Multiple cauls will be used to to support sheet plywood above the bench to cut them using a track saw. The cauls may be various lengths and will have pegs that locate them into the bench. For the pegs (in the cauls) to line up at different locations, the hole spacing must be as accurate as possible, and repeatable. The cauls will be removed when not using and stored so the bench can be used as a normal bench... or individual dogs or clamps can be added as necessary when needed. If the bench used just individual dogs the accuracy probably wouldn't matter, but since the cauls (long boards with pegs) are used... it would be nice to have the pegs align wherever needed on the bench and not only to the two holes that happen to line up.
Woodworking is like wetting myself...Only I know that warm feeling!
