CONSTRUCTING THE FRAME: The frame is constructed to fit over the top of the wheelbarrow.
The frame is four pieces of the larger wood lengths. Two lengths match the width of the wheelbarrow and two matches the length of the wheelbarrow.
NB: Make sure the body of the wheelbarrow is square.
The one pictured is slightly wider at the top than at the bottom. Make adjustments to the layout of the frame appropriately.
CONSTRUCTING THE CYLINDER: The cylinder is three bicycle rims with the spokes removed and they are then fastened to the batons.
You CAN remove the spokes with a pair of wire cutters, pliers or a screwdriver but do it with an angle grinder; it is so much more fun. Spokes are under tension and the first few will “ping” as the tension is broken. With an angle grinder.
Attaching the bicycle rims to the batons
Two of the three bicycle rims are attached with screws. The third is purposely not attached so that it can be adjusted once the castors are attached.
The castors are held in place with four screws. Because the spacing of the castors and the bicycle rims may need adjusting, hold the castors in with only one or two screws before final positioning of the cylinder is finished.
This bit is a bit fiddly. The third rim should only be attached once the correct adjustments for fitting the castors into the first and third rim.
Cut the wire used to sift the compost to length. It should be slightly larger than the circumference of the bicycle rims. Then it can be rolled up and fed down the centre of the cylinder. Unwind the wire inside the cylinder and attach it to the batons using the plastic ties. The fun of this is that these are the one-way plastic ties. There’s no coming back from this.
NOTE: There are two rolls of wire attached to the cylinder. The wire turned out to be about 30mm short, which required cutting and attaching the second roll of wire. Once the correct sized wire is attached, you should have something that looks like this
Which produces this BEAUTIFUL black gold. Or worm compost if you’re slightly less excitable.
