Hubert, I´ll forward you a telephone number from a classic car guy located in Wülfrath.
He´s running a Schenck, too. Take some hours of time to visit him, you´ll be fascinated !

It´s analog, but it doesn´t tell you lies. It´s a great thing !

PM sent !

no hurry hubert, just curiosity more than anything. but now it seems you may have a local expert to visit?

I talked to the classic car guy with the Schenck today. Very friendly and accomodating man. He is member of alfabb too, but somewhere in one of the "Alfa-corners" He will come over to give some advice on how to put the brake into operation. He surprised me a little bit by telling me he´d use a 3600 liter tank (950 gallons?) as cooling water supply connected to another tank of 1000 liter (260 gallons?) installed four meters high in order to achieve the required pressure of 0,4 bar for the brake, furthermore a solid base would be mandatory.

He also said these would be fantastic for terminating engines by faulty operation.

That sounds promising and a bit of an adventure. I am not scared at all , had the drawings made for the adopter flanges instead!

Will see what really is necessary to operate it from time to time. BTW this seems to be an approach for another small business "analog laboratory work on analog engines".

Again a small project dropped in in form of a 1950s chain hoist with a planetary gear, made by a company some 15 miles from my home. Brand name: "Planeta", nomen est omen. This has to be explored and restored in between. No big thing.

You'll very much enjoy all those details. He's a passionate vintage & classic car racer, too.

Her time will return . . .

after the Flavia engine of my buddy Thomas is done and installed and the Flaminia engine of my buddy Christian is done and installed and the snow plough of the MOG is put back together and the gantry crane is erected in the barn. Did i miss anything? A yes, my wife and daughter. And there was something . . . how was it called? Job, I think was the word.

I’m not suggesting you ignore the Flaminia but your off topic is every bit as interesting, keep it up.

Chain hoist

Blast cleaned the parts where applicable, degreased and mechanically cleaned the rest. Painted the components (not happy with the color, should have taken the darker blue for it), greased the bearings and the teeth, put it all together, except the load chain, which I forgot in the company.

The design is simple and bullet proof. The planetary gear has a ratio of 1:8,3. Added the ratio of the diameter difference between drag wheel and load wheel, which I forgot to measure but estimate with 1:2, we have a total of 1:16. Even weak people like me can pull 500kg easily with it.

The hold and release mechanism is really simple, there is the ratchet making such a confidence inspiring clicking sound and the clutch pads (one of them, the brown disk, to be seen in one of the pics) attach and release so defined. It is gorgeous for an almost seventy years old device.

It radiates much more confidence than an Asian item nominating five times the load.











And this is Tommy´s Flavia, which actually is my first restoration and my wedding coach. BTW, the camera is ok, but the clouds hang low.

First time I've seen the inside workings of a differential pulley.
Great picture of the Lancia in the fog.

Main light relays

The main lights are actuated through a single relaybox. Inside there are three relays, one of them operating as a toggle switch for changing from low to high beam. Interesting layout, as the toggling is achieved mechanically using a finger that hits a kind of ratchet. This mechanism is not very reliable nowadays. Hence time for something new. Frequently the solenoids break and quite often some of the riveted contacts fail as well.

Some time ago I built a small machine for rewinding the solenoids. It was equipped with a counter for making the exact number of winds.
This is very labor intensive and the winding machine got lost somewhere.

The first idea was to replace the toggle relay by something fitting in the original box to keep the original look. After the prototype of the electronic toggle switch was finished on a small board, I thought it might be a good thing to replace the other two relays as well.

A suitable circuit board was cut and some preparations made to make it fit inside the box. The free space on the left will take up the components for the toggle switch.





The relay on the right has a new coil.



worn components



toggle prototype





Needs completion

Excellent work as usual, Hubert, but this time I admit mixed feelings.

I've struggled with a similar issue on Aurelias. The voltage regulator is delicate, if I can put it that way. Several electronic conversions have been made over the years, with varying results (some have had overheating issues, and burned up the generator in the process). At this point I am (gingerly) running an original unit, but am always hoping for an improved one in an original case.

But I have always been particularly enamored of this little electro-mechanical device (though I confess that having had no issues myself, perhaps my reluctance is not justified). I've opened these up just to show others, even long time Lancisti who were unaware of this near anachronism. It just seems a shame to lose it, but reliability and safety do come first.

I am absolutely with you regarding the electro-mechanical devices and I keep them as long as possible, just because I love mechanical things and the fact, that you can repair them (to a certain extend).

The reason for the ongoing conversion is that this particular one is beyond restoration. It passed a serious "melt down". the springs got blue, the coil bodies burnt and deformed. Furthermore there are some originals left (including a brand new one), two of them I restored as decribed above. But when you do not use them frequently, they start getting unreliable basically failing during the biennial technical inspection

Besides this there were several inquiries of Flaminia and Flavia owners about how to fix these. This is my attempt to do so.

interesting. in the industrial control systems i build, we sometimes use mechanical ratcheting relays. i find them quite reliable actually. mind you, these are typically sealed so don't get much contamination, but they can solve problems if i don't have the right software to get into someone else's control system, or if i just need a simple holding output from a single input.
what would be the current carrying capacity of the relays you have installed on the breadboard?

Brian,

the main issue is that the actuating arm does not come back and therefore blocks the operation. Another thing is that the four toothed sprocket sits on a shaft that has a square area. This is pressed by a pair of leaf springs. I suppose that the intention is to let the shaft turn 90 degrees on every hit by the actuator. It happens that the shaft sticks in an uncomplete move and the relay stops working. It may get loose again, if you keep on pushing the high beam button on and on, but that is what I mean by not reliable. (Sorry for my poor explanation, the mechanism is quite complicated and i am missing the correct vocabulary, best would be to shoot some macro pics and show, or a video maybe?)

The relays are good for 16A 250VAC.

Hubert
