Oh haha, by "Guaranteed to have what you need" what I meant was "Will have every other knob on the planet except the one you need." Sorry.
Research "threaded studs", along with knobs. Also search "gear lever handles." Thank God for paper catalogues!I bought a drill press a few months ago that was missing one of the handles. I’ve searched McMaster car without success. Any other ideas where I can find a 7/16-14 threaded rod with knob handle?
