-jigsaw or regular saw
-cable wire or can use a chain or string
-optional foam tape to hide screws
Step 1: Cutting the Wooden Frame Strips
After cutting the strips to equal lengths with either a jigsaw or saw, sand the hell out of it to get it super smooth to avoid any nasty splinters.
Step 2: Cut or Find Some Galavanised Steel or Magnetic Metal You Wish.
Either punch or drill clearance holes around the perimeter of the metal sheets keeping within the thickness of your wood. These holes will act as your clearance and hold the metal, once screwed to the frame, giving it strength and keeping it neat.
Step 3: Making the Wooden Tray to Hold Pens and Brushes Etc and Fixing It to the Frame
Once you are happy with your trays drill 2 more clearance holes that will be used to screw the tray to the frame, be careful again as not to split the wood when screwdriving it into place.
Cover the screws with foam or any tale if you wish.
Step 4: Screwing the Frame
Step 5: Attach Hinge to Top of Both Frames
Screw the hinges onto 1 frame first then line the other panel up next to it in postition to get the exact same place to fix the other side of the hinge. That is critical or it will be wonky.
Step 6: Wire Guard and Velcro Strap
Attach A velcro strap near the bottom which will hold legs in place when in storage position.
