Bronco Type XXIII in 1/35th scale

[Warpatroller]

Just to steer things back on topic for a moment (sorry).

I've been working to develop the jigs, holding and assembly fixtures, and process required for efficient production work of fittings kits and SD's. Samples of that work below:

Look at all those pretty propellers!

I haven't forgotten about the Simon Smith tube door schematic scans.. I have had a heavy disruption of my life occur last week, so I've had more pressing matters to attend to. My scanner is hooked up to an old XP tower that I no longer use much and currently has no monitor attached to it. I will eventually scan them and post them..

I agree! Except the training stripe and boot line need to go. And the entire boat should have a rusty appearance from lying submerged for 68 years. I also think the boat is too small in size when compared to the beach and palm tree in the foreground. The real thing was triple the length of a Seehund midget sub. The composite makes it look only about twice the length of a Seehund at best.

Remember the book, and movie, A Twist Of Sand? posters and book jackets had some rather striking images of a Nazi U-boat (experimental, suggested to be HTP or nuclear powered) sail, rusted and pitted, sticking out of the surf. Something like that me thinks.

Some recent work getting the prototype Bronco 1/35 Type-23 kit completed. Also some rough shots of the -- soon to be commercially available -- fittings kit.

We have our first public r/c boat run on the 18th and I want this bad-boy to be ready for our show at Nauticus. Gotta make the Koi pond there safe for National Socialism!

I am not familiar with that book or movie, so I looked it up. I found the cover image you're referring to. Yes, that is kind of what I had in mind.. I don't know what kind of tower that is supposed to be on the book. It has sail planes on it. Maybe a secret Walter/Nuke prototype.. I'll have to try to check out the movie sometime..

David, you never cease to crack me up! I can't even begin to count the times I have laughed out loud at things you have posted, here and else where, over the years.

When you get the Bronco Prototype functional, please take some photos of it in the water. The 18th is only 9 days away.. Should be the first operational Bronco XXIII on the planet! I am certain Dönitz, as he peers into your cave from Valhalla, is liking and proud of your work! His dream for an operational fleet of XXIII boats may finally be a reality 68 years later..

You need to have a commissioning ceremony for it, as it is added to the register of the D&Emarine! This event is worthy of video recording too! Exciting times in Virginia Beach these days!! Wunderbar!!

Yes, video tape this sub in the water! I'll take care of the editing, if you need, just get some raw footage. Oh, I forgot, please.

[He Who Shall Not Be Named]

I'll still and video document the eventual model, guys, don't fear.

If I have the boat ready for next week it will only be in the basic colors -- no time between now and then to weather the thing, that will have to come later.

Yeah, I have my ... moments.

Thanks for the offer, Tom. I might take you up on that.

ah,well. our son graduates from college Saturday, otherwise I would have driven down to see it in person.

First things first, Sam. We'll be doing Nauticus all summer long. Get a boat ready.

Some of yesterday's work. Hope to get base colors down tonight.

[goshawk823]

That's a great looking boat, David.
I remember your advice from when I built my OTW model, and the scum line/waterline colors depicting cold water operations. "Cold water colors" for that detail...lots of grays/browns... with the dishing detail you're doing on the panels, it should look awesome once it's done.

Will the propeller set screw remain raised some above the hub surface like seen in your first photo? Or has it just not been screwed all the way down. I would think it should sit almost flush with the surface of the hub.

Looks like you have chosen to mount the schnorkel, fixed, in the lowered position. I'd like to have mine raised, so I can use the schnorkel shaft to visually track the boat in my lakes out here (with their somewhat poor water visibility), while it is running submerged.

I gotta find a 4-40 X 3/32" long set-screw source! 1/8" is too short, and 1/4" is too long. Damn!

Your call on the snorkel.

You say you need 4-40 x 3/32". I have seen 4-40 x 1/8" set screws online, $5.37 for 100 screws, at the supplier in Texas below. They don't have 3/32" in 4-40, at least not listed on their site.

1/3" is too short, and 1/4" is too long? That makes no sense.. Must be a typing mistake..

Why use a set screw at all on the prop? Why not a threaded prop shaft and threaded propeller, like my 32P kit came with? You are already having to tap the side of the hub, for the set screw, why not tap the shaft end of the hub instead?

I am assuming doing that might make your manufacturing process for the propellers more difficult.. You must have had a reason for going with a set screw.

I have no experience with set screws on sub propellers, but I do find them annoying on my RC tank.

My Tamiya 1/16 Tiger tank, has axle drive shafts that are secured to the gearbox output shafts via set screws. I have found that after running the tank for a while, the set screws ALWAYS loosen and start backing off, causing the axle shafts to wobble a bit. They are not easily accessible without partially disassembling the tank. Actually, as I recall, I have to remove the gearboxes from the hull entirely, to crank them back down. Some guys put glue or thread lock on the set screws. I guess that is the only way to keep the damn things in place. Then maybe they become set in place permanently, which would be a problem for maintenance if you ever want to remove them. Maybe I should quit *****ing about it and just put thread lock on them..

By the way, in general, those Tamiya tanks are like babies and need constant attention.. At least I've found the Tiger to be that way. Apparently the real Tigers were not much different in that regard.

Yes, I meant 1/8". Good catch, Steve.

I use the set-screw on the propeller as I use a Dumas style universal coupler on the forward end of the propeller shaft. I have to first run the shaft through the stern tube from the inside with the coupler already made up. Could not do that if I screwed the propeller down first.

I've played with different propeller-coupler-shaft arrangements. This current one suits me and my machiness.

Started painting the Beast today -- stay tuned for pictures later.

If you meant 1/8" is too short, 1/4" is too long, then wouldn't you need 3/16", not 3/32" length set screws? If so, the supplier I linked to does indeed carry 4-40 3/16" set screws. I am not trying to be a PIA, just attempting to help.

[He Who Shall Not Be Named]

And helpful you have been. I'll check into that supplier. 3/16" would do the trick. Thank you.
