The "Little Pearl" Single Cylinder Marine Engine

Plenty more bronze to go Chris. I haven't weighed it but guess that what you see is around 5 pounds now, maybe more.

A bit more done on the cylinder yesterday just didn't' have the chance to post the pictures yet. Two more 1/8" holes needed to be drilled opposite the steam chest through what will be the cylinder bore and intersecting the previously drilled vertical holes (photo 1). Most of these 1/8" holes will be plugged prior to further machining. In photos 2 & 3 I was checking squareness of the cylinder in the vise and drilling the three mounting holes for the arm that holds the valve link rod. Then flipping the cylinder over the two holes for the steam/air in and out were drilled and will be tapped 1/4"-40. The last photo shows milling out the steam chest area. Again the middle three holes shown will be plugged prior to final machining of the piston valve bore. While the cylinder is still in this configuration, I will drill the holes for mounting the steam chest cover today. Its coming along but still plenty to do to finish up on the cylinder.

Looking great! Always fun to keep track of directions when doing that many passages.

Very true Chris and there are a lot of them in this cylinder. A few more pictures from this morning. First drilling the six holes for attaching the steam chest cover (photo 1). Photo 2 shows how the steam inlet port breaks through into the steam chest. Lastly is the cylinder with the link rod support and steam chest cover in place.

Not a lot of shop time this weekend, but did manage to get the cylinder part of the casting rounded with the set-up shown in photo 1. The other two show the head sub-assembly and link bracket in place on the cylinder. Hoping to get the piston valve and piston bores finished in the next day or so and then move on from there. I still need to plug a few of the 1/8" holes as well.

Every little bit helps, Bill.  And it looks quite nice too!

Just checking in on my own build to see where I went . Not to worry, it has been a busy two weeks with advising for summer and fall, so haven't been able to get down to the machine shop as needed. Hopefully next week will see some progress.
