Yesterday I continued with my Peripheral-inserts.
Because they are threaded into the housings there is imported to get the D-shape in the right angle to align with the pre-machined D-shape in the housings.
The D-shape closest to the housing are bigger than the round hole and the runners, so therefore I need to machine this with the inserts on the side.
I could have done a round hole in the center, and port the sleeves by hand. But I'm really not a "handyman"

And CNC-port are in my opinion the coolest.
It worked out pretty well! I was really nervous when I mounted the first insert...
I very satisfied.
Next is to deside how to couple the inserts with the runners, and also how my runners will look like, size and lenght. Butterfly-throttles or slides.
