I'm planning to go this route, but will probably box the step in withaluminum. Careful where you put it though. I put a cutout under the seatin the ply side and found the location was useless once the center wing wasmounted. Looks like about 12-16 inches behind the rear seat back workswell for me. Just about done one laminated ply spar. The 5' sections of plywood werescharfed on a 45deg angle with 3 1/2" wide scharfs. The second layer ofply centers over the 1st layers joint. Still have to put on the fir stipsto bring out the thickness to 1", (using 1/4" baltic birch ply for webs)and the attachment areas will be built up with another two layers of ply.

Subject: Re: Pietenpol-List: Lift StrutsThe struts for my first aircamper are made from 1 1/4 dia by .049 wall 4130 steel tubing from Aircraft Spruce. V sections made from low carbon steel sheet at a local fab shop and MIG welded (weld 3/4 inch, skip 3 inches and so on) onto the round for streamlining and column strength. These are installed without jury struts (I prefer the cleaner look) and they are working very well. There are 77 hours on the aircraft now. I had a structures engineer help me aith all this. ________________________________________________________________________________Date: Mon, 11 Sep 2000 11:40:52 -0500Subject: Re: Pietenpol-List: Step

It's small, sturdy, and would/could fold up into aminimal,non-intrusive recess in the body, perhaps with a small sliding cover,when notin use? That way, it wouldn't interfere with any control cables andwouldn'tinduce so much drag while inflight? You'd have to brace it prettywell where itmounted on the inside, but it "should" work. The idea came to mewhile lookingat a guy climbing into an F-86 at last weekend's airshow...Jay TravisSteve Eldredge wrote:>> I've always wanted to see one with a stirup liberated from a wellworn> bronco saddle.>> sTeve E.>> -----Original Message-----

My apologies to the fellows with dial-up modems. Here are a couple ofpictures of the front step setup. This step is installed in line withthe front of the front seat and ties in to the spruce brace that runsalong the top of the floorboard for the front of the front seat toattach to.Even with the step the front seat is not easy to get into, but I did notwant to cut a door in the side of the fuselage. Most of the loads inthe fuselage are going through the longerons in the area of the frontseat and I just did not want to cut them there for the convenience ofhaving a door. Gary Price has a set of plans for such a door but I'venot seen them.Jack-----Original Message-----

You can use anything you like for the datum - just document it so youcan remember what you used. For aerodynamic purposes, the leading edgeof the wing works best, but that means anything ahead of the LE has anegative arm, so you've got to be careful when doing the math. I usedthe firewall, because it is easy to hook a tape measure to it. Again,everything ahead of the firewall then must have a negative arm, but ifyou're careful, that's not a problem. I then added in the distance fromthe firewall to the leading edge of the wing and calculated my CG as apercentage of the wing cord to establish the CG envelope.Be sure you weigh the airplane in level flight position, preferablyeither inside a hangar with the doors closed or on a perfectly windlessday (you'd be surprised how much a 10 mph wind will change the readingon your scales). If at all possible, use certified aircraft scales(your local FBO almost certainly has a set that he would loan you). Ifirst weighed mine with bathroom scales, then found that my initialweight was off by over 75 lbs when I finally used certified scales. Puteach wheel in the cetner of the pad on the scale - if the wheel is offto one side it won't read accurately. Remember empty weight includesunusable fuel, but no oil in the engine.Jack PhillipsRaleigh, NC-----Original Message-----

I have a question on CG limits. I have just completed the weight and balance calculations on my Pietenpol (Model A engine, one piece wing, see attached). My CG is within the limit of no more than 20 inches behind the wing leading edge - just barely. Is there any value to moving the wing back another inch so it has some margin ahead of the 20 inch limit?Here's the numbers I calculated:Empty weight with oil and water - 710 lbsCG with 200 lb pilot and 10 gallons of fuel - 19.9 in behind LECG with 170 lb passenger - 20.1 in behind LEThe cabanes are already 2.5 inches back from vertical. Theoretically, I am OK with the wing as it is, but would it be better to have it more toward the center of the allowable CG range?Appreciate any thoughts.

Anybody that has incorporated a step...I have found that my Piet has grown a larger tail wheel with each new iteration.And I started this airplane originally when I was about 30. Being 50 now hasshown I am less flexible than before.SO...to put a step under the back seat...I can see it would mostly be a semicircularcut out in the ply for a foot. Did you use any provision such as a tapereddoubler so the fabric is shaped much as the surrounding area. In other wordsjust attaching the fabric to the cutout would make a valley in the side ofthe plane. Thoughts? Solutions? What did you do?Ezra StilesSent from my iPhone________________________________________________________________________________

JohnDan Helsper has a step. Looks like he added a chunk of wood for the fabricto glue onto. I bet it is designed to be just behind the fabric. Can't bethat hard to figure out how the fabric will lay along the side by using along stick. http://westcoastpiet.com/images/Dan%20H ... ep.JPGPaul Poulin has a step too. It also appears to have a wood frame.http://westcoastpiet.com/images/Paul%20 ... _051.JPGIf your looking for something different.Mike Groah has a step but it is a blade sticking out the side.http://westcoastpiet.com/images/Michael ... 40.JPGGary Boothe has a loop type of stephttp://westcoastpiet.com/images/Gary%20Boothe/images/Step_-_1.jpgAt the lower left edge of the picture you can see the step bolted onhttp://westcoastpiet.com/images/Gary%20Boothe/images/IMG_0071.JPGThis is the other side.http://westcoastpiet.com/images/Gary%20 ... --Original Message-----

Ezra,As you can see.....tapered doubler. You mentioned that your tail wheel has grown larger with age, but no mention of your waistline. You might consider beefing-up the longeron to hold the extra weight :O)-----Original Message-----
