Either you use jigs or you tie them together temporarily and cut the stack.

Yup. If you're doing almost anything in wood, a set of clamps is more useful than you'd think.

I made a table. The legs are all exactly the same length, but don't ask me what that exact length is - I eyeballed the height I wanted and then clamped all the legs together before cutting them.

Another tip for building things with legs - a 3-legged object is stable on any uneven surface while a 4-legged objects will wobble on uneven surfaces.

This is because 3 points make a plane, adding a 4th point that is not on that plane introduces a wobble.

  • Easiest way to avoid that wobble: get the legs to within 1 mm, add felt pad to the bottom of the legs. The pressure of the table will compress the felt and all four legs now contact the ground.

      On a level floor, sure. But for something that will be on uneven surfaces, like outside, 3 legs are stable, even if the legs are all different sizes[1].

      [1] Three points make a plane, the plane itself may not be level, but because all points of contact are on the same plane there is no wobble. When there are more than 3 legs, some points may not be on the same plane, producing a wobble.

pretty amazing how the simplest of solutions seems to be so elusive. i've been guilty on more than one occassion of making something seemingly simple as difficult as wrangling cats.

  • It's just experience. Everything you've done before or that you've seen done by people that knew what they were doing is trivial, everything you haven't done before is difficult.
