Long and winding road with many a "turn" she ain't Swiss she's my gang tool .
Ok .562 hex steel, using all Iscar inserts. RPM 3000, can go 6000 but with hex it ain't worth it.1/4" 28 3A thd. Shoulder .315 +.000 -.001 3A thread has to be run so the no-go gage is snug for zinc plating.
Turn IC 907 (flip corner at 2000 pcs) WMNG 3-2-TF IC907. .032 radius (yes I'm facing to X - .050) Same on me . Face front of shoulder & back of head to .530 .015 back. And clean up the .032 radius. WMNG 3-0-SF IC530N ( flip corner at 6000 parts). Thread iscar topping 16ER 28 UN IC508 (Flip corner at 7000 parts).
Cutoff DGR 2200JS-15D IC3028 (take out at 1000 & hone radius) Comes with 0 radius which is about .003 Run for another 1000 & change.
Kids, don't try this at home with toilet water (the Icsar rep will love you).
