The Home Machinist!

Hello, just my 2 cents: For our engines are running all about the same speed (as Anthony pointed out already), steam consumption depends mostly on the effective drawbar pull. This is about 20 % of the friction weight (max) of a typical engine. Specific steam consumtion per hp - hour is about 50 poun...

Anthony, Received your small injector some weeks ago. The German customs had to be paid, but no problems! Now I mounted it to a medium size stationary boiler as main feedwater supply (photo). It works as promised and intended :D : - succing water from about two feet below, - no dripping / water inle...

Hello fans, During two meetings at Oberursel and Kassel the A ran very well :D . A friend of mine worked as engineer most of the time with passenger trains and had fun. The power reverse now works on hot (boiler) water as intended. The stoker had some difficulties regarding the movements between loc...

Hello Russ, Your engine looks fine with all those useful details! Should be a pleasure to it's engineer. Maybe the reason of trapped air in the water glass is it's height above top of the boiler? Should not happen when under steam yet. Installing double checks in the oil feeds sounds so right! I did...

Hello steamers,
Just some photos of my A 1239 steaming at the new site of the DBC-T. It's a combined 5 " / 7 1/4 " railroad near Frankfurt /Germany which was renewed during the last three years. All went well at this first steam meeting, we had fun !

Best regards

Hello fans, Just one more step to finish the project: The working power reverse :D All parts are made of bronze or stainless steel. It's now working on air but is intended to work on water taken from the boiler :idea: . Max force is about 80 pounds, travel is + / - 21 mm. The (plastic) piston ring i...

Congratulations, SF 2900!
Your running gear looks awesome from any angle !
You may be able to run your engine on steam to the same schedule as the prototype 2926 will do!

Best luck to you by

Hello,
one more photo from the first day of the actual exibition at Dortmund. The A is running onthe stage by air.

Thank you Tim for your interest! Tomorrow the A will be shown on the exhibit 'Intermodellbau Dortmund' running on air. Thus I worked a little harder during the last weeks to get it completed. Here's a photo of the driver's side of the cab including the 24-RL brake stand. The (upper) independent brak...

Hello bill4227, You're looking for suggestions how to built your roller stand? For my class A I found a simple construction using pairs of standard ball bearings. Thus the driving axles take a stable position :idea: . Rugged ball bearings of some diameter improve running a great deal compared to sma...

Hello Anthony,
Good news!
Tried to order one piece, but found your website won't accept anything else than PayPal (no MC or Visa credit card f.e.)? Any other posibility?

Hello Mike,
No problem, as long as the support of the disc by a (complex) curved disc is made carefully. That is recommended to avoid stress to the diaphragma, anyway.
Years ago I built a similar brake reduction valve which is still in use.
Best regards
