- Solid brass rest heads.
- Cross rest head and low spider rest head.
- Rest heads are made with a sharp thread that cuts into the shaft and pulls the rest head tightly into place. If necessary carefully use a utility or modelling knife to trim the shaft end down to size. Thread the rest head clockwise into place. There should be no need to force the rest head on, if it is too tight remove and trim a little more and then re-fit.
