One of the minor hassles to using a hand-held router is that you have to wait for the bit to stop spinning before setting the router down. My solution to the problem was to make a simple router stand that allows me to save this wasted time.
I do not recall how, or when, I became curious about what I call the double-twisted dovetail. My interest was probably aroused by a discussion that centered on dovetailing in two directions at once, e.g., a drawer side to a front. For a long time I simply dismissed it as unworkable, without thinking it through. I was thinking idly about it one day, and realized that the joint was probably feasible.
Most shop floors are uneven. So whenever I build a shop-made tool stand, I allow for some handy leg levelers. They add about 2 inches to the height of the stand.
