The hammering part at 1:40 might be doable as a repair attempt, but there's
no way you can spin the trumpet In a lathe. You'll note that all of the
lathe work was done when the pipe was still straight. It was the lathe work
that smoothed out the hammer marks.

Not to mention that it will need to be annealed first so that the metal
doesn't break. Definitely something that needs to go to a professional
to be repaired.

OP needs to 'fess up before further damage is done to the instrument.
