Theres a buddy of mine hasnt spent a dime on fire wood in years , he collects untreated pallets from local business during the summer months , cuts them with a circular saw and stores them up for winter . He tipped me off to a factory who tossed out a load of screws bolts washers nuts and rivets , almost 40kg of it , mainly zinc plated ,but some stainless too , M3 upto about M12 ,all mixed up . In only an hour or two Ive sorted most of it into Linbins . Once its rinsed down and allowed to dry , then a quick spray of WD 40 , its all as good as new . Must be a couple of hundred euros worth of fixings , I wont need to visit the hardware store for a while .
