Thanks for the interest. These are for a carriage that I am building for a Customer. It is a Naval Carriage for a 24 1/4" long barrel that I have not seen. It is just a tad under 3" diameter. This carriage has shown me how much I didn't know. It has taken much longer than reasonable, but, the time and agony that I went through, I view as tuition. I am certainly not an expert, but as I see this coming to a completion, I am smiling.
