For our kitchen cabinets, I wanted movable shelves, and using the Domino to cut shelf pin holes seemed like a natural idea. I cut two lengths of plywood, and attached a strip on the end that let me set the plywood up against the side to give me 90°. Both pieces were the same thickness, the spacing I wanted for my shelves.
Then I just clamped them to the board, cut my pins, moved one guide past the other, and repeated the process. Poof, instant shelf pins!
This was inspired by Charles Wilson's use of Domino pins for the bookshelf
