My dumbells are home made (apart from the 40s and 90s),i made some of them from old fire extinguishers,cut them to size with a grinder,welded checker plate on the ends and filled with scrap steel.A coat of paint to finish them off.They go from 20 to 110 in 5lb jumps.I`m making a pair of 120s and 130s at the moment.The dumbell rack is made from a n old pine bed and some scrap wood i found.The barbell on the floor is made from a gas bottle filled with concrete,it weighs 65kg.
