      Very nice, Sid! The valve lifters are a cool design. I'd be interested to see what they are like inside. Never seen any like that, before.

        Beautiful work as always Sid. I like your attention to detail, and eye for the aesthetics. Curves where there needs to be curves, and sharp corners where they're needed too. It's the little things like that your models seem to address. The black/gold colour combo which you employ a lot has always been one of my favourites also.

          Outstanding work, Sid.

          As Dan says above, the level of detail and aesthetics is outstanding.
          Every part looks like it belongs exactly where it is, and all flow into each other.
          Marks of superior design and execution.

          If I get a vote... I like the colors as is, clearcoat only.

              Tool Guy- Those are all fake! The valving is all done in the rear rotary valve.
              To be clear, this my version (highly modified) of Rudy Kouhoupt's original design.

              I added features like the push rods and rocker boxes. I redesigned the cases a lot. I tried to make it "look" like the real thing.

                Joe- it's got to be an odd number of cylinders for a radial!
                I used to know why, but right now I don't remember???

                Unless your talking about a Merlin (V12).

                That would be quite a challenge right now, but I've seen a few at shows.

                    Those are extremely nice looking!

                    You excel at what I am not good at.... getting a good surface finish.

                      Thanks JT. I have some good equipment.
                      That can make a difference. But still, the best equipment is not a guarantee of outcome.

                        Engine looks awesome. I never realized about the odd number of cylinders, I had to look it up. From what I saw, main reason is so it fires consistent every other cylinder for vibrations.

                        I think there are some double row engines that do technically give you even number of cylinders.

                        Either way, nice job.

                          I think the odd number of cylinders has to do with the firing order.
                          I'm I'm pretty sure the ones I saw it Wright Patterson we're 12's
                          I think they were Pratt's. There were double row ones too.

                            OX- Your right! I was thinking two dimensionally!
                            Double and triple row and more! 18 and 36 cylinders.

                            Sorry Joe, I stand corrected!

                                That would probably be best to do a video.
