Not difficult, this will save you some time. Each hole needs to be a MINIMUM of 2 3/4 inch square. That will fit the largest diameter can I had in stock. For this I tilted the flats 8 degrees, we tried a few different mock ups and this seemed to do well. All this seemed like a good idea until I had to make the jig. Once the jig was made and TS set up I made real sure we had cut enough pieces plus two just in case. Lost a extra row but I wanted them to lay towards the back and not fall out if it got bumped. Seems to work well he shook the unit pretty hard and nothing fell.
