I am replacing a cracked rib on my 1931 OTCA and have a pretty basic question that I'm sure has been covered before. When hammering in the new tacks, do use the same tack location/holes from the previous rib or do you fill the existing holes and use a new location?
Additionally, I am replacing the stbd outwale. I've steamed and scarfed the new outwale to match the one that is being replace but need to drill pilot holes for the screws. I need to match these pilot holes to the existing hole locations in the ribs and inwale. Obviously because the screw does not extend through the inwale, I can't simply drill the pilot hole through the inwale to the proper location. Instead, I created a tool similar to a strap duplicator used for aircraft sheet metal construction to find the proper rivet hole location when one hole already exists. Has anybody else done this and/or does anybody have any other ideas for determining the exact pilot hole location when replacing the outwale?
