Subject: Pietenpol-List: Retractable sliding step
Members:
Here are some photos I made of my step which I created last year. The key
here is light wall tubing slid inside another tube. The buttons are called
step buttons found in aluminum canes or crutches. They will allow for my
step to slide out and lock into the correct 6" length. Then push the button
in and they slide back into the sleeve. I placed this set-up as as far back
as I could under my seat. Used small pieces of ash bolted through my 1/4"
thick floor!
So now... flame away as I added MORE weight to the rear of the fuse! I will
have the nicest easy to get into..outside control horned..looking Pietenpol
"brick" in the country! However, I am keeping it to plans!

No flames ... just a question.
The step button seems like a good, simple method to lock the tube in position.
I'm just curious as to how you will be able to push the button to collapse the
step when you're sitting in the pilot's seat. Maybe you have exceptionally long
arms, or is there a secret?

When calculating weight and balance, where do you locate the arm? in the center
of the cg range? From the leading edge?
and you use negative numbers for distance in front of the datum correct?

Subject: | Retractable sliding step |
The snap buttons came form a local hardware store in Fargo, ND called Mac's for
the whopping price of .25 each. They carry a few different sizes. If you cna't
find them locally, try a store that sells canes and ask if you can buy a few.
The idea works really well and easy to fabricate.
If people need these snap buttons to create a step please advise and I can send
them for costs.

I just lean over the side and push the button and slide it back in. Don't think

Now here's a serious answer to what I think is your question.
1. You can locate the datum (reference point) anywhere you want. For example,
most big planes use an imaginary point in front of the aircraft so that all arms
are positive. Many small aircraft use something like the prop flange, firewall,
wing leading edge, whatever, as long as it can give you a single vertical
reference plane perpendicular to the long axis of the aircraft. Most Pietenpol
builders use the firewall since it's a vertical plane and easy to measure
from.
2. The "arm" is simply a distance from the datum, aft is positive and forward
is negative. In the case of initial weight and balance calculations, you simple
level the aircraft and measure the distance from the datum/firewall to each
of the 3 wheels. Weight x Arm = Moment. Add the weights, add the moments to
get a total weight and moment. Then divide moment by weight and that gives you
another arm. That arm is the distance of the cg from the datum. Then measure
from the datum to the wing and if it falls within the acceptable range, you're
almost done. You now have the empty weight and cg and all other calculations
start from that.
3. To add people, fuel, baggage or equipment, just do the weight x arm = moment
calculations for each item and then add the empty weight and cg info. Just
remember that weights and moments add but the overall arm is a calculated number.
To figure out whether you are withing cg limits in a flyable aircraft, take
just the aft cg items (on a Piet, that's typically just the pilot) and calculate
the maximum aft cg. If it is forward of the max aft published, then you
are good. Do the same with forward cg (typically a "light" pilot as min crew)
and add fuel, max pax weight and do the W x A = M calculations. Again, if
the calculated arm falls withing the cg range, go forth and sin no more. If not,
move the wing until it does.
This is a little like telling you how to build a watch when you just wanted to
know the time but it should answer your question.

is negative. In the case of initial weight and balance calculations, you simple
level the aircraft and measure the distance from the datum/firewall to each
of the 3 wheels. Weight x Arm = Moment. Add the weights, add the moments
to get a total weight and moment. Then divide moment by weight and that gives
you another arm. That arm is the distance of the cg from the datum. Then measure
from the datum to the wing and if it falls within the acceptable range,
you're almost done. You now have the empty weight and cg and all other calculations
start from that.

calculations for each item and then add the empty weight and cg info. Just
remember that weights and moments add but the overall arm is a calculated number.
To figure out whether you are withing cg limits in a flyable aircraft,
take just the aft cg items (on a Piet, that's typically just the pilot) and calculate
the maximum aft cg. If it is forward of the max aft published, then you
are good. Do the same with forward cg (typically a "light" pilot as min crew)
and add fuel, max pax weight and do the W x A = M calculations. Again, if
the calculated arm falls withing the cg range, go forth and sin no more. If
not, move the wing until it does.

Dave thank you, that helps clear things up.

OK.... so i had a leaf from a model a that i cut down and was using as a tail spring...did
a little trimming and bending and ...pow.... broke it
i know there are other options and i've seen them... but i like the leaf spring.
the Ragwing Special i built had an aluminum spring... 1 1/2 - 1/2 inch thick 6061...
bent in a press
i know grove made an aluminum spring for the kitfox..
anybody here ever use aluminum ??
i'll be in Wichita next week and will have access to lots of metal..thought about
doing some shopping for some aluminum to try out
any thoughts ??

I have just a little experience teaching others how to tie this knot. I believe
that If you really want to learn how to do it you have to demonstrate the steps
to someone else. Then you will never forget ! Usually takes less than 10
minutes unless of course your norwegian!

That might be a violation!

I have heard (during a forum at Brodhead maybe?, vicious rumor?) that Mr
Pietenpol went to the coil spring skid after having trouble with the Model T
leaf spring skid damaging the fuselage from side loads. I'm guessing that
it wouldn't be as much of a problem if a tailwheel was used, but maybe if it
was used as a skid? Can anyone else remember more about this tidbit?

The one footnote I should have included is that when you weight the airplane, you
normally include engine oil and unusable fuel when you do the empty weight
calculations.
The one mantra of weight and balance is "Weights and moments add; arms do not".
And for Bill Church, fingers also add.

Jeff,
I believe Zenith 601's are now using 6061 gear legs. I know of at least one builder
of the older HDS model that converted the straight, coil spring gear to bent
6061. As I recall, he just bent the gear legs in a Harbor Freight press. Don't
see why it wouldn't work for a tail spring.
