Yes. Two washers were included in a small zip lock bag along with a 1/2″ screw I assume is for the top hole on the vice jaw clamp when sharpening a low angle item like a straight razor where the usual screw would stick out too much and get in the way of the stone. Didn’t know what the the washers were for at the time.
After going back and reading “Assembling Your Pro-Pack II or Pro-Pack II Upgrade Kit” under Resources / Instructions it says in Step 5: “To mount your sharpener to the Mounting Plate, slide the the included washers onto the #10-32 Flat Socket Head Cap screws with the metal side facing the heads of the screws and slide those through the underside of the Mounting Plate. Thread them into the holes on the bottom of the blue sharpener Base and tighten them down with the smaller of the hex keys on the Vise Key. Affix the four adhesive backed rubber bumpers to the underside of the Mounting Plate at each corner”.
So I didn’t have to go to trouble to get washers myself. Still, you would think they would have being put on by when assembled at WE. A thought that occurs to me now is that my “assembled” unit was just a quick put together to fit in carrying case and I was supposed to know enough to take apart and reassemble myself.
Regarding Cleaver, the original angle was around 30 degrees but the blade is quite thick behind edge so when I am putting the 20 degree (10 on each side) relief on it I am creating an edge that is almost 5/16″ wide which is a lot of metal to grind down. I am sure the 100 stone will cut the much smaller cutting edge just fine.
