I need to close a seem on top of a martin d-35. It's BARELY open but well, its open. Super thin spruce splices? Sooo thin....
I will. It didn't separate due to dry ness, but rather got to warm. But if itll drink that would help it close nonetheless. Thank you for the reply I'll offer it a drink. Colin
I would still check the RH in your area. It does look like a "dry"crack. good luck!
Hi, I'm new here, been looking for awhile and thought I'd take the plunge and join in.
I have found that closing the gap without gluing it first could result in it opening again with seasonal fluctuations. With very small cracks I have found the The moisture in the glue, rubbed into the crack, plus a bowl of water placed carefully insde the guitar, does the job. I cover the soundhole and put the guitar aside with a not on top saying, water inside.
I have also used a glue by Veritas, Chair Doctor, that claims to expand the joint as it dries, it dries transparent and cleans up with water.
