Stigma Amen 10w problems- any help guys before I throw it

[Carlsworth]

Think I get what you mean about the stroke vice- Double checked everything, and its all tight and secure

Just don't understand why its rattling itself to bits-
have to keep tighteneing the top adjustment screw when using the machine anything other than solid

take a screw off and put a little bit of paper towel on the screw.
i did this to mine and it works perfect
