The ends of the boiler are welded much better than the pressure tap.
Boilers are dangerous, you might want to cut it out and try again with a
larger insert. Try mastering gas welding or cranking up the amps on your
mig.
Could probably use a counterbalance.
It's not fancy, but nice work for a beginner.
