Give me 5 bucks for every time you did, as i want to stop working.

(what have I done??)

[MFR1964]

Did some work on the Ko Hyoteki and found out why i had to swim, going forward no problem, reverse jammed the props, re-adjusted the space between the props to get me some space, that seems to be the solution, now everything runs smooth.
As for the steering, the magnets came loose from their fittings, glued all fittings on both the SD and on the boat itself, next weekend i hope to make some test-trails to see if the steering and propulsion is solved, due to the size of the rudders i suspect she will turn as a pig, if so, i want to enlarge the lower rudder and keep the upper scale.

Did a test this weekend, and yes, she steers like a pig, so i have to make the lower rudder larger, still have some issue's with the drive train, sometimes it runs well other times i have to row it by myself, i do have a other solution, but i first want to try to tinker the gearbox.
The SD was dry inside, only one drop from the SAS inlet into the SD, want to place a watercatcher to solve this issue, pretty much the same way as i did with SD from the type XXIII.

What?.... no pictures???!!!! (I lay up your Type-21 hull this weekend -- found I had some slack-time Sunday).

[MFR1964]

I guess nobody has the guts to tell you that you are a impatient guy, be patient!!, pictures will follow when i start cutting away on the rudder, first i have a type 17 to balance and do some testing with her.
And make some room for that giant type XXI, thanks for the effort.

Manfred.

A man has lost all size perspective when he describes a 1/96 scale Type-21 as, 'giant'.

What's wrong with you?

Most of us are comfortable in the Newtonian universe where we don't get bogged down on ultra small things. But NO! Not you, Manfred: you're more at home in the micro-worlds of Bohr and Heisenberg. What are you, some kind of watch-maker??

[MFR1964]

These times i use magnifiers, so everything looks big, i bet you now want to scrub your brains

You do amazing work.

Despite the fact i didn't trim the Type 17 because of bad weather i made a attemp at enlarging the lower rudder of the Ko Hyoteki, pictures



Step one in the process, have to get the cone part seperated from the rest.



This piece is held at his place with two small pins, once removed you can separate the parts as on the picture.



Made some lines for the piece i wanted to cut.



First pass with the cuttingwheel of the dremel.



Used a baby-saw to get the piece cutted free, wanted to re-use the cutted piece for enlarging the rudder,



Made on both pieces cuts with the cuttingdisk, this was done to get me a small strip of copper between the parts to give some more strength.



Initially i used superglue and bakingsoda the get me the position right of both parts.



For now i'm at this stage, glued the parts with epoxy glue, this has to set first, i'll leave both parts in the rough, first want to test if this helps, if not i will repeat the same at the top rudder.

I has been some time, but due to the good weather i decided to slap some paint on the boat.


First step, remove all things which i don't want to spray in the colour of the boat


Splitted the boat in four part, hanging from wires in the garden.


First run of paint, in the end i gave her three layers, better thin in the beginning, adding paint is allways possible.


When the paint dried and hardened i build her together from all loose components.


Made the propellors looking brass, stil have to weather them down.


Conningtowerl is build up, inside of the hatch has become white.


And finally the business endt to the submarine, gave the torpedo-dummy's the same colour as the hull, those can be removed to be replaced by some live torpedo's

This boat is still resisting me to work properly, last meeting in Germany i had to swim AGAIN!!!! to get her on the shore, after that i putted her aside on the shelve, lately came up with some new idea's and placed her on the bench.
As for steering, pretty much the same story, enlarged the lower rudder to no result, best option is to go for the rudders used in the type B variant.



First i decided to get me a new drive-line, those are the parts i've made.



A better view how things work, those gears driven by the inner shaft are used to get the top O-ring spinning, which will turn the outer shaft.



Closed up the contraption for testing, if i remember right it was Romel who gave this idea about this configuration for spinning both props.



Did some rigirous testing with the upper drive-line, it works, but too much friction when using the standard E motor of the SD.
The new lower drive-line is made with some pinion-gears and a Carbon shaft, pretty much the same i did with the old drive-line in the past, this time made it more sloppy to avoid waterhammering, testing revealed a smooth run in both directions.



Since the drive-line is running smooth i turned my attention to the steering problem, first step will be altering the cage to a model B type, so i can use the enlarged rudders present on this model, for now it's dry fitted with some clamps, ready to be soldered, to be continued

Is the inner shaft running in bearings/bushings or up against the full length of the outer shaft/tube?

[MFR1964]

The innershaft is running in copper bushings, used a carbon shaft for the innerpart to get lesser friction.

More progress on the rearpart, and a grazy idea to convert the boat, pictures


Everthing is soldered, still have to add some details, but the base is there.


Made the new rudders from 5 mm plexiglas, those are 4 times bigger as the old ones, hope that will to the trick.


And now my grazy idea, since i alter the rearpart as on the type B, why don't rebuild the boat as a type B?, made some drawings to see how it will look.


Trying the drawing on the tower, i think it's badass, some strange netcutter on the tower.


Since the decision was made, placed some clear Vivak on top of the drawings, this way i preserve the drawings for a next time.


First step in getting the netcutter, bended some copper into the right shape and made a dry-fitt on the drawing.


Those parts have a U shape, by using the vice, hammer and some wood i managed to get the shape right.



The top netcutter ready to be soldered.


Yet again a dry-fitt before i solder those parts together, tomorrow i will turn my attention to that curved part of the netcutter, to be continued.
