FYI on readers of this - Chris' RP work is rather astounding - the N (not Nn3) version of the Porter 0-6-0 into my Porter 0-6-4 version is well underway with mechanism testing, since I got the full actual drawings of the locomotive from the Porter collection in the Canada museum. It's a go. His frame is running around on the Hickory Valley with Toma N wheels, gears, and motor, and I'm designing the locomotive around it. Dimensionally there were some surprises as mine is officially a Porter oddball apparently never repeated (got the Porter book to prove it).
But salute to Chris, this is rather incredible printing and tolerances and part finishes. I knew that RP would progress to this, it's now in my hand.
The only thing I'm doing to marginally add to it is my own metal casting, we'll see how that goes. I want to get this little further along before I blend it out to my own build thread here.
But when he says 'he could do better', yeah. Go back 55 years and Walter Brennan had a repeat line in a western that applies. "No brag, just fact".
