Early on while I was buying metal parts from Ken Perkins in Olathe, KS he made an offhand comment that caught my ear. He said that if he had it to do over again he would put in a sliding pipe setup that could be slid in and out as needed. I took his idea and came up with this setup. Basically it consists of two pieces of tubing with one that slides snugly within the second. The outer tube is about 8 inches long and the inner about 14 inches. These were scraps at the time and I don't recall the wall thickness but they were not particular ly heavy. The outer tube has a "V" notch cut in one end that the retaining bolt slides into when the step is extended. The inner tube has a washer welded on one end and a retaining bolt near the other end. The outer tube is secured with two metal straps that are tack welded only. Believe me this tack weld is more than sufficient to warp the outer tube which caused me some grief BUT when the straps were bolted down they pulled the warp right out and the two tubes slid snuggly but freely again. I mounted the assembly on a piece of 1 inch ash directly over the 1/4 inch floor ply in the corner where the seat former and diagonal brace meet. This gives lots of gluing surface plus the four bolts which pass completely through the floor with washers and nuts underneath. I have stood on this (all 220 lbs of me) and bounced with no ill effects. I will not make any final judgement on proper placement of the step until I get the wing center section up on the cabanes which, praise the Lord, is not too far down the road. By the way, all the blind nuts on the seat stringers are from a discarded trim system. I do learn - - - eventually.

Sonoma County is home to EAA Chapter 124; and my Piet is not quite as far along as Gary and Mike and Vic's but if you should be blown off course by the great valleys prevailing winds you are welcome to stop here as well. We have a great mexican restaurant, family run as well; La Bufa. Anyway let me know as well where you will be landing as I can make it to most places here in Northern CA in a reasonable time. Cheers and have a good flight whenever you manage to bring Scout North. Cheers, Jim B. ________________________________ Message 5 _____________________________________ Time: 10:01:20 AM PST US From: "Charles Campbell" Subject: Re: Pietenpol-List: Re: for West coast Pieters only Jake, No!, yours is not the smallest. I saw a picture on the British Piet site where a fellow built a Piet in a one-car garage. I'm using a two-car garage and that's pretty tight -- don't know how he did it.

I was going to put my step in almost the same spot. It is too far forward; you will hit your head constantly on the wing center section, or the corner of the wing even if you have a cut out. I moved my to about four inches behind the rear seat back; and if I forget I still bump my head once in awhile. Cheers, Jim B. PS I like the way you did your step though; my is permanently out. ________________________________ Message 7 _____________________________________ Time: 01:33:32 PM PST US Subject: Pietenpol-List: Mitsubishi engine run up with prop!

From: "Pieti Lowell" Chris: You should be congratulated by a great number of Pietenpol Wan-bes. I will be one of them. The top end is an easy cure to get power at full throttle, without burning valves. due to a lean mixture. With the prop shaft extension, a smooth look and an excellent air flow will be a result. What cooling radiator do you use, and where is it placed ? If you keep a good air space between the top of the radiator and the bottom of the wing, it will give you added lift where the air velocity is the greatest. I have a good 10 inches with a cross-flow radiator, flying feel is very different with the added lift, if interested in my installation give me a shout on my Email, Pieti Lowell Read this topic online here: http://forums.matronics.com/viewtopic.php?p=352420#352420 ________________________________ Message 14 ____________________________________ Time: 07:03:33 PM PST US Subject: Pietenpol-List: Re: Mitsubishi engine run up with prop!

After looking over your plane at brodhead, i mounted my radiator the same way. i had a custom aluminum crossflow radiator built for 250 bucks. weighs only 8lbs.

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 lbs CG with 200 lb pilot and 10 gallons of fuel - 19.9 in behind LE CG with 170 lb passenger - 20.1 in behind LE The 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.

Fun work and a good test of my newly acquired gas welding skills. I have a question for those of you who built them to the plans. After zinc chromating them it occurred to me that there will be a large area of unprotected metal inside the horn since the forward end that attaches to the wooden spar of the control surface is open ("butterflied" if you will to attach to the spar). What can be done to protect this bare metal? I thought of spraying linseed oil or fluid film into the opening and sloshing it around. I'm not keen on seeing corrosion on these horns which are so visible on the completed aircraft (not to mention they are a requirement for controlled flight!).
