Hi folks
Long time I have not been here 
But I had some jobs to do.

I did the same with my Tessar 400/4,5

Now it was not my lens so I had to be really carefull.
I made drawings of the blade:
And turned 46 as small as hamster's tail pins:

The longest was the waterjet - many orders before mine (2 weeks of waiting)
Blackening - one day
Pins and riveting - 8hours
Putting all ttogether - few hours - needed to find correct positions. Then I found the marks inside the barrel. And it was done,
