Thanks in advance, Bill

Boring 0.002" smaller is too small. For motor pulleys go for a size-for-size fit or slightly larger; i.e., bore 0.500" -0.000" +0.001".
Boring 0.002" smaller would make it impossible to get the pulley on without heating it and shrinking it on....then you would never get it off!!!An open mind is a virtue...so long as all the common sense has not leaked out.
