3X3X3 cube of steel.... we want a .050" chamfer on all corners;
Two ways to look,and process engineer this(and your OP). 1st,we pop it into the vise on a Bridgeport and go to town. The 2nd,or other way is to file it. The first method is high on tooling/equipment and within reason,low on skill(could even be CNC)..... plug N play if you will.
2nd method was very high on skill,low "tonnage" on equipment. Yes,you need a great file.
You've got to understand the difference in how that translates to your issue of length. Trying to diagnose "skill" or technique issues on a net based forum is gonna be tough..... well,compared to someone observing? Reckon you could take a vid. But hope you catch my drift.
To say,"you're not doing it right" or you haveta hold your mouth just so is a little(lot),short sighted. About as bad as saying "get an XY piece of equipment). It's up to each individual to understand where they want to draw the line.
I'd say.... assuming you have decent kit,there's something in your skillset that's causing the issue. If you consistently do something wrong,pull to hard... dwell too long,etc. the consistency "should" produce say,a bunch of crooked bullets but hey,they're all the same "bent".
If it's intermittent,or occasional then it's "probably" you introducing the error. How? Beats me.... just sayin,try to distinguish between skillset vs tooling/equipment.
Good luck with your project.
