New Jaws for Bench Vise Made From an Old File

[Toolmaker51]

Some forums are elitist; you'll get flack occasionally responding to something 4-5 even 10 years past.
Those clowns think they know everything (including other solutions) worthwhile? We've all seen examples, guys who can't figure out a bandsaw fence or height gauge scriber clamp.......
Meanwhile, here at HMT.net and this instant 26 folks are viewing this 'old' thread and picking up at least 4 bits of useful info. There is very little that isn't evolving around DIY, but choosing old versus new doesn't have to be a guess.
