Be warned that you need to use a strong adhesive to connect the bushing or it will fail. I used 2P-10 (a type of wood super glue) and it failed after about a week). I had to break it down and redo it. The second time I used a $2 two part epoxy from Harbor Freight. This seems to be holding well.
Note: 2P-10 is amazing for holding wood parts together when assembling. It is not cheap, but holds wood great and sets in seconds.
