Building the winches for the lines that control the tiller I needed a ratchet wheels. First I made a prototype in plywood. Then Miki made a one on the computer.
Lena and Mikael boating people here in of Svetsmekano i Västervik helped me to cut out one to test on their fantastic abrasive water jet of 10 mm stainless steel. That was no problem they can cut out any figure in up to 200 mm stainless steel and most other materials as well to a tenth of a millimeter.
The photo below shows lena with the machine.
Below is the product and the plywood prototype.
Now when I got the pieces I will continue trying to get a good solution.
To bee continued…
