I sure wish they had those polycarbide disks back when I restored my '29 Ford pickup in the 60's. I went thru sandpaper disks and wire wheels by the dozen. More than once the disk went whizzing over the hedge to the neighbors's yard.

I picked up a polycarbide disk at Lowe's, and MAN does that thing work nice

. I haven't used it much yet, but it's gonna get a workout on the '51.
