The Beginning of another I. C. Engine,

[DavidLloyd2]

------------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
Two Days workshop time I have two side plates ,

To be continued.

[Cogsy]

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

 

[DavidLloyd2]

N Z is metric and all the stuff I am buying is in metric
Drawing for the side plates call for .375 material I am buying and using 10mm,

NSK Bearing I got are mm: 6001DDUCM 1605 NS7SI 12mm ID

Nut and Bolts call for imperial I will be using mm

[Brian Rupnow]

Great stuff, David. I will be following closely.---Brian

Looking good Dave - James (Joco) and I will have to pop out and have a cuppa to see the progress

Cheers

Bruce

 

[Herbiev]

Looking good David. I'll be following your build too

 

[Brian Rupnow]

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,

[MariusTitulescu]

Looking great, man! Keep it up!

 

[DavidLloyd2]

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,

Beautiful work David. I find it absolutely thrilling when someone else builds one of my engines and documents it.---Brian Rupnow

Dave

Nice!! You will have to bring it along on Wednesday

[DavidLloyd2]

Some Progress being made in the last two weeks
I have never made a Built up crankshaft and con rod this way

Thanks to Brian's excellent instructions on the crankshaft drawing all went together good,

DavidLloyd

 

[Brian Rupnow]

Great work. I am following with great anticipation.---Brian

 

[Brian Rupnow]

David--What happened to your build? I tune in every day looking for progress, but nothing is happening. I hope all is well.---Brian

 

[DavidLloyd2]

Brian
Making cams is not one of my favorite things to make Hopefully by the end of the day I will have two cams that I will be satisfied with and move on to the flywheels,

[Brian Rupnow]

Thank you David. Cams are not one of my favourite things to build either.---Brian

 

[DavidLloyd2]

The Month of August in New Zealand being Cold Time in the workshop is limited
But some progress.
Brian after no response from trying to locate a water jet company in Wellington I have committed to do the flywheels myself
Parts to add to the Rockerblock,

DavidLloyd

 

[Brian Rupnow]

Great stuff, David. Thank you so much for the pictures. I spent a lot of time and money on my water-jet cut flywheels, and although they are quite remarkable when setting still, you can't see how fancy they are when the engine is running anyways.---Brian

 

[DavidLloyd2]

First cuts



One flywheel one to go


Two flywheels and one starter hub



And a Flywheel puller,
