This is the latest 1-1/2” scale NKP Berkshire being tested at the Maricopa Live Steamers in Phoenix over the last couple of days. It belongs to Larry Kirchner (in the photos) of Baltimore, MD and will be shipped there as soon as the tender is finished (lettering, etc.).
Larry rode the real 759 as a kid, a memory he has not been able to shake.

SO happy to see 759 in operation once more! If the full-scale 759 gets to run, so much the better. There have been many beautiful steam locomotive designs throughout history, but pound for pound, you really can't surpass the Nickel Plate Berkshire.

If this will help I used 3/32 pop rivets for the tel tail stays and I modified the head of an 8/32 bolt to look like a flexible stay and 3/32 copper rivet for the others. I followed the actual Pennsy K4 boiler print for there location along with prototype photos.

Chris:

Like Dave, 3/32" pop rivets were used for the tell-tale stays. They are McMaster-Carr #97519A003. They are specified as .198 diameter but come out smaller than that, around .165, which is prefect because the prototype had 1' diameter stays with 1-1/4" major diameter threads on the ends which, when caulked over expand a little.

3/32" button head rivets were used for the mud ring stays.

1/8" and 5/32" rivets were used on the firebox corners.

Thanks Jim and Dave .

I just ordered 3/32 - 1/8 - 5/32 brass round head rivets from Hanson Rivet in California the other day , just thought I would check I had them right , but I was not sure about the pop rivets .

The original true scale size was 7/8 and 1 1/8 which going by the machinery handbook rivet spec head diamensions ,when you scale down you sort of land in between these sizes .

One thing I have seen from the photos and drawings I have ,there were a few different versions of rivet patterns , so we just have to take the one that I like best I suppose , I'm sure some one will say that's not the right rivet arrangement ,it was'nt like that ,but I will have that base covered ,as I know what the various patterns there were over the years .

I like, and can relate to, your last statement, the one in parenthesis.

Hello Fellow Live Steam companions,
Even though it's been a while since there's been a post on this thread, here's something to note. A Berkshire has just come up for sale in Washington. Keep on Steamin' my friends.
