I'm taking steps down a road that, hopefully, will result in a complete set of rudder hardware for the Brewer catboat. The furnace is made and operational, most of the materials required are now on hand. I'm going to post some pictures and make some comments about the patternmaking and ,soon, the casting. Anyone who's done this before may feel free to make any suggestions, because I'm feeling my way along here.
This is the beginning of the pattern for the lower gudgeon, which attaches to the aft end of the keel. It will be a split pattern with two cores. The turning has been glued up with a piece of newspaper in the joint, which will allow the piece to be split lengthwise. A simple diagram has been drawn on plywood to provide a guide and help with the visualization of the piece. The turned piece in the foreground will become part of the lower pintle.
Here the pieces have been split and some brass alignment pins installed in drilled holes.
It doesn't look like much yet, but I can't tell you how many hours I've spent mentally going over and over this process in recent months.
