The Home Machinist!

Hello Jack, Yes it was, indeed! The VSM / NL has up to 11 steam locomotives, some guests come to that special meeting every first weekend of September. Those 105 pieces of class 23 engines were produced in the mid-50s as modern (and last) replacements for elder steam locomotives. Their wheel arangem...

Hello friends, Progress had been slowed down due to several steam events which called for a visit, sorry :( . Here are some more photos of making the air cylinders of those CC-pumps. Same method used as with the steamcylinders. Bores were made a bit smaller (30 / 20 mm) to achieve safer action at me...

Hello Hoppercar, Yes, 0.001 x diameter for shrinkage will do perfectly. As recommended above a shoulder will help to achive a precise seat. Just recommend to turn the raw outside profile of the tires, too once they are on the lathe to turn the inside fit. Makes finishing the complete axles between c...

Hello Jim, Using 2 or 3 rows of drilled ports instead of milled rectangular ports works fine, too. There are no restrictions as long the diameter of the drills is below the width of the piston rings. Total cross section thus maybe up to 40 % of diameter x width x pi (liner port). Just my two cents. ...

Hello Jack,
Your shiny reflectors are looking great, indeed!
For I used a similar method for making all sorts of covers (from soft stainless steel), some more photos may be useful to other modelers .

Hello Geof, Now there is some progress with my CC-air pumps. Method of making might be of interest to other modelers, too :?: The sand casted steam cylinders made of bronze worked out as intended. The idea of casting a mandrel :idea: helped a lot turning the LP bore and the bottom side very precisel...

Hello pollockmarine, Built one for may class A of 5" gage (scale 1 in 10) last year. Works fine on air and boiler water, too. I prefer water from the delivery line of the water pump (or the injector) due to the lower temperatur, yet. My fit for your model, too? For more information, please see my to...

Hello Jack,
Indeed both your method and finished parts are perfect!
