Default The Beginning of another I. C. Engine,

------------After Building Brian Rupnows vertical I. C. engine and being please with that engine I decided to have a go at Brian's Rockerblock I. c. engine.
So I started on the two side plates

Looking good. I'll be following along. Are you building it in metric (I ask because of the NSK bearing)?

Strangely enough, I designed it for metric bearings because I had a pair of sealed 12 mm bearings I had saved from something I tore apart. However, that was the only really metric part. Of course the crankshaft had to be partly metric to suit the bearings, and the bore of the small gear, ignition cam, and flywheels had to be metric to match the crankshaft. I can work in metric, but I'm not really comfortable with it. I was in my mid to late 20's when some fool decreed that Canada would become a metric country. I had to work in metric after that for 10 or 15 years, but Canada slowly transitioned into a permanent haze of semi metric/semi British Imperial (inches). I reverted back to the old system I learned 65 years ago in the public school system. Now that I design ****e mostly for fun, I don't do metric unless I really have to.---Brian

Good Day and Time for a up-date and some photos
I have completed the Rocker Post and the bolt down plate,

I will make the cylinder head end next to keep the frame together.

I do like the 4 jaw self centering chuck on a rotary table Ideal for quick setup for doing the radius on top of the Rocker post,

Default Up-Date

I spent most of my time working in my cold work-shop on the cylinder head end of the frame.
Three Excellent Drawings got me through that no problems.

Cylinder is made from cast iron and the Bolster- Tappet Guide is from bronze,
