Some notes from Julian and Elise:
Purchase materials. Our cliplock came 420mm high by 8200mm lengths (cost around $2.50 per metre second hand). I decided to make our beds 6000x1200. I also purchased 800mm lengths of 12mm reinforcement rods (cost around $1.20 each), self drilling hex head screws and a 12.5mm drill bit.
Tip: In hindsight, 6000x1000 would probably have been better. I got greedy with the width to get extra growing space but it is a bit uncomfortable reaching into the middle. Hopefully when the soil is full it won’t be as much of an issue.
Important! The cliplock has different edges along the lengths, one short and one long. For each bed make sure you mark out opposite ends for the two sheets (ie one left, one right) otherwise you end up with different edges along the top of the bed when you want the same edge around the whole bed!!! 1) Cut the sheet and the ridges where marked using an angle grinder with a cutting disc. I found thinner discs easier than thicker.
Drill holes in the ridges for the reo rod. Do the top ridge, hammer the reo through then do the second, repeat. I used two rods on each side so divided the length in two (3000mm) then again (1500mm). So one rod at 0.25xlength and another at 0.75xlength.
Many thanks to Julian and Elise for this assistance.
Len's added suggestion app' 1" PVC pipe could be used to cover sharp edges, or use some PVC angle to tie to the corners, even say maybe 2" PVC cut down the middle. The edges did not cause us any issues, but being proactive is always better especially if there children about. These beds can be fitted in as best as! We generally put them 500mm apart to allow for walking at least, then mulch the paths with newspaper tucked in under the edge of the new garden and cover with mulch hay, sawdust (good snail deterant) or smooth rock chip (bit harder on the feet), teh pathways which could go all round then act as weed barriers. this path/weed barriers then become habitat for the garden goodies
