Hello, I've been planning on building a large clyde puffer. Around 44" long. I would like it to be steam powered and after a lot of searching, have come across Malcolm Beaks MB22, along with four possible boiler designs. I have read that the MB22 punches above its weight, so should be ample power for a pottering puffer. After further research I've found Malcolms reversing gear also. The gears have been ordered today, and will arrive in a weeks time from a well known auction site. I figured with the engine and boiler built, I'm at least half way there to finishing, and it's smaller to store than a 44" hull. Also means I can build the hull to fit the mechanical bits.
I have read that Malcolm made some ammendments to his original design, which would be handy to have. I would be very greatful if anyone who knows Malcolm could pass on my enquiry, or if anyone has been sent the engine upgrades please may I have a copy.
One addition that I can think of is to add an engine driven pump and bypass.
Jon
