I'm assuming these are DPA's. Make sure you're not overtightening the jam nuts on the pivots, as this can cause some frown or smile to the knife. Also, verify you are grinding a "true cylinder" so you're not putting unnecessary twist into the bedbar when adjusting it to the reel. Verify the top and face specs for the bedknife, but also, if you have any reel or bedknife wear, don't be afraid to knock an extra degree or two off the top angle, for instance if spec is 5 degrees, maybe 6 will provide some relief. Some of these bedknives are thicker than the shoe they mount to, and tend to rock back on the grinder if it has magnets. You may need a shim (I use wood) to hold it up so that your angles are truly referenced of of the bedknife itself. Also, if these are Edgemax bedknives, I like to spend some time deburing them after grinding with a wood block. Lately though, I've been finishing with the top angle, then using a bedknife buddy on the face to debur it. A flat file will work too, just use caution as that material rolls off in splinters and will go right in without asking. Last thing comes to mind is the grinding procedure itself. Verify the stone is coming all the way off the reel and/or bedknife before it stops to change direction, both machines.
