I'm filling screw holes in the mast on my Catalina 22 sailboat. I have removed all of the hardware from the mast and boom and intend on using an aluminum threaded rod, epoxy, a hack saw, 1/4-28 tap and die and a 3/8 drill bit in order to fill the holes. Once the repair is complete I will drill new holes in order to attach new or refurbished hardware to the mast and boom.
