Chamfering the holes is one of the details I latched onto while planning the bench. This makes it easier to get accessories into holes by slightly widening the mouth. It also helps prevent the hole from chipping out when you remove an accessory. The LVL is particularly prone to flaking so this was an important detail.
Here is the before shot of a typical hole, made with a 3/4" forstner bit in a drill press.

Sorry to be so stingy with the details on the bench design, but I will be adding more posts about my unique, new, and possibly foolish idea very soon!
