My first home made model engine The Boll Aero 1,8

[modelmotor]

Hallo Model Engine Friends

I have done another modification at my Boll Aero 1.8 model engine.
I made a new piece of screwthread at front of my Crankshaft and used for it an
adjustment Bolt M5 x 40 mm!
You can see the final results on te photos i send with this reply message.
I hope you like the final result.

many greetings from modelmotor-Gerard-The Netherlands-Europe.

G'day Modelmotor
After looking at the photo's of your crankshaft with the undercut section of the shaft adjacent to the intake port on the shaft I would be very interested to know how well your motor runs.
Because by machining away what looks to be, between .010" to .020" off the diameter of the shaft the seal between the shaft and the crankcase is now non existent, meaning the port can never truly open or close, so that the port in the shaft is always open and you will be loosing crankcase pressure all the time.
Also you would be better tapping the shaft in the lathe between the chuck and the tailstock for alignment.

Rob Jenkins, it's not intake port. Also to lubricate the bearing via canal from crankcase to bearing. The engine is a side port engine.

Fair enough my mistake. I obviously wasn't paying attention.

Hallo Model Engine Friends,

I have found several small issues which needed an update at my first made Boll Aero 1.8 cc.This engine built in 2008 without any knowledge about about home made model engines diserves a good tune up i think.
I made a photo collage from all the parts i renewed or made from new material.
I hope that you enjoy the photos as much as i did.

Hallo Model Engine Friends,
Still a few other parts are revised at the Boll Aero engine for example a good fit Contra Piston which moves with a hard click to above when the piston goes upwards with some fuel between.
There's also a better compression lever mounted made from a tiny piece of steel plate.I did some refinements at he back plate and propeller screw which now can be mounted complete with propellor and propdriver.
I hope you like the pictures again which maybe will be following up by another couple of pictures when some new ideas are comming inside my head.
