I was wondering what the best way of welding it would be.  I was
planning on tacking it all together, but for my first manifold it
might be better for me to weld it as I go so I can properly inspect
the inside of the welds to see if I should make any corrections to my
technique...   I'm worried about things moving with heat distortion,
but I guess anything can be corrected with some grinding and/or
additional welding if needed...

None of the books I have on welding give much insight to the actual
movements involved, so I've been checking out some YouTube videos of
people TIG'ing.  I've got a good grasp on the technical end of things
from the research and books I've read - now I need some hands-on
experience to *really* learn.  The videos definitely helped me
understand the interaction between the torch, puddle, and filler rod.
 Anyone know of a good instructional TIG welding video?

One question I have is when would 'pulsing' the pedal be necessary?  I
noticed some of the guys pulsing the pedal in some of the vids, but no
explanation why...

Sometimes I forget there are ladies present...  ;)   I guess the
problem is that 'shop talk' doesn't always translate well in print,
since nuance and subtlety rarely come through...

Although I don't consider myself a pig or anything, for the most part
I post on the list like I would talk with my car-guy friends when
hanging out at the shop.  Something I wish more of you bastages would
do to lighten shit up once in a while!  Admit it guys, when there is
no estrogen present conversation is usually peppered with some
additional "color".   I pretty much consider any female on the list as
'one of the guys' anyways...  Besides, my VW hobby/obsession is
supposed to help me get in touch with my 'inner hairy man'.  How the
hell am I supposed to grunt, swear, and scratch myself properly in a
politically correct environment?  :D

Thanks for the link btw!   Funny shit...

Later,

Mark.
