The RV-2 is a four cylinder opposed style engine with gear driven valves and timing. The design is inspired by the internal combustion engines that power so many of today’s general aviation aircraft (and VW's!). The pistons are 3/8" with a 1/2" stroke driving a one piece aluminum crankshaft that rides in miniature ball bearings. The "RV" designation is for "rotating valve". The unique valve design incorporates a pinion gear on the crankshaft which times a one piece rotating valve. This polished brass and aluminum engine would make a great display piece for any aviation enthusiast or lover of mechanical things. The engine is pictured with 6" propeller but can also be fitted with a flywheel.

Building it-

This is a perfect intermediate level project for the home machinist.  It involves 61 fasteners and has 43 parts that you will have to make. The designs are CAD drawn with clear easy to read dimensions.  They have an individual drawing of each part and 3-D views of all the more complex pieces. All dimensions are clearly shown and suggestions for material are given for each part.  Please note that these are technical drawings not machining how-to instructions.  There are often many viable approaches to making a part.  That challenge is left up to you.  You will need access to a lathe and a z axis or a milling machine to build this design. A rotary table or dividing head will be necessary if you want to cut your own gears. Due to the difficulty and expense of obtaining gear cutters, we also offer pre-cut gears for this engine (see our ebay store under accessories). 

We also offer a kit which includes these drawings as well as all the hardware and metals you need to to build a complete running engine.  See our Ebay store under Steam Engine Kits for the kit.
