Grinding Wheel Dresser
Inherited an old Sears 6 x 3/4 bench grinder - 36 & 60 grit - wheels are glazed and not true.
Bought a Harbor Freight star-point dresser ($3 bucks) and wore it out on just one wheel. Worked great though. The wheel's beautiful now but brand new wheels are only $6 or $8 bucks.
I ain't asking because of the money - it's peanuts - but I'm curious.
I need another. I wanna keep after 'em from now on. Is there a difference with another better brand or did I use it too hard? Can I buy a bunch of replacement star-point wheels for a decent price anywhere? Are the diamond ones longer lasting? Which one should I get?
Just appreciate any experienced metalworkers input to satisfy my curiousity.
