[SEL] Patterns #5

[George Best]

Rick,

Here's the shrinkage amount for various types of metal.

Iron - 1/8" per foot
Steel - 1/4" per foot
Aluminum - 5/32" per foot
Brass - 3/16" per foot 

Whether you take into count the shrinkage on a part depends on how
accurate you want to make the part to the original size.  On small parts
you may not notice the difference.

WAIT George
