About 2007, a friend gave me a box of old kits, one of which was
this Pratt&Whitney Wasp Junior engine by Williams Bros. It
looked like it might be a challenge to build but by carefully
following the instruction book, it proved to be a fun project. |

|
Each cylinder was a small kit in itself with two halves of the
barrels and rocker heads |
The crankcase, gear box case and induction manifold along with the
cylinder retainer rigs |
The carburetor and magnetos built up next |
|
 |
 |
 |
|
|
The rear case with all of the accessories came next |
Test fitting the propeller hub and cylinders |
The rear case assembled and ready for paint and small bits |
|
 |
 |

Some of the small black plumbing pieces added |
Small bits added to the cylinders |
Prop hub glued in place. |

Spark plugs..all 18 ..painted |
Rear case with all the bits'n pieces painted |
Then glued in place along with the induction tubes |

 |
 |
|
|
Push rod tubes added and the ignition wiring in place |
The wiring is #32 electrical wirie, exhaust pipes added and painted
with Model Master Burnt Metal |
Each wire is of a different length, plug boots added to the wire and
