I use to build the BIGGER version of those. NO! not the coffee table, but the REAL deal! The biggest Radial engine I have built is a Pratt R-2800 CB-16. But I have workedon a R3350. Most of the WWII vintage aircraft engines would require a HUGE living room to display it in.
I also use to build these VERY rare engines: Anyone know what it is?Attachments

WINNER! But, actually the engines I built were both the 58's and 74's. The 74's had the two stage supercharger on them (two 13.4" impellers, in series). They were in the Firefly fighter, and the model 58's were used in the Shackelton bombers.
Here's interesting reading for those interested in the inner workings of a Rolls-Royce Griffon engine, one of the best engines EVER developed. Griffon Engine Remember, that this engine (along with the smaller Merlin) were developed in the late 1930s. The piston alloy used in the Merlins and Griffons still can't be beat today. Even the crankshafts and rods are unbeatable today! I know, we use to kick the rods outta our engines, but when you turn the engine to 4,200 rpm with 60-65 psi boost, your GONNA have problems (especially when the propeller is spinning in and out of the water at over 12,000 rpm)
Here's one of the engines I use to work on. This engine is a model 58 with a model 74 supercharger on it. The prop shaft is contra-rotating for aircraft use. You can even see the adaptor plate on the back of the engine to run a PR-100 carb. (Can you say HUUUUUGE!!) The PR-100 was used on the R-4360 radial.Attachments

That is some awesome info!
Do you still tinker around with those engines, or tinker with planes?
Sounds like you really enjoyed playing around with em.
I will have to click the link and check it out.

The last time I was involved in Unlimited Hydroplane racing (220 mph flying boats) was I was asked to design and build a turbocharged Rolls Griffon with EFI. After hours of research and lots of phone calls with Jim McFarland, Corky Bell, Turbonetics, and a host of EFI companies, We came up with enough parts and brain power to build a 7,200 hp @3,200 RPM Rolls Royce Griffon on gasoline and NO N20. We would still use the nitrous to get it out of the corner for sure. On the "Bud" boat we would go through 150 lbs of "NAWZ" (as the kids today say) in about 4 minutes. (along with 60+ gallons of 115/145 AV gas with MMT added to it, and 20+ gallons of "ADI" water methanol)
But after alot of time and brain drain, the funding fell through and they decided to go Lycoming T-55 L7 turbine. Those turbine boats are fast around the corners, but piston boats really have the HP advantage for the staights. Nothing like 2,240 Cubic inches SCREAMING in your ears! Back in 1985 one of the drivers (who drove a turbine boat) came to us and was complaining that he wanted to crawl into the bottom of his boat to get away from "That DAMN Griffon screaming into my ears.......It REALLY HURTS! "
I also helped a team with the development of their 2,500 CID Packard V-12. They were having rod bearing issues and just couldn't keep the rods in it at 3800-4000 rpm.
My airplane work has been mainly Radial engines, turbine engines and BIG commercial planes. I have spent many hours restoring the first Boeing commercial transport, the 247-D, for the Museum of Flight, but that was many years ago and now my kids/racing/engine building takes up my free time.
