Re: Oil burner consumption

Hello RGSP,

Do you have any, at least rough mpg estimations to make your numbers more comparable with the ones posted before by the others?

Re: Opposed Piston Engine Project - The Steam Version

To show now what I did and what I didn't do yet: Friday, the last piece of metal arrived to build the core engine. As I explained, I split the building process into two stages: The core of the engine: crank cases, cylinder, intake-& exhaust register The valve train: timing belt drive (probably), the...

Re: Increasing a VFT boilers output by increasing the firebox size

Hey OP, Excuse my late reply. Yes, it was my thought to use the coil you thought about as a water wall - as like a first part of the evaporating surface before going into the boiler vessel, which has the smoke tubes as the second stage of your evap surface. It would be a compromise for not needing t...

Re: Increasing a VFT boilers output by increasing the firebox size

Hello I am not totally sure if your boiler has a wet or dry fire box. To vertically enlarge a dry firebox with no increased grate size is not worth the hassle. You could do what you described and use a coil, but this would be more like an evaporating coil like in a WT. but I would NOT place a coil o...

Re: Opposed Piston Engine Project - The Steam Version

Thank you for your answer. I quess it really shows up eventually if you buy cheap tools. As a student, I was only able to buy a relatively cheap drill press, whose drill table bends down under very little pressure. Now, I just use a short length of a very big suspender as a table and it works better...

Re: Opposed Piston Engine Project - The Steam Version

After finally having some time (besides legal fights with criminal troublemakers that is) and binge-watching Jay Leno, I'm still trying to figure out how I construct the intake manifold. I intend to split the cylinder liner into 2 parts which are obviously axially alligned and end on the opposing en...

Re: digital steam engine indicator

Exactly. I think an encoder would do the trick. I am still not sure how an reluctor works, but if it is the ignition timer thing I had in my car, I suspect it would be usable for rpm messuring, but not for a good diagram - at least as far as I understand magnetic reluctors. But rotary encoders seem ...

Re: Opposed Piston Engine Project - The Steam Version

I am currently fidling with different pieces of steel trying to figure out a way to attach the bearing end plates to the crank case tunnel. Does anyone have a good idea to do so? This is what I originally intended: https://i.postimg.cc/0jt63GkL/image.jpg (The piece of metal I used as the table is go...

Re: Opposed Piston Engine Project - The Steam Version

After the input of using a one-piece crankcase, I got trapped by the idea enough to just try it out. I feared the neccessity of entirely going overboard with the dimensioning of the crankcase, but actually, even the material I originally intended to use was just big enough for the crankshafts to be ...

Re: Opposed Piston Engine Project - The Steam Version

The idea with the one-piece crankcase definitely sounds like the sturdier solution. The only problem is that the crankshafts I am using have one-piece con rods, which I couldn't detach from the crankshaft. (Maybe that is why you are suggesting a bigger size of the crankcase - to have enough space to...
