KLO Posted July 17, 2018 Share Posted July 17, 2018 to double the time of total use, maybe try cover it with a soft tin or cheap sheet metal and whenever the sheet metal wears out just replace it or throw back into the scrap heap to use on another project. brass or tin are a good choice but not copper as it is a bit expensive. but I just use at the moment a stick and a slab of wood or a chunk of rolled up sheet metal heated up until it sits flush will also work.
