Last summer, we prototyped a picket fence design, using traditional power and hand tools. Over the past year, we have done some renovation in the back yard, including having the landscapers take out the old fence and put in new fence posts. We left the fence itself as a family project to do over the course of another year or two.
The prospect of shaping the folded circular design from the prototype on the top of about 500 cedar fence pickets was enough to convince me we needed some automation to help. I must admit it didn't take a lot to convince me that what we really ought to do was build a CNC router. Of course the kids are not driving this project, but I have tried to involve them at every stage. I hope that it continues to provide them with an engaging way to explore software and machines.
