Has anyone ever used a product for measuring and marking cuts, called a Mingo. It looks interesting, but I would like to hear some opinions before I spend the money. I am concerned about getting my wood to fit the small box on my soon to be installed Tribute. (small box) My thinking is that I will need to take advantage of every inch of space to get the best and longest burn, but if it won't fit in the stove it does me no good. I'm not that good at judging length while I'm cutting. I think I need something to measure my cuts, but what? any ideas?
