Re: Fire Canoe? (Continued)

So I was able to exchange some emails with Jack Thompson the other day who was very generous with his time and knowledge. Here are some more details about Fire Canoe:
FIRECANOE's hull was purchase from war surplus in 1947. They operated it the first two years with the 4 cylinder Buda gas engine. Then Thomas wanted to put his steam engine in a boat. Accordingly, the boat was turned over to him.
His engine was a home built engine done by a professional machinist that copied much of it from a commercial engine. It was about 3"x 6"x 3 1/2"stroke. Thomas installed it and had the boat in operation for spring 1949 and operated it every year until 1999. He had around 12,000 miles of steaming during those years.
Thomas went thru about 6 boilers during the life of the boat. The reason was because he burned wood recovered from the salt water. One of the boilers had been swamped after 4 years when the FIRECANOE was left on the beach. The salt water penetrated into the kaowool(sp) insulation and rusted the tubes quite badly during the winter lay-up. All his boilers were made using black iron pipe except for the main steam drum that was made from seamless steel tubing he scrounged from the scrap pile at the Shell Refinery where he worked. At first he built the drum cross ways to the back of the boiler, but changed this and ended up with the 10 inch drum vertical. The boiler design is more or less a "Roberts Boiler". Thomas made his boiler about 70 square feet of heating surface plus an economizer of 4 sq. ft. The majority of the heating surface is 3/4"schedule 40 pipe with three passes in the boiler with the tubes entering the headers. The mud ring was schedule 80 3" pipe. He had about 15 inches of firebox space between the grates and the overhead tubes.
(I thought this story was particularly interesting) The Indian style bird painted on the bow of the FIRECANOE evolved over a number of years. First, it was only to be an eye similar to what the Greeks placed on their boats. The he decided to make a raven head of it and since the eye was too close to the bow, he had to turn the bird beak down and made it an eagle head. Then he expanded and drew up the rest of the eagle body by referencing some Indian art.
