Thinking of building a flame licker. I understand that they can be "difficult" to function. I assume that means bore and stroke must be in proper proportion,...among other things. I like the little Poppin plans that are readily available but I cringe when I see 2-56 tapped holes. Not only do they scare me, but the taps are damned expensive.
I can see that increasing the stoke by a factor of say 1.5 would not equate to increasing the bore diameter likewise. Perhaps I could increase the bore "area" by 1.5? I don't know.
In lieu of scaling the Poppin, does anyone know of other vacuum engines on a larger scale?
TIA
