thank you, Bjorn and Robert for nice comments. Sorry for my late reaction but I had a long bussines trip.
I finnaly finished the adjustement holder. I used the brass plates in few lines. The worst procces was to desing of the prototype but it is too complicated with each next part too. I am satisfied with the result. Now I am finnishing new prototypes of eastketten tracks. I will see about the casting progress.
Have a nice day
