After having added an official riser block, I realized the best thing they offer is on the guard side, which the block of wood riser doesn't. Otherwise the block of wood could be a fine spacer, to be a riser. Me personally I like having the longer guard/blade shield. I suppose guys like Kenny, or Jim who can also do a lot of perfect metal work could roll their own guard. I don't do that well with metal myself, so a set up like I have works best for me. If made incorrectly I can see a lot more issues then just being a bit wonky. But I do like my guards, and use them on all cuts where I can.
