John Ford and Tuner's Supply sold 25 years ago (haven't bought one since
then) was 3/32", and even that is sometimes a bit large for the bushing
cloth they sell (typical).  5/64" is probably too small.  If 3/32" is too
big, try a numbered drill somewhere in the #42 to #47 range.  Buy bushing
cloth in wide sheets and rip your own slightly wider widths.
    You'd think all this stuff would be standardized by now.  One drill.
One width of cloth.
