Absolutely gorgeous David, wonderful machining.

Add my well done and add my very well done to the pile of accolades.
Absolutely superb!

They look nothing short of amazing !!!
Can certainly see why you´re exited to have them Daniel, and yet another "Very well done" to David.

Here's a couple of the images that provided the information for David to create his artistry.

Geez how nice is that !!!!

Thanks for the details David!

Thank you for your kind comments chaps.
This was a nice little project that I took on for Daniel and as he said the main issue for me was the size of the lettering at just 1.3mm tall. I used some tiny ball nosed cutters of just .3mm diameter. I did initially try .2mm diameter but these didn't last as they were just too small for my machine as I don't have enough rpm. But increasing the diameter 50% to .3mm made the difference and were still small enough to get the detail I needed.
The fixing hole in the back of the plate is M3 and I thread milled this using a tiny .5mm pitch threading tool. The advantage of using this is that I can control exactly how deep the thread is going to be. So the pilot hole was 3mm flat bottom (overall thickness of plate was 3.6mm) and the thread was milled 2.8mm deep. Daniel informed me that the fixing screw protrudes 2.5mm from the door.
The two finishes I used were high temp enamel for number nine and brass blacking solution for the number 4.
Cheers
David

These are awesome.
I want one or two or three of these! 🤠

David is a true craftsman, i'll always regret not getting one of those wonderful Tribute engines from him.
Great to see those nameplates he did for you!
-
Collectible by themselves!

Nice Work David! 8)

Oh my....those are lovely, the detail is exquisite !
-
Great work from David - his meticulous attention to detail translates into beautiful finished pieces.

Our good friend David (vpro) is known to make really fine nameplates for locomotives, traction engines and even stationary engines. He is also known to have been the machining genius behind the spectacular "Tribute" authorized copy of the Saito V4PR four cylinder steam engine many years ago. A few years ago I asked David if he could perhaps also make Baldwin locomotive number plates, as typically mounted on the front of the smokebox door, in 1:20.3 scale. He studied the problem diligently at that time and determined that he didn't really think that he could. Forward many months, and with more small letter machining under his belt, he has another look at the problem, and decides just maybe he might be able to make something that sort of resembled what I'd been after. So we crunched the numbers and scaled down from my photos of the real thing, and worked it back and forth a few time, what with me giving him some wrong info a time or three and all, and he finally gets back to me saying that "Yes" he thinks he can do it .... maybe. I gave him the go ahead, and he gave me .... THIS:

... or rather ... THESE:

These are slightly smaller than a US nickel and the writing is also slightly smaller than what is on a US nickel, which is nothing short of amazing in my book, and they just arrived here within the last hour or so .... OH BOY!!!
Mounted the main one up as seen in the first photo and it fit to perfection even hitting the critical mount screw hole depth perfectly so that it locks up firm without the screw bulging the face of the plate. All this precision from a distance of about 1/3rd of the way around the world!
Needless to say ... I'm ecstatic and really don't know how I could be any happier at this outcome.
I should add that any flaws that you think you might see in my photos, are only shadows and light reflections, artifacts of my photos, not of the pieces themselves!
