I made this sculpture based on the small maquette below to see if it would work. Then I cut large timbers of eastern red cedar freehand on a bandsaw. The pieces are attached with very long structural timber screws. The next step will be mounting it on a round concrete pad.
This is an abstract wood sculpture sitting on my table, still in progress. I cut cedar timber freehand on a bandsaw and then assembled it using structural self drilling lag screws. It is pretty much finished, I think. The next step is figuring out how to put it on a concrete base and install it outside so it doesn’t tip over. That’s the plan, anyway.
