Some running video today

 

[minh-thanh]

It's a really small engine
Beautiful, runs well
Congratulations !

 

[Olli-Matti]

Thanks minh-thanh, it runs nicely but is a bit of a handful to get going just by flicking

 

[rklopp]

Nice job! That puts you in rare company. Not a lot of folks have built those successfully. Those are known to be very difficult to start.

 

[Gary C]

Congratulations. Excellent work and it runs beautifully.

 

[Peter Twissell]

It makes my Whittle V8 look huge!

 

[Olli-Matti]

It has a tendency to do so to almost everything!

amazing work Olli. What a beautiful build. Great runner too. You have me inspired to make one too.

Hey Olli,

I'm venturing back into my workshop after a few months off. I want to build a pair of these.

I sourced the plans from ME Nov 1992 and am starting to play around in CAD.

Quick one for you. Were there any 'gotchas' in the plans? I found a thread that said there is an error on the angle to drill the intake port in the crankshaft (43 vs 47.2deg). I know that one is really not that critical.

Your engine runs great!! Did you pretty much follow the plans pretty much to the letter?

Thanks,
Patrick

Hello Patrick!

I don’t actually recall anything being off in the actual plans. I did build pretty much as per plans. The text and methods described in the original build article was something I did not follow in many places. Partly because of the language barrier and me not quite understanding all the details but also as I opted to use a milling machine in many places whereas in the article most is done with a lathe.

Hey Oli, nice to hear from you. Looking forward to make some swarf. If my result is anywhere as nice as your pair of beautiful engines I will be very happy indeed!

I'm busily modelling things up on CAD at the moment. One thing not clear from the plans is the radial positioning of the ports in the cylinder. Did you have the 3 transfer and exhaust ports aligned or staggered? i.e were both at 0, 120, 240 degrees? or did you to 0,120,240 and 60, 180, 300? Hope the question makes sense. Your engines run great so you obviously have it right.

Also, that micro tooling looks great! Can i ask where you purchased it from?

Thanks,
Patrick

On the cylinder, the transfer ports should be centered on the posts between the exhaust ports. Are you asking about whether the threads need to be "timed" with the crankcase? I don't think it matters whether the cylinder transfer ports line up with the crankcase transfer passages due to the annular passage at the thread relief below the cylinder flange.

Hi Patrick,

I did three ports separated evenly as on the plan. 0,120 and 240 degrees. The front one being in the middle of the engine center line. I have thought about the port alignment aswell and tend to think that the alignment doesn’t really matter as it really is not referred to in the article at all. I did try to make my threads so that the ports would align though. And succeeded with that pretty ok. The ports were nicely aligned at first but after some adjustments (there were plenty when making them run!) the cylinders tend to thread just a bit over so that the perfect port alignment is gone but close. Seems to work fine like that atleast.

Edit. The micro tooling is phorn tooling. I have got those mostly from ebay. I have a couple of suitable toolholders and like them very much.
