The original query reminds me of a line from the film 'Crocodile Dundee', the scene where Hogan is accosted by a knife wielding New York mugger. "You call that a knife?" (pulls his own huge weapon from sheath). "Now that's a knife". By a strange coincidence, I received a query from a US customer only this morning on the very same subject, large Puffers, but 'large' clearly means something a bit different in South Carolina. The guy had sent pics & details of his latest model, a 65" x 21" Maine lake tug, it has a twin cylinder 0.75" bore by 0.9" stroke steam engine and swings a 5" four bladed prop. I'll quote a few lines from the e-mail on what he's planning to build next.
.......What I am contemplating is building a model of your Puffer scaled up three times to 1½" scale, that would make her about 96" LOA x 27" beam just about the correct size for my 2 cylinder steam engine 1.5" bore x 2" stroke to be fired on oil, I hope. Love steam and like to be different ( don't want to go to the dance and have the same dress as some one else as they say!!). Would it be possible to sell me a set of plans and any pictures you have of your model Puffer how much would you charge for the plans/pictures & postage? Love the Puffer, short and squat, with the stack in front of the pilot house etc. Thank you in advance!
Yes that's what he wrote, an eight foot long Puffer with a 27" beam, and a 1.5" bore x 2" stroke oil fired twin cylinder steam engine to power it, just imagine what it will weigh. "Now that's a Puffer!".
