The 20P reamer looks so fragile. Doing my first 20P chamber and i am going very slowly, the flutes on the start end of the 20p reamer are tiny and fill up quickly so i am going very slowly.
I am about 1/3 depth so far and seems like it is taking forever. my setup is in an older southbend heavy 10 with a vfd and using the backgear running about 30 rpms seems that about .015 depth and the flutes are full. chamber looks great so far so i guess i will just keep going very slow and will get to the proper depth in a bit.
I indicated the bore in on both ends Chuck and Spider to less than .0005 before starting

Does this sound about right to the guys that have done this?

Thanks
