45CC Wall Wizard
Jo:
The Wall Wizard is a 45CC Horizontally opposed twin engine that was designed by Elmer A Wall in 1933, in Chicago, Illinois. Lets be honest I would not call it pretty ::) But Elmer claimed that "that the engine was so well balanced that it would "start on the first turn-over if machined properly and that it would idle down to a tick or roar full speed when the throttle is opened." :noidea: ... So I am hopeful I might be able to make a running engine :)
Most recently these castings sets could be purchased from Coles in the States but no longer. My particular set was extracted purchased from Mike Paitence, Worthing UK who is a fellow model engine casting hoarder enthusiast. Sadly during Mike's fondling sessions the flywheel was lost from the set :ShakeHead: and if it ever had a base we will never know :disappointed:
Initial casting fondling has shown that the crankcase machining is going to need to have to be a compromise :facepalm2:

A visit to my Supplier allowed me to have a dig through his scrap bin before the scrappie took it away and I came up with three pieces of bronze to make the flywheel out of. Ok yes I know that I am not fond of shiny bronze bits on engines :hellno: but decided that it might make the engine a little prettier and bronze silver solders together ok.
Stick the two smaller bits together to provide the required width, make some spokes and turn up the ring. then follow on with a bit of fettling to make the pieces more rounded in appearance before silver soldering together. Turn the rim true by holding on the boss.
The flywheel is now ready to have its taper cut, which will be done at the same time as cutting the taper on the crankshaft ;)

P.S. I roughed out the crankshaft last autumn when I was at home recovering :embarassed:

I’m really going to be watching this one Jo; as I have a set of castings that have been aging for a couple of years. I kinda thought about a 12-14” prop in place of the flywheel :thinking:.

Hi Big E :)
Pleased at least one person is interested in this engine :ThumbsUp: I was getting worried no one was interested after I suggested this is not a pretty engine ::)

It would need a big one something around a 24"+ Prop :paranoia:

Well a Victorian Beam engine it ain't, but still quite an attractive engine in its own right Jo. Hmmmmm….I am thinking Eric is holding out on us as to what he may have in his collection. May have to send Roy D. Mercer over there to Tennessee to check things out. (Big E will understand this) Anyway, carry on, I am sure a lot of us will be watching ;)
