Since, whatever size props I get they will still have to be trimmed to represent the actual ones, because I am using tug boat or utility props. The pitch is about the same but the bite overlaps when installed in line. I used a photo of the ha 18 an held the corrisponding prop in front and used a marker to draw the contour outline and shaded in the metal to be removed. Then masking tape to transfer to an aluminium template to mark the other blades uniformly. Same procedure using the reverse side of the template to mark the counter prop.basiclly some of the blade face has to be removed from tip to root. and about mm of tip to conform to the clearance of the cage. Ill end up with an 80mm prop from the 90.Ballancing the final trim is not so dificult they are low rpm to start with and not as tempromental as race props which I have some experience with in, full scale boats. They are going to have some beafy shafts but I will fill the OEM 5mm threaded shaft holes and re drill new sized holes individually. Just picked up a big Chicago drill press, so now I can play around with stuff like that better with more precission. Dont know where I will set it up yet, but I will find the room.

Havent been paying much attention to this project for a week or so. Some more props came in the mail that I had ordered awhile ago. Before I had even setteled on the scale. I just made a quick guess for the 1/24th and ordered a set of Raboesch 25mm 4 blade counter rotation from Westbourne models in GB. Shortly after I ordered a pair of 90mm Rivabo for the 1/16th scale. They both are beautiful, but I cant use them. I just re ordered some 75mm, that I will use on the 1/19th scale that it turned out to be.

George. There are no plans, so to speek. The drawings, are just drawings with a 1 foot scale line below. If you want a particular scale, you have to do the math and have the picture enlarged to suit your application. I used this and blew it up with all the original notes included as a plan sheet. As for actual detatils you have to interpilate from your photo searching. My self, have been researching this particular boat H-19 since 1962, and theres still stuff I'm learning about it.

Hello Again

Thank You for that. What do I need to do to get either a 1/16 OR 1/24 scale copy of the plans from you?

Hello HNSBN

Just wanted to see if you had a chance to send me the Type A plans, I PM you my address as per your instructions. Question, what scale are they in and what enlargement factor is needed for 1/16 Or 1/24?

Thanks Again for the posts and lectures HNSBN.

George

I've been busy in the shop. I'll go to the copy place in a day or two.

I was looking around at various commercally made model props I found these made for a Kurtz, but, they could be stacked 90mm fwd 80mm aft, bore the shaft hole in the fwd to accept the RH drive shaft tube and the inner shaft LH. The blades need some tip trimming to resemble the original's tip shape. Just a theory, dont want to buy a $100s worth of props to experiment on a whim.

Using it as a door stop.

LOL. You SOB.

Stuff I send out is on my dime -- I don't take payment outside of Caswell. So, when I send stuff out it is free and a favor from me to you. And I fully expect you to DO SOMETHING WITH IT! Aint' that right, Romel?

Hello

Oh Master HNSBN

Would you grace me with a few things:

1. Copy of Gene`s Type A submarine build plans?
2. Instructions of how to build his counter rotating propellers gear box? Is Gene`s and Adam` props. the same size?
3. The chance to buy from you a set of those metal propellers?

Also you said you had email Adam reg. his build, what has happened with that conversation? IS he going to sell a copy of his hull?

Please let me know and PM with price and payment information.

Thank you for Your Indulgence.

George

I don't PM. Conduct business here (However, 'sensitive' stuff like mailing address, you can e-mail to me).

You're in luck, I'm slumming today -- I'll talk to you mere mortals today as though you are my equal:

1. E-mail me your mailing address and I'll fix you up -- IF you promise to do something with them!!!! dmeriman@aol.com

2. Gene's and Adam's models are different sizes. Adam's is 1/16. Gene's is 1/32. Let's hope Gene is following this thread and will give you the answer you're looking for

3. I've only gotten to the master stage on the 1/16 propellers, no tooling from which to cast production parts. Anyway, I don't sell anything outside of the Caswell catalog. All commercial work is handled by Caswell.

Talked with Adam about Merriman-Caswell going commercial with his 1/16 Type-A. He's agreeable to the idea, but we have not come to terms yet. Also, once we get to an agreement (IF we get to an agreement), it will be years before I can get a kit ready for market.

Stuff I send out is on my dime -- I don't take payment outside of Caswell. So, when I send stuff out it is free and a favor from me to you. And I fully expect you to DO SOMETHING WITH IT! Aint' that right, Romel?

I now ascend back to my throne, atop Mt. Olympus (crack of thunder) where I continue to watch over you little-people, as I issue the occasional snort of contempt.

Oh! Oh! Dave the sleeping dog just woke up. I should have never stepped on his tail. If you ever do decide to run off a couple castings, of course I would be more than happy to compinsate you with yankey dollars. Hmmmm, building plans?.... oh!, would they come with the KIT? do you have any RTRs in the shed?? painted? with the little flag and the poop on the tower?( just kiddin) OK zero dark 45, got to get serious today, There putting sewers in down here in the middle keys, finally. Stacks and stacks of pritty blue PVC all diameters. Lots of short pieces left over.

Manfred, there are several fotos of the I-18tou at the Naval Acadamy at Eta jima in Japan. The electric dynamo is very impressiveone thing I have noticed is that several pictures of that type of propulsion on the migets have the forward prop a greater circumfrance than the aft
