Really enjoyed looking at your build. It looks great. I have to ask where did you get all of your laser cut clamping hardware and right angle rib tools etc. Those are great and I apologize if this has been asked already. Thanks

I probably have, but they come from Retro R/C (http://retrorc.us.com) Mark Freelander makes them.

The crankcase is coming along. I got it sealed, the three cylinder port cut and fitted for the cylinders and the beginnings of the propeller support made. The next step is to fill and seal the propeller support (and its triangular bosses), Once this complete I can add the bosses to the crankcase and start panting and detailing the engine sub assemblies.

My next problem is how to build the exhausts and the valve trains. The kit includes 3 laser cut rocker arms for the valve train but I still need rocker arm supports, push rods, valves and valve springs. All of these are extremely visible on this enginend it will look naked without them.

In the meantime, her are a couple of photos of the crankcase with the cylinders in the new homes.

I'd suggest sllt brass tube for the rocker mounts, wire with slit tube ends for the pushrods and sections of spring from those throw-away lighters for the valve springs with a pin and small washer for the valve stems.

Just as an aside, I've found automotive filler/primer to be good for hiding the wood grain on cylinders, crakcases and cowls. Spray on a couple of coats, sand smooth, spray again and repeat until smooth and grain free. Any weight it adds is in just the right place.

I second the primer thing. When you go to the auto store get the one labeled "filling" primer, not "etching" primer. I have seen a can that was both etching and a filler. The one I bought just labeled etching was pretty thin stuff.

Have fun with the fiddly bits.

Well, I had a little time to work on the crankcase. I've used some 3/32" polystyrene tube to make some "bosses" that could hold the crankcase together. Once painted, the look ok. I have some #1 hex head screws coming to close up the front of the tubes.

The cylinders are next.
