Miscellaneous
Hi, being away from home and waiting for my delayed flight I am testing, if I can post from my work address. To make this more than just a test, here some informations/thoughts: Recently I read (mylargescale?) about the position of the coupler relative to the boiler center line or frame center line of a shay. Well, usually it is centered to the frame, but there is at least one exception: The (front?) coupler of the Diamond & Caldor Shay #4 was below the center line of the boiler. Reason: The locomotive was used for shunting narrow gauge/standard gauge cars on dual gauge track. See: http://www.edwrf.org/shay4-1945.2.jpg This is one of these occasions, where a beginner might do something "wrong", the advanced modeller does it "right" and the "seasoned" one does it "wrong" again - but with a prototype to prove his decision ! Now to something completely different: The Angels Camp Branch of the Sierra Railroad had these famous short coaches/combines, which unfortunately are standard gauge. Does someone know of genuine 3' equipment of about the same dimensions ? I would like to build a short combine for my logging branch. Regards Henner

Henner, Thank you for the gear ratio info. I have a similar project that has been in the works for a while that will use a 1:5 ratio from the crankshaft to the wheels. The engine uses oscillating cylinders from a Jane 0-4-0 loco. The Jane runs well at low speed with no gearing, so I'm hoping that 1:5 will be about right. No problem with the metric measurements. When I started with this hobby I decided to model 16mm to the foot. Therefore I did all my construction layouts in metric, which allowed me to gain experience thinking in terms of metric units. Now I use both English and metric measurements together depending on the need.

I started out with a 1:1 ratio for the engine/main shaft but the locomotive was too fast. The engine has an 8mm bore and 16mm stroke (Sorry, I am a metric guy..). I am almost done with the CAD drawings of the engine and we will post them on David's site. Regards Henner Message text written by INTERNET:[EMAIL PROTECTED] Henner,

Re: Miscellaneous
Jim, the boiler is basically a coupler for a 2" copper pipe. The inner diameter is 2" and the length about 3". Some couplers are shorter, the longer ones are a bit harder to find. There are 3 tubes 1/2" inner diameter. Both shell and tubes are turned down to about 40mil wall thickness. For the shell the thickness should not matter, however for some strange reason the boiler seems to steam better. Regards Henner Henner The pictures of your Climax on David's site are great,thanks to you and David for hosting them on his site. Can't wait till We see the cad drawings.What are the pertinent dimensions of the boiler,Diameter and length etc. Thanks again. Jim O'Hearn
