Bench Model

This is the final bench model. It does not include holes for the inductive charging units, or holes for the pipes. It also does not include the canopy. It is used to get a rough estimate of how much wood you will need to buy in order to build it. It can also be used to figure out how much your bench will weigh based on the material you use.

Overview Drawing of the Bench

This drawing shows the top, bottom, and side views of the bench, along with some external measurements.

External Cuts Diagram

This drawing shows many of the cuts needed to build the bench.
