I build a lot of toys for my grandson. Very often I use a dowel which goes through a hole. In most cases ,for example, if I drill a 1/4" hole, a 1/4" dowel is too tight to fit in the hole I drilled, so I drill the 1/4" hole a 64th larger and everything works fine. However I am now drilling a 1/2" hole for a 1/2" dowel and the dowel will not fit, I don't have a drill bit which is 1/64th larger than a 1/2". Other than buying the 33/64 drill bit, is there any way to very slightly enlarge the 1/2" hole to fit what is obviously a 1/2" dowel which is slightly oversize?
Thanks
