The Beginning of another I. C. Engine,

[ShopShoe]

DavidLloyd,

That's looking very nice. Those flywheels are perfect to my eyes. This engine design is pleasing to look at and I'll be watching for more progress as you go.

Thank you Brian for the design.

Looks really good. I know that there is a world of work in those flywheels. Cheers, Brian

Not allot done this past week But I did get the brass water jacket and top for the water jacket plus the cylinder oil cup done

That big chunk of brass started as 3inch in diameter and transformed to its rectangle shape allot of work but its what I had in stock.

The water jacket top and cylinder oil cup are made from scrap leftover bronze bits,

Wow--that is just lovely!!! There are a lot of nail-biting set-ups in that brass water jacket, aren't there.--Brian

 

[DavidLloyd2]

Getting close to the end Six more small parts to make.

Two pushrods Two valve keepers Two pushrod pivot shafts and that will be it I hope,

Well done Dave

Thank you Bruce
Hopefully the next time you see it Will be running a bit better and have a new base and painted flywheels,

[Brian Rupnow]

Simply marvelous. That is the second Rockerblock engine in existence.--And it may run even better than mine!!---Brian

That's a great runner David. Great looking engine.

Lovely looking machine Dave

Thanks for sharing

Nice one Dave. Nearly as good as seeing it in the flesh

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

I am pretty cirtain that NSK supply bearings in both metric and imperial.
I'm afraid that i'm an old fart who still thinks in imperial and is too old to change.

I am pretty cirtain that NSK supply bearings in both metric and imperial.

I believe they may do a few oddities (like 6205/25.4, etc. and automotive specials) but I think the majority of their range in deep groove ball is primarily metric. They do make great bearings though. Even while working for SKF we privately conceded that NSK deep groove balls were the best quality to be had.

I mostly deal in metric myself, and convert most plan sets to metric sizes, mostly due to tool and fastener costs. Having said that, I can work in imperial but it gives me more trouble for scaling and measuring, etc. Metric is just easier...:hDe:

I was around at Dave's today while he did some fabrication work for the club track. After the obligitary cup of tea (we're both Brits) he showed me the engine, with the carb we'd both purchased from Hobby King.

The engine was cold, we'd been working together on the welding for 3 hours or so. Dave topped up the fuel, turned it over by had a few times to prime it, switched on the ignition, brought the flywheel round to the compression point and then spun the flywheel by hand and she started first flick.

I tell you this because Dave is planning to post a video of him doing it and I can vouch that it will be a genuine demonstration. Very impressive.

[DavidLloyd2]

I purchased a new carburetor from Hobby King and installed it on my Rockerblock I. C. Engine and it Ran first time with my noisy electric drill

Then I tried it Turning the flywheel by hand and it started right up.

So I have put a short video hand cranking the flywheels if anybody is interested,
