This step by step tutorial of How To Build An Amazing Garden Trellis Obelisk that is a vertical support structure for flowering
Garden obelisk
You will need:
- 4 x 1.8m x 45mm x 45mm treated pine (legs for frame)
- 8.6m x 45mm x 19mm treated pine (for step 2, cut lengths of 2 x 610mm, 2 x 520mm, 2 x 415mm, 2 x 310mm and 2 x 220mm; for step 6, cut lengths of 2 x 650mm, 2 x 550mm, 2 x 440mm, 2 x 330mm and 2 x 220mm)
- 16.8m of 12mm x 12mm treated pine (cut into 12 x 1.4m lengths)
- 1 x 200mm x 240mm piece of treated pine
- Fence post top
- Power saw (or handsaw)
- Drill
- 40mm galvanised nails
- 45mm galvanised screws
- 25mm panel pins
- Hammer
- Tape measure
- Pencil
- Exterior paint
1. Lay two of the legs in an open-ended V, with the base of the legs 650mm apart and the top 200mm apart (measuring from outside edges).
2. Use the first set of 45mm x 19mm cut lengths and place them on the V frame, as shown, spaced at even distances, and at a point where they slightly overhang the edges.
3. Using a pencil, mark the angle on the underside of each supporting piece where the wood needs to be cut to line up with the frame. Remove from frame and cut with saw.
4. Nail support pieces to frame, using two nails per end. Repeat for the other two legs, laying down another V frame and attaching the supports.
5. Lay the two frames upright on their sides. Measure and set the bottom legs 650mm apart and the top 200mm apart (measuring from outside edges).
6. Place second set of 45mm x 19mm cut lengths on the frame in line with other supports. Mark cutting angle, cut and nail.
7. Drill a pilot hole in the centre of the 200mm x 240mm piece of wood. Screw the piece of wood to the fence post top. Screw to the top of the frame.
8. Nail three lengths of 12mm x 12mm pine to each side of the frame using the panel pins. Finish off by applying two or three coats of paint.
