Green G30 Single Cylinder Sleeve Valve Engine

[Vixen]

Have any of you heard of the Green G30 single cylinder sleeve valve engine? It was designed by D F Green way back in 1988
There was a short build article published in HMEM  earlier this year http://www.homemodelenginemachinist.com/showthread.php?t=24084.
 I have attached one of the photos showing all of the finished components.

I have a complete, untouched kit: Drawings, instructions, crankcase casting all materials and fixtures which I realise I will never get round to starting in my lifetime. Is anyone interested in taking it on? I am open to offers.

Quick Jo castings!!!

Hi Mike, I don't have one of those 

Are you coming to the model engine swop meeting on Sunday? Would you like to bring it with you? (Or we could drop in on the way back about lunchtime )

Jo

Hello Jo
Where and when is this model engine swap meeting on Sunday.
Sounds like it could be a nice day out for me

Looking forward to seeing you. If you could bring the castings with you 

Jo

P.S. We won't tell Jason, he doesn't like building engines out of castings any more he thinks they are not challenging enough 

[Vixen]

OK But you had better have a wheelbarrow full of cash. Ha ha

Mike

Looks more like a mechanic's kit than a casting kit.  Haven't seen the plans or what the finished engine looks like but those don't look like raw castings

If you get no takers I'll buy it.

Bill, the photo is from the build thread.

[b.lindsey]

Ah, OK. Thanks Greg.

Bill

[Jo]

I've been looking at the drawings and fondling a set of castings for one of these engines today 

It does look interesting  .

Jo

[dieselpilot]

I'd be happy with a set of prints.

Hi Mike (Vixen) - did you manage to 'offload' your Green G30 kit of drawings, castings, instructions etc.?  I know it's a while ago since you originally posted, but I have only just noticed this thread.

I ask as I have a (I presume) set of original imperial drawings of the engine and am starting to machine the engine up from 'stock' as I don't have any castings or fittings, just the drawings.  It will be/is a bit of a challenge as it's a first engine build for me, so quite a learning curve; set ups, work holding, and even order of machining each part are all up for serious bouts of 'ascertaining' before, and as, I progress.  I am already on my second crankcase and front bearing extension, crankcase machined out of a aluminium cube - the first one suffered a seizure of one of the threads when the front bearing extension was tried and eventually destroyed to get it out, sorted that and nearly finished the crankcase but then tried to be a clever dick and pretty the nearly finished article only to louse it up completely instead. So, so far, have made the cylinder barrel, cylinder head, front bearing extension and internal distance piece, and the timing cover plus nearly finished the crankcase, having done all the internals and now just sorting the outside.  Progress is very slow but, lack of experience and trying not to louse things up are playing their part!

Although I do have a set of redrawn metric plans I am making my engine using the imperial plans.  I can work in either units but prefer working in 'thous' to the foreign bits of a mm, a 'thou' mean something - I was trained/brought up using 'thou', lb/sq.in, degrees F, feet and inches, lbs and ounces etc so they still are meaningful and I can more readily visualise them, whereas although happy to work in mm and metres and kg/sq.cm and degrees C if I must, and there are times when mm and metres are jolly useful to use, in reality they mean very little to my little grey cells!

Chris

PS Now having read the thread a bit more carefully I see that Jo has all the bits!

[b.lindsey]

Chris, why not start a build log. This is not an engine i am familiar with si would enjoy seeing more about it.

Bill

[Jo]

Hi Chris, Mike still has the castings and materials for his engine

As you can see my supplier came up with the basic crankcase and was threatening to have some cast but don't hold your breath  .

Jo

[Vixen]

Hello Chris,

As Jo said, I still have a complete un-started kit for the Green G30 Single Cylinder Sleeve Valve engine.

The kit consists of a set of drawings (dimensions in inches), instructions, all the aluminium, steel and cast iron stock materials required. There is also material for two machining jigs, gear wheels, bearings and a ready made carburetor. The kit has been re boxed, the complete kit weighs several kilos.

I am open to offers, so if you are interested send me a PM rather than the open forum.

Mike

Jo - I thought that your fondling of a set of castings meant that you were very much on the case and had scooped the kit, sorry.

Bill - I might well do a build log, I have thought about it, but I will get further down the track first.  My work is so slow everyone will loose interest if I start a log now!  But it is an interesting engine and different to the rocker operated valves engines.

Mike - I was just interested if you had disposed of the kit and, following on from that, wether anyone else was building the engine.  But I will pm you anyway.

They all think that, but I do have (some) self control

I have lots of self control myself, Jo.................I can resist anything but "temptation"!

I remain hopeful 

Jo

[Jasonb]

I remain hopeful....................

Jo

....................Of getting a set of castings cheaper from your usual supplier than from Mike

[Jo]

  I know it is difficult to believe but there are more important things in life than castings that one remains hopeful for.

Jo

[Jo]

Another set of castings has been acquired for my Surus' casting collection 

 

Jo

[Vixen]

Good for you. It will make into an interesting engine

Mike 😁😁

[Jo]

Thanks Mike, Did you notice how it took two years to acquire these castings after my supplier wafted them under my nose 

In the mean time can you guess how many engines he has built  I'll give you a clue I have brought more sets of castings from him than he has built and he has brought more sets than he has built as well.

Jo

[Vixen]

Ha ha Nothing ever changes. Thought I recognised the photo

Mike

[Vixen]

Jason wants to know how many engines have YOU built in that time?

Mike

[Jasonb]

I'll give you a clue I have brought more sets of castings from him than he has built
Jo

So the answer could be anything upto 999 To be fair to Eric there are a lot more parts to complete on that Loco he is doing than a 5min job on an aero engine

Now, Now Mike, you know me and Jo have a different idea of what "built" means

[b.lindsey]

So does one casting (excluding the machined gears) comprise a set?  Or is there more we aren't seeing ? 

Bill

[Jasonb]

Bill, have a look at the photo Mike posted at the start of this thread, some people really only needs the one casting others would not even need that.

[b.lindsey]

Jason, yes, though i was referring to the photo Jo posted above

I have acquired 17 new sets of castings in the last two years         Correction I have acquired 15 sets of castings in the last two years

Eric has a pair of frames (That I think were laser cut) bolted onto the buffer beams, horn blocks (not sure if they are riveted on  ) Axle boxes, Axles, set of eccentrics & sheaves and a water pump. Cylinders are underway, as are wheels. So it is nearly at the stage that stage he sold the other one he started last time when he realised it was too heavy for him ....

Bill

Yes one casting is the full set. Originally it came with the bar stock and bearings as a kit which is the one Mike has. But I have a few bits of bar stock lying around  the important bit is that over width gear.

Good going, considering your time off with the

Locum Doc yesterday told me a few truths about his consequences: it will probably be 2 years before I stop having problems cause by HIM    And as for the expensive Elephant extraction oil that needs to be rubbed on twice a day

Why is it that your own Doc tells you only half the truth
