The ultimate machine

The Eckold Kraftformer was developed in the 1930s by Walter Eckold, who had been working for Junkers Flugzeugwerke AG (aircrafts).

Shrinking, stretching, doming, planishing and spot flatening are only a few of the jobs, that can be done with a Kraftformer. Maybe this acquisition will lead me back to the project.

Will show the tools in detail when working with them.

Seriously cool tool. Now that you have it you're going to have to start using it because it looks too doggone hard to move again.

Two choices.. set up home for a termite colony with a queen or set it on fire.
Tend to the "removal-by-fire" method, will place a set of extinguishers in pentagram form around it, that should prevent collateral damage and I do not even have to be present during "lowering".

Definitely! Getting it off the palette will be an issue.
Why take it off the pallet? Could act as a vibration isolator?

Buy some thin wood and panel in the side/end gaps and paint and it will look like it was always supposed to be like that :)

I'd love to see a video on the various things you can achieve with this tool. I't pretty amazing, especially when you realize that its all analog.

at least it has a lifting eye on top. or, maybe it's an eye for tying the building down in case of tornado...

Sunday´s highlight

Of course there was some idea of how to set the machine properly. Under the crossbeams of the roof there are quite solid supports for the transmission axles used in the 1920s. One of them was used to hang the 2.5 ton chain hoist which was acquired together with the Eckold. That hoist is even ten years older than the Eckold and that definitely is before steam-age. I love machinery of that time, it is mechanical, rock solid and easy to use.

It was a bit exiting still, but there ws not the slightest creaking or squeaking when lifting the machine. Not even dust falling down from the ceiling!

Adjustable machine feet have been ordered and for the time being it sits on wooden blocks.

First Kraftformer work

Some electrical and mechanical issues have been addressed, basically the brake of the push rod drive needed some curing, because it was blocked and caused the rcd fuse to jump. Interesting detail by the way, it is an electromagnetically operated drum brake sitting at the back of the gearmotor.

The shrinking jaws were mounted to shrink the tip ends of the driver side sill. They have a diameter of 60 mm, a bit too big I think, but that´s what came with the machine.

A video of the job is being prepared. Will have to learn a lot to create a plot but at least it´s moving pictures. Made some trials for my “video studio” as well.

LHD sill

The sill is almost finished, only the upper flange has to be made. When looking at it, you do not see how much thinking, trials and work were necessary to achieve this. Perhaps I have a small monomania about this panel!

See the video about shrinking with the Kraftformer here.




It was a two minutes job to do the rough work at one end of the panel. What I like about the Eckold is, that you do not need to use ear plugs. mine is fifty years old, a newer one is really silent, I suppose. After machine shrinking the corner and the edge have been sharpened by hammer and dolly.

In pic two there is the original (rhd), the prototype and the final part

Jack pockets

Second function of the Kraftformer, planishing. At the underside of the sills there are pockets to place the jack in, These are in production right now. Not spectacular, but good to demonstrate the planishing. Both parts of the planishing tool are rubber buffered, one of the reasons why it is comparatively quiet.

Passenger side rocker panel finished today. Not spectacular, but still . . .

A new inhabitant of the barn kept me from working on Lancias (and there was the Timossi and other issues). We collected the beast some 240 kms from home. It took us 3 1/2 hours of full throttle Autobahn. Top speed is 47 mls/h (75 km/h), feels like 350 km/h. But when you`re in crawl gear it will pull 30 tons and go everywhere.

It´s a pitty that it does not fit this forum. Unimogs are incredible machines.

Unimog!!!
Decades ago, I was working as a geologist on a metal discovery in the middle of Vancouver Island. Annual rainfall was 3500 mm, 137 inches (looked it up). During winter cold spells that included some heavy snowfalls.
We had a Unimog for getting around on the rough terrain.
Amazing machine--it had 8 speeds forward, and as I recall, the same in reverse.

Brian, mine has six shifters between the seats, two levers at the steering column and one below the cabin to be operated from outside. Maybe they have packed them all in one setup plus a lever for the ejector seat.

It is all very simple:nerd:

Main gear shifter (six gears, two of them to be used for reverse as well)
one lever for forward/reverse
one for the gear reducer (three levels: slow, very slow, super slow)
one to change between main gear and reducer
selector rear wheel drive, four wheel drive, diff locks
one selector for power take off front/rear/both including engaging/disengaging clutch via switch
outside under cabin: selection of power take off revolutions

the steering column levers operate the front hydraulics(lhd) and the back hydraulics(rhd), outside at the back there is a valve to select either rear hydraulic lifter (for attachments) or the telescopic cylinder of the dump bed

Any questions?:mellow:
