You can DIY a very good bus for a fraction of the cost of a store-bought bus. The only critical part is a piece of copper flat bar big enough to handle all the loads. I used a 1" x 1/4" bar,IIRC. I chose to tap the holes and use SS fasteners (don't want them coming loose). The bars are mounted in conventional 4" plastic waterproof boxes available at the big box stores. I chose to glue and screw in standoffs for the bus bars inside the boxes (HDPE). You can use your own creativity on how they are secured in the box (or not secure them at all).
