Self cantering spring loaded punch is a great little tool to get the holes lined up perfectly. A trim/laminate router makes short work of rabbiting in a slot for the smaller hinges. For doors I have a 3 slot aluminum jig tool. For removing and putting doors back on a small wedge is handy. For holding doors to work on them I have a jig, A 2×6 laid on the floor with a couple of pieces of 3/4 plywood screwed to the edge a couple inches apart pointing up from the floor.
