Now, go around to the fly wheel and place the straight end of the
tram at same point on the block, and with the hook end make a mark
across the crown or center of face of fly wheel; now turn your engine
past the center and on to the point at which the line on cross head is
exactly in line with the lines on guides. Now, place your tram in the
same place as before, and make another mark across the crown of fly
wheel. By the use of dividers find the exact center between the two
marks made on fly wheel; mark this point with a center punch. Now,
bring the fly wheel to the point at which the tram, when placed at its
proper place on block, the hook end, or point, will touch this punch
mark, and you will have one of the exact dead centers.
Now, turn the engine over till it nears the other center, and proceed
exactly as before, remembering always to place the straight end of tram
exactly in same place in block, and you will find both dead centers as
accurately as if you had all the fine tools of an engine builder.
You are now ready to proceed with the setting of your valve, and as you
have both dead centers to work from you ought to be able to do it, as
you do not have to depend on your eye to find them, and by the use of
the tram You turn your engine to exactly the same point every time you
wish to get a center.
