80 grit in the flapper wheel at 800 rpm (this might vary with head diameter)... and you can't use an off the shelf standard flapper you need the special head (which you have found out but others may not realize). As far as width I'd go with the narrower one if you can only get one (I think 1 inch is what I have seen). The wider one may cause problems and irregularity around curves like the fender flares and some other tight details... I am not an expert but I think this is the right info.

I'm now armed with a 1000 RPM pneumatic drill and a beater RF fender to practice on. All I need is a Wolfhead wheel. For those of you who have experience with these (or even an old Vonnegut wheel), could you help me fill in a blank or two? 1) What grit abrasive matches the factory grain? I've read where others have used 60 and 80 grit, but I've seen no consensus between these two. 2) What slashing pattern for the (aluminum oxide) abrasive is best: 1/4 or 1/8 inch? 3) What width wheel to get: 1, 1.5, or 2 inch? I'd assume 2 inches is a better choice since it covers more surface area... unless there a compelling reason to choose a narrower wheel? I know from talking to G&P machinery that some combinations of the above may not be made, but I have too many variables to figure out the rest without some trial and error. Any insight would be much- appreciated! Many thanks!
