Hi Glenn I have been off line a while myself and am also in catch up mode, Nice work on the chimney, ouch on the situation of having to do the rework on the paddle wheel. I am curious about the thickness of the chimney though, It seems to be a little thick would the actual chimney have been 1/4 inch thick? or did you choose that thickness for a different reason?

Well, I started the week off with a major mistake. I had hoped to finish the engine this week but, while adding the spreaders to the paddlewheel flanges, I realized that I had them reversed on the port side. The inboard flange was on the outside and outboard on the inside. It was pretty frustrating heating and desoldering the blackened parts with the spokes in place. I always lightly peen the end of the bolts so that the nuts won't back off over time. Makes for a secure hold but impossible to ever disassemble without cutting the heads off. After finally resoldering the flanges and burning some of the spokes, I noticed that the notches on the after edges of the ends of the spokes were now on the wrong side. I spent a good part of the week making new spokes and I'll have to wait for a new batch of 00-90 screws to arrive.
After several attempts at different methods to make the chimney segments, I finally came up with a method that works well. The tubes taper upward by less than a degree which allows each one to fit tightly inside the one above. Using AutoCAD, I calculated the the upper and lower radii and the angled sides of the plates needed for the segment. I added 1/8 inch on one side for overlap. Printed on label paper and applied to the brass, I cut out the .01 thick plates. As long as the rigth edge lined up with the inner line on the left, the shape came out accurately. The individual segments mated perfectly giving me a nice straight tube. I was able to make four segments in less than thirty minutes. Unfortunately, I ran out of brass before I could make a complete tube.
Kevin's drawing of Heroine's chimney.
Paper patterns for the chimney segments. The edges look straight but, the sides taper less than 1 degree and the top and bottom have a extremely large radius (152.36 inches for the bottom 149.86 inches for the top)

It will be prototyping on 3D printer, then cast metal
