Working on making corner supports is not as easy as first thought!
Firstly you need to work out how big the support has to be and then where the holes have to go in the side of the module so you can drill the screws into the side of the frame and through into the support.
You need to work out the size of support, then I used 45x45mm pine and at 45 degrees each end cut them all to the same sizing for all 32 corners of the modules
I made up a template to sit on the side of the frame to keep everything uniform and less marking out and mucking about.
Firstly the Leggz bolt type end has to be hit into the timber with a hammer, but you have to first drill a hole for the shaft of the bolt end approx 9mm (for the size I used) then another hole within the last one which is for the leg bolt that pops out the top of the leg. Approx 7mm so we need it to be around 8mm so that it doesn't try and screw into the corner support,
Hope this makes sense!
