matching curved pieces
so my wife wants a simple yin/yang out of walnut and maple. i drew an 8" circle. then i made a curve from top center to the middle i copied the curve and flipped it over to make an s. then i cut the circle in half, copied the s, joined both half circles to the s's and saved each half to a different layer. i am using a 1/4" endmill to do the cutting. first try i cut on the line. they didn't line up. after inspection i could see that they would line up at about a 1/4" apart. easy fix i thought ,cut on the outside of the line. try #2 and they still don't match. now i am .14" apart. now this has me buffaloed. measure the bit and it"s exactly .25. shouldn"t they match up exactly?thank you in advance

Post the file and we can probably figure out what happened.

Re: matching curved pieces
thanks FixitMike. i went to post the file and was looking things over with fresh eyes this morning when i noticed that somewhere along the line i switched the tool to a .125 endmill and used a .25 endmill. there's my difference. i am going to try again tonight after work. i will post my results on here when i'm done. thanks again FixitMike

Re: matching curved pieces
You might want to consider offsetting one or both of the parts inwards by .01" or so. It may work fine to cut them to exact size, but sometimes they fit together better with that tiny offset
