Have a 1991 Catalina 28 and the Table will not stay in position when tightened down. I am afraid to over-tighten the t-handled screw. Has anyone come up with a way to improve or replace the locking mechanism on these boats. Also this weekend the wood block holding the folding struts for the leaves cam off the bottom of the table completely. Any suggestions would be appreciated! Thanks, Michael_woody@hotmail.com
