    I did this DIY a few years ago to an old Alvarez acoustic with the same type of crack. I used two strong magnets, one directly on top of the crack, and one stuck to the cleat with two sided tape. The magnets naturally find each other and stick together to act as a clamp while the glue dries. It worked pretty well.

    A hygrometer is a must! I have a (poorly made) Seagull Pepino guitar. I believe the wood was not seasoned well enough. But in the winter my apt gets brutally dry and even with a damp sponge in a plastic bag with holes in it (inside the sound hole) the guitar still cracked. My luthier fixed it (along with a saddle fix to fix the poorly set intonation). The humidity thing is real, though. Especially in winter. I put damp sponges in a plastic bag with holes in it in all my guitar cases in the winter--and I never leave them out on the stand. Dan is a treasure, for sure.

    Very cool. I was wondering what a cleat was when I read the video description, then when I saw what it was, I chuckled because I fixed a crack in an old arch top I once had by using a popsicle stick as a cleat.

    Helpful tips. I just happened upon a classic Levin guitar, made in Sweden. Nylon strings, beautiful tone, so easy to play. It did come with the bridge torn off, since some nut job had put high tension steel strings on it. I got the bridge succesfully glued back on, and it sounds wonderful. The body does have a few cracks, so I will have to address that. This video was most helpful. I did some research, and found the serial number chart for Levin guitars. It turns out mine is a 1954 model! A good 20 years older than I initially thought. Definitely worth restoring.

    I have learned a lot from watching these videos and from reading Dan's books , but something I've notice about every guitar dyi UA-camr gets wrong is that not everywhere in the USA has the same weather pattern. My winters are wet and humid while our summers are hot and very dry. Right now outside humidity is 23% while inside is 37%. Your best tool have is a hydrometer to closely monitor the moisture in the air, so you'll know if you need to humidify your guitar or run a dehumidifier.

    I inherited a tiple and a balalaika from the guitar teacher I had in high school. They both had cracks in the tops and were unsellable, so his sister told me to keep them. I took them to a repair shop who said it would be hundreds if not upwards of a thousand dollars to fix them. They are not high-end instruments, so I think I'm going to use this video as a guide and try to fix them myself. Thanks for making the video!

    I have many guitars but only one is really special. '68 Goya folk guitar. Dad's first guitar, my first guitar and my son's first guitar. It got impact cracks from living under my dorm bed in the late '80s. Bashing punk tunes out of it was needed at my sucky military school, but that didn't help either. Before my son was born dad gave me the guitar but first he had it repaired professionally. Cost nearly it's value, or more, but a job well done. My son is very careful, and it's his favorite guitar to take to school where he has lessons and jam sessions with kids...but now it's cracked again. Luckily he likes his $70 Strat that I fixed up and his Boss Mini amp and he's big enough for a 25.5 scale guitar now. No more classic acoustic going to school. I am determined to fix it myself. Meanwhile, I will fix some guitars at a school I taught at, for free, to be sure I know what I'm doing. I doubt I'll ever be a great player, but I do like modding and fixing and setting up guitars. Living in NZ it's lucky I can do the StewMac membership as the shipping cost is otherwise a real burdon along with the exchange rate. And I am done with Ali Express...EVERYTHING they sell is terrible.

      ​@@micsayre Well buddy, i'm in the Philippines.. and the level humidity here is grossly abnormal. if i could send you photos and videos of how the humidity had compromised or destroyed items made with Wood, Leather, cotton or even paper.. you would think otherwise.. (tons of things i kept inside my luggage bags got FILLED WITH MOLD). Bamboo Flutes and Wooden Saxophones were starting to get filled with mold. A leather belt i had, became mold city. i had 3 guitars that were fine until i brought them here.. then the Bridges started getting loose and disconnecting on them.. i complained to the building's office managers & of course that got me nowhere (they simply think i'm trying to get them to pay for things that were damaged and go into denial mode. They told me i was the only one who had complained about such a thing. Then one day one of the building handymen came by to fix something electrical, and i showed him my humidity and MOLD issues, and he said he gets the SAME thing). I got a Taylor Mini GS Bass, and knew that i had to do something extreme to save it from what had happened to the others.. & so far, what i said i did in the comment above has helped. The level of mold has almost disappeared.. and my Guitars & that Taylor Mini GS has been fine.. so far. i'll add, my electricity bill from using air coolers is ridiculous. So, when you're in abnormal, judging with a normal mindset is not correct. Someone once told me "One Lid (pot top) doesn't fit every pot.."

    My uncle Dan - good name, eh? - was born in Longreach, Queensland. Edge of the desert. But he moved down to the North Coast of NSW, took up surfing, took up guitar.
    One Christmas he went back to Longreach to visit his parents, and took his beloved White Falcon to play a few gigs at the pub.
    When he got their, after a day or two, the poor White Falcon had arched up like a longbow. Strings nearly half an inch above the frets.
    "And that's when I realised that guitar," he said, "is a coast guitar."

    Where do I buy the magnetic film and cleat holder?

      You can find the magnetic film on Amazon. The cleat holder was custom made. There's a chance we have something like it available someday, but hard to say when.
