I purchase a set of Pietenpol plans. I thought I would spend some winter days makingsteel parts. I noticed that Aircraft Spruce has a Steel Kit for the Piet.It includes .063", .090" and .125" thick 4130 sheets. When studying the plansI see parts made of .030", .060", .075" and .090" thick material. Can all partsbe made using the ACS kit?Thanks.Harv--------Harv, 485PBRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Subject: RE: Pietenpol-List: Re: Steel PartsOrdering strip steel in 4130 is the easiest way to make most of the fittings andI believe ACS sellsthe various widths needed so you don't have to buy the sheets and have them sheared. It is a littlemore expensive that way but makes part making pretty easy. I wouldn't rely onanything ACS saysis a 'kit' for anything but just go thru your plans carefully one night and notedown in a few columnshow many feet of the various widths and thicknesses you'll need and you'll comeup with a more accurateaccounting I believe of the metal needed to fabricate most of the Pietenpol fittings.Mike C.________________________________________________________________________________Date: Thu, 17 Jan 2013 14:01:03 -0800 (PST)

Although I fabricated a carb-heat system for my Model-A engine, I have not operatedit at high RPM enough to answer your question. What I have experienced atlow to mid-range RPMs was slight to no RPM change. Ive been planning on usinga remote laser-thermometer to check temps at the muff, air duct and carburetorthroat to see what the temperature changes might be.Gene I hadnt heard about the air filter restriction before and will have to playwith that also when I get back to the project.

I believe ACS has a disclaimer at the bottom of their pages warning that the "kits"are based on lists provided to them by others. Because the "kit" lists differentthicknesses than are found on the Pietenpol plans, I wonder if the listmight actually be based on the Grega GN-1 plans, which has different metalworkthan the Air Camper. I would recommend that you spend some time going throughyour plans and do your own calculations of what you will need. And, as Mikesuggested, consider buying pre-sheared strips, unless you have access to ametal shear.In fact, I would recommend that you calculate your own list of materials for thewood as well. For instance, the plywood kit lists more than 7 full sheets ofplywood; there simply isn't that much plywood in a Piet. Finally, you may want to hold off on making all of the metal fittings ahead oftime. Some fittings will need to be made to suit the woodwork that you build.Because these are plans-built wooden aircraft, no two will be exactly the same.And slight differences in woodwork can and will result in certain metal partsbeing required to be made to fit. The difference might only be somethinglike a hole location shifting 1/16" or even 1/32", but that variance can meanthe difference between a part that fits, and one that doesn't. Of course, mostbuilders end up making a lot of fittings more than once. Consider it to bea part of the learning process.Bill C.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Thu, 17 Jan 2013 17:50:20 -0800 (PST)

Listen to the wisdom of Mike Cuy and Bill Church.Spend the time going through the plans and make up your own list. Also, don't forget to go to www.westcoastpiet.comwhere you will find a handy steel thickness gage-to-decimal conversion chart.Greg CardinalMinneapolis----- Original Message -----

Harvey, I'm not a purist. I made all my steel parts from 0.090 4130 steel. If you use just one gauge, it is much easier to determine the length bolt to order/use. I didn't use the thin material and form them into aerodynamic shape and then weld -- I used .090 material for all the control horns mainly because I can't weld and the aircraft welder I am using charges $50 per hour. Might be just a bit heavier than the welded ones, but I'm using a larger engine so can stand a little more weight. My $0.02. Chuck----- Original Message -----
