David:

I like your paper alignment drawing stuck to the end of the liner. Shades of Jack Bodenmann and Dave Sclavi, and just like them, it turned out nice. I never have used that technique but I'm boing to start

Jim:

Beautiful job. Nice castings. I notice the exhaust ports up through a round hole, different from American practice.

Attached are some shots from my collection of a new 25NC under consruction.

Nice work Jim. I’ve been following your efforts on your website and I like your pattern, machining, and assembly techniques. The 25NC is my favorite SAR locomotive. It was a lot of locomotive slung on 42” gauge and your model for 7-1/4” will be impressive. Reminds me of when Bruce Ward and I were at...

I think the beer, and margaritas, are essential tools in getting the job done. I know that after a hard day of modeling/machining - well, I think I have fallen offf the bar stool at Applebees on a couple of occasions.

Installation of drifting valves on modern piston valve locomotives was not a universal application. Some locomotives, including the NKP Berkshires, were never equipped with them. NKP’s operating practice dictated open throttle running that is, using the brake and cutoff to operate a train or locomot...

David: Actually, the Berkshire chassis that I have right now (It will be on air next week if all goes well) is the fifth one that I have put together and everyone tells me that I'd better keep this one, so I think I'm going to. I've run four other Berkshires that my customers have finished so I did ...

Jim: You are probably referring to Vaughan Cherry. Vaughan has had some health issues and never did too much more with the locomotive. It is very well along and has been steamed, but not finished. Glad the parts could help you on your 25NC. I guess the Berkshire had some rather well proportioned par...

Mike: Yes that is the same engine that was at Bitter Creek on the 4th of July. In about a month Tom and I are going to have my chassis on air and then start the detail treatment on it. Tom says that he visualizes a meet in southern California with four NKP Berkshires there under steam: Peter's, Tom'...

Tom Lawson of San Bernardino, CA just got his engine on air. Now the detailing begins.
Two photos attached.

Dave: Perhaps a good way to put this is that the pressure rating is nothing more than that, pure pressure. It does not take into account the potential energy (expansive energy) inherent in the fluid being contained. A compressible fluid, such as compressed air, contains a lot more of this energy tha...

Guys: Thanks for all the nice comments about the Berkshire. I tried to put together a model which would be a pretty good representation of the prototype. They seem to have turned out well and have been a rather popular locomotive with live steamers. Dave Bortz; It was your dad and Wayne Karn in Mich...

Here are some of the first castings for the Pyle National NKP number boards.
I'm working on some mold tweeks and the electrical stuff, but progress is being made.
