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.

David...that makes sense. Hopefully, you will receive it shortly. Regards, Peter J.

Folks... There were some openings for additional seminars at the Annual Meeting and thought I would take advantage. There have been many numerous posts with casting questions over the years on this Forum. I think it is time to bring it to the forefront considering so many small foundries that had catered to small quantities of castings have fallen by the wayside. I will be giving the seminar from 11:30 - 12:45 on Friday, 2/11/05. For the first 45 minutes +/-, will be a discussion on sources, what you the consumer should do when having a part quoted, and, foundry practice to include reverse engineering of a part. Too much to discuss here. Of utmost importance and a goal is to use this seminar to act as a springboard for the future by way of your input, experiences on this subject, and, so on, to create future dialogue. Somehow, I want to develop a way of communicating all of our discussions on the forum, and, the upcoming seminar to the majority of the AACA membership, of whom, are not into computers and this AACA Forum. Collectively, let's give it a shot to assist eachother with the growing problem of replacement castings. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Dave...I really do not think Steve or the HQ staff should be saddled with answering the delivery. I live only 1 hour East of the Hershey area and just received it yesterday, 1/27/05. The mail system is a wonder unto itself. People here in the Reading, PA area still wonder why a letter mailed locally goes 1 1/2 hours East to Philadelphia, then, comes back to Reading for local delivery. Not all cases, but, a rather frequent occurence. Really like the new format. Also, the 2004 Winners List is really great. Easier to file for the future, easy to see the whole year in one booklet. Nice!! <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" /> Regards, Peter J.

Hi, Bob... Within the immediate region of Reading, PA one can send mail, it goes 54 miles to the Main Philadelphia Center, then, is delivered to the addressee back in Reading. Mind boggling to say the least.

Good photos, Harry. Printed them out and will hold a meeting with my people this week. Have you checked the actual weight? One of the samples you have would be great to actually see how we would "tie" the cores together internally. This is important from a quoting standpoint as 5 separate cores would be more expensive than say 3, if we can eliminate 2 coreboxes via CAD modeling and pattern layout. Will be back on here this week. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Great, Art...always nice to see you. Peter.

Hi, West... Brenda explained the "DF'er" well. The DF Lunch was initiated by Ron Barnett (Ronbarn) and friends some years ago. At that time and through 2003, we had a great time at St. George's Restaurant about 2 blocks away. Had a blast putting a face to a computer. The owner's of the building, of which, St. George's proprietors leased the restaurant area, sold it to developers. In a panic situation in 2003, we opted to "box lunch" at the Wyndham, courtesy of Mike Jones. It is up to the DF'ers if they desire to find a replacement for St. George's and I will table the issue this year. Some find it more convenient to have it in the hotel, others indicated they miss "Philly Cheesesteaks" as St. George's offered. All DF'ers are welcome. It is a relaxed, shoot-the-breeze, lunch. Enjoyable to have everyone state their "Forum Handle" and given name. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Ted...Welcome to the AACA Forum. My best advise, of which, could answer all of your questions, would be to take advantage of the AACA Library & Research Center's enormous archives of unusual, rare, and, accurate historical data.

Location update... Mike Jones contacted me and we will meet in the "Franklin Room". (The Franklin Room is on the mezzanine level. One floor up on the escalator from the lobby level.) Time remains the same: 12:00-2:00 Again, thank you very much to Mike Jones for arranging this. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

Hi, Ron. All forum moderators. I will send a PM. Regards, Peter.

Hi, Harry... I take it you will be at Philly. Great! I attend only on Friday and it would be nice to "talk castings" while you are there. The Moderators have a brief meeting at 1:30 with Terry Bond. Other than that, I will have time to chat. As Wayne pointed out, the Logan Room is on the lobby floor and easily seen. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

That time of year, folks... Mike Jones, despite all of the Annual Meeting logistics he is arranging, graciously took the time and arranged for us to utilize the "Logan Room" on the ground floor of the Wyndham Hotel. The hours reserved for the Logan Room are 12:00 - 2:00 p.m. on Friday the 11th. Mike indicated there may be a "remote possibility" that the room may not be available. Will not know for sure, but, this is the plan. Will notify you of any changes. It was popular last year utilizing the Logan Room with "box lunches" (your nickel) so people could leave one Seminar, join us, then, easily attend the next Seminar/function. All are welcome. Good opportunity to "put a face to a computer keyboard". NOT REQUIRED BY ANY MEANS, HOWEVER, PLEASE RESPOND IF YOU WILL JOIN US... Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

1craig...Welcome to the AACA Forum. On the Main Page, try the AACA Library. The Library & Research Center retains an enormous amount of research information. Do yourself a favor and submit a request for information. The on-line, self-explanatory request form is easy to use. Regards, Peter J.

Thank you, Harry...we'll take a good look at it and get back. Will keep everyone informed within this thread so all can learn. As noted above, sources for replacement castings are steadily deminishing within the foundry business. It would be to your benefit to include as much as possible information to assure accuracy in part replication: --Most of our industrial customers send in CAD Models, prints, or, samples. For the hobbyist, these items are more than likely unavailable, or, not practical. In lieu of the aforementioned, as many digital or 35-mm shots from "all angles" would be great. --Dimensions: As many as you can provide. This is important. --Part weight: Extremely important for accurate quote. Most foundries will over-estimate the weight to keep themselves covered should you send in a "guesstimated weight". Find a way to weigh the part. --Do you have an extra part, or, a broken part that could be used possibly as the molding impression? Extra/broken part that the foundry could slice up to make it easier and more efficient to obtain internal dimensions (cored areas). --Quantities: To drive down any pattern shop work, pattern costs, again, contact friends, marque club members, etc. If your 1909 Watchamacallit needs an exhaust manifold, chances are more than likely another owner would want one. There will always be an old auto owner who needs just one casting, I fully realize this and we'll assist them as best we can. Keep in mind, just because it is a casting does not guarantee it will be conducive to any one foundry. (A parallel example: Our casting weight range is ozs-to-220# =/-. Send in a 300# casting quote request and we will "no-quote" it. There are other foundries set up to handle heavier parts.) Again, we are and have been set up to assist the hobbyist. In the process of introducing my guys to what old auto hobbyist are all about, our hobby's long range problems to keep the autos on the road, and, so on. Have accumulated some manifold photos to inform them of the wide range of part designs that could come down the pike. This tread will remain in the Tech Questions area as its sole purpose is to assist all of us with an increasingly important facit, of which, many have inquired over the years. With the ever depleting resources, especially, salvage yards, we must address the growing problem now. Regards, Peter J. <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />
