=Description=

A heavy plate (1.0" thick) is used to provide a solid base for the steam engine and the crankshaft assemblies. This plate should be further attached to a massive sub-base, such as a concrete slab.

=Instructions=

Using 1.0" thick steel plate:

* Cut a rectangle 17" by 9.5" (exact dimensions are unimportant)
* Drill four holes to bolt the engine assembly to the plate:
** Each hole is drilled and tapped to receive a half inch bolt
** Space centers 6.5" by 8.5" apart.
* Drill four holes to bold the crankcase assembly to the plate:
** Each hole is drilled and tapped to receive a half inch bolt
** Space centers 2.0" by 8.0" apart.
** Offset the crankcase holes from the engine assembly by 4.6"

Alignment of the crankshaft assembly with the engine assembly has two critical points:

# Center line of engine and connector rod must be centered on the crank pin.
# Amount of steam let into the engine is determined by the crankshaft offset (4.6"), though this can be fixed by adjusting the length of the bump pins.
