Its beginning to get a little crowded with a support every 5-6 tiles. I applaud the animation, and agree that they are a good idea, but currently to avoid a cave-in, there is a lot of overlap and overcrowding.
Some ideas include:
increasing the radius of safety to approach or mirror beehive radius
reducing the materials needed from 20 blocks 2 nuggets to 12 blocks 2 nuggets so that it can be constructed with one tree log
