best regards

Luis

Welcome to the PT board Luis!

There is a section of the Elco muffler drawing that the owner of this board, Dick Washichek, kindly allowed me to post on this page that should help with the early mufflers: [url]http://www.pt103.com/Italeri_PT109_Kit.html#mufflers[/url]. Besides the flappers, note how the cooling jacket on the upper sides of the muffler bodies faired in to the inlets without sticking out.

Thanks, Jeff.

Yes, I've used this drawing for my design, but also some pics to make accurate the model.
Really I haven't any pic who exactly match this drawing.

But please upload an sketch about what you say, this isn't enough clear from your explanation.

Hi Jeff.

Yes, this is what I say, in this drawing you can watch some features that can't be seen in the real pics (sadly not too much photos available) or are different.

Anyway, I can do the model to exactly match this drawing. Tell me about your scale.

Best regards

I'm going to email Luis and request he make (2) running lights and (3) air scoops in 1/72nd scale for the charthouse of the Revell 1/72nd PT 109/PT 117/PT 167/PT 191 kit(s).

Luis, are you listening? [:-happy-:]

I think the arrows are pointing to the actuating levers Luis. You're right, images of mufflers are hard to find. Here's some I had of varying quality, hope they help:

PT 117:

PT 562, with the stepped hull they were experimenting with:

Unknown Elco 80, note the short stout outlet:

This one is interesting, it shows 2 types of mufflers on 1 boat:

Hi Jeff:

Great pics!

These let me clear that the drawing shows a real muffler.

Anyway, third pic you post shows the cover staggered from the tube, just like in the pics I've sent.

Then I think both types exist.

Bridge Carney did a lot of research on the mufflers when he was building PT157 model and writing his book "The PT-157: A Scale Model Builder's Notebook", Maybe he can contribute something.

The PT silencing muffler system was a very unique and essential feature given the nature of the 'Close Quarters' fight. It was how PTs evaded detection at such close ranges. Without it the growl of those Packard engines would have given their position away...and with dire consequences.

It was almost impossible task to recreate mufflers, linkages and salt water (piping) connectors for modeling purposes until the ELCO blueprints arrived on scene.

The silencing muffler system configuration seem to change throughout production for reasons likely lost in history (such as possibly making them better, or supplier variation or make them easier to maintain..I don't really know) so you have to research which specific PT boat number you interested in. Even in the photos posted earlier in this post it is not easy to see some of the details.

Check on which [Washichek collection] ELCO blueprints that would apply by looking at the title block on the right side of drawings (note: some drawings are in multiple sections). They typically list which PTs that drawing applies.

HELPFUL HINT: It is also necessary to get Jeff Davidson's Index to the Washeck blueprint collection if you want to save about a zillion hours of looking through the thousands of drawings

Jeff,
Those certainly would make a sylin' transom on the right size boat! The muffler and flapper collar/valves would look great as tribute to PTs. Just not sure what it connects to with that big flared intake :-)
