Here is a solution (among many others) to attach a tailpiece to your violin. You don't need many tools except a pair of pliers, but you will have to get a kevlar tailpiece which will be available only in specialized stores (like my store). Other materials might stretch too much or not be flexible for this type of use.

PS: Please excuse me for the somewhat "off" framing on the second part. I hope it will still give some information.
