As a practice before making the 4 cylinder, 4 stroke engine for the mini caterham, I have decided to make some simpler engines.
The first engine I have chosen to make the Boll Aero 18. It’s a 1.8cc diesel engine with a 1/2 bore and 0.550″ stroke. I intend to make this as a practice for making cylinder liners, pistons and shafts and achieving the correct fits / tolerance.
If you would also like to make this engine the drawings are available here: http://modelenginenews.org/plans/BollAero18.pdf
My most recent YouTube series see’s me making a manual Shaper. I have always looked at shapes and wished I had the space for one (they are a large machine). They are however very useful for cutting internal key ways.
This Shaper however is very compact and will prove to be useful when I need to cut internal key ways and splines for the various gears and hubs on the mini Caterham project.
I now have two videos already uploaded on YouTube showing the making of the shaper body, ram and lever.
Once the build is complete and the design is debugged I will be making the drawings available to download on this website for a small fee. Keep checking back here for or on my YouTube channel for updates!
