Manuals are available for Jakobsen Grinders
Founded in 1942, the Danish Jakobsen Company are best known for their range of high-quality surface grinders. For many decades the most popular and widely sold were the conventional Types SJ12, SJ16, SJ24 and SJ25 while in modern times automatic and computer-controlled models have been introduced which, by the 1990s, included the SJ618, SJ824, SJ1032, SJ1424, SJ1432, SJ5025 and the SJ6025.
Unfortunately the little Jakobsen tool & Cutter grinder shown below is little known and technical information scarce - should any reader be able to help with details the writer would be most interested to hear from you.
