Maybe this was another metric vs. USA issue, or maybe it's just a bad detail in the plans, but the notch I cut in the table support to make room for the lower powered wheel isn't long enough to pull the wheel forward and remove it from the shaft. To remove the lower wheel, you have to take the table off. So after removing the table to get the wheel off, I chopped the notch a little to make getting the wheel off easier in the future.
And here's is the top wheel reassembled after putting that shim in.
I don't have enough hands to hold a long straight edge and take a picture at the same time, but this picture is supposed to show that the top and bottom wheel are coplaner now. Yay.
With the top wheel pulled forward, the blade guard made out of the oil can doesn't fit around the wheel any more. So I have to make a bigger one. Fortunately, I have another one of those big olive oil cans in my junk pile. This time, I plan to use the English side of the can.
