Scale Model Precision Grinding Vises

[old_toolmaker]

steamingbill,

When tool building and I intend to precision grind, I will normally mill oversize and leave .005" grinding stock per side for finishing to size. It is possible to plunge grind from the solid and I have done that also on ocassion, but for larger flat surfaces it is usually not practical to do so. I will usually use a 46 grit H hardness 7" diameter x 1/2" x 1-1/4" I.D. aluminum oxide wheel for most things.
Thank you for asking.
