Reviewing the ML Midge from MotorBoys

[jimbo7636]

Ive carefully read the build instructions at the modelenginenews site about how to machine the crankcase. In that text I saw there were some small metric to imperial discrepancies between the text and the drawing. Also some instances where the dimension scheme on the print did not follow the machining procedure. So I created my own model/drawing of the crankcase. I will continue to review and layout my own version to make sure i avoid what interferences I can prior to actually machining the engine. Any input?

I built one years ago to the plans. It was not particularly hard and runs well. I do not recall any problems with the drawings. I often swap and mix imperial and metric threads in my models to get best fit, scale, and convenience. I forget whether I did that on Midge.
