Looking at your block cross-section between the cylinders - is there definitely room for those head fasteners - the walls must be getting very thin?Simon.
I need 50 modified M1.6 allen screws but I've done all those and tapped the holes. Also just over 50 12BA cheeseheads. I've modified about half of them so far, I'm doing it as I need them.
I love the fact that you're building this with a Sherline. (I've got both a Sherline and a Unimat.)The fact that you're mostly building it out of steel is even more impressive. Why did you chose to use steel for the block and heads over something easier to machine like aluminum or brass?Don
Really nice work, Steve!I don't have a lot of experience with IC engines. So can you help me understand the difference between the Left, Right and Universal heads? All three look the same to me.Thanks,Kim

All three look the same to me.There is no real difference between left and right - the holes are effectively symmetrical. I've just given an extra mil of metal at the front end of each to accommodate cam gears. The universal has an extra mil at both ends.

Nice work Steve Kim - as your question was a bit of two questions in one (one about this particular and one general) ->Generally all V-engines have a mirrored parts, though the placement is usually a con-rod offset between the halves (there are exceptions, with 'Fork 'n' Knife Rods').Inlets and Exhausts have different pressure and temperature -> bigger diameter on the Inlet ducts and valves and smaller diameter on the exhaust side -> optimum power, etc.
I am hoping to use brass liners in the cylinders.
A great piece of work! I haven't read through the whole process to see if you have already covered this question, but why 1/12th scale?
