i have two bots of wood with nails in and bent over the metal frame. works a treat for 3 years
I also turned the legs round on the reel. It never falls over now but every now and then I catch my nuckles on the ground. Arrrrghh
I use these http://www.caravangroup.co.uk/product_desc.php?id=5042 to hold the reel to a square of plywood
