Over the years I've made quite a few rabbit runs, but this one is the best yet, It’s robust and can be easily assembled, disassembled and stored by one person. The one in my garden has 6 frames, so depending on how the garden is being used on a given day, the rabbits can have a big run (all 6) or a smaller one (using 4).
Hopefully the build will get published in a future edition of the Good Woodworking (the full article was accepted this morning). Given I have the tools I jointed using domino and pocket screws :-)
The 'clever bit' is the use of screw eyes (45x4.3mm) at each end of each frame, positioned 160mm from the top at one end and 170mm from the top at the other end (and vice versa for the bottom). This means any frame can join any other using the connecting rods. The shape can be changed, a rod can be removed to allow easy access etc. If the rabbits play hard to get, you can move the frame into a triangle to catch them. If the run is not needed (e.g. winter or cutting the grass) all the frames can be stored flat.
I attached the mesh with an excellent narrow gauge staple gun (Sacrofast) that I bought new from ebay last year - it takes up to 40mm staples, I use 19mm for this. You can get cheaper silverline guns for under £30
