Castle Tower

 
Material
  • Used truck tyres x 9
  • Vinyl - stone or brick style 4 x 2.5 m2
  • Outdoor carpet 2 x 2 m2
  • Perm-a-pole 100 mm x 3 m
  • Rapid set concrete bag x 2 (or more)
  • Royal looking material
  • Old mop pole
  • PVC pipe
  • Aluminium blind track 
  • Strapping
  • Wood tech screws
  • Screws
  • Scrap treated building pine timber
  • Marine ply 1200 mm x 1200 mm
  • Sand / land fill
  • Small flat black plastic for the fake window
  • Vinyl glue
  • Shield
  • Double sided tape (strong outdoor)
Procedure
  • Foundation
  1. Prepare a level paved area with a deep hole in the centre.
  • Tyre Preparation
  1. Drill numerous large gauge holes in the bottom surface of the tyres to allow any water to drain.  If water builds up it will create a breading ground of mosquitoes.
  • Tower
  1. Stack the tyres on top of each other.
  2. Screw strapping to the sides as tyres are added to avoid them moving out of place or toppling.
  3. Once all the tyres have been added feed the perm-a-pole down inside the stack and into the hole in the ground.
  4. Pour in the bags of concrete dry then add water by pouring inside using a hose.
  5. Once the concrete has set, fill the inside of the tyres with sand.  I filled up to the top of the forth tyre.
  • Roof Base
  1. Mark the centre of the 1200 mm x 1200 mm marine ply.
  2. Use a string and pencil to swing and mark a circle 600 mm radius, and a smaller 200 mm radius circle.
  3. Jig saw out the circles.
  4. The central small hole is to allow the perm-a-pole to protrude out.  The pole is likely not to be reliably central to build the roof off.
  5. Build a timber bridge over the perm-a-pole.
  6. Attach a shaft of PVC piping to the centre.  This is to hold the flag pole later.
  7. Attach down the marine ply to the tyres and perm-a-pole using a length of aluminium rail.
  • Roof Structure 
  1. Create a structure to hold out the sides of the outdoor carpet roofing, a bit like an umbrella structure.  I used more aluminium rail.
  • Roof Covering
  1. Cut out a 1 m radius circle of outdoor carpet.
  2. Cut one slit from the outside of the circle to the centre.
  3. Fold the carpet around the roof evenly, with the flaps over lapping.
  4. Cut flaps of about 10 cm around the edge of the carpet to be folded under the marine ply.
  5. Screw the flaps underneath on one corner of the flap so that all flaps are overlapping.
  • Flag
  1. Sew a flag with a V shape cut on the end.
  2. Attach the flag to a pole; I used an old mop handle.
  3. Feed into the PVC pipe on top of the roof.
  4. I spray painted gold a wider gauge PVC length of piping and fed over the plain PVC piping for effect.
  • Vinyl
  1. Cut the vinyl to the height of the tower (2.3 m in my case), and enough to wrap around the tyres and overlap (3.5 m in my case).
  2. Attach the vinyl by screwing on metal strapping.  I did this down one side and around the top at the back, out of view.
  • Shield and fake window
  1. I made a fake window out of left over vinyl, a flat piece of black plastic, and vinyl glue.  I used double sided tape to attach to the tower. 
  2. The shield was purchased from a toy store and attached to the tower using double sided tape.
