I'm headed down to McCormicks Lumber in Madison to pick up some spar material this weekend. Any tips for judging the rough sawn lumber? I'm just concerned that I won't be able to see all I need to see without the boards being planed or having clean ends=2C edges=2C etc. Out of the 4 boards they sent me for my fuselage=2C 3 of them turned out to be spar quality=2C so I know they have the right stuff...Tom B.________________________________________________________________________________

Charlie,For proof, my buddy, Jim Boyer, sent a picture of his wife helping him scrubthe case of a Corvair in their kitchen sink! Simple Green works good, with alittle elbow grease. For $10, a local transmission shop let me stick my casehalve in with their transmissions for cleaning.worked out great!For small parts, I found a gallon can of "green" parts cleaner at a localauto parts supply. It came with a basket large enough to fit in a 5 gallonplastic bucket.let the parts soak for a few hours, then rinse them off.

Many, if not all chlorinatedhydrocarbon materials require the use of respiratory protection and although theodor makes them smell highly flammable they are not. They are however known to produce certain side effects when used in confined spaces like chloroform a old style anesthetic in high airborne concentrations in confinedspaces . When burned may evolve phosgene gas.Any chemical washing should always be done wearing eye protection (safety glasses or chem goggles or full face shields), hand protection and possibly respiratory protection as many of these chemical substances are knownto pose a skin absorption hazard.Petroleum product cleaners, avoid neoprene gloves as they will absorb the material grow and ultimately break down to a point of failure.When ever possible collect labeling information and a search for the MSDS before purchasing or before using the chemical as it may be helpful in making your purchasing decision. do not mix chemicals you are not fully aware of. combining 2 great cleaners does not always make one super cleaner. the combining of an ammonia based product with a chlorine bleach, (Clorox) a sodium hypo chlorate material will evolve toxic gas, chloroamine, in a confined space can cause death.My apologies for this dissertation, however chemical errors are like departure stalls,difficult if not impossible to recover from.The good news is that any chemical substance can be rendered safe or harmful depending upon the users knowledge and willingness to follow the basicrules of chemical safety.Go forth and clean the sermon is ended.Johnsafe in the morning________________________________________________________________________________

Subject: Re: Pietenpol-List: Engine Cleaning MethodsSteve food points, thanks. Glove selections should be made by matching the substance to the glove material you can go to the Edmont Wilson glove site and there should be an application chart that will help with the selection process.Skin is a semi permeable membrane which allows materials chemicals to bass through, that means skin absorption is a major route of entry to the body systems as they pass through the skin the enter the blood stream and are circulated ultimately cleaned out by the Liver they take up residence there and do most of the damage in tumors that often are determined to be malignant. Chronic exposure over time causes subtle changes that you are not awareof until the damage is done, at which point it is typically too late to repair or remediate but becomes a task of monitoring and maintenance treatment.The problem with Livers is ya only got one and you cant live with out it, the chemical toxin scrubber.The good news is, there are several good sources for the selection and use of PPE personal protective equipment and with a little research time you can contact the respirator company, the glove company and the eye wear company for access to their sites that all provided recommended usage tables andinformation.Anyone not familiar with the toxic effects of the chemicals they use have a right, duty and responsibility to learn about them and take the necessary precautions to protect themmselves.John________________________________________________________________________________Subject: Pietenpol-List: Re: Engine Cleaning Methods

Thanks guys... now I am thoroughly scared. Gas welding rig and 28 1/2 wing ribs for sale... cheap! Jusk kidding... thanks for the information. We could all use a reminder now andthen.

You can get the white, non abrasive scotchbrite pads at Home Depot in the rental section. They come in 12 X 18 inches by 3/4" thick for less than $ 6.00. You can cut to fit. ----- Original Message -----
