I have a Kity 613 bandsaw which i have owned from new, maybe 7-8 yrs and i keep having trouble getting straight cuts when ripping timber. I don't use it very often but when i do i often spend ages getting it all set up only for the cut to wander badly. I am using 1" 3tpi blades and go to great lengths to get it running right only to be disappointed and i am on the verge of selling it. Has anyone got any ideas before i do, i know it's a good saw but have run out of ideas unless it is the blades themselves letting it down. Can anyone help. Regards Andy (from the UK).
