Todd, The tender joints are not exposed to heat and could be soft-soldered. However, silver-soldered joints are stronger. But here is the real motivation for silver-soldering - Kozo's plans have you getting a lot of silver soldering experience with various parts before you tackle the...

Terry, Thank you so much for this thoughtful review. There were years of effort that went into making the book, and it means a lot to see some recognition and appreciation, especially coming from such an accomplished craftsman. There was an uptick in orders after your post and the book...

Here is a drawing showing how I make the clamps. There is a link below to flickr. Hose Clamp by Ed Hume, on Flickr Regards, Ed

Robbie, Crueby, Yes, I mention these changes now so you can ponder and evaluate them ahead of time. You can buy coils of stainless steel spring wire, 0.015" thick from McMaster-Carr, P/N 9665K84. The coils slip perfectly over 7/32" OD silicone tubing with no tendency to unwind. The silicone...

Robbie, Here are my suggestions to simplify the plumbing challenges near the end of the shay project. I think we want to hear from Crueby what his opinion of these changes are. Move the lubricator and mount it on the frame. Do this by adding 8 - 10mm length to the front of the...

Chris, Your progress is amazing! I have a question - back when you made the crankshaft by attaching pieces, did you make the eccentric diameters a little bigger to provide some margin around the thin side when you drilled for the shaft? Asked a different way, if you did it again, would you...

I have made my crude sketches and CAD DXF files available in the download area - http://www.homemodelenginemachinist.com/downloads/butane-burner-for-gauge-1-kozo-new-shay-by-ed-hume-312.html . Let's not hijack Crueby's build thread for burner discussion. Keep any followup limited to...

The download file has been superseded by the much nicer detailed plans in the new Climax A book - "A Climax Class A Live Steam Locomotive Model". The plans include complete drawings for the tank and valve assembly, plumbing connections, and burner system. There are 3D perspective views as well...

Hi Crueby, Thanks for the praise. The butane burner is my own design based on ideas from Morewood's Raritan propane burner. It is working well and it is convenient. I have a mix of hand sketches and CAD files for the parts. I'll look into pulling the materials together, but not before this...

Hello Crueby, It is a pleasure to see your work. It is no big deal not to slot the piston rods. The best way to adjust the rod length is to not mount the cylinders. Instead, use calipers to measure the height of the piston top protruding above the frame part where the cylinder is mounted...
