Wow that drew a rousing response. Let me put the question another way: How many of the readers of this forum have had to align an enlarger? Was It easy? Or was it hard bordering on impossible. How many hours did it take to align? What model enlarger & what alignment equipment were used?
For the 2nd part How long in terms hours of use did it stay in alignment? I'm sure no one kept exact records of the times, just your best guess.
This information would be of great use to me & I suspect many others.
Thank you, Jay Drew
