Default Flat belt mechanics

Useful to remember if no machine shop available for making a bulbous pulley,
if faced with replacing a motor and its the wrong speed range so forced
change of pulley , or smaller spindle diameter. Except the ridge is
semi-circular profile here and bodge job would be chamfered edges but
starting from a brass rod it would be a lot easier to fashion leaving
central ridge, bodging 2 cone segments and 2 end faces , than fully bulbous
without a lathe
