Now consider those really wide boards you can’t bear to rip into narrower pieces. Jointer fences are short, which doesn’t provide much vertical support for a board that’s 10" or more wide. How do you know the face is snug against the fence when a wide board is on edge and you’re guiding it by hand? It’s hard to be sure. I worked through this challenge by using four interlocking riser blocks included in Magswitch’s Vertical Featherboard kit to create a taller featherboard. When double-stacked, they position the top featherboard in line with the top of the jointer fence. It’s ideal for this job.
