| Subject: | Cabane to engine mount struts |
I am using the small aluminum struts from Carlson Aircraft for my cabane struts.
I see Carlson also sells aluminum streamline jury struts. I am curious if you
all think these jury struts would be adequate for the struts that run from the
cabanes to the top engine mounts?

Hey,
I'm getting ready to layup my cowling. Any suggestions as to which epoxy
resin to use? I'm kinda leaning towards longer pot life as much of what
I've ready seems to focus on a race with the stuff curing in the pot.
Thanks

Not sure what you mean by "layup" I've had excellent results with West
System, they have different hardeners to alter the set time.

To weld the or not to weld. That is the question! I have a friend who is willing
to do all the landing gear and motor mount welding for me. He is a non-aviation
guy but is a master welder. I on the other hand have welded once a long

Yesterday I welded several bolts to a small piece of angle iron...to make a little
rack to hold extension cords...
Didn't matter that:
1. A fan was blowing right into the area where I was welding....
2. Some welds were good, some weren't.....
3. The flux core wire I was using in my mig machine probably wasn't matched up
just right with what I was welding....
4. I filled in some good size gaps with big gobs of weld....
5. I did it all about the same way most of my neighbors (mostly farmers) weld up
their plows, etc...
But for aviation welding ALL of those (plus some!) DO matter.
Just make sure (and I'm NOT saying you haven't already confirmed this, I'm just
sayin') that your friend knows the special care to be taken when welding 4130...on
parts that your life will depend on. I found there to be a few gotcha's
that were really surprising.
Again, not trying to be an alarmist...just some things to think about. I went
through the same questions and later found out I should have asked my friend if
he was going to let the welds cool slowly, what kind of rod he was going to
use, whether he would/would not normalize (or whether he actually had the equipment
to normalize "the proper way"), etc, etc.
It's a lot more fun asking those important questions now rather than later....
By the way, if you want to appreciate even MORE what a great welder your friend
is, look at some pictures of MY welding!!! :-)

Shall we begin at the beginning?
Welding and welders certifications and designations are only worth the
value of the organization providing them. And all with their own nuisances. One
would think that a master welder should be able t weld anything for anyone
for any reason. Not true! welding science and technology can be very
specialized where only the most basic of skills are transferable, like striking
and holding a arc. Beyond that its all a different game, fillers, fluxes,
heats, passes all become part of the equation in all forms of welding.
That's not to say you cant trust your friend but you sold know there are varied
differences in certifications and designations.

Sprinkler fitter

atomic
The list becomes as endless as the list of materials. My dad would be
considered a Master welder and yet he knew his limitations and would shy away
from areas he was not completely confident in his skill level and knowledge,
he wouldn't touch the work.
Just my opinion for what its worth, good news is that motor mounts is not
rocket science but metallurgy sure is close.

System Three's clear coat epoxy has a long pot life and wets out really nic
e since it's thinner than other laminating resins. I think it would be ple
nty strong especially in something nonstructural like a cowling. But you c
an check their tech sheet and compare.
It's great stuff to work with.

If you weld with gas (oxy acetyline) you don't have to worry about much of
the stuff that the TIG/MIG guys have to worry about. But it takes a little
practice to lay a good weld and the right rod and torch tip for the job.
Gas welding equip. is much cheaper and in my opinion more versatile=2C but

Well I thought I had a nice looking hour meter in the project I bought from D.J.
till I tried to figure out how to hook it up just now.I didn't get any manuals
with the project but this nice looking Davtron M 800 Chronometer in the panel.
it looks really sharp and I assumed it would function as a hour meter to record
total aircraft hours. but just now I called the factory and it seems it's
main function is a flight timer or such. I need something like a plain old Hobbs
meter.so if anybody needs this thing send me an email.we can talk trade.

I view my Piet project as a learning experience and welding was something I
wanted to learn. I ended up really enjoying welding (as long as I don't have
to do it for a living). Your friend could be a great resource for learning
and inspecting.

There's not much to weld on a Piet? Let's see, there's just the aileron
horns, the elevator horns, the rudder horn, the control system torque tube,
the control sticks, the cabane struts, the lift struts, the landing gear
struts (if using the Cub style gear), the engine mount, the aileron pulley
fittings, etc., etc. Other than that there's not much welding required.

Is there a rule that Sport pilot training must be done in S/P class aircraft? I
met a guy very interested in getting his license and wants to go the S/P route
but there are very few instructors left in the Texas panhandle I know about
to start with and I don't know if any do the S/P thing but I'm trying to help
him find one and an aircraft to rent. Raymond do not archive

There's not much to weld on a Piet? Let's see, there's just the aileron
horns, the elevator horns, the rudder horn, the control system torque tube,
the control sticks, the cabane struts, the lift struts, the landing gear
struts (if using the Cub style gear), the engine mount, the aileron pulley
fittings, etc., etc. Other than that there's not much welding required.

If you weld with gas (oxy acetyline) you don't have to worry about much of
the stuff that the TIG/MIG guys have to worry about. But it takes a little
practice to lay a good weld and the right rod and torch tip for the job.
Gas welding equip. is much cheaper and in my opinion more versatile, but I'm
also comfortable with it. There is not much to weld on a piet, so If you
don't have the equipment I'd say hire it done.

Hi Jack, and you forgot the upper cabane strut fittings; each made of 4 pieces
of steel welded together.
The welding on my Piet was done by a friend who is restoring his own plane, is
a licensed pilot, president of our EAA Capter 124 and a professional welder. He
was laughing the other day; "I didn't realize how much welding there was in
a wooden airplane."

Thank you Mike- that is basically what I got from another source but not nearly
as clearly stated.I wonder if there aren't some flight schools around the country
that specialize in compact training packages that he could attend for maybe
a couple weeks and get the bulk of his training. I know it would not be cheap
yet might be a better option for the S/P class if they have the required aircraft
for training. Raymond. do not archive

Hi Michael,
If you are referring to the jury strut material near the bottom of the page, the
stuff with the .375" minor axis dimension, I personally would not use this
for the braces that go from the top of the cabane to the engine mounts. It might
be strong enough in tension, but if the wing were to somehow try to shift
forward in the event of a crash (ask William Wynne about it), those thin alloy
struts would buckle and collapse far too easily. Just my non-professional opinion
on the matter. I would choose to use the same size material as the cabanes
themselves for peace of mind...

But if you substitute the GA30-612 Riblett airfoil, you will have a much better
flying airplane. Based on his experience (lots of it), and not just theory
and opinion, I'm inclined to believe what he has to say. Here's a clip where he
talks about the merits of the Riblett airfoils and his experience with them...

Snappin' Corvair motors).
Billy,
I checked out the video, and he says that he is also getting better cruse speed
as well? He really makes it sound like this wing design is the best option for
a piet. I mean he even states that he can pull full back elevator with full
throttle and climb?
Sounds like i should invest some more thought into this other design.
Being the guy that I am though I am having some reservation as the plans work and
have worked for so long. But like someone else said... Even BP would have tried
something different if he though it would be better.
Where can I find:
A) Rib lay out?
B) full wig dinesons, with spars, ailerons, and attachment points? Or is the general
wing the same... just different ribs?
Urbana hu? Man us northern IL guys got to get together. ( *head scratch*... I
guess that's why there is Broadhead hu? )
Anyway I'm with ya on the Corvair motor.
OO that's another question:
With the extra HP from the corvair motor, would we benefit as much from the Riblet
design, as from someone who was using a model A or continental?
