well, same result..... its empties the water over into the smake box.

I think I will try take the dome off, fill it halfway, and fire up the boiler, and see if the water is foamming or something when boiling.

Got it running.... I dont know how exactly.... probably a combination of things

I boiled the water in the boiler itself twice without the steam dome and safety valve, and poured the steaming hot water out of the boiler after a few minutes of cooking

......I figured this should remove any possible flux and detergent maybe left in it, causing it to foam up. Rinsed the boiler with hot and cold tap water for several minutes...

I also dismantled the smoke box, and found it was glued/sealed to the boiler itself making it 100% watertight.

After putting it together, the water leaks out the bottom, which I think is a good thing, instead of filling up the entire smoke box with water.
I also ony fill it up about 80% of the max mark.

Here it is with the throttle slightly open, going slow.....

Thats better! It will take a few runs for it to run in more but once it is, it should rocket round that track

.

The smokebox is usually a really really tight fit to the boiler! It doesn't have to seal anthing though!

Ive never seen a loco throw out water like that before

I'd take the cylinders off after that, as water in the cylinders can damage it and the pistons! SJN, how on earth do you move in your apartment/flat?

Possibly, although it probably wouldn't have caused cracking. More like the lining on the inside, also it would wear the piston more quickly

Water in the cylinders causing trouble?

Never heard of that one before! I certainly would not remove the cylinders, once fitted best left on, any disturbance either to the port faces or the gaskets, particularly after it is run in, is likely to cause more trouble in the form of steam leaks than any benefit it might have! It looks like it is running nicely now - if it aint broke don't fix it!

I took the cylinders off my loco a bit back to oil them. The bolts were a bugger to get back on! Ran loads better though

Great video. It runs well at slow speed but it really slows down on the curves. The flanges must be tight on that radius.

If that had been real life, I can just imagine the accident report: "loco collided with sub-marine but carried on with test run..."
