If that's what you mean, then it can be a suitable substitute for Sitka Spruce (almost identical density, with higher strength). Ask the lumberyard exactly what species they have on hand. Check the weblinks that Chris Tracy posted yesterday, and you'll see Western Hemlock listed in the charts. Go to the Matronics Archives, http://www.matronics.com/search/ and do a search in the Pietenpol Archive, using the word "hemlock". You should find enough reading to keep you busy for a couple of hours. As you read through, you'll see that at least one builder (Clif Dawson) has built almost his entire airframe using CAREFULLY SELECTED Western Hemlock. I can't recall the source, but I definitely remember reading that BHP built laminated spars from carefully selected lumberyard Hemlock. Bill C. ________________________________ Message 9 _____________________________________ Time: 07:38:33 AM PST US From: AMsafetyC@aol.com Subject: Re: Pietenpol-List: Hem fir I couldn't resist googling the hem-fir, Here is a clip form the site and th e link. FYI the official word on Hem-Fir from: (http://www.weyerhaeuser.com/default.asp) Hem-fir is the name given to a combination of hemlocks or firs that share similar characteristics. These include western hemlock and the true firs (noble, California red, grand, pacific silver and white fir)=94specie s primarily found commercially in the Northwest states and British Columbia. Hem-fir design values are nearly as strong as Douglas fir, resulting in an economical and excellent structural product. High ratios for strength and stiffness make it a good choice for framing, and the color of its wood is a mong the lightest of the western softwoods. Hem-fir is a species with excellent preservative treatment characteristics, which makes it an economical option to naturally durable species like western cedars and redwoods. Hem-fir products are available in structural, appearance and remanufacturin g grades. _Weyerhaeuser > Softwood Lumber > Softwood Lumber Species > Hem-Fir_ (http://www.weyerhaeuser.com/ourbusinesses/buildingproducts/softwoodlumber/s pecies/hem fir.asp) ************************************** See what's free at http://www.aol.com .. ________________________________ Message 10 ____________________________________ Time: 09:03:27 AM PST US From: "Oscar Zuniga" Subject: Pietenpol-List: washing the airplane Howdy, Pieters; My airplane's wings sat in a hangar for two years while I repaired the fuselage. Dust, bat droppings, rat droppings, bug stuff, rust drips from the hangar framing, you name it. I have not bothered to clean it up yet but will be doing so before the Hondo fly-in (SWRFI, June 1-2). The Poly-Fiber care instructions say just use gentle detergent to clean the surfaces and a good paste wax to protect them. However... one of the recent Sport Aviation magazines carried an interesting article about newer products that do a better job, so I'm going to give them a shot and will report back on how they work. First product is "Extreme Simple Green", which is supposed to be used to remove spots and stains before giving the whole thing a washing. My airplane has plenty of spots and stains so this will be a good test. The second product is "RejeX", a polymeric coating that goes on after the surfaces are clean and dry, instead of the wax job. Does NOT contain silicones that cause so many problems with painting later on (such as Lemon Pledge, Armor All, etc. contain). Supposed to make it much easier to remove bugs and droppings and lasts a couple of months. The Texas weather will provide a good test for this.

Do a google search and see what you find. Apparently bicycle riders who soaked their chains in the Original Simple Green had cracks casued by accelerated corrosion. OF course Extreme Simple Green is supposed to address that.
