I was reading Zach's post on oil for preventing rust and I thought I should update this post.
Watch out for vegetable oil which dries out.... I went to the chain mortiser yesterday and the oil I've been using had stuck the machine, took a good hard push to make it slide up and down again. And I've had trouble with electic chainsaw also.... am now back to using hydraulic fluid, which actually only shows temporarily on the wood.
Does anyone have experience with veggie oil and what kind will not dry out??? olive?
