The cylinder block is coming along. We are using Ed's patented (well, maybe not patented but probably original) built-up method of cylinder block construction. This method was referred to in Bob Reedys article on building an Atlantic in the May-June 2009 issue (I'm pretty sure it was this issue) of Live Steam.
A C-shaped framework was made from 1" plate. The cylinder radius was then cut into the opposing sides of the "C" and holes were drilled through the radius cut and into the cylinders, which were also tapped. (These 3 mounting holes are visible in the above photo). This allowed the main cylinders to be bolted to the cylinder block framework. The intake and exhaust ports were machined into the cylinder and then a bronze liner was pressed into place. This highly classified photo shows the LS God himself pressing in one of the liners! After the liners were installed we then machined the bore to its final 3 3/8" dimension, even allowing for one of my all too frequent "oops" moments.
