No idea about the Viking machines but any domestic machine as far as i am aware of will cope with a max. TEX70 (about 14wt.). I can confirm that works fine on the Singer 15-91 if i use the other bobbin case that has been pre-set for the heavier thread. This is what i'll use for Heavy Canvas projects

ps: personally haven't tried the TEX90
