i dont have the money to buy them just ask bmoran he will say the same thing but these should be reproduced as they would sell for a lot of money with how many people could use them
I discussed this recasting with Chuck back then. He thought he might be able to find a vendor to do it, but added a caveat that any time castings are pulled the resulting reproduction will shrink slightly. Not sure how that is corrected for. Stu
There are processes that will use a laser to 3d scan the piece into a computer. Once digitized, the model can be go through an algorithm that applies calculations that account for the shrinkage factors of the desired casting material. This modified model can then be printed and used as a casting pattern.
On a side note, back in the olden times, the pattern maker would use special drawing tools that had their graduations marked accounting for the shrinkage factors. For instance, iron has 1/8 allowance over a foot. A pattern maker would use a special pattern makers scale (ruler) that is 12 1/8 inches long in real life, but marked for an appropriately skewed 12". An example would be the Starrett No. 370 Shrink Ruler.
As a final note, the probable reality is that the costs for a set of these adapters will likely surpass the costs of the available custom single piece rims, even if spread out over a handful of customers.

I've got a 3D scanner. If someone has one of these and wants to go through the casting process I can provide the CAD pretty easily.
Time to bring this old thread back with an update. A couple weeks ago our friend Geno C posted a thread over on the 57-60 forum about a ‘53 C-600 near him with a set of the Dayton rear adapters. With his help I contacted the owner, and now have assembled a full set of the 5 x 8” Budd to Dayton wheels. Not sure yet what to do with them, but they are genuine unicorns and the only full set I know of having the 5 x 8” pattern. Stu
I call trips like this “burn and turns”. I think I might have spent a whole 15 minutes at the guy’s very nice place in the north suburbs of Milwaukee. He and I loaded the wheels, I handed him a bank cash envelope, chatted about his new Flxible bus project, and it was back headed south. Maybe we can get together at Iola again this summer. Stu
Finding rare parts is always a good time. Congrats, Stu!
It's funny how perspective can make such a difference on what you're looking at. Seeing the adapters by themselves in the bottom pic, if one didn't know better, they look like they could fit an F100.
Yeah, the picture can be misleading. Darn things, though, would put a major strain on a half ton set of hubs. Each rear has to weigh 75 to 100 pounds, bare. Then another 200 minimum for two rims and tires on each side. I weighed the fronts and iirc they were 50 +/- each. Clearly, fuel efficiency and reduced rolling weight were of no concern in the 1930s.
