sprior said:The screw hole I was referring to is in the top of the cabinet. If you look at the round piece of dowel on the right you can see it is screwed into the top. What I'm talking about is drilling a 20mm hole through the top centered on the existing screw hole once that dowel is removed. Then I can slip the plastic dog into that hole and it will have the same dimension and location on the table as the piece of dowel it will replace, but it will simply pull out of the hole when desired.
Sorry, I get what you are saying now. ;D
