I am having a difficult time making an even stroke on the first leg of a pass on the 4000 side of my norton combo stone. The toe of the razor always seems to meet some resistance and lift off of the hone. I have lapped the side in this manner 4 or 5 times.

I soaked the stone and the flattening stone for about 15 minutes. Then I put the stones on top of each other and rubbed until the pencil grid was gone. I held one stone in the right and one in the left. and am having the same problem. Would pressure be used in this instance? I am just beginning honing and do not know what the problem is and how I should fix it.
