The answer to most problems in the workshop is to develop a jig that avoids you having to do things more than once and to unify some aspects of the construction. An alignment box jig is a perfect solution for drilling accurate holes in mating components without having to mark out twice. The only critical factor is that it is square at one corner, the dimensions are up to you.
STEPS 1-3I used biscuits to make my box but screws would be quite acceptable. When you're satisfied with the box select the best corner and plant a small fence along two edges. Ignore the outside edge of the box and concentrate on making sure the inside face of the two fences are square with the corner edge of the box and therefore in line.
I like to work 'off centres' whenever I can whether it be in the workshop or on site as this seems to be the most reliable and convenient datum for any number of measurements. Every component has a centre in two axes and once established it can be used to simplify cutting, drilling and location.
STEPS 4-5On the underneath of the rack begin by marking centres for the uprights - dividers - in this case 30mm apart. Extend the lines down both edges and number each line. Take one of the dividers and with a marking gauge place a line clearly off centre on the bottom edge then replicate this line from the other face. It should now be simple to find the centre of the piece by eye by positioning the gauge point in the middle of the two marks. Just tap the rod of the gauge on the bench to make tiny adjustments without having to use a ruler. Extend the mark a short way along both sides.
At this point you will notice that we are still working with the dividers at the same width as the base board. Without a pillar drill screwing into end grain can prove tricky but fortunately we have our alignment box jig to get round this.
