Locomotive Cab

Can anyone point me to a description of building a 1-1/2" scale riveted steel locomotive cab? I did a search here but didn't turn up anything. Dave has described some of the details, but at this point I'm just looking for the box. I thought that seeing how someone else had done it would give me some...

Re: Live Steam CNC Defender

I've often wished I had a cnc mill, but here in the land of no industry it's unlikely I'll ever get one. As Dave shows, many parts done on a cnc lathe can be done on a turret lathe. I'm not aware of a similar substitution for a cnc mill or machining center. Just out of high school I took a machining...

Re: WHO NEEDS CNC?

threading gizmo A releasing die holder for acorn dies. Used with a bed turret. The turret feeds to a stop. As the threads continue to be cut cut after the stop is reached the holder for the die pulls out and releases by spinning freely. The lathe is then reversed to back the die off of the thread. ...

Re: Looking for ASME safety valve

There are probably many hundreds of the short Kunkle valve for unfired vessels being used on small boilers. Has anyone heard of a regulator having an issue with their use?

Re: USATC S-160 Consolidation

The truck is finished. Now I can finally move on to something else.

It's about 95% true to the prototype drawings. The bearings and journals are the only major deviation.

Re: Re-facing Slide Valve & Ports

On material selection - what is a good material to use for the steam and valve pistons when SAE 440 bronze bushings are used for cylinder liners? I thought it would be good to not use cast iron to stay away from any rust and pitting. Should stainless steel be avoided due to potential galling?

Re: Electric wheelchair motors

My impression is that battery-powered tools have driven a tremendous improvement in motor designs and materials over the last 30 years or so. Using a really old motor is probably something to avoid.

Re: Whistle advice?

Another source I have suggests C, D# and A#, which were supposedly used on Army locos in North Africa during WWII. I can verify that the USATC "S-160" Consolidations, which were used extensively in North Africa before being shipped to Europe, used a single chime whistle. References are the BLW and ...

Re: Whistle advice?

At Railfair in Sacramento around 1991 there was a 3" scale 15" gauge Shay (which used Andres Case traction engine cylinders) with an interesting chime whistle. It had chambers that doubled back on themselves on the outside of the whistle to get a lower tone. My recollection was that it sounded prett...

Re: Electric wheelchair motors

Wheelchair motors should be a lot more robust than scooter motors. They should also have plenty of power as I would expect them capable of moving 250 pounds up an 8% grade (1:12 is the maximum grade that should be used for handicapped ramps.) I've seen one switcher where the motor shafts were mounte...

Re: source of drawings

My 2 cents on the N&W Historical Society. I've obtained a couple of hundred drawings from them and other archives. Their web page is one of the easiest to use, they are prompt, and are among the most reasonably priced. In addition to N&W drawings, the collection includes some that they have drawn fo...
