'''Prototype 1 Design Elements:'''
 
* Cylinder
* Piston Assembly
* Bump Valve Assembly
* Oil Sprayer
* Crankshaft
 
Later designs could include an oil separator on output, quick connectors for steam input and exhaust, oil-less design, etc.

For analysis and dimension purposes, the following are defined:
 
{|
|-
!Variable
!Exlanation
|-
| Clen
| Interior length of the cylinder.
|-
| Cdia
| Interior diameter of the cylinder (or perhaps the sleeve).
|-
| Coff
| Distance from the end of cylinder to the center of the crankshaft.
|-
| Ptrav
| Total distance the piston travels.
|-
| Pstrt
| Piston starting point (bump valve fully open).
|-
| Pmid
| Piston mid-point.  Max crankshaft offset.
|-
| Pend
| Piston end point.
|-
| Prod
| Piston rod length.
|-
| Soff
| Crankshaft offset.
|-
|}
 
Questions to be answered given the geometry:
 
* How long does the piston rod (Prod) have to be?
* Given a Cdia, how long is Coff to clear the end of the cylinder?
