Lou, that's a very nice engine. On a test- stand too. Neat.

Test stand from 1/48 scale HAWK T-33A kit. It works but a bit to low to spin the prop.

Thank you Ken. For now it be a stand alone model until I decide which airframe to build. I saw that the DHC-3 used this engine. ??

Lou,
The P-26A uses that engine as well.

It looks very effective Lou,once you paint it then everything pulls together and will look like metal,well done.

Per Lou's request here are photos of a 1:72 scale Napier Lion V engine for a Fairey IIID being completed as part of the Long Distance Flights cook-up.

Per Cliff Strachan's lead, I decided the best way to build such a tiny engine was at the end of a 1/4" square pine stick which formed the crankcase.  2mm dowel was used to make the twelve cylinders and these were topped off with basswood cylinder heads and intake manifolds.  The cam drive shafts are pins at the rear of the cylinder banks.  Valve covers are filed from aluminum finished with emery cloth and metal polish.  Intake pipes are from solder.  Exhaust stacks filed from 1mm paper clip wire.   Thirty eight parts total of which eighteen are metal.

The engine sitting on your finger really give the feel for the size and complexity of making such and engine. You must be congratulated on such an outstanding job.
