Lego Four Valve Corliss Style Steam Engine

Quite a stunning engine, there's plenty to see on this corliss. I tried to make it my most realistic to date. I even tried to make the exccentric look authentic. It took a full week to get her up and running, but boy does she look great! I just wish I could have used rotary valves rather than dual piston valves for the power and exhaust stroke. The valve gear was the most diffucult part to finish, In the end I even had to lubricate the valves for the first time ever on any of my enignes. She just would not cooperate unless I did. And the governer is just for decoration this time, but I am working on an actual working model, but for now it's just for looks. Hope You Like it, DAH.

It would be cool if the governer worked :)

@questionablesight  I know! :D I am working on that!

Well, yes and no. That is the engines top speed at that power level on my vacuum, there are two more each higher a power than the last. And sence I had some valve issues it has a little longer cutoff than my other engines.

Nice engine! I like the way you built the connecting rods!

@invendr Thanks, they took hours to get right.

Holy $^%& That. Is. AWESOME!

[mechanicsnut]

@legokid900 Thanks so much, But I may make one more video of it in better light.

[toecuttergpx]

is this the engines top speed?

@kenrely Im sorry, I cant get my videos onto windows movie maker to adjust the sound.

[kenrely]

your killing me with the sound on this.
