Recently I bought a Caldwell Rock front rest. I have been ok with it other than the fact it "wobbles" side to side when you adjust up and down. I should have bought the competition version. But rather than shell out even more money, I was thinking of modifying my rest to make the vertical adjust more precise. The weight will not be an issue, it can weight thirty pounds for all I care. The issue looks to be the adjusting wheel itself. I don't believe the hole was drilled and tapped straight. I was wondering if you guys have any slick ideas I could use to modify this thing.
