Being just a weekender in this, I question the value of biscuits being used in a rub joint. I see the use of 2 or 3 when assembling a glue up as helpful, but not adding any strength to the actual joint. On the other hand, where you are dealing with end grain in situations like picture frames or butter boards on tables, the biscuit acts like a splice of sorts. The problem I see, is that the biscuits tend to be loose in the slots, and the swelling of the biscuit as it absorbs the glue could cause some misalignment if the glue is not disbursed evenly in the slot. Am I even close on this?
