View Full Version : Tripod table legs, based on burr puzzle

I've been trying to come up with a way of building a set of table legs based on a 3 burr puzzle. This would allow easy construction, a no glue assembly, and look pretty cool. A European company, Praktrik (https://praktrik.com/1x3) has done just this with their 1x3 table. The 3 legs are identical and easy to cut. The problem is that the ratio of the tripod diameter to table height is really limiting in that there is (very) roughly a 1.5 ratio between diameter to height. For an 18" table, the maximum height is around 9" unless you want the legs sticking out. The root cause is that the legs join at 90 degrees resulting in a 45 degree angle.

The simple solution is join at a steeper angle. Unfortunately, the geometry becomes somewhat daunting. I mocked up the 90 degree version in fusion360 but I'm struggling with a steeper angles. Anyone see table legs such as this or can point me to a design that worked out the geometry?

I've attached images of the assembled legs and the unit they are built from.
