I resolve NEVER AGAIN the turn the lathe on backwards on the finishing cut on the inside of the boltface with the meticulously ground hook tool.........
NEVER AGAIN!
Ha, ha, ha!...Tell me about it, some 20 -25 years ago I did the same while cutting a chamber for a hunting rifle, I reversed the lathe and ruined the edge of the reamer...I left the barrel as it was and ordered an identical reamer which I got within a week...Went back to the shop and finished the chamber but got distracted and lost my concentration and MADE THE SAME MISTAKE AGAIN !!! This is a very common mistake if you do a lot of drilling with your lathe but is not a good excuse.
Man, was I upset with myself !!!
My dad used to tease me: "Men is the only animal who makes the same mistake twice...And you my son seem to be the only man who does it among men"
