While there may be CODE issues, it is pretty SAFE to install a 
new, proper 240V outlet wired with the hot wire from the "A" side 
of the panel going to one hot blade of the outlet and the hot wire 
from the "B" side of the panel going to the other blade. The 
ground pin MUST be the ground wire, NOT the neutral. To be SAFE, 
the "hot" wires MUST follow the same path as the associated safety 
ground (green) wire all the way between the panel and the outlet. 

Another recommendation. I would take the advice that others have 
offered to ignore some of your parents' direction regarding not 
modifying things with the guideline that you 1) do it SAFELY and 
2) if you do it SAFELY, what they don't know won't hurt them. And 
buying and installing a new panel is a VERY good idea. 

I wrote the tutorial below for people working in pro audio, but it 
applies to home wiring too. It may help you understand and think 
about your problem. I've started a version of this for hams, but 
not had time to finish it.

Now, there's another problem you may not have thought about, but 
you should. When you fire up that Titan, you're going to find the 
RFI susceptibility lurking in all kinds of stuff in your (their) 
home. Radios, telephones, home entertainment systems, etc. That's 
likely to be a far greater problem than the 240V outlet. It was 
for me in Chicago when I did the same thing several years ago in 
the 110-year old house I owned. When you get to that stage, check
