So i almost finished it today.

then i realized i had the piston control valve plumbed in the wrong order so it would do one cycle then get suck blowing steam out.

So there’s the piston and flywheel made. 4/5 parts done.

I’ll go back to the hobby shop and grab some more pipes and hopefully get this thing finished by the weekend.

the theory behind my design is solid, it’s just hard as **** to solder in three pipes into one small barrel then clean out the center without ripping the three pipes off or deforming it.

also the boiler is much less cute today. i forgot to fill it properly when testing and half the solder joints on the bottom melted then the boiler turned pink again from heat. looks ugly. oh well.
