Glen,
You chould use mild filler rod,
And make sure that you let the piece cool in still air (very important)

Thanks guys. I'm using my largest tip right now (Harris #2). Using R45 which
is mild steel filler rod same thickness as the smallest piece I'm welding. I'm
going to try going up to 10lbs Oxygen and 10 lbs Acet. I've been keeping it
set at 7lbs. I'll pick up the next larger tip and see if that helps. It may
be just a matter of getting enough practice. Thanks for coming back with some
good suggestions so quickly.
Heading out to finish the current project right now.

Glen,
My thoughts on tip size is kind of the other way. Think you have to go to a
smaller tip. Each tip is designed to have a certain minimum flow through it,
to not allow the burn to chase up inside. I used a Victor #0, i think, for
most of what I did. Had to go to #000 for the thin stuff.
Again, quoting my Mentor, The tip has to have the right amoumt of flow
through it, which also causes the air on the outside of the tip, to travel
down the length of the tip, and join the mix. This causes all the burning to
go in one direction.
Kind of like the spiral fins on the side of a verticle smoke stack. The
fumes exiting the end cause a low pressure area, that causes the air around
the outside of the pipe to rush up to fill it. On the way up it is made to
spiral, kind of like rifleing in a gun barrel.
Try a smaller tip

I found that too much OX will cause the pop you are talking about. Watch the
flame tip as you add OX to the mix. You bring the flame down to the single
diamond, then back off the OX so that there is some flame past the diamond at
the tip. To much ox will cause the metal to burn (pop) to much fuel will cause
soot to form on the surface.

I'm not an expert welder, even though my life will some day depend on
it, but my experience matches Walt's. I've seen most of my popping
using the torch with the gas turned down too low. How much oxygen you
use should be a relatively fixed ratio to give the proper flame shape.
This a very important part of welding. I attended a welding workshop
at Sun-N-Fun a few years ago, and the instructor spent 15 minutes
showing me how to adjust the flame. Too much oxygen gives you a sharp
pointed inner cone that puts too much oxygen in the weld and could cause
your brittleness. If you haven't already, get a copy of the Finch
(Robert or Richard) book on welding, and he gives a lot of good
advice.I use the "0" tip for nearly everything on the Piet, unless the
metal is close to 1/8 inch thick, like landing gear legs. I use a chart
I picked up at a welding store that recommends tip sizes.

Corvair engines for the later models (1965-1969) came in 95, 110, 140, and 180
hp, and further more subtle differences. 95's didn't come with turbos, only 180's,
so your seller obviously isn't up on their Corvairs. I believe William's
recommendation is to use a 110 (William, are you there to comment?) I've been
really sick the last couple days, so I'm not firing on all eight (or six, if you
prefer) as I try to hack up a lung and type at the same time, but if you're
going to tear it down to the mains anyhow (and you will want to), the 95 and
the 110 are to my recollection very similar. The're both pretty stout engines.
The stock 140 will have four carburetors and is unsuitable for your purposes.
The 180 will have the turbo and some rather distinct variations to support it
(as compared to the other engines); it is also unsuitable for your purposes.
If you can get to the car, there's a small casting that mounts to the rear of the
engine that holds the alternator, oil pressure sender, fuel pump, and oil filler
tube (an old friend calls it the holds-everything bracket). Nestled down
in front of that casting and behind the top shroud is an exposed section of engine
block with the engine code stamped on it. You may have to dig through leaves/grease/mice
nests/etc to expose it. I've got a little x-reference book called
the Corvair Junkyard Primer with all the codes listed in it and I can tell
you which engine you're looking at if you reply back to the list with it. You
also can't discount that people have swapped engines on cars so much the engine
might not be a match for the car model/year, not that you really care. Just
be aware that anything goes sometimes with finds like this.
Also, bring a wrench (13/16", if memory serves), put it on the end of the crank
and try to move it a little. If it isn't frozen, your chances of the engine being
good are better.

John,
William Wynn's manual lists the serial numbers that are recommended good re
build candidates. It would be a good idea to have those handy to help you
make a decision on this purchase. I have helped to remove one Corvair engi
ne from a car and can tell you its a bear!! If you contact your closest CO
RSA chapter they are great at leading you to a supply of corvair engines of
ten which have already been removed from a rusted out "donor".
I was able to locate a good core for a hundred bucks within a twenty minute
drive from my home!! If you haven't purchased WW's manual ($60.00) I woul
d highly recommend you do. If you are just looking for serial numbers for
now I can extract them from my copy. Good luck.

Although you are technically accurate, and by no means do I want to sound
disagreeable, but when a car has been available to "mechanics" for over 40
years, there are no guarantee of matching equipment.
The reality of it is, a 180 turbo induction system (including exhaust) will
bolt to any model head (long block), from and early 80hp up to late 180hp
9and it would run), excluding the 140; but I suppose that if one were to
bock off the second set of intake ports (carb base flanges) one could also
bolt a turbo to a 140 and it would also run.
Not that anyone in their right mind would do this, and no telling how long
it would run before it detonates itself... but you never know.
I wrote this a few years ago. It may help.

Lots of years ago I spent an entire week at Osh doing the composites
workshop and had time to hangout with the volunteer instructors at the
welding workshop. If memory serves me, they insisted the flame had to be
slightly rich in fuel and lite on the oxygen. The flame was adjusted just
down to the diamond blue tip and then backed off on the oxygen to make a
"carbon rich flame". Reason- the excess oxygen in the flame would burn out
the 0.30 % (I think, that's what the 30 stands for in 4130) carbon thats in
4130 steel, leaving a weaker weld. If the flame is oxygen rich the carbon
burning up in the steel making CO2 gas will make the weld pop and bubble up.

John,
Make sure you purchase the correct corvair engine listed by William Wynne. There
are certain models to stay away from....And Ibelieve one of them is the turbo
charged designed?...I was going to use a corvair in my application...(another
story for another time) But I do remember in his conversion guide he makes
mention of specific engines that will work for his conversion...
Hope this helps before you spend $$ on a wrong engine model...

John, Having rebuilt our corvair engine 2 1/2 times I can give a little bit of
advise. Your best bet is to first get the wynne mannual, and the Finch corvair
mannuals, and also the GM mannuals. Then locate a 1965-1969 non turbo engine.
Wynne's mannual tells which ones to stay away from, DO YOUR RESEARCH, AND
CHECK PART NUMBERS ON THE HEADS, THE EMISION FRIENDLY VERSIONS ARE HAZZARDOUS
TO YOUR WELL BEING.. From experiance I recomend NOT using the 1964 engine. The
heads and cylinders are different than the 65-69 engines, and 65-69 are interchangable.
The 65-69 heads and cylinders are "beefier" than the 64. I would
also recomend buying a set of jugs, and pistons (forged) from clarks corvair,
You will have to have a head shop install the wrist pins in the piston and
rod, unless you have a rod heater, it doesn't cost too much. We found out the
hard way about making sure the heads are good. If you buy an engine make sure
the sparkplug holes are clean and not helicoiled.
We have 16hrs on the new engine and all is well. The head was the culprit that
caused or contributed to a broken crankshaft after 60 hrs, and burned up the
#4 piston 5 hrs after rebuilding with a nitrided crank. I am starting to get
more comfortable with the corvair, as we had some major let downs, but they
were all out of the ordinarry wierd problems we encountered. Feel free to e-mail
me off list if you have any other questions.

in the last 3 weeks. I saw Skipp Gadd there, he flew his 172 in on sat, looked
like a good turn out but I got there just before "Go Home Time". This would
be another good unofficial piet fly in in the future, no asphault, just dust
and grass. Now all I have to do is start flight testing with weight in the
front cockpit, Then I can stay out longer if I bring the wife along. Hope you
all have a wonderfull Labor Day.

Where is this car? I've had my eye out for a decent late-model body.

Been there.
My '66 Ultravan came with a '61 distributor and the numbers on the rods were backwards
(6-1 instead of 1-6), which I didn't find out until one of the rods shot
through the crank cover.

This list is the best! Where else could you throw out a question to the world
before bed and wake up almost expecting some kind of help. I took Dan Wilson's
advice. With regulators at 7 lbs. I opened the acetylene wide open, then opened
the oxygen wide open and backed down the pressure at the oxy regulator till
I saw a nice neutral flame. Cone was clear and a little larger than I'd been
seeing before and made nice puddles with no popping and able to weld straight
through in one pass. I think with #2 tip it was a little too much heat so
I'm going to take Walt's advice and go back down to the #0 tip. Thanks to everyone,
I really enjoyed reading each suggestion and the remaining welds show that
the advice from this list is fantastic.

John, Having rebuilt our corvair engine 2 1/2 times I can give a little bit
of advise. Your best bet is to first get the wynne mannual, and the Finch corvair
mannuals, and also the GM mannuals. Then locate a 1965-1969 non turbo engine.
Wynne's mannual tells which ones to stay away from, DO YOUR RESEARCH,
AND CHECK PART NUMBERS ON THE HEADS, THE EMISION FRIENDLY VERSIONS ARE HAZZARDOUS
TO YOUR WELL BEING.. From experiance I recomend NOT using the 1964 engine.
The heads and cylinders are different than the 65-69 engines, and 65-69 are
interchangable. The 65-69 heads and cylinders are "beefier" than the 64. I
would also recomend buying a set of jugs, and pistons (forged) from clarks corvair,
You will have to have a head shop install the wrist pins in the piston
and rod, unless you have a rod heater, it doesn't cost too much. We found out
the hard way about making sure the heads are good. If you buy an engine make
sure the sparkplug holes are clean and not
helicoiled. We have 16hrs on the new engine and all is well. The head was the
culprit that caused or contributed to a broken crankshaft after 60 hrs, and
burned up the #4 piston 5 hrs after rebuilding with a nitrided crank. I am starting
to get more comfortable with the corvair, as we had some major let downs,
but they were all out of the ordinarry wierd problems we encountered. Feel
free to e-mail me off list if you have any other questions.
