The first set was still in great shape, none missing, reaming sections still sharp and cutting well. Problem is, I had always had problems fitting size 20 1/2 (.051) bushings. The 051 reamer made them too loose, but the 050 wouldn't get them loose enough. So I put a mic on the reamers, and found that all were correct size, except the 051 was actually 052. Since I had been using this set for many years, I figured the warranty expired long ago, so for $20 or so why not just buy a new set? Well, here's why not: The sizes of the new set are all over the place. broaches are oval by 1 to 2 thousandths, reaming sections smaller than burnishing sections by 1 to 2 thousandths, and again the 051 is closer to 052. I anticipate that when I call Schaff, they will be willing to exchange, but the new set is likely not going to be any more accurate than what I have.&! nbsp; Is there a source for accurate broaches? Must I learn how to make my own? Any other thoughts/ideas? thanks much Mike Michael Spalding spalding48@earthlink.net ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
