I have just begin the the construction of the Vintage steam engine!
  This paper is apox 100# grade, it is quite different to work with than the tiny lighted church kit I built, I decided to start with the sand/turbine as it is totally hidden from view and only needs to be structural sound, not pretty so a good place to get familiar with the heavy paper.
  The very old art is hand drawn and not nearly as precision as a modern kit, but still fun to work with, between the model errors and the difficulty getting the second side centered with the first, (my errors) my turbine is strong but spun with side to side run out aprox .050 although functional, this will never do for a Toolmaker so I simply opened up the axle holes with a needle file and added glue reinforcement square, but spent a little effort on better centering.
  The artwork on this part of the model is only to help locate the vanes as you build.

I was concerned my 2.32 PSI aquarium pump is very low air volume output but much to my satisfaction my trued up paper turbine spools up nicely on the low volume output, this will be considerably cleaner to run than sand!
  The Turbine test stand is just a scrap of 100# paper folded in a U shape and a bit of pencil lead in the notches for lube. The test axle is sewing needle.
