I am working on a railroad rail to make a small anvil for copper jewelry. Which is more efficient:  a 4-inch side grinder or a 7-inch disc grinder using 36 grid?  The 7-inch seems to have more sparks

Ok I soon will be able to retire and working on my tools.  I have plans for a treadle  hammer that calls for two (2) head spring 1/4x3x17 plate leaf.   If I Google "plate leaf" I get dinner plates.  If I Google spring steel I get all these different grades.   What do I need and where do I get it?  Newbie in Charleston, SC
