I have the crazy idea that I'd like to build a 1/8 or 1/12 scale R4360 display model. I have done some checking and none of the cylinders from any of the other model kits I have will work for this project so, I can't use them as a mold master for resin castings of the cylinders.
Does anyone know where I could get my hands on a junk (no cost, really cheap) R4360 cylinder so I could take measurements at my leisure? Better than that would be a 3D CAD file. There is an outfit that can make the master from the CAD file pretty cheaply. As I said, this is a crazy idea and I may not live long enough to pull it off but, it's taking a long time to bring everything together so, maybe, I can. Any help would be appreciated.

Thanks, Tim. There is a cutaway at the Chanute Museum in Rantoul, Illinois, too. I've taken some pictures of it and could do some measuring there if I have to. If you've never been to the museum you should go. One of the guys asked me about why I wanted so many pictures of the R4360 and before it was all over, he had taken be in the back and let me help on the P-51H restoration for a while, took me up in the Connie
(EC-121?), and showed me other cool stuff. I used to hang out up there when I was a kid and they had a B-36 on display. Ah, memories.

Try getting in touch with this group, they have an ever increasing amount of information:

Thanks a lot but, I have already talked to Graham White from there and I have his book on the R4360.
There are also some guys in Australia who are working on a scale R4360 that will run so, all their drawings are geared to their engine. They already have an R2800 and some others. I lost the information when my computer died on Father's Day so I'll have to find them again.
I guess I'll just pack a cooler of water and sandwiches and head to Chanute with my measuring devices. I could stop and see my folks on the way, too. They always like it when I just show up.
Thanks again.
