Converting the Bronco type XXIII to RC

[MFR1964]

Hello guys, it took me some time, but i'm back on the track, i had to deal first with some personal issue's.

Romel had send me a PM about the my early SAS, i think it's more usefull to answer this in public

Unfortunally i don't have pics from the system as build in the 80"s, it worked, that was all that counted, i must admit, we didn't used it as the way David uses it now.
For us it was more a safety feature, most boats where run on snort style, we placed a one way valve on our closed ballasttanks, the boat itself was slightly pressurised at the launch, when needed, you could use the overpressure, in combination with the one way valve to get your boat to the surface, the float on top of the boat allowed you to equalize the pressure.
David combined this into a much better way of use, so it can be used as often as you want.

Despite my setbacks i still managed to work on the type XXIII, first i had to finish the snorkelhead, an make a start with a new scope, working right now on the solution to get those things moving, pictures.



Started to build the details from styrene plate and placed the float on a working hinge.



Added some stainless steel tubing to get a more scale look, also placed the radar detection antenna and placed some aluminum mesh.



My completed snorkelhead, much more the same like the one on my pictures.



The inner float can be moved, i know i'm a detailnut, but making this piece working like the real one would be insane.



Last week i made a new scope on the lathe, right now i'm waiting for some stainless steel tubing to make things work, when i've got my ordered stuff i can start making the moving parts.

Manfred,
Why not make that snorkel head operational. You do need to find an alternative for that airsoft pellet as it's not bouyant ( had the idea in my head so i tried to see if it'll float).

Great stuff Manfred. Can't wait to see how it turns out.

Grinding away on the details, added a item inside the conningtower, and did some research on the snorkeldevice, as a bonus i'll show you guys what i'm building right now.



On the drawings and on some pictures there was a kind of step up visible, futher investication revealed this construction, used the part from Bronco as a mold for the UZO mount.



Making such a construction at that place creates a problem of trapping air, solved this by adding a floodhole just under the UZO mount, added this way it will stay out of sight when placed inside the conningtower.



Cutted away a part of the deck just under the step up construction, allowing the water to enter easely.





Finding pictures of the actual snorkeldevice itself was a bit difficult, most pics are too far away without details, dugged out my archive of books, and found these, combined with the drawings i made a start to rebuild the one from Bronco.





First step was, to make the one from Bronco hollow and adding the open space on top of the snorkel.



I have a complete collection of small hex bolts, used the 1 mm one's to add them onto the future flanges, still working on this.



Freshly made, i still have to remove the CA to get a clean look, the ball is a pellet from a airsoftgun, it's just the right size, have high hopes to let it move on my snorkelhead, did some testing, to be continued.

David,

Out of control?, sort off, i think, one of the problems with my way of vertical locking this boat is, i first have to make all details (weight), after that trimming will be done in one attempt, opening up those splitted hull parts time after time is not what i want.

Your XXIII is it hard to handle ?, or a easy driver ?, as for the CG i'll keep that in mind, thanks.

Manfred ... OUT OF CONTROL!!!!

Ran my boat today -- word of caution: you gotta get that things C.G. will forward of the hull mid-point.

David- Will having torpedoes in front help with moving that CG?

Thanks Murray,

All those evenings looking pictures and drawings searching details are paying off.

Sam,

For me it wasn't a option to leave the hatch as it was, it's a specific eyecatcher, adding some more details fixed that problem, making it functional was yet again a adventure.

LOL Tom,

You gave me a big grin on my face, merci beaucoup mon ami.

dat is fantastisch gebouw en verbazingwekkende details. dank je wel.
that is fantstic building and amazing details. Thank you.

[goshawk823]

The detail you're providing is awesome Manfred. I am particularly impressed with the life raft canister hatch. Great work!

Very nice work!!

Dan,

We Dutchies are used to live below the sea level, fighting against the sea is inside our DNA, so, we are always prepared to go under water.

And to cheer you guys up, some news from the Skunkworks, pimped up the dinghy hatch, conningtower hatch and made myself the horse shoe shaped resquebouy complete with the rigg attached to the peroscope protector, pictures



This is the endresult, compared to the Bronco one you've got more details.



The construction itself is based on the same construction as used at their ammo containers.



Since i have a slight disorder for moving hatches, this one can also be opened if you untighten the bolt at the front, and swing the brace aside.



Moving up to the conningtower hatch, the one provided by Bronco is a bit naked, so i added some items.



Added some handels and refurbished the hinges, made from thin solderingwire the new spring.



Due to my modifications it also can be opened.



To me this is one of the eyecatching items on a type XXIII, made the bouy from 3 mm plexiglass and soldered the holder from thin copper plate.



A dryfitt at the peroscope protector, the bouy itself can be removed when driving the boat, and placed back when the boat is at static display.

I still have to add some items inside the conningtower itself, so i can move up to the snorkeldevice, Bronco made a good base to refurbish it into the real thing, wait and see.

I made a hatch on my OTW type XXIII like David did to access the rudder post. I just rtv siliconed the hatch in place, and slid an exacto blade through the silicon when I needed to get to it.

Verrrry interesting...
