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

Eric, it will be something like 60 degrees v, although I've read that 90 degrees would have less vibrations.

Here is the first candidate for crankshaft:

It gives a stroke of about 15mm(~0.59") and bore will be smaller than that.

Axle has 4mm(0.157") diameter.

Hmm.. almost right. That's just how I cut the bigger stuff. First cross-drilling, then some delicate butchering to part the stuff.
~Where art thou, my beloved chainsaw~, as Hamlet would say.

But to the point. Aluminum block, that'll form the crankcase, is almost prepared for the lathe, and then for milling operations. Good chance to test my angle milling skills.

I vote for over head pushrod valves :)

It's been bit quiet, because my lathe's belt snapped. It's now fixed, so back to project.

It seems that my lathe is seriously underpowered, what comes to that 50x50mm alu piece. Machining it is even more tedious, than I expected :wack:.

I looked an alternative for solid crankcase, and found out, that the Hoglet type would be much easier to achieve. Being scratch built part, it suits the spirit of this project :med:.

Two small bars are 20mm(0.787") SS 2172, that is available nearby store :thumbup:. It machines quite well, so I use them for cylinder liners.

Krown Kustoms:
Very nice so far.
I will keep up with this one:)
