Thanks, I got in there and removed the set screw (mine had only one in there) and lowered the wheel. I appreciate your help! Then I go to recalibrate the holder and sure enough, I lost my calibration block, hahahhaha. I guess I'll do it by trial and error.
And I have to give a big thumbs up to Blackstone's customer support. I posted this here because I thought I'd get a quicker response (and if someone else needed the information they could see the solution), but they gave me the same information you did, and very quickly!!
Before I bought my sharpener and since, I have read many pages of this thread. i am reading more and see that it has been posted a couple of times.
