When I bought my Delta 14" bandsaw a few years ago, I got a free riser block in the deal. The riser has been sitting to the side since I didn't really know how or if it would help. The more I read these days about resawing, I see people mentioning this accessory. So... I was wondering if anyone had opinions on whether this is a good update for my saw. Once you install it do you leave it on or is it just for specific uses? Pardon my simple questions :-? .
