Re: Threading to a shoulder?

DianneB,
What about turning an O-ring grove of about the inner diameter of the thread to win both space and a reliable sealing?
Please see a strainer as example of a (very short) cap with O-ring grove. That's my practice proven for many years.

Re: Easy 1/4" check valves?

DianneB, This dfferent construction to the usual solution using a stainless ball might be of interest, too. The seat maybe bored by means of a precise drill - or better - a 90° center drill (correct expression? "Senker") on the lathe. The valve made of stainless steel or bronze on the lathe is to be...

Re: Pre heating boiler water

Hello Fender, You're right! Of course both the Elesco and the Knorr system are of the 'closed' type. Sorry for using the wrong expression 'open'! :( A reliable 'open' type feedwater heater like the Worthington or Heinl type is still waiting to realization in model size! Problems are sucking hot or e...

Re: Oil firing in 1" scale

Hello John, Maybe I can help a little bit - just my two cents. A few years ago I had a conversation with James Keith where I answered his questions regarding dimensions of nozzles and such. My life steam model of a DB class 44 (043) of 5" gauge got oil firing from the start back in 1977. It's still ...

Re: Main crank pin on different axle then Eccentric on

No problem at all.
Look, many 3-cylinder engines had their valve excentrics and their middle cylinders at different axles. No issues, no further measures necessary.

Re: WHO NEEDS CNC?

Hello modelers (who are still using obsolete technics now and then), Talking to several life steamers, I detected a simple method to fix hexagon material in a standard 4 - chuck instead of using a 3 - chuck seems to be unknown by many of them? Shift the hexagon material into the chuck, turn it a bit...

Like that engine, the prototype of which will be returned to service next? year, too. I got a lifelong membersh...

Re: Museum of Obsolete Drafting Technology

Hi John, Very nice case filled with good old tools! Weren't bad times these tools were all we had! When I wrote my diploma work, the first HP handheld calculator was a revolution then (and is still fine for technical calculations). At the time I normally used an elder calculator stick which my Prof....
