Fred. Thanks. No problem. I cut a lot of hard stainless. I've developed a few tricks that make job palatable. My suggestion is play with your face and heel angles till you don't tips every 5 seconds. The 120' graver is a must. I worked on this gun from Saturday evening through 5pm Sunday. I only had to sharpen my graver 3 times in the 12 hrs I put in the gun.
