Attach the side slats to the leg by pre-drilling 4mm clearance holes 35mm in from each end. Position the top slat over the leg with an overhang of 20mm and flush at the top of the leg. Drill a 3mm pilot hole into the leg and fix in position with two screws per slat. Attach the middle and lower slats with a space of 18mm.
Tip: An 18mm wide scrap makes the perfect spacer. Repeat this process for both side panels.
Attach a bottom slat support to two of the end slats. This is done by first pre-drilling a 4mm clearance hole through the slat. Drill a 3mm pilot hole before attaching with two screws. Ensure the slat support is flush with the bottom edge of the slat and positioned centrally.
With the end frames turned upside down, attach the top end slat followed by the middle then finally the bottom slat. Note the position of the bottom slat support. The spacing can be simply maintained by aligning the edges with those of the side slats. Remember this is rough sawn hardwood so close enough will be good enough in this case.
The bottom slats can be placed in position, it is not necessary to screw these in place but be sure to space them evenly to allow for drainage.
Use galvanised exterior universal screws to add to the rustic look or a screw designed for interior use and allow the natural rusting process take place.
To reduce splinters from the dry old hardwood, use the multi tool by One+ to remove all the sharp edges. Don’t go overboard with the sanding, just limit it to the sharp edges and corners otherwise you may lose the rustic appeal.
Your box is now ready for your choice of anything, like herbs or flowers or just simple storage!
Now you can grow your own rosemary, climbing beans, oregano or whatever your taste buds desire. The beauty of this project is there are no rules, if it looks right, it probably is right. The size can also be altered to suit your requirements. Rough sawn hardwood will vary in thickness and may have splits, cracks or nail holes but that simply adds to the rustic look.
