Take your length of 184 x 19mm Pine and cut two lengths at 100mm and two lengths 250mm. The shorter lengths will be our drill dividers, and the longer lengths will be the charging stations side panels.
Next take your length of 42 x 19mm Pine and cut four lengths at 200mm. These will be used to hang your drill in position. Use a small container as a guide to mark semi-circles at one end of your four hangers. Use a jigsaw to cut along the marked lines.
Clamp all four of the hangers together and use an orbital sander to even out the cuts. At the midline of your hangers, mark and drill two 4mm mounting holes. You should place these holes around 70mm from either end.
Apply glue to your two dividers and two side pieces, then position all four of them on top of the four hangers. Clamp them in position. Using the previous holes as a guide, drill into the dividers and side pieces with your 4mm drill. Join the hangers to the dividers and end pieces with your screws.
Measure and cut a piece of 184 x 19mm Pine to 240mm. This will be our joining piece, which ties everything together. Mark the timber at 68mm, 87mm, 155mm and 174mm. Mark and pre-drill two 4mm holes approximated 80mm from the outside edge in between the 19mm sections you marked out. Place this joining piece on top of the two dividers aligning them inside the marked lines. Using the previous holes as a guide, drill through the joining piece into the top of the dividers. Apply glue to the two dividers and place the joining piece on top of them. Fix the dividers to the joining piece with your screws.
Position the side panels up against the joining piece. Mark on the sides above and below the joining piece. Drill two 4mm holes through the side panels approximately 70mm in from the outside edges. Temporarily clamp the side pieces in place and drill through them into the horizontal piece. Remove the clamp and apply glue to the end of the horizontal joiner. Reposition the side pieces and fix them in place with your screws.
Take your length of 42 x 19mm Pine and cut one length at 240mm. Place this trim piece on the horizontal joiner and between your two side panels. Pre-drill two holes on both sides through the side panels and into the trim piece. Remove the trim piece and apply glue to both ends and along the bottom. Reinsert the trim piece and fix it in position with two screws on both sides.
Take your length of 184 x 19mm Pine and cut one length of 240mm. Apply glue to both cut ends and insert it in between the two side panels and behind the trim piece. Position this shelf at an approximate 45-degree angle. Pre-drill two holes on both sides through the side panels and into the shelf. Fix the shelf in position with two screws on both sides.
Use your timber putty to fill any obvious gaps between pieces and your screw heads. Once the putty has dried, use your hand sander and 120 grit sandpaper to smooth the filled areas. Lightly run over any timber corners with the sander, so they are not as sharp.
Take your length of 42 x 19mm Pine and cut one length at 240mm. Use a small container as a guide to mark a quarter circle on two corners. Use your jigsaw to cut along the marked lines. Mark seven locations along the piece of timber. The first location is in the middle at 120mm, and the rest are spaced out 30mm from each other. Place some tape on your 6mm drill bit 15mm from the tip. Drill into your seven locations 15mm deep. Pre-drill two mounting holes through the timber's side 50mm in from each edge with your 4mm drill bit. Make sure these holes are between the holes drilled previously. Countersink those holes on the same side as you cut the profiled corners with a 6mm drill bit to a depth of 20mm. Apply glue to the opposite side and fix the bit holder onto your charging station's front face just below the trim piece and above where the drills are stored.
Apply a couple of coats of varnish to the charging station and then attach mounting brackets. I've used L brackets as I fixed this unit to timber battens.
You've now completed your drill charging station. The shelf conveniently stores your charger and spare battery, drill bits are easily accessible, and you have storage for up to three drills. Because of the simple design, you can alter the lengths to suit any number of drills.
