You've certainly done it again Bruce!! 

Off to watch the video soon...

By the way, that tag is very nice too! Have a few Jensens here from that era that are missing them.

Also think it looks better with the wire sight gauge protectors and one whistle/one SV

"Also think it looks better with the wire sight gauge protectors and one whistle/one SV"
I strived to use identical wire sight gauge protectors on this project, I specifically bought 4 #35's that had them, I think they look neat , plus they're a treat to set up....the wire slides out of the way so the nuts can be tightened without removing they whole assembly.

Very nice.  Custom work always impresses me.

The boiler crossover manifold with the pressure gauge fitting, did you make it?

I did a timed run last night to see how long a full fill would run from top to bottom of the sight glass, I got a 1hr 21 minute run with the juice cut back to near minimal, oscillators wont run all that slow, but interestingly the engine on the left runs easier & at a faster clip, but the engine on the right will run @ less pressure.

Possibly a slight difference in pivot screw tension, or port hole diameters or positions?

So many variables in a situation like this, but so what if there is a slight difference between the two when running free. Put them both under different loads and they'll run however they need to in accommodating that resistance.

Another way to go might be to put exhaust throttles on both of them so they can be individually tuned and balanced.

Neat design.  Thanks for sharing!

Re: "Another way to go might be to put exhaust throttles on both of them so they can be individually tuned and balanced"
I had given that some though because I knew there would be speed differences in all but wide open running, I thought about making a spacer plate in between the boiler mounted steam chest & the boiler, but in the end I didn't think it worth the effort. one way to stabilize/time the running is to have them (drive axles) linked together, & that is the reason for my part #2 engine build (yes, your hearing it here 1st ) this one will have 2 #35's with the axles facing inward & joined by a Jensen #25 heavy flywheel, I'd like to incorporate ball bearings into this model, but that would take some doing as there is not enough extra material on the stanchions to allow for the extra room needed for the roller bearings...needs some thinking on. I had always planned on building both of these from the onset & have all the needed materials on hand, this one shall be called J-42R, I haven't done a build thread for years....but if there is enough interest, I would be willing to start one for my fellow steamers/friends.

Oh yes Please Sir ... can we have some more!!!

Yes please Bruce! I am interested!!

I am definitely interested Bruce!
