You're probably right.  Makes perfect sense to me.

 The vendors at OSH had lots of workshops.  Would that be a source of instruction?  How about the local community college?Certainly, anything you can get will be helpful, particularly if it's free :-)   I looked into the typical class that you can get locally, and none of them really appealed to me.  They more or less have to teach you the history, basics, and techniques for every type of welding ever created.  I'm really only interested in TIG, and only as it relates to the typical jobs required for aircraft construction.  That's why the SportAir workshop was appealing.  It only covered 4130, and aluminum TIG welding.  Now that I've practiced a bit, with some success, I think I can probably get more for my $350 if I use it to buy argon, filler wire, and scrap metal to practice with. Rusty (can't wait to try cast aluminum)
