Subject: | Building is No FUN some times |
It's now 12:45am and I just walked in from the garage after fighting with
installing the tires on my 21-inch wheels. 4 hours and two ruined tubes
later, I finally have the wheels done, good thing I bought 4 tubes just in
case. I chose to assemble my wheels all myself and man what nightmare.
Ended up lacing and truing them two times each, and re-lacing one again
after that. I have gotten quite good at it now, one wheel only takes me
about 2 hours from start to finish. Mounting the first tire took 3 1/2
hours and three tubes and the last only took 1/2 hour and one tube. Tip, do
not use tire irons, use a rope two hands and a foot. Throw in the large
amount of money I have invested in these wheels and I am really hating these
things right now. I know I will change my mind eventually but right now they
are in the dog house!
Sorry to vent, but MAN this building thing really stinks some times.

Subject: | Re: Corvair intake manifold (Bernie's design) |
Of course I would post this question last night, and after a few minutes this morning
poking around I run across a picture looking into the rear of 899H's cowling:
http://www.builddiary.net/images/logs/21/fullsize/IMG_0387.JPG
Ok, now that I can see that, can someone take a look and confirm what I think I
am seeing? There is a vertical tube behind the engine. It runs directly behind
the chafe tape w/ zip-tie that is on the angled engine mount member. This would
appear to me to be part of the intake manifold. As I follow it down I see
it steps down in size, and then I can just make out what appears to be the carb
flange, mostly hidden behind the horizontal engine mount member.
The manual instructions say that the manifold is made of 1 1/2" OD steel tubing,
and the jacket is made from 2" tubing. After viewing this pic, and reading that
description again, my initial conclusion would be that he slipped the 2" tubing
over the 1 1/2" tubing, cut circular "caps" to enclose the ends of the 2"
tubing, and welded this all together. I would then guess that he would run oil
through a fitting into and out of the jacket. I can barely make out what appears
to be an oil line attaching to the top of the jacket on the side facing
the camera, and another line running behind the jacket in roughly the same location.
This all raises another question: would he run warm oil into, and take cool oil
out of fittings that are both located at the top of the jacket? After the jacket
is filled with oil I would think this would not promote circulation of the
oil through the jacket long enough to do any good. In addition, why would those
three copper tubing lines, assuming they are oil lines, need to be run to the
firewall like that?
I hope I'm not missing something completely obvious here. Any thoughts on the matter
would be appreciated. Thanks, and have a good day,
Ryan

If you are going to use a corvair engine spend the money and buy William
Wynne's conversion manual for the engine. Many improvements since Bernard
first used one as well as a good guide to witch engine year/model and the
specifics on how to accomplish it.
www.flycorvair.com
to catch on to many of the idiosyncrasies of the corvair you may also want
to read up on and lurk on the Crovaircraft list at:

> Hello all,

> Had a fantastic weekend at the MAAC fly-in at Brodhead. My wife had never
flown in a light airplane before, and through a confluence of coincidences
she was able to take her first flight in "The Last Original" with the woman
who used to own the airplane years ago, who is a friend as well. This was
particularly perfect, as last month we received our own set of Piet plans,
and we are going to use the Corvair. And her opinion of the flight: she
loved it! Needless to say, I'm ecstatic. She was enthusiastic about it
beforehand, but now she knows she likes it, so she is even more gung ho
about building and flying our own Piet. I'm a lucky man. :) Many thanks to
Bill Knight, who was gracious enough to allow her to go flying in his
airplane. Later on he also allowed me to climb into the airplane and see how
it fit, and I must say that I was pleasantly surprised that I was not
cramped. I'm not extra tall (5'11"), however I'm not small (220, 44" chest).
Reading some of the postings !
> about cockpit width had me worried, thankfully for no reason. Anywho, on
to my question....
>
> I've been reading through the builders manual, and thinking about how we
will convert our Corvair. I rather like the idea of sticking to Bernie's
conversion. It's relatively simple, has thousands of flight proven hours.
Plenty of time before we completely make a call on that. One of the things
in the process I was wondering about was the design of the intake manifold.
Bernard indicates that the intake manifold is jacketed, and engine oil is
circulated through it in order to heat the manifold, and cool the oil. If
it's not an utter bear to construct, it would seem to be a good way to heat
the manifold to reduce the susceptibility to carb ice.
>
> Unfortunately there is no picture or drawing of this that I have found,
and I do not know exactly how one would go about fabricating such a setup.
Might anyone have an eye-witness description in a bit more detail, or better
yet some photos? I wish we had been able to pop the cowling on the "Last
Original" at Brodhead, but we didn't ask at the time because we did not want
to be a bother with everything else that was going on. Maybe on the next
trip up.

Subject: | Re: cut steel parts |
Brian,
For what its worth, I just had all my metal done in CAD. I sent them out for
laser cutting, out of 4130 stock. It should be interesting to see what I get
back. I believe my quantities may be excessive so I expect a bunch of extra
parts also. According to my guy there is a good chance my parts may be cut
this week, I remain hopeful and excited to see them arrive. Then its off to be
coated/painted I am not certain about that part of the process yet but I am
looking at the alternatives.
Not sure if anyone may be interested but figured not to offer my excess
parts for sale until I get all my metal bent and finished counted and verified.
I
am sure there may be others interested in speeding up the metal process.
Since I have all the CAD drawings on CD in the 2 formats I was considering making
them available for sale as to off set the development costs of getting them
done if anyone is interested?
I saw some for sale at Broadhead also, not sure if they sold but was curious
as to the paint coating needed for all the metal parts as the typical
treatment. I am also considering powder coating them not sure which direction I
will go. Obviously paint weighs less than powder coating, what is the general
conscious for metal parts coatings?

Michael,
Thanks for the advice. I do have a copy of the manual (borrowed from a friend to
thumb through before I take it back when I go to pick up my core from him in
two weeks). I'll order my own copy (and see how long it takes to show up) before
we order parts, as I'll need to send in the disclaimer from the manual. We
will follow his minimum recommendations for many aspects of the rebuild (forged
pistons, ARP rod bolts, etc). I imagine we will buy a few parts from him, such
as the oil pan, maybe the safety shaft.
We're building a hand-prop motor, so we won't need his starter setup. I plan on
keeping the alternator in the rear, so we won't need the brackets. Because we
won't be using a front alternator, we have no need for the gold hub w/ the pulley
groove that he sells. If I'm not going to need use the front pulley, then
I do not want the prop hub being any longer than necessary (no need adding extra
stress on the crank), so we'll stick to the Pietenpol design there as well.
We'll fab our own exhaust, so on an so forth.
I have been lurking for a bit on the Corvaircraft mailing list, and it is a very
active and interesting source of information and opinion.
Thanks, and have a good one,
Ryan

Remember the comments about making certain parts a bit longer than called
for in the plans. Mike Cuy and Chuck Gantzer both mention this in their
videos and point out various locations where it makes a big difference in
being able to fit bolts through the fittings and to work with the nuts on
them. Parts like the wing strut attach fittings that stick out the bottom
of the wings, if made to plans, put the attachment hardware right up against
the fabric covering with no room to work. Lengthen them a bit, like these:

I am avoiding laser since it heats the metal and hardens the edges. The
turret punch leaves some slight scallops on some curved edges, but then can

How about a water jet cut part? I don't think there is any heat
involved in that type of cut. Also would a punch introduce stress in
the metal?

Subject: | Re: cut steel parts |
Unless I am missing a critical piece of information, laser cutting heat is
concentrated and localized to the edges of the material. That means edges are
harder and less prone to wear at the edge which could be a positive note when
considering holes would be treated to prevent wear.
Areas where hardened edges are not wanted or warranted can always be ground
or filed off as I suspect the heat would be concentrated and localized to a
small area which can be ground or filed off as needed. Not unless I am missing
some critical piece of information, in which case please advise, (Piet
Builder in training and learning new things daily).
I think, I would prefer to file a little than cut a bunch, just my
uneducated opinion for today and subject to change based upon a more pragmatic
and
empirical approach.
Thanks

Looks good, but I have to ask the obvious question. Do you plan on never
flying off of a paved runway?
I guess that if you wanted to keep the original skid and occasionaly fly off
of a runway you could make yourself a bolt on full swivel wheel that can be
removed.

Brian,
I've got quite a few hours logged with a tail skid...around 50 or 60 hrs.
Very noisy, though...sounds like you're dragging a pop machine across rough
concrete !! Over half of those hours was without brakes. During the first half
of '03 I installed brakes, and flew to Brodhead / Oshkosh with the hydraulic
heel brakes, and a tailskid. Take off on hard surface isn't too difficult in
light wind conditions, because the rudder becomes effective as soon as some prop
wash flows over the rudder. Landing on a hard surface with a tail skid is a
totally different story. Not much propwash during the landing phase.
Difficult to control the roll out with the brakes, because it kept tending to lift
the
tail back up each time I stabbed one of the heel brakes, to keep it straight.
Two times, I ran off of a runway while landing (missing the runway lights)
during that cross country trip from Wichita KS to Brodhead / Oshkosh. One of
those landings was a pretty stiff crosswind. Taxiing on hard surface with a
tailskid is difficult, at best, with any wind at all. However, keep the
tailskid on the grass, and it poses no problem at all during taxi, on take off,
or landing...with or without brakes...just gotta stay ahead of the plane !!

Ben,
I have had both the lifting of the right wing and abmornal pull to the
right. I found the right brake was draging. After correcting that the plane
still goes to the left a little more than I think it should, and I have the
right wing come up also.
As the tail is lifted the aircraft seems to feel as if you are on ice with
little control. Once the tail wheel is back on the ground you have very good
contorl again.

Subject: | Re: Corvair intake manifold (Bernie's design) |
Vi Kapler used to sell those intake manifolds like Mr.Pietenpol used to
make. If Kirk Huizenga is still on the list, I believe he had one for sale
some time back, might still. It is wrapped with an oil system to heat the
intake manifold while cooling the oil. I believe Wm. Wynne has tried them
and was not too impressed with their functionality, but you should call and
ask him about them because I might be mistaken. Those lines could be oil
pressure to a guage, oil temperature to a guage and primer to a pump to the
manifold.

> Had a fantastic weekend at the MAAC fly-in at Brodhead. My wife had never
flown in a light airplane before, and through a confluence of coincidences
she was able to take her first flight in "The Last Original" with the woman
who used to own the airplane years ago, who is a friend as well. This was
particularly perfect, as last month we received our own set of Piet plans,
and we are going to use the Corvair. And her opinion of the flight: she
loved it! Needless to say, I'm ecstatic. She was enthusiastic about it
beforehand, but now she knows she likes it, so she is even more gung ho
about building and flying our own Piet. I'm a lucky man. :) Many thanks to
Bill Knight, who was gracious enough to allow her to go flying in his
airplane. Later on he also allowed me to climb into the airplane and see how
it fit, and I must say that I was pleasantly surprised that I was not
cramped. I'm not extra tall (5'11"), however I'm not small (220, 44" chest).
Reading some of the postings !
> about cockpit width had me worried, thankfully for no reason. Anywho, on
to my question....
>
> I've been reading through the builders manual, and thinking about how we
will convert our Corvair. I rather like the idea of sticking to Bernie's
conversion. It's relatively simple, has thousands of flight proven hours.
Plenty of time before we completely make a call on that. One of the things
in the process I was wondering about was the design of the intake manifold.
Bernard indicates that the intake manifold is jacketed, and engine oil is
circulated through it in order to heat the manifold, and cool the oil. If
it's not an utter bear to construct, it would seem to be a good way to heat
the manifold to reduce the susceptibility to carb ice.

> Unfortunately there is no picture or drawing of this that I have found,
and I do not know exactly how one would go about fabricating such a setup.
Might anyone have an eye-witness description in a bit more detail, or better
yet some photos? I wish we had been able to pop the cowling on the "Last
Original" at Brodhead, but we didn't ask at the time because we did not want
to be a bother with everything else that was going on. Maybe on the next
trip up.

Dick,
I have the same setup as you discribe, so I'll look into this and make
the proper adjustment. This make sence to me as what could be my
problem.
I also have the tail hook for securing the aircraft while starting with
the release cable that is also conected to the left tail wheel cable. I
might have a second problem there.
I do thank you for your input.

I had the same problem with mine, a straight axle, wire wheels, but a
A-65 engine. But first, a basic rule with the Piet is that EVERYTHING
makes a diffrence.
I had rudder cables that went from the rudder bar to a point behind
the seat where I had joined them to the tailwheel, a "Y". When I would
taxi and lift the tail, the plane immediatly would veere to the left.
This caused me to run off the runway a couple of times. I found that
the tailwheel springs were storing energy and when the tail lifted, the
rudder would shift. I replaced the cables with dual cables from the
rudder bar, problem solved.

Question to the group I have Don Hicks piet N920Y with the model A
eng.
While working my way up to take off speed by doing several taxi
test, I find the aircraft keeps trying to pull to the left.
I have several thousand hours of flight time and have owned two
trail drager aircraft. But this one has a funny feel.
I have the stright axle, with wire wheels.
Any thoughts???
Thank you for your time Chet.

Gene,
I did have the draging brake but have fixed that. Also thought of the
heat issue and check both side, both were cool after over 30 mins of
taxi time.

Almost sounds like you have a brake dragging. Might also want to
check your hub for heat after a run.

Chet There is one more thing now that you mension the lifting of the
right wing. Do you have gap seals on your elevators? The wider the
gap, the more the effect. When I first started flying mine, the tail
was hard to get up and right wing wanted to raise as it was going off to
the left.
Try some duct tape on the elevator gaps, it may be a huge difference. I
had a 3/4" gap.

I have been wrestling with my new 3 piece wing, trying to get it
correctly aligned and to put in the proper washout on the tips. Today I
stopped in Sears and found a level with a digital read out to the tenth
of a degree. It also has a laser. I was able to fine tune the wings
and the $50 was well worth it.
Also, I had final airworhyness inspection on friday and passed. I'm
hoping for first flight this weekend.

Are your bungee cords tight enough? Maybe Jack or Mike will chime in and
