Q - Would the 320 grit be adequate to resurface a Venev 3/2 F1200 or do I need to match the numbers.
A - To flatten your stones, even a lower grit than 320 would work fine. If you want them to perform optimally and be ready right after flattening, then it is worth using a finer grit powder (closer to the grit of the stone) after you have flattened them. If you only have the 320 grit, then you can use that on all the stones, just note that the finer stones will initially perform with a slightly coarser feel and scratch pattern but they will settle in within a few minutes of use again.
With the Venev stones, it is the diamonds inside of the bond that does the cutting when sharpening. The bond merely holds the diamonds in place. This means you can use any coarse grit silicon carbide powder to flatten them without being too concerned about their long term performance. After using a very coarse grit, the stone will have little deeper "grooves" in them which expose more of the facets and surface of some diamonds, so initially they perform slightly more aggressive. After a few minutes use though, the bond breaks down and releases the rogue exposed diamonds and the stones go back to their optimal performance.
