Looking good!

Wondering - was the intent of the rounded end of the casting that the rounded end of the part would be there? Another of those parts were just some bar stock might have been as easy or easier?

Great question Chris, but I am using the castings provided regardless. Once the build is done I will provide some feedback to the company on just these types of issues. There are several cases where bar stock would have been easier I agree. At the least, castings a bit closer to the shape of the final part would be good.

And the castings do save on having to buy a lot of different sizes of the bar stock. The castings look to be well done, not seeing bubbles/voids in them.

Nice work Bill!

If you are picky and want all the parts to look the same you need to use the castings, otherwise if made from bar stock they will not be correct.
I can see where in lots of cases (here and on other engines) it would be easier to just use bar stock, but at least using the castings all the parts will have the same look.

That is true Dave, so far its been all castings except for drill rod shafts. Even the parts specified to be made from bar stock I have used bronze rather than brass.

Very pretty little parts there Bill!
Interesting discussion on mixing casting & bar stock parts.  I'd never thought about that!

I got the second link made between yesterday and today and also the eccentric rods. The rods have been left intentionally long and unthreaded on the lower end for now until final assembly. These two sub assemblies are shown in the first two photos below. The  links were finished off by drilling the two oil holes in each (photo 3). Lastly for now, the drawer where I an keeping the finished parts so a family shot of sorts.

Thanks Don, Yeah, this one is pretty much ALL bronze except for the various rods which are drill rod. Have been trying to get a good finish on each as I go along.

Nice work on the Links, Bill.

You've got a nice collection of parts there.  When are you going to be ready to assemble them on the engine?

Kim, I need to get the base plate finished up first. Then the pedestal and cylinder after that. Still a ways to go before assembly begins.

Thanks guys. The best part is that since there will be no painting on this one, the parts in the drawer are finished!! Next up will be the bearing caps. I was looking today and those castings like most so far have a lot of metal to be removed!!
