  1. The 1915 C-25 uses a common pilot ring (P/N 10E830) for both intake and exhaust manifolds per the factory parts list. I suspect that the root cause of the exhaust manifold distortion is a metallurgical phenomena called creep. Creep is caused by mechanical and/or thermally induced stress (load) in the presence of elevated temperature (reduced strength). The stress could be caused by the difference in thermal expansion of the hot exhaust manifold vs the relatively cooler cylinder heads or exhaust system. It could also be caused by residual (internal) stresses in the exhaust manifold caused by differential solidification ("freezing") of the liquid iron during the casting process. It is unlikely the exhaust manifold went through a stress relief heat treat cycle back in the day given the state of metallurgical science at the time (e.g. fatigue cracks/fractures attributed to "crystallization"). Even today exhaust manifolds produced by some manufacturers have significant distortion issues such that they cannot be re-installed without creating oblong holes for the attachment studs.
  2. Olson's Gaskets has repro pilot rings.
  3. Some years ago a friend was restoring a Stutz DV32 for a client (which later got a 400/400 perfect score at a CCCA national meet). He sent the radiator cloisonne emblem to what was supposed to be a "professional" emblem restoration shop here in New England. They ruined it. The emblem was returned highly distorted and unusable; was clearly overheated or constrained when in the oven. I don't think they were in business very long. My takeaway was that it is possible to damage an emblem. If I were to try it at home I think I would use some sort of instrumentation to ensure temperatures are known, research temperatures are required, determine creep strength of backing material (copper, brass or bronze?) which may govern how the emblem should be supported in the oven, and finally develop the process on a less valuable piece.
  4. Hi Ikew, Ed Schillo was the Mercer agent in Chicago who likely sold your Sporting to Mr. Hertzman. Are you showing anything at the AACA Spring Nationals?
  5. Restoration Specialties in PA (www.restorationspecialties.com) also sells Tee rubber seals by the foot.
  6. Not a Buick but I suspect windshield might work the same way. To open for ventilation, the top and bottom panels rotate clockwise as viewed from the driver's side of car; in other words the bottom edges of both panels rotate forward like a venetian blind. The "h" shaped rubber seal between the top of the bottom panel and the bottom of the top panel is fitted to the top edge of the bottom panel with the lip (tall portion of the "h") towards the back. This makes sense in the event of accident that the passengers have whatever protection the rubber seal strip might provide instead of striking the edge of the glass (yes, this car has been retro-fitted with modern laminate glass). There is a handle on bottom center of the lower panel on the aft side. There is also rubber seal along the very bottom to seal against the body, which wouldn't seal if bottom panel rotated counter-clockwise.

    Get yourself a copy of the book "Mercer Magic" by Clifford Zink published in 2015 by the Roebling Museum. This book is by far the most accurate and complete history of the Mercer automobile. The book was thoroughly researched with the help of Tim Kuser (Mercer historian and grandson of the company treasurer) and Fred Hoch. Yes, Mercer did use Continental and Beaver engines - but only in the first few years of production cars. They used their own proprietary engine for the Type 35 Raceabouts, and Type 45 racers where they had so much racing success.
  9. I believe the original post said the car was owned by an individual who lived in Ohio. I don't see any other posts "below this one" discussing California...? In any case, neither chassis S/N 1287 nor engine S/N 1287 show up as a survivor in the roster.
  10. There is an (intern)national roster of Mercer cars/owners kept by a member of the Mercer Associates. The list is not made public out of respect for the privacy of the owners. In 1954 there were 106 cars identified; the current list has just over 140 cars. I don't know when your grandfather sold his car, but I checked and his name does not show up in any of the lists. In order to see if his car survived you really need to know it's chassis/engine serial number or possibly have the names of subsequent owners. You might check with the AACA library to see if they have 1920/21 registration lists for Ohio as they have for some other states. These lists often have the license plate number, owner name and address and engine or chassis serial number.
  11. Terry - As requested attached are 3 views of BAKER rim wedges from a 1915 Buick C-25. Note the faint "W" and "M" on either side of the bolt slot below the "BAKER" text. Paint is modern, color when found was rust. Regards;
  12. Bryan - Unfortunately, your offer came a little too late for me. I know folks may hold their nose, but at the time I didn't think I had any other option to get my next-to-the-barn basket case running again. It turned out that the shell for the C-25 and E-35 are outwardly the same size and style (other than the radiator itself is separable from the shell in later model). I had LA Radiator works here in Maine swap the outlet manifolds and another friend welded up the rivet holes in the sides of the E-35 shell and attach a couple long fender bolts the bottom of the shell so as to mount it like a C-25. So my car now has what looks like a C-25 shell (no brackets) with the later removable core. I got the car running this summer with the help of Mark, Larry and Terry (parts) and I am very pleased with the performance of the radiator (no sign of overheating). At this point if anyone has a C-25 radiator they are willing to part with, I know a gentleman in Texas who needs one.
  13. Heat. I recall heating up similar flange on C-25 gearbox with the puller already in place. Puller not super tight to avoid damage as strength of flange material goes down with temperature. Will likely have to replace felt seal when finished.
  14. It's not a Mercer Series 5 part...
  15. I can't begin to imagine the tremendous pressure that the Hershey Region and the National HQ office have been under in these trying times. I applaud the courage they have demonstrated to make the tough decisions that they had to make. It must be very frustrating to have to operate in such a fluid situation with so many unknowns. Having said that, I had a few less critical, secondary items I thought could be addressed at some point. The events insert with the Antique Automobile magazine that arrived this week is still offering flea market spots for the 2020 fall meet..."Apply now"... potentially confusing. I would suggest some (interim) status info on the Hershey meet is needed in the next issue of the magazine as not all of our colleagues use the internet or forums. Finally, for those of us who have already paid to renew our Hershey flea market spots back in the spring, I have not heard anything about refunds or if the payment will be automatically applied to 2021 (which I would be perfectly OK with). These comments are only intended as suggestions to potentially help improve communications. Having organized a few local car shows myself, I remain in awe of the organizational and logistical effort that must be behind the Hershey Fall meet that agets even better with every passing year. Thank you.
  16. Tim is having a little trouble logging in so asked me to post this on his behalf: The #11 with the 2 guys in it also appears in a photo on David Greenlees' web site, "Old Motor". It's an action shot clearly showing the radiator with that distinctive 11 on it. Much dust, and a big tree right next to the track. No ID as to when or where. I think I have seen a small image of this scene in a book, cannot find it now. The car clearly is a 1911 Raceabout. ID features of the 11's are the longer spring shackles on the front of the rear springs, and the flat spokes in the steering wheel. These spokes were reinforced with a rib on the bottom starting (probably) with the 1912 cars. I say "probably" because Mercer made many running changes in their cars in the early years. The car has Continental rims, and cowl light brackets. Both indicate a stock car. A special race car would have quick-detachable rims and no lights. I wish I could read the license plate on the front axle! I have the photo of the 2 guys in the car, have no idea who or when. I do know that Wishart first drove a Mercer when he was hired by Mercer at Elgin in August 1912. He was assigned to a 1912 Raceabout. The surviving photographs of Mercer race cars show that they never ran last years Raceabouts The had new ones every year. As for the Laviolette photo, the only record I have found shows him setting a new lap record at Springfield MA on 25 July 1914 in a Raceabout. He also won a 3-mile race there that day. The Raceabout #11 in that photo is a 1911. The Continental rims, flat steering wheel spokes, and cowl light brackets all indicate a stock 1911 car. And isn't that motorcycle an Excelsior twin?
  17. Contacted Tim Kuser, he will be signing into the forum with some additional info.
  18. Seems to me the best source to answer this question would be Fred Hoch at Schaeffer & Long in Magnolia NJ. He does not do email or internet.
  19. I will forward a link to Tim Kuser.
  20. Last year had front end shimmy problem at a discrete speed in one of our antiques (not Buick). In our case it turned out to be non-OEM sized wheel bearing on front passenger side was loosening up (slightly). Unfortunately OEM size bearings are no longer available so stuck with the cobbled solution; just need to keep an eye on them now that they stay "tight". Agree with comment above that could be any number of things are slightly loose and/or out of alignment.
  21. Relative to the discussion on roller lifters, on our '15 C-25 project the originals were worn out. We ordered hardened drill guides custom made to order (ID, OD and width) for the rollers and off-the-shelf drill rod for the roller axles, both from McMaster-Carr. First shot shows grinding down the ends of the roller axles, second shot the shows the new parts ready for intallation.
  22. Mr Hammer - The Marvel Carb arrived today. I appreciate the careful packaging. It is exactly as you described. Pleasure doing business with you. THANK YOU!!!
  23. I've been running a NAPA 7212 6V commercial battery in my cars and very happy with both the perfomance and longevity. I keep them in heated space over the winter.
  24. KLF - Front/side views from a few years ago. Cosmetically she is a bit rough with a poorly applied paint job guessing from 60+ years ago and has original leather seat backs and cushions in the back, but she runs great so gets used often. Our Raceabout may come out of hibernation this weekend.
