Here's what's happening.. Get my bevel set on the 1k passes the tnt ..I have had success setting bevels.. I'm using choseras so I then move onto the 3k then 5 k then 10,15,20 k suehiro.. My problem is as I get to higher grits the bevel is gone..?? I have read here that it's possibly a pressure problem.. ?? I usually use a good amount of pressure on the 1k to set bevel.. Then diminishing pressure . Hit the 3 k same thing.. Great pressure during the starting strokes and diminishing pressure as I finish.. Same all the way up.. I have just been testing my bevels at 20 k just to see if I still have it after the 20 k .. Guess what the tnt isn't grabbing??? Suggestions.. I have had success in the past with a great amount of razors ..I'm no pro .. But what's going on??
