Through Hulls

This is the last of the through hulls that I never got around to making.  It’s the through hull\handle extension for the main tank vents.  Made exactly as per the plans as the valves are the exact ones.  In the top picture, I am machining the 3mm O’ Ring groove.  I have the bar gripped with a thin brass shim to prevent damaging the shank I had just machined.

I also had to run the machine in reverse and cut from the other side as this is an internal grooving tool and I don’t have any others.

Still have the threads and flats to do, but its almost there.
