Hello Dale, The Brinsmead does have a tuning system in principal like Mason Screw Stringer. However that is where the similarity ends. In a Brinsmead the string go in to the end of the screw and comes out the side about half way up. It then laps over the top end (in a groove) and comes down the other side. A smooth cap then covers the screw head and the string. The cap comes off and the square screw head can be tuned. The size of the screw head is 10 mm. The Brinsmead like the Mason carries its own special tuning lever. Don't lose that lever I had to have one made Good luck and enjoy, Jack Wyatt stringer -------------- next part -------------- An HTML attachment was scrubbed...
