Radial Engine

This is a simplified radial engine using a disk valve driven by an offset pin in the hub of the crank mechanism. It is interesting to build and run; and with three impulses per revolution, it has quite a bit of power. The optional Bearing Bushing is "Oilite." Use any material you may have in your odds-and-ends department as the kind of material is not critical. The Base is detailed to show four anchor holes, a decision made after the engine was assembled. Since most of the parts involve common machin- ing practice, only the parts that need an extra word will be mentioned.
