MochetVelo Posted January 13, 2014 Share Posted January 13, 2014 I'm researching the re-casting of the Hupmobile Model 20 intake manifold. This has been done in the past. Karl bought one from the USA, and kindly put me in touch with the seller. They (having sold their Hupp years ago) are trying to dig up more information about where it came from. Further, I got a quote of $1675 today from an old-time pattern maker for making a new casting pattern. I know an iron foundry near me in Pennsylvania that can do the actual casting reasonably. Anyway, the cost would drop according to the number sold. I know of myself and one other fellow. Anyone else interested?Phil Link to comment Share on other sites More sharing options...
Seldenguy Posted January 13, 2014 Share Posted January 13, 2014 Phil, what are they worth, used of course? I see them once in a while in flea markets but they seem to go unsold. I know of one vendor that has one and has had it for a long time. Of course the Hupp carb is another topic seems like $600 off the car to $1000 restored. --Bob Link to comment Share on other sites More sharing options...
MochetVelo Posted January 14, 2014 Author Share Posted January 14, 2014 Well, finding an original one would certainly save me some trouble! I'll send you a PM, Bob.Phil Link to comment Share on other sites More sharing options...
1910Hupp Posted January 14, 2014 Share Posted January 14, 2014 Hopefully Dianne will come through with a contact allowing use of the patterns used on the one I brought. I've never seen any Hupmobile 20 bits at any swap meet I have ever attended -Would buy just about any original Model 20 Part I could get -Karl Link to comment Share on other sites More sharing options...
MochetVelo Posted January 14, 2014 Author Share Posted January 14, 2014 Until an original turns up, I'll continue with the reproduction idea. So far, 4 people are interested. Plus, we'll put a notice in the next Hupp Locator issue.Phil Link to comment Share on other sites More sharing options...
Max BURKE Posted January 18, 2014 Share Posted January 18, 2014 G,day to all . Phil ,have a think about the hot air tube cast in to the original Hup manifold. If you are not running in heavy frost or snow this hot air is not needed. and you will have eliminated it by dropping the plug out of the bottom of the Breeze. Perhaps the pattern maker would discount the price if he didn't have to make a core box to produce this hot air passage. There must be originals around and even if cut off the missing base bend can be fabricated or cast as a small piece and welded or braised back on cheaper than producing the entire manifold.

MochetVelo Posted January 20, 2014 Author Share Posted January 20, 2014 Yes, Max, it's certainly an option to produce the bottom bend of the manifold only. That is, the part below the carburetor mounting bracket. That would work in my case, I think. I wonder if that would satisfy those seeking new manifolds? Many vintage cars pre-heated the fuel mixture, I suppose because the gas wasn't of dependable quality. Also, if a new manifold were cast, would an "simplified/improved" design such as you suggest be acceptable? Phil Link to comment Share on other sites More sharing options...
MochetVelo Posted February 22, 2014 Author Share Posted February 22, 2014 I tracked down a fellow who says he has some reproduction Hupp intake manifolds made years ago. It may be spring before he can retrieve them from his snow-covered barn, however. I'll post if he finds them.Phil Link to comment Share on other sites More sharing options...
MochetVelo Posted April 22, 2014 Author Share Posted April 22, 2014 The Model 20 intake manifold project continues. I tracked down and hope to soon receive the patterns for a Model 20 intake manifold. I'll have to arrange for the casting myself, but I think our local foundry can do it. I will keep you informed.Phil Link to comment Share on other sites More sharing options...

MochetVelo Posted April 22, 2014 Author Share Posted April 22, 2014 That's nice to know, Karl. There is also a pattern available for the crankshaft, which I think was mentioned earlier.Phil Link to comment Share on other sites More sharing options...
1912Minerva Posted April 27, 2014 Share Posted April 27, 2014 Phil - I would be interested depending in price.Regards,Andrew. Link to comment Share on other sites More sharing options...
MochetVelo Posted April 27, 2014 Author Share Posted April 27, 2014 I'll post the price here when I find out. I'm thinking it will be in the $200-$300 range for the casting. I don't intend to make a profit off of this project.Phil Link to comment Share on other sites More sharing options...
MochetVelo Posted June 2, 2014 Author Share Posted June 2, 2014 The core patterns for the Model 20 intake manifold arrived today. The red pattern is the one I had made. The patternmaker first made the core in wood, then cast it in resin. Here are the patterns I have now:Next, I'll take them to the foundry to see if they can cast it. Stay tuned.Phil Link to comment Share on other sites More sharing options...
trimacar Posted June 2, 2014 Share Posted June 2, 2014 If you have a good foundry, that's great. If you need a "second opinion", I've had a couple of things cast by Mystic Valley Foundry in Somerville Mass (Boston)....very reasonable and good to work with.... http://www.mysticvalleyfoundry.com/ Link to comment Share on other sites More sharing options...
Restorer32 Posted June 4, 2014 Share Posted June 4, 2014 Foundry practice has changed little over the past 1000 years at least. They used to make cores from sand and molasses. A good foundry willing to mess with small orders is a great find. Link to comment Share on other sites More sharing options...
MochetVelo Posted June 10, 2014 Author Share Posted June 10, 2014 The manifold pattern is now at the foundry, so I'm just waiting to see how it comes out. They didn't see any problems, though making the cores may take extra time, as they are blown. That is, the sand mixture is blown into the core mold instead of pushed in manually. I ordered six copies, and I'm still estimating about $250 each. It may take several weeks... or several months. I'm hoping for weeks.Phil Link to comment Share on other sites More sharing options...
MochetVelo Posted July 9, 2014 Author Share Posted July 9, 2014 I got the first three manifolds today. The foundry will cast a couple each week. They are un-machined, of course, but look good. I can't visually check the inner dividing wall, but it seems airtight. I'll have a price when they are done.Phil Link to comment Share on other sites More sharing options...
