I machined a part out of metal for a bud today that I'm rather proud

It is for this thread. Whatcha make?

Fitting for a bud's pressure washer. The aluminum casting was cracked
at a hole threaded 3/8 NPT. Welded the casting but didn't get clear
down to the threads, didn't want to barf them up. Skinned the nose
flat in the mill, made an NPT fitting with a flange that meets the
nose blackout tight just about the time the tapered threads snug up.
The challenge was getting the taper and lathe-cut threads so that
would happen. A little Permatex between flange and casting nose,
and voiley! I made the flange so it could be welded to the casting
and picked up some 4043 TIG rod yesterday, but I think Permatex and
torque will seal it just as well.
