Hey woodworking fedi, how do I repair these in a way that does not cause trouble later on?

Currently they do not go all the way through but give it another 10 or 50 years and they likely will as the wood continues to shrink. So what do I need to do to make this thing usable now and repairable later?

@skye I do not have an actual answer, sorry. But I frequently watch this YouTube channel from a guy repairing guitars. Maybe there's something similar there? https://youtube.com/@twoodfrd

I make and repair stringed instruments in Hamilton Ontario, situated in the magical frost kingdom of Canada. (I don't accept repair requests from the USA- shipping across the border is super expensive and fraught with risk. You should find someone in your state to look after your guitar.) woodfordinstruments.com Hats and shirts: https://www.bonfire.com/store/woodford-instruments/
