My head is swimming with all the information I learned from Linotype University, even though I could only make it for 3 short days (the entire workshop lasts for 7 days). We worked mainly on 3 Merganthaler Model 31 Linotypes, but we also learned how to cast type with a Ludlow, how to cast new composition rollers, and finally printed our cast type on a few various presses. I had a great time and will put this new knowledge to work at the Homestead Historic Print Shop, at least until it gets too cold to work in the barn. While I sort through all this information, you can see the photos
here.
Linotype University is held each fall in Denmark, Iowa, at the Working Linotype Museum. I highly recommend it.
If you're not sure what a linotype is or how one works, Metal Type has posted
this instructional documentary filmed in 1960 (shown in two parts).
