Finally got around to crowning the tires on the 32" BS I am refurbishing. Using a metal lathe I turned a 4.25" (L) round bar down to 1.25"OD X 3.25"(ID and width of the BS wheel) and the remaining 1" down to 1.095" to fit the collet on my homemade wood lathe. After locking the 1" end into the lathe I mounted the upper wheel onto the exposed 3.25" section and tightened down the wheel set screws. Very Carefully I turned the lathe on (slowest setting), to my amazement it ran very true and smooth. I then started removing tire material with a freshly sharpened 5/8" bowl gauge. I used Bob Vaughan's TLAR technique (that looks about right) and tried to get the crown somewhere in the 5-7 degree range. I went ahead and wire brushed and painted the wheels while still on the lathe. Here's a link with a few pics.
