Ah, ok. I mis interpreted that.How do I send you the 40USD? Can I do that via PayPal?

Steve- Thinking about this a bit more - If the pics are prgrammed then I would be very interested, otherwise I have no hope of programming them if they need that. I note others are interested so I will let this one go, this is purely based on not being able to program the pics. I will keep...

Hi Steve, That would be great, if you find one I will pay all expenses (I am in the UK) For postage and some beer vouchers as well. The use of an automotive battery was my intended route and looking at the boards, they look like a row of mosfets or 220 cased bipolars with drivers that provide...

Hi Steve, Do you have the circuit diagram for the 4 channel glow plug driver? I have a 4 cylinder engine nearing completion and need to figure out how to supply all 4 plugs. I guess you have given these away by now. Many thanks Steve

Hi all, I have had a reply from Volker Jung, see below, Hello, sorry, we have change the followed drawings. See the pdf`s. Mit freundlichen Grüssen Dipl.-Ing. Volker Jung The pdf files are attached for info. Looks like we were right to follow this one up, the cam sequence was not right...

Hi, The prop has arrived and I can confirm it operates in the CCW direction as viewed from the front. The reference taken from the 2D drawings does not indicate the orientation of the two centre lobes, this information can only be obtained from the 3D view which was where the issue was...

I used a 50 x 180mm piece of Meehanite cast iron to create the liners and rings from. The bore was bored to 34.5mm and honed the rest of the way to 35mm. I used the expanding 3 legged type of honing tool, they took a long time to do and I wore three sets out during the process. The Pistons were...

The carbs are manufactured by ASP and they are the series 3 type - chosen because they are quite cheap. No idea how they perform yet. There are some details on www.justengines.co.uk

Hi, I am a bit late in posting this engine - a twin cylinder in-line 62cc engine design from WWW.cad-modelltechnik-jung.de The plans are quite easy to follow and I have made just about all of the parts as can be seen from the picture. I had not taken pictures of the various stages of machining...

I enjoyed making this engine, and thinking of the boxer next myself -toying with the 4 cylinder boxer which looks really good - maybe just the twin like yours. I hope that the cam is OK now you have made yours, I thought that the rule of thumb where the exhaust leads the intake cam a great point...

Hi Petertha, I did look at the suggestion that the carbs would fit over the other side, and you are right, they would interfere with the push rods and rocker assemblies. I sent an email this morning to 'Jung' and surprisingly got a reply within a couple of hours which was very good, they are on...

Thanks for the help, this really helps. Some good advice too, swapping the intake and exhaust positions - I never thought of that. Petertha, Haha - you tracked the engine down - great stuff. There is no idler, the drive is via a toothed belt (usual 2 to 1 ratio) thus the crank and camshaft turn...

I am building a twin in-line engine and having machined the cam shaft blank I studied the profiles before progressing further. To my eye, the drawing is wrong. The shaft will rotate CCW looking rearwards from the front and the lobes themselves, positioned at 0 - 90 - 270 and 0 degrees, looks...

Good work Brian, the work you have produced is spot on to get the clearance right between the cam and the lifters. I have built a similar overhead version and purposely left a bit of extra material on the lifters so that once the cam assembly is attached, small adjustments can be made to the...

Hi Brian, I have the same cross slide assembly as yours and have often wondered whether the slide could be put on facing the other way thus having the gib screws on the chuck side along with the gib strip. Do you think that could be possible? This way would allow the attachment of the DRO...
