Noreast... I gave my copy of the 2004 Hershey book to a member who could not attend. Looking at the 2003 Hershey book, under "Lights/Lenses" there is one "R. Rance Schlenker, Solon, Iowa" listed. The book does not provide a phone number. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Hi, Kestas... I totally agree with staying with cast iron over aluminum. Mentioned this to Harry. As for shrink, we utilize pattern maker's rule of 1/8" per foot and have done so forever with grey iron only. Our 65-45-12 ductile we allow for 1:1, no shrink. 80-55-06 we allow only 1/16" per foot and that is subjective depending upon the "section size". Regards, Peter. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Dave...I totally agree. It's moved. truncatus...Welcome to the AACA Forum. I echo Dave's appreciation for sharing your experience. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Hi, Harry... Only 4 weeks ago, I traded my 2001 Dodge Dakota (4.7 V-8 that had 199,731 miles on it) for a 2005 Dakota. About 12,000 miles on it were towing a 5200 lb. trailer & car. Was running fine. Could have gone a lot further, however, if you saw some of the rather rough neighborhoods where some of my accounts are located, it was traded for peace of mind purposes. That's not to say the new one won't break down, but... Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Scott...why not give the Library & Research Center a try for "factual data"? Your questions certainly are an excellent case example for the L&RC archives assistance.

Hi, Judy... Wayne sent this from the cruise ship. A humongous wave must have slammed into it to explain the typos <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" /> <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" /> (er, uh I can't think of any other liquid that would cause this <img src="http://www.aaca.org/ubbthreads/images/graemlins/tongue.gif" alt="" />).

olamoree...Welcome to the AACA Forum. I can assure you, a few photos will be beneficial prior to assistance. Please submit some. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Aregee...Welcome to the AACA Forum. Please read the mission statement of the AACA as related to your project, then, by all means keep us informed. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

groselle...interesting thread. Now that you are asking for a "value", and, the use has been identified, please make a post within the Buy/Sell section. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Thank you, Harry. I made note of the weight. Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Hi, Kestas... You are correct about aluminum shrinking (typed before thinking). At one time many years ago, we poured the ZA alloys which shrink, however, not as much as, say, 319 aluminum sand castings that do shrink. As for ductile, the majority of what we pour is 65-45-12 and has no shrink. We actually use a 1/1 ratio when building patterns for ductile castings and factor in "no" shrink.

Twitch...out of curiosity, remove the moving Chevy Wagon icon. As Wayne mentioned, normally a large photo will expand the text. Will e-mail our webmechanic to see what causes this. Regards, Peter J.

To any of "we club members", of whom, ever had the exerience of appreciating Kim's dedication to the L&RC, this is truly sad news. Bless you, Kim and Family.

Hi, Ken... Restorer32 and Harry pretty well covered the casting scenario. Have 2 points to add: 1. The fan blade is what is considered "off-set" parting. This means it is not a flat piece with a straight horizontal parting line. In other words, one half of the part is made in the drag (bottom section of the mold) and the top half in the cope (top section of the mold). 2. Aluminum, like ductile iron, does not shrink, so, you should have a fairly near net shaped part. The foundry will probably have to make a "follow board" to create the exact parting line, but, not your worry as a foundry person knows this facit. Good comments from all of you guys. Interesting to say the least. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Ken, thanks for the photo. Know this has been a your nemisis for some time. Up front with you. Your "welded" blade will be out of balance simply by the welds throwing the weight distribution out of kilter. What I cannot see in the photo, is, how "true" is the "round" of the bolt holes. If they are oval shaped from wear, coupled with the weld in-balance, could spell a totally spent part you are trying to salvage. Fan blades, Pump impellor blades, Ship/boat props are probably the most difficult to cast. The "balance" from the raw casting-through-finished part has to be taken into consideration. Good case example I can share: Though the Flywheels were in Class 30 grey iron, it is irrelevant to your fan blade. We were the sole producer (foundry within the U.S. of A.) for Honda's high end $$$ "Harmony Lawnmower" for about 5 years. We would take the "raw" casting, spin balance it, the CNC balancer would indicate the out-of-round areas, the CNC controlled drill press would drill areas on the casting face that were throwing it out of balance, and, then finished product. (I said "were" only because after receiving the President's Award from Honda for over 1-M to-print parts, the Japanese economy soured, and, that's where the Flywheels are now. The Mother Country needed work.) How I see it, and, it is getting late here, is, be certain the blades are aligned as close as possible and as best you can from whomever welded it. The welds can be ground down to "blend" into the contour as best you can, have it spin balanced, then, approach a non-ferrous supplier. Enough tonight...will table your problem and get back. Regards, Peter.

Hi, Ken. Restorer32 has some good points. Should a casting be utilized as a pattern, the "shrink rule is .125 (1/8")per-foot". Grey Iron castings (ferritic micro-structure/flake graphite) will shrink by .125 when the casting is cooling. This "shrink" is factored into a pattern's dimensions. So, when utilizing an "existing" casting as a pattern, obviously, the casting is net-shape, and, the fluid iron when cooling will shrink another .125 per foot. Of note: If the part is Ductile Iron (pearlitic micro-structure) ductile does not have much, if any, shrink. IMPORTANT: I have found that the average person when it comes to castings, believes a casting is grey iron just because the part looks like a casting. A steel forging can resemble a grey iron casting. Well, it is a steel forging for a reason - critical strength! When in doubt, request that a foundry analyze the material just for safety reasons. Should not mean a hill of beans with the average replacement casting, however, will mean a lot if the part is a critically dimensioned internal engine part like a piston, rocker arm, or, whatever. If an existing casting is going to be used as a working pattern, always emphasize to the foundry machined surfaces as they will have to add roughly .120-.125 machine stock, say, on a flange surface. If they do not, your machinist will have "air" to machine, and, then a manifold type casting will not work. Restorer32: Are you going to the Philly Meeting? Would be great to meet you. I plan to go over the above and a lot more during the Friday Sand Casting Seminar. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Folks, I certainly can appreciate your concerns. However, this is not the first time, nor, will it be the last based upon a few years on this forum. The average delivery across the board within the good 'ole U.S. of A., is the 28th of the first month - thru - the 14th of the second month. This is based on my receipt of the AA and posts of years gone by. Patience... Regards, Peter J.

I concur with all the kudos mentioned, Bill. Congratulations!! Regards, Peter. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Glenn... Have to support Wayne's decision here. Absolutely any mention of Mr. Hartmann is an automatic delete. Unfortunately, your responding post makes a lot of sense and I, personally, find it upsetting. Had a guy here in Reading, PA a few years ago, driving around in an early Ranchero "daily". (Not any longer after complaints from we locals.) Bottom line...the mention of Hartmann is an automatic delete and any responding posts. Ask Shawn Miller about his problems with the guy on the CCCA Forum. That's where Hartmann gravitates for the most part. I have blown away similar scenarios when someone (thinking they are humorous on the R&R) by bringing up his PH handle.
