Love how it's coming together Bruce and thanks for sharing it step by step.

I got a few more things done.
the heat shield is formed ,although I didn't seem to get any photo's of all the finished holes or paint done
chimney stacks bead blasted & one of the holes taken out
heaters in place
heat shield & wiring finished , quick disconnects used.
now just waiting for the cross-over manifold to come back from the nickel platers.
Wow!
You have been busy Bruce.
Thanks for your efforts on this build thread.
This is awesome!
Thanks Bruce, your extra steps like blanking off the hole in the stack support definitely pay off in the end
I spent several hours on it yesterday, replaced the split axles with a single axle...no improvement on the ease of turning over, I got is down to 3 psi before stall, I will run it in some more today (on compressed air), it seems to improve all the time as the 2 engines break into themselves. I put the cord on & tested both heaters, they work correctly & at about the same temperature on the short test I did. I finished up the plinth with a little wood putty in the voids, careful sanding & a stain of Early American with polyurethane over that once it dried (with the Sunshine we had yesterday...it didn't take long) I'm not happy with the chimney delete on the smoke stack as I can still tell where the hole was, will be re-doing that better today. now I'm just waiting for the cross-over manifold to come back from the Nickel platers (probably still a week away) & with any luck it should be finished.
I'm still waiting on the Nickel plater to get my parts done, but have been steaming it often the way it sits now & enjoying it immensely.
I performed an endurance run this weekend of my J-42R , I filled both boilers to the very top of the sight glass & ran them for 4 hrs non-stop with "on the fly" oiling every hour, this was on a homemade variac & I had it running at just above stall speed, as the water was being used up I could incrementally turn the variac down. one boiler still showed 1/8" above the bottom sight glass nut ,while the other was right even with the bottom nut, had I pushed it, I feel I could have gotten another 30-45 minutes out of it if I wanted to....but this was plenty. very pleased with this plant.

Bruce, 4 hour run has got to be a record for for a standalone Jensen 35, let alone your double boiler version...wow! It sure runs silky smooth!
Rog
That sure does run great and looks great, too!
Excellent result Bruce.
A wonderful 4 hours of steaming....for sure.
The Jensen J42R is now finished ! all the parts are now in place, & here is a rather long video of the plant, I hope you enjoyed the process & thanks for following along.
