Elco 80' Mooring Bitts
http://www.ptboatforum.com/cgi-bin/MB2/netboardr.cgi?cid=101&fid=102&tid=4088
I made mooring bitts for 3D printing in 16th through 72nd scales and as part of it I researched the quantities / locations and thought I'd share them here. Deck plates of 1/8" thickness were used under the bulkhead 4 forward bitt and the PT 731-760 refueling at sea bitts amidships at bulkhead 21. A template for these is available here: [url]http://www.pt103.com/images/3D_parts/3DP_Elco_80_Mooring_Bitt_Deck_Plates.jpg[/url].
PT 103-108:
Quantity: 2. PT 103-108 used a towing bitt instead of a mooring bitt at bulkhead 4.
Locations, best guess from photos is at same position as PT 731-760 quarter / aftermost bitts:
2 centered on frame 69, 946 1/4" aft of forward point (about 19.9" forward of aftermost edge of boat including aft guard), 6 3/4" inboard of guard (outermost edge of boat) port and starboard. Horns to be parallel to boat side.
PT 109-196, 314-367, 372-383, 486-545, 546-563:
Quantity: 3 or 5. PT 522-545 had refueling at sea bitts (drawing not available) like PT 731-760 so they used quantity 5.
Locations:
1 centered on bulkhead 4, 76 1/4" aft of forward point on boat center line. Horns to be at right angles to boat center line.
2 (PT 522-545 only), best guess from photos is centered on frame 26, 370 1/2" aft of forward point, about 9" inboard of guard (outermost edge of boat) port and starboard. Horns to be parallel to boat side.
2 centered on bulkhead 61, 853 1/4" aft of forward point, 50" outboard of boat center line port and starboard (slightly outboard of outboard face of coaming). Horns to be parallel to boat center line.
PT 565-624:
Quantity: 5.
Locations unknown (drawing not available), best guess from images:
1 centered on bulkhead 4, 76 1/4" aft of forward point on boat center line. Horns to be at right angles to boat center line.
2 centered on frame 26, 370 1/2" aft of forward point, about 9" inboard of guard (outermost edge of boat) port and starboard. Horns to be parallel to boat side.
2 centered on frame 69, 946 1/4" aft of forward point (about 19.9" forward of aftermost edge of boat), 6 3/4" inboard of guard (outermost edge of boat) port and starboard. Horns to be parallel to boat side.
PT 731-760:
Quantity: 5.
Locations:
1 centered on bulkhead 4, 76 1/4" aft of forward point on boat center line. Horns to be at right angles to boat center line.
2 centered on bulkhead 21, 310 1/4" aft of forward point, 6 1/2" inboard of guard (outermost edge of boat) port and starboard. Horns to be parallel to boat side.
2 centered on frame 69, 946 1/4" aft of forward point (about 19.9" forward of aftermost edge of boat), 6 3/4" inboard of guard (outermost edge of boat) port and starboard. Horns to be parallel to boat side.
Some ref images, heavy on the boats that specific location drawings are not available for:
PT 103-108 had mooring / quarter bitts near the stern:

PT 109 on (except for 565-624 and 731-760) located the aft bitts farther forward and inboard:

PT 601 refueling at sea amidships bitt, fuzzy but good for figuring out location:

Jeff,
It's always a delight to view your CAD images, and even more delightful to use them as modeling references. I've read that we often have little idea of the impact we have on others unless they tell us, so here's Three Attaboys, Two Gold Stars, and a hearty Navy Well Done!
Cheers!

Why thank you Bob! It is very true what you say. I have a cardboard sign near my desk that says "Will Work For Appreciation". [:-lookhappy-:] I spent 2 days going through many drawings so the locations I had drawings for should be accurate. Those drawings are great but sometimes it's like straightening out a bowl of spaghetti. Good thing I love spaghetti and God Bless Dick Washichek!
If you have any interest or need, I'm also working on the running lights for Drew in 72nd and plan on 48th also. The lens won't be separate though, I barely got 35th to pass SW tests that way. But I have a feeling your kit already has good ones.

Hi Jeff,
The running lights in the BJ 1/48 kit are britannia pewter and are eminently useable. But any kit, no matter how good, can always be improved a bit, so I cut and filed out the metal lens portion of the light housings and cut transparent red and green craft beads to fit within the recesses. After the CA glue set, I filed and polished the lenses, scored them to appear as Fresnel lenses, then gave them a clear gloss coat. Took a while, but this is one of the satisfying things about throwing yourself into a model. I'm quite pleased with how they came out.
On another subject, I'm very interested in your 1/48 mooring bits from Shapeways. Looking through Dick's DVD deck arrangement & mooring bit prints, I come away with the idea that PT 187 had but three mooring bits. Am I correct on this?
Cheers!

I look forward to seeing those Bob! You guys amaze me with your modeling skills. I used to model but never reached anything like the levels you experts here reach. I was happy just getting the flash off.
Yes, 3. The one in front and the 2 P and S just aft and outboard of the coamings.
I need to add I'm sorry I can't credit the photos other than Ray Bean for PT 107, and the great closeup of PT 588 that Tracy White posted. Tracy does a lot of hard research into WW II USN subjects and generously shares it here: [url]http://www.researcheratlarge.com/[/url]. Ray has a Facebook page with almost daily postings of naval images new and old: [url]http://www.facebook.com/Eyes-of-the-Fleet-1491078084496345/[/url]. As usual most others were probably first posted by Frank, Ted, Will, Gene, or from the Navy image archive: [url]http://www.history.navy.mil/search.html/[/url].

Wow!! Another useful set of parts; will get it along with binnacles and throttle levers on my next SW order[:-happy2-:]
Who knows if we'll ever get deck hatches &frames[:-grin-:]?
Let's hope Jeff the Magnificent will have mercy on us poor scratchbuilders[:-good-:]

"Jeff the Magnificent"? You just made many people barf Daniele. [:-grin-:]
I planned on looking at the hatches soon but I think the hinge pins would be too small to make operational without breaking. Would separate parts with holes for a wire pin be OK? Or they could be made open as 1 piece.

Whatever.... having scale working hinges is excessivvely dangerous-unless they are made of metal- so I'll have them fixed: lazarette shut and the other two open. I think holes and wire pins would be the most detailed option; and that's where the[:-devil-:]is...

Personally I would like to see them as two parts so they could be assembled in any position from fully closed to fully open so you have variation.

That sounds like a viable option that would suit all potential buyers including myself. With all these quality parts now being available in 3D printing, it certainly make building a very high quality PT boat RC model a lot easier, and of much higher quality and authenticity. Thanks again Jeff.

I see a trend here, soon you will be able to buy a complete 3D printed model and download the software to print it yourself or go to Kinko's and have them print it. I think the plastic modelling industry is going to see a significant change in the near future, just as we see it now with movies and songs.
It's kind of exciting if you think about it, there are many people that have passion and talents to offer the model building community but not the resources to accomplish it in most cases.
One of my clients 3D prints aircraft parts in titanium. there doesn't seem to be any limit other than cost.

If anyone is interested, I have bitts, chocks, and cleats in 1:12 scale. I don't have a shapeways store, but we could work something out.

JEFF D Has recently released 3D printed Elco deck hatches in a variety of sizes including 1/20th, just in time for my build, thanks Jeff.

Anyone have any dead lights built we could use them in 1:24 scale.

Glad you like the parts Larry, I just got done making 26 more to cover the chart house vents. lol... 18 of them are placement jig sets that ended up being cheaper to make separate and print in the strong and flexible plastic in scales 35th and larger. They are all done from dimensions given in Elco drawings (except 1 vent on 565-624 boats) and are all different locations even though several in the different arrangements shown below look the same:

Frank, they'd have to be fairly thick for 3DP. Bridge needs to come out with his PE sets!

Just placed my latest order with Shapeways, now if one of the designers would make available early and late model Elco deck vents along with a bullnose and anchor locker my boat would be complete, thanks guy's.

Rumor Control (me) has it that Jeff might (one day) be designing...
1. Life rafts (Carley floats)
2. Cowl vents.
3. Late (large) engine room hatch.
4. Bullnose
5. Smoke generator with tie-down straps and nozzle with wand
Well, perhaps only in my (1/48) dreams.....sigh...
Cheers!

I've just received a Shapeways package with four sets of Jeff Davidson's parts in 1/48: mooring bits, deck hatches, charthouse vents, and, get this, Jeff custom-designed a throttle push rod deck housing for PT 187 for me.
How crazy is that? Immediate custom service! And to my discerning eye the parts are just (insert your favorite expletive here) absolutely gorgeous. Crisp, sharp, detailed, lovely......lovely....
As Bob & Doug McKenzie would say...."Beauty, eh?"
So, a tip 'o' the hat to Jeff! [:-cheers-:]
Cheers!

Same for my Jeff-designed 1/72nd-scale charthouse running lights and vents, and Luis's Mark VI depth charges and racks.
They're tiny, but they're perfect.
