Hello I'd like to ask if it's professional to repair cracks without opening an instrument? If it's a crack located close to a border, would it be ok to not put cleats? I used a very fresh transparent strong fish glue, but I didn't install cleats.

Evan Smith

I loosen the top from endblock to corner to relieve stress, and re glue in a week or so.

Brad Dorsey

I often glue top cracks from the outside; i.e., without removing the top. When I do this, I always open the top/rib seam to allow the crack to close. Because your crack came out very nicely, I think you have very close wood-to-wood contact along the crack which gives a very strong glue joint. I don't think that cleats are necessary.

I once glued (HHG) a crack in a Guitar without putting in any cleats. It was a cheap repair and the customer was poorer than me. It popped open after a day or so. I reglued again. It popped open again. I reglued (it was the final attempt!). I saw the guy a couple of years later and he said that it was still holding fine!
