Recently I have been having problems with my Port. Floor corker. Its been taking a small chunk out of a corner of the cork where it hits the bottle. Dont know why I didn't investigate this more the firt few times I was corking but today I did as I have a new corker on my shopping list and hate spending money on something I already have. I discovered the problem was 2 fold. Both the plunger somehow got bent out of center and the bottle holder (the part underneath that holds the bottle top where it should be) somehow also got maladjusted. I placed with both of these and now my corker works like brand new again with little or no dimple in the cork, the corks go in very easy and no little chunks missing from one edge. Now I can spend more money on wine!!!
