V-twin engine from scratch - yet another interpretation of how (not) to build a

Today, I took the cam housing apart, disassembled it, and drilled oiling holes to the top of it. That was just one of those things, that I had forgot to do.

At this stage, the engine has an 'open column' crankcase, so no shared oil splashing lubrication available for cams.

But if(when) I manage to get the engine to run, then I'll make an aluminum or brass cover for crankcase, enabling the use of an oil sump.

Anyways, after I assembled the engine, it felt quite stiff again, so I gave it about half an hour spin on the lathe, with plenty of wd-40.

There is still some work to be done though, to get it to testing condition, such as the base, where to attach it, and valve adjustments.

Mad jack, it's good to hear, that you have guides to follow on that ceramics-thing :thumbup:.

Mad jack, it's good to hear, that you have guides to follow on that ceramics-thing :thumbup:. I tell you, I don't much like the idea of regular sized plugs in a model engine, or model plugs that don't work but for a short time. If we can make models of the engines, we ought to be able to make working models of the plugs. If I don't get success on the plugs soon enough, there's a guy named Bob Shores who makes model engines and pieces and parts for them, and he has proper model plugs as well as other ignition accessories, he's got a web site which should be easily found, although I don't know it offhand. Don't ever say "if" about an engine, they always get to run, even if you have to make every single part all over again, it's always "when I get this engine to run", got to think positive. Of course sometimes in the middle of things, an engine can turn majically into a flying projectile weapon, and kill a window, or some offensive weeds right outside the shop. Then it has become an engine of destruction, but still an engine, and it did "go". :lol: mad jack

Sorveltaja and Jack, if you fellows are having trouble making spark plugs, have a look at a gent who knows how it's done. George Britnell is a member here, and has been nice enough to share his considerable experience with us. His plugs look good, and as evidenced by his many running engines, they work well, too.

The "How To" post is at the following link:

Happy pluggin'.

Mad jack, take your time, if you intend to try the ceramics. No deadlines here :thumbup:.

What comes to the engine project, it will unfortunately be interrupted for some time.

At the moment, I have some serious official matters to take care of, so not much progress on the project.

But I'll be back as soon as possible.

Hope all is OK. Looking forward to seeing this go on.
