My friend and I just completed building three of the PM Research Inc. kit of the 1/4 scale model Red Wing water cooled hit 'n miss engine. One for each of us and an additional one for me to sell. This cast iron kit was purchased from PM Research, Inc. The flywheels are 8 3/8" dia. 1 1/4" bore and 2" stroke, water cooled and governor controlled. Starts easily and runs well see the included video.
Because I've had many requests in the past for engine construction photos I decided to take many photos of this engine project and put together a CD that could be later sold to other builders both amateur and professional. That evolved into quite a project. Early on I decided to add text captions on some of the photos to further clarify an operation. I ended up spending a lot of fun time putting together the CD resulting in what I feel is great tool for builders of this Red Wing engine or any other engine, hit 'n miss or other. Among other things I got much better at using Photoshop.
This engine is FOR SALE complete as pictured including the walnut base, walnut glass protective
cover, "Buzz Box" ignition system with charger and rechargeable gel cell 6V battery. See the video
of the engine running. Contact me if you are interested.
The Walnut mounting base measures 13 1/4" x 24 3/8"
The engine has 8 3/8" dia. flywheels, 1 1/4" bore and 2" stroke.
For this engine I made a ignition system "Buzz Box" complete with Ford model T points, a coil, a rechargeable gel-cell battery and wall plug-in charger. Makes for a neat, compact package. I plan on producing Buzz Boxes to sell. Contact me if interested.
All of my engines, including this Red Wing run on regular gas pump gasoline.
This could be called a carburator but Red Wing and Lunkenheimer, the maker of the full size originals, call it a fuel mixer. I understand that in its day it was considered the best and it was rather expensive.
The original full size engines used an igniter whereas many were converted to a spark plug as is used in this model.
I made a tubular brass stack rather than the smaller muffler provided with the kit. I like the sound!
I like the idea of a removable glass cover for keeping the engine clean while on display in the home or office.
