How about looking at the laser lines for homes. I have a level with a
split cross or line out of the end. That should shoot a nice reference
line and a card (4x5 card or sheet of paper...) can be used to set a reference
and then checked on the far side.

BENEFITS OF GOOD MACHINERY ALIGNMENT

My sawmill is powered by a 5.5HP gas engine turning a 3/4" extension
shaft through a Lovejoy L095 coupler. The shaft is supported by 2
pillow blocks on a welded frame that didn't turn out exactly right
after milling the tops flat. I shimmed the further block so that the
two shafts aligned to a straightedge, then the nearer block to make
the abutting ends align, but it isn't perfect and the first black
rubber spider tore up, either from angular or radial misalignment or
from heavy starting and stopping shocks before I got the loose-vee-
belt clutch working right.

Now that it's all assembled, how do I recheck alignment of the short
engine shaft to the longer extension without disturbing the coupler
and the pillow blocks? I was thinking of 1-2-3 blocks and a
straightedge, or is there a better way? Audel's "Millrights and
Mechanics Guide" isn't very helpful.

Also, how do you align vee-belt pulleys with cast outside surfaces
that don't run true and are too big to clean up in a lathe?
