There are many ways to attach your bumpers. A lot of it depends on the design of your chassis. Whatever you do, make sure you do the following:

1) Make them sturdy enough to survive playing defense through all of your tournaments, hopefully including Championship. Use good quality plywood, not dimensional lumber since it can crack along the grain.

2) If you are going to build a set of Red and a set of Blue bumpers, make sure that whatever method you use to attach the bumpers allows you to swap between them quickly. It would be great if no tools are needed. The fasteners must be easily accessible. The hardware must stand up to the rigors of gameplay without deforming and jamming.
