grabcad

This is a simplified radial engine using a diskvalve driven by an offset pin in the hub of thecrank mechanism. It is interesting to build andrun; and with three impulses per revolution, ithas quite a bit of power. The optional BearingBushing is "Oilite." Use any material you mayhave in your odds-and-ends department as thekind 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 extraword will be mentioned.
