Barry and Dennis,
OK, I found 2 sets of fuel tank sketches/plans in the Brodhead Piet Assoc.
newsletters; Jan 2001 and July 2001. They are rather different designs, so
you can pick whatever suits you. One specifies 6061 alum. & the other terne
plate, but you could probably make either one out of whatever material you
want. I'll be glad to send you copies of both - send me addresses.
Cheers!

I'm incredibly frustrated........just finished trying to do some welding and
it just doesn't seem to be going well. Took a lot longer that the
"recommended" 10 seconds to make a puddle and for some reason I got a lot
more sparks than usual several times....and I'm afraid I may be burning all
the carbon our of the metal and leaving it brittle....
I'm going to call my tech counselor and find someone local that knows what
they're doing to give me some instructions/critiques. But in the
meantime......can some of you welders (I KNOW you're out there, I've seen
some of your welding!) give me a hand? Maybe look at some pictures of what
I've done and see if you can make some suggestions? I know it's not hard but
I have no idea whether I need more practice or a modified technique
(training)...
I'm preheating the general area of the parts to be welded and I'm using a
"forehand" method. Material thickness is .090, using oxy/gas and 3/32"
E70S-2 rod, Victor '0' tip. The flame is tweaked down to where the feather
just dissapears and there is a relatively quiet roaring sound......
I've posted 5 "pre-sandblast" pictures on my mykitplane.com build log:
http://www.mykitplane.com/TaxiWay/TheHangar/PlaneManager/buildLog.cfm?BuildL
ogID=341&PlaneID=52&Menu=BuildLog
I can add the pics of the sandblasted parts if that helps.....
I simply don't know how close to acceptable (or how far away) I'm getting
with this....... If you can help, a private reply might be appropriate but
replying to the list is fine with me.
Thanks,
a VERY frustrated Piet builder in Plano........

Jim,
I'm self taught, with my AP Mentor looking over my shoulder from time to
time, BUT, the hardest thing for me to get used to was the time that it
takes the work to get to puddle temp. .090" is pretty thick and should take
more than the count of ten to puddle. I've never heard that term of 10 sec,
but maybe for something .032" or less. Don't think the time is a factor.
On most of my Piet. I used a 000 tip. Once in a while used a 0 tip , and on
the .090" had to go to a 1 tip. What tip size are you using? If you are
joining a group of .090" matl. Don't think that a 0 tip will ever get you
there. What type rod is that? My mentor advised using mild rod only.
Just another welding tip to remember,,,always point the flame, like an arrow
other depending on matl thickness, mass, etc. You can also "shield" the
thinner matl with the rod, not to burn it up.
Practice, practice, practice.
Took me years to get to a point where they're not necessarily pretty, but I
trust them.
Letting the joint cool in STILL air is VERY important for 4130. Or it'll
shatter like glass

hmmm, hey, few things I haven't tried!......increase the tip, get some mild
rod (is that the same as R45 maybe?) and keep practicing (well, I've done a
LOT of practicing!).
I've started a list....this is a nice start.
Thanks very much Walt.

What tip size are you using? if the tip size is too small, you can heat it
all day and it won't puddle.
Also if you want to practice today, use coat hanger for practicing. It's
basically the same soft drawn wire as the welding rod. Just doesn't have
the copper coating to stop rusting. Just kind of preburn the varnish off
as you go.

I have never heard of 10 sec to puddle. What pressure are you setting your
gas and oxy.
Popping can be caused by getting your tip too close to you and/or having the
flow of the gasses set to low.
If you are worried about burning the carbon out of the base metal use a
carborizing flame.
Keep practicing.

Coat hanger wire is not the same. Coat hanger wire can be of any alloy and
unless you get you coat hangers from the same lot they probably are not even
the same. Now for practice and automobile exhaust systems coat hangers are
ok but for anything else use a rod that you know is correct.

I just said " if you want to PRACTICE today, use coathanger. You won't know
the difference, if there is a difference.
Would I want my engine mount done in coathanger?,,,no,,,but practice with
it.

I've never figured out why links get trashed when you copy them to the
list!!
Oh well, maybe it's best just to go to www.mykitplane.com and look at
builder's logs and look at today's entry in my log....
Jim in Plano....not QUITE so frustrated now......

Jim. I found that practicing with .065 or .043 (?) was helpful. .090 and
.125 were more difficult
at first for me. - Icould never feel when he metal was "ready" - I'd get
impatient and start jockeying the flame and sticking the rod in before it
was ready. Also I found that starting with a simple fitting or just just
simply combining two parts with and edge weld made it easier because of the
uniformity of the fitting - you don't have to deal with the heat sink nature
of certain parts of complicated fittings.
2 cents
good luck. Keep practicing..bert

Jim,, I don't know about counting to 10 for a puddle, but I might suggest
trying a #2 tip, bring your flame down to about half an inch. Make small
circles slowly until the puddle starts,, then hold straight and start
feeding with the rod. The #2 tip has a wide range of adjustment so you can
increase or decrease the flame. If she's popping,, pull the tip back a bit
and make sure you use the tip cleaner after that happens. hope this helps.
Carl

Jim,
I have a really good book that I bought at Hastings The Welders Handbook by
Finch/Monroe. Now first I must tell you there are a few lines you have to
read through. For one he talks about your shop temperature, lighting,
breezes, coper coated wire ect. Made me think that a person would need a
semiconductor clean room with perfect atmosphere. But I know dammed well
most Pipers, Aeroncas, and Taylorcrafts were not built to his standards, but
the guy is a certified welder.
Some excellent things he points out are different tip sizes for different
thickness material, operating pressures of your regulators, carbonizing flame
(good) vs. lean (Bad) pulls the carbon right out of the material, overheating
the tip which causes popping. Now I could go on but typing is not my cup of
tea. If by chance you don't have a book, try and get one.
I looked at your parts, first I hate to see people practice on finished
pieces. Try setting up some scrap without doing all the finish work and
welding on those first, once your happy then do your drilled & shaped finish
parts. To me it looks like your flame went lean, you went to fast and your
pressure on your regulators may be to high. A common mistake is trying to
force to small of tip to weld heavy material, often by doing this you jack up
your regulator pressure to high. Think of it this way, if you blow on a
liquid metal to hard it causes it to puddle out and disfigure the weld. You
need the right size tip, so you get a hot enough flame with a gentle touch.
Watch your tip flame like you watch your airspeed, it must stay slightly rich
Carbonizing (very important). The part you are welding is difficult because
your flame is surrounded by metal fitting, which will make the tip get hot
and pop, especially if using to small of tip. I am no expert but I hope this
helps, and don't be hard on yourself, good welding comes the same way as good
landings.
Dan

Hi friends
Hi Jim
Welding it's not hard, just practice and more
practice, it's very important that you have the
regulators with the correct setting , adjust the flame
so you have a little acetylene feather (1 or 2
millimeters are ok), so you be sure that your flame
it's not oxidizing and maintain the flame over the
puddle with little circles , and at 45 degrees apx..
so you can maintain the heat on the metal, try that
the blue flame don't touch the puddle, the metals have
to joint, and the rod is for fill the metal lost.
About the time, it's hard to know how many, that
depends on your flame.
I would like recommend you that make some weld works
parts for practice and after check this with a hammer,
and cut some welded parts too so you can check your
work, looking for a good penetration... go ahead.
