Hi Jim,
First, let me apologize for hustling off the phone yesterday. A
neighbor dropped by to visit and since he's a retired cop, I didn't
want him to leave so he could man the fire extinguisher while I
calibrated the torch according to your instructions. My tanks are
chained to the wall of my garage, so I had to do it inside.
I didn't
feel comfortable running the torch that hot indoors without a second
pair of eyes and hands around.
Second, I calibrated the torch to a Q-tip and afterwards the settings
read 6.5 pounds acetylene and 6.0 pounds oxygen with tank valves
open and torch valves closed.
(Does that sound okay? Running the 1.5 tip with a JOF flame, the
regulators read about 5.5 acetylene and 5.25 oxygen. Up to now,
I've run them both at 4 pounds for welding, regardless of the tip.)
Third, I still couldn't weld worth a damn afterwards. When one
of my filler rod ends balled up strangely on
me this morning, I
called my supplier to ask if I had the right rod. Turns out they
accidentally gave me a bunch of TIG rod a month or so ago. It was
mixed in with my oxy-acetylene filler and by sheer luck I kept pulling
out the right ones...until yesterday.
I just got home with the correct rod and think I'd better grind
the weld area down a bit before I have at it again. I have bad welds
in 4 different places along the seam.
I'm not a very happy camper, but I learned something.
I will let you know how things go. I should be confident, but I've
had so many setbacks the last couple days, I'm not going to make
any assumptions.
In the meantime, here are my other, comparatively successful projects,
in the order I did them. Most are under 10" in length, but
the tree and the last three are bigger.
Thank you again for your time and thoughtful support.
Best,
--Kira
