Chris Durkee 1 Posted October 14, 2018 Alsfarms, any body parts for a 1927 8-80? I need the sedan body from the cowl back. Any leads would be greatly appreciated. Chris 1 Share this post Link to post Share on other sites
alsfarms 63 Posted October 15, 2018 Hello Chris, Are you involved with the Durant Club? It may be that body works from another of the Durant offerings would be similar enough to replace your missing sedan body. It may also be an option to check on the possibility that a Junior 8 Locomobile sedan body could be fit to your 8-80. At this moment I have no information on loose or spare body parts for your vintage Locomobile. However, should I run across or hear of any possibilities suitable for your Locomobile I will pass along that information. What state are you located in?

locoman 12 Posted October 17, 2018 Pretty sure that this radiator cap project has already been done. Chris Figge from Ohio did it for his car, 1911 model 48, same cap. He also did an article in the Horseless Carriage Gazette about them. Maybe about 7-8 years ago. Locoman Share this post Link to post Share on other sites
alsfarms 63 Posted October 17, 2018 I am trying to locate the exact Gazette issue to refresh my memory on how Chris did his project and what material he used. Time moves on from 7 or 8 years ago, and there is now a need again for a few of the Locomobile Bakelite style radiator caps. Al Share this post Link to post Share on other sites
Terry Harper 92 Posted October 19, 2018 (edited) Hello Alan, I have a scanned copy of it and will forward it to you. I just need to finds it! I am pretty sure its on my school computer. It's a pretty straight forward process using silicone molds and colored phenolic resin castings to simulate the bakelite. I have been working on one for Joe. His is a modified version of the one shown below. We currently have the 3D model now I need to either 3D print or CNC the master. Cheers! Terry P.S. In regards to the Wisconsin... I finished and painted the patterns and core boxes for the rear water manifold and have most of the pattern pieces printed for the front fitting. Its a slow process but they are looking great!

alsfarms 63 Posted October 20, 2018 Hello Terry, Thanks for the forwarded information on home casting the reproduction radiator caps, Locomobile and others as needed. I need to call the listed source to verify that the material can take the heat generated by the radiator. Also, what provision needs to be made to protect the material from the suns UV harm. Your Wisconsin water manifold update does sound great! Regards, Alan Share this post Link to post Share on other sites
Terry Harper 92 Posted October 20, 2018 Hello Alan, I know the article didn't address it but there should be a threaded brass insert. My plan for Joe's was to either encapsulate the brass insert when I pour the resin or mill the resin casting and epoxy the insert in place. 1 Share this post Link to post Share on other sites
alsfarms 63 Posted October 22, 2018 (edited) Terry, I have the idea that I will machine out the actual brass threaded insert and knurl the OD. I will then make the rubber pattern, prep and pour a blank cap. I would then set up and machine out the ID of the cap to accept the brass cap and epoxy them together. I can see more issues with pouring the two pieces together, at one time, than I am willing to deal with. After I get a good handle on the casting method, I have several other antique auto's that need to have replacement caps built. If it is not one thing, it is ten others.....

Terry Harper 92 Posted October 22, 2018 That would work just fine. T. 1 Share this post Link to post Share on other sites
alsfarms 63 Posted October 22, 2018 Hello Terry, Have you done any research as to the temp rating of the finished/cured resin product and how it will be affected by UV rays for the radiator caps? Alan Share this post Link to post Share on other sites
Terry Harper 92 Posted October 23, 2018 (edited) Hello Alan, I have not. When I get back into it I was planning to call the manufacturer and see if they have a recommendation. I know they offer several types of resin for different applications. I also have an article were a firm reverse engineered the distributor cap for a V12 Liberty engine and were casting them out of resin as well. Their only issue was the resin was somewhat brittle so they had to develop some unique steps in the manufacturing process. I just e-mailed the article to you. You never know when the info will come in handy! Best regards, Terry Edited October 23, 2018 by Terry Harper (see edit history) 1 Share this post Link to post Share on other sites

Terry Harper 92 Posted October 23, 2018 Hello Alan, I was just looking at the Smooth-On website. They offer a bunch of different resin products for different applications. In regards to heat resistance they have EpoxyAcast 670HT which can withstands temps up to 350 degrees depending on how its cured. They also have UV resistant pigments and additives. I am thinking it would be best to call a rep to discuss what would work best but this might be a good place to start. All good fun! Best regards, Terry PS: here is the model of the cap for Joe. I think we are going to loose the script in the middle since he plans to use a moto-meter 2 Share this post Link to post Share on other sites
alsfarms 63 Posted October 25, 2018 Hello Terry, The new reproduction cap should make Joe a happy boy. Are you close to pouring a rubber pattern? Al Share this post Link to post Share on other sites
Terry Harper 92 Posted October 25, 2018 Not yet! But we are getting there. This project sort of fell to the bottom of the que but should be at the front once I get these patterns and core boxes for the Wisconsin out of the way. T. 1 Share this post Link to post Share on other sites
alsfarms 63 Posted October 27, 2018 Hello Terry, Like your other projects, It will be nice to see how you complete the Mitchell radiator cap project which is so very similar to the Locomobile cap I need to make. I need to spend some time on the phone with someone from the Smooth-on company and learn for myself what materials are best to use for my application.
