Bruk
ABSOLUTELY OUTSTANDING!
Alex
All I can say is, "Wow!" As Bill & Ted would say, "Most excellent dude." That is so real when you put the top back on it is going to be so amazing.
@gunrunnerjohn posted:That's amazing Bruk, the 3D parts are the icing on the cake, they work great! Did you do the design work on those? Who printed them, and what material are they made from?
I see Jon took you up on the funding offer.
I'm guessing you've already done a test fit of the boiler shell, right?
Yes, I designed all those with my 3d CAD Fusion360. I had Shapeways print them in their PA12 Glass infused material. Ill probably use their “Versatile Plastic” next time...(higher temperature resistance) thats why this conversion took so long...lots of trials and errors.
-Yeah I saw that....we can start a gofundme 😂
-oh yes everything fits. Ill make another video later tonight.
Outstanding work again. Put me down for the crowdfunding - a book from Jon Z. is a worthy cause! 😃
I'd chip in on a book about Legacy from Jon, count me in as well. 
Update:
Here it is!!! Some video clips with the shell on!!
Don’t mind my floor, I have cats. 😂
-I’m running into issues using the OG smoke unit. After a few minutes of running it is giving me a fault. I was having issues before. During testing. I’m probably going to have to switch it over to a matching smoke unit that was used for the whistle steam and redesign the smoke funnel to fit. Oh well....tried to save some cash. Didn’t work out.
I have a fat order coming from Lionel, so ill wait till then to start dealing with it.

Holy Smoke! Seriously.
Very impressive Bruk.

Well, that's a awesome as I thought it would be, I'm insanely jealous! 
I don't understand why you can't use any smoke unit, as long as the resistor is 8 ohms and the motor is good, how would the electronics even know?

See I thought so too! I swapped it out the 27ohm with an 8ohm. It get so hot (on High) it melts the solder, and I replaced the fan motor right before the video because it failed. It ran for about 10 minutes then failed again while I was filming.
Maybe, I have a defective RCMC board. With a bad smoke output. Ill will test later will an “updated smoke unit” see if does the same thing. 🤷🏻♂️
I have another coming for Valpac’s T1, ill see if that operates differently when it shows up.
Bruk, this looks and sounds amazing. The smoke is perfect and the 3d printed parts look like they were worth it. Great work as always.
It shouldn't get that hot, but you may have to use higher temperature solder. Also, perhaps your resistor leads are a bit too short, maybe too much heat getting up there. I have noticed that MTH smoke units must use high temperature solder, I have to turn my temperature up for those to remove the old resistors.

Impressive work Bruk. Regarding the smoke unit, does yours have a thermistor? If it doesn't and the smoke control board is looking for one that might be what is causing the error. The early RCMC Legacy engines did not use thermistor smoke units but most of the later Legacy engines with RCMCs have thermistor smoke units.

I've been looking for a chart like this, I was running into similar problems with my 3rd Rail T&P conversion.... I just acquired a roll of Sn63Pb37 but that's mid range says the chart.

I used a earlier RCMC without the thermistor. I originally I wanted to reuse the OG smoke unit, So I knew that a newer board that supports the sensor wouldn't be acceptable.
I'm at a loss why the smoke unit would run amuck, I can't see how the board has any sense of what is connected. If it sees a good smoke fan and an 8 ohm resistor, it should be happy.

After I cooled down from disappointment. I swapped the whistle steam and main smoke unit plugs on the board last night to see what was going on. The whistle steam smoke unit did the same thing. (Ran for a few seconds then stopped. The cab light doesnt flash anymore. So its the board. Shortly after messing around with it. It completely failed. So ill have to order another one at some point.
It had to have been defective from Lionel.
Bummer, at least that makes more sense than the board magically seeing it has the wrong smoke unit and complaining!
Its beginning to look like these fan control boards are the Achilles heel of Legacy. I had one fail in my Vision Hudson and a friend had lost two in his Vision Niagara. Just like the AC regulators failing on older engines.
