Thanks Tom,

The plate was full with other stuff, have some foundation problems with my house, but that will be taken care of during this year, before i can start with the house build it will take some time, so now it's back to building the Ko Hyoteki to relax.
The upside of the house story is, if all goes well the Cave will be extended by four time the room i have now (think big cellar), wonder if David will still name it as a Pig-pen, we will see in the future.

Manfred,
I gotta say, it is good to see you posting again.
Peace,

Thanks Bart,

Yup, especially when the stock of 6 mm aluminum rods is almost gone, since the lathe was spinning i also made the scope of the Ko Hyoteki, compared to the german scope it's simplicity all over,




Pretty much the same approach, first measurements and have a go with the lathe.



For now she's standing like this on the bench, scope ready and the antenna present, next hurdle is, making the resquebouy mechanism, i decided to work from the back to the front of the boat.
Still have to think about lifting the stuff, probably a KISS float system for both the scope as the antenna.

Order of operations 101, how you going to attack a part…….so important…..nice work Manfred.

Scope Up!!!, i'm back

Talking about scope up, made a sidetrack to do a other fellowbuilder a pleasure, he goofed around with building a Bronco Type XXIII, met him a couple of times to see if i could be of help, he made it lately to run his XXIII in the wild, and more important, after diving she resurfaced again, hats off to him.
He did have one request, wanted to have a scale scope instead of that blob of plastick on a stick, told him i could make this happen, took a scrappiece of aluminum and started turning,



Stage one, some stainless steel tube, and a scarppiece of aluminum, i did had to recreate the dimensions of my german scope, now archived for the future.



Coloured the aluminum with a sharpie and marked out the first dimensions.



Lower part has the right dimension for inside the stainless tube, working on the smallest part which contains the peroscopehead.



Turning the conical part of the scope, note that the smaller part not yet is to dimension, this gives you room to tweak with the angle of the conical part.



When the conical part is done you can turn down the smaller part under the head to dimension.



Finished product, ready for fitting it together.



As intended the scope slides into the tube with just enough clearance to add some glue.



To give a impression how big this part is, on my type VII those strange wires are also added, for some reason this was not added at the XXIII's scope.



Final check if i followed the right dimensions, after this i also added the scopesight and made a lens of epoxy for it, now this scope is his problem.

You will wonder what about the Ko Hyoteki?, well, between some other issue's i managed to do some stuff, first i solved the minute gap at the tailpiece,



This was my problem, due to the weight of the rearpart it sometimes wanted to separeate.



Drilled some 1 mm holes straight through the tubes, added some 1 mm copper false rivets.



Once pushed into their holes they secure the rearpart, when needed you can take them out.

to be continued.

Thanks Yannis, it was a pleasure meeting you and get a peek inside your cave, i hope everything is well now?

Manfred, I've got no words!!! You are amazing my friend. By the way, thanks for the photo !!!

Shaped the divingplanes and rudders, also attended one other item, it seems the hull is a bit off at the end, it should match the diameter of the prop, but it doesn't, solution was, making a piece to make up the space.
Laminated some circuitboard and did some work on the lathe, resulting in this.



A composition of all parts, yet again i raped David's designed prop for my own purpose.



First step is placing the transition ring, it is kept at it's place with one conical 2 mm screw.





By moving the prop backwards i created a problem with the endcap, it could not be secured anymore with the present grubscrew, carefully i drilled some holes through the rear prop and tapped M2 threads into the endcap, this had to be done right in one attemp, i only have one prop!!
By using conical screws they are flush and won't be a problem with turning of the prop.



Two parts together, not a trace to see how the endcap is secured to the rearprop, Phew!!!



The rest is pretty straight forward, first prop is secured by a grubscrew, second prop the same way, this contraption gives a nice transition from the hull to the prop, once painted it will be not that visible.

Now i'm playing around with another issue, since the rearpart becomes heavy it gives too much strain on the magnets, giving me a minute gap between the hull parts, it's not a big issue, but i want to have this solved before i start annoying myself on this.

Get'n there, Manfred. This is going to be a beaut!

Take one nibble at the time and she will see water in the future, in the past i allready made some preparations for making the rudders and divingplanes,



First i prepped some laminated stuff with the aid of a roll of flat lead.



Took the dremel and cutted the plates rough into their shape, i inserted a copper tube during the lamination process, those black specs are mini grubscrews M2, those will secure the stuff onto the copper rods.



Next step was, making the final dimensions for both the rudder and divingplanes, took measurements for the allready build rearpart to get it right.





All parts testfitted at their place, next step will be, giving the parts some profile and start thinking at how to couple the steeringrods, i have some idea's but first the profiling.

Getting closer each day, Manfred. This is going to be another stunner when you're done with it, my friend.

Picked up the pace at the cave, David has been stuffed with the V80, so i have my hands free, i had to make a new protector ring, cutted some copper strips and started fiddling.



Clamped down al rods before i could start soldering.





This was the easy part, it revealed to me i had a issue with the hull, you can see the gap between the prop and the hull, have to make a ring to get me a nice transition, this item will be noted down on the list.



The final coupler on the shaft to my gearbox, pretty much the same style as used on the type XXIII, did this on both ends of this hull piece, so i can still take it off.


Manfred.

[MFR1964]

Glad i could help you out with some new hull parts, can you give me your postadress by PM, otherwise it will take much too long to get the stuff inside your cave

Manfred

[He Who Shall Not Be Named]

Much appreciated, pal.

First thing I'll do is bond the two halves together, then cut the top of the hull away from the lower at the waterline. Then work out the indexing of the two halves, and set them aside while other work is attended to. Thank you, Manfred!
