In the above example the correction would be to place a 35 mil (35 x
0.001") shim under foot "b" (the foot with the largest gap)—just like
placing a beer-mat under a wobbly bar table!
Angular soft foot
If one value is significantly higher than the others, then angular soft
foot can be suspected:
.
The "problem foot" or machine frame is probably bent or distorted in
some way. In this case loosen the bolt and examine the foot more
closely. Use a feeler gauge to establish the variation of the gap and
use these measurements to sketch the shape and dimensions for a
stepped shim.
If the soft foot is purely "angular," then the stepped shim will vary in
thickness from about zero to twice the displayed ROTALIGN value.
