Machining a hydraulic block for heavy duty trailer brakes

My neigbor has a large trailer which has hydraulically operated brakes.
The brakes are not operated by brake fluid but are under hydraulic power which in turn is controlled by a valve operated by the brake fluid pressure.
It is a lot like brake booster but with steroids.
One part of this system is a block in which the hydraulic hoses attach to. This block has sone terminal damage to it and now a new one needs to be made.

In this video I use:
- Weiler Matador SV (1972) Lathe
- Schaublin SV-51 (1955) Milling machine
- Solberga (1975) Drill press
- Kemppi MasterTig MLS 2000 Welding machine
