    Neodymium magnets are a great boon for many things- as others have pointed out, I have also used them at times for clamping cleats in place more easily than the tuner trick, as long as I have landmarks inside for positioning by feel- just want to be careful positioning cleat and inner magnet and then apply the outer one straight down rather than approaching from the side to avoid pulling the inner assembly sideways. One thing, though- when using magnets to align an initial crack glue-up, I now make a point of making sure I’ve got a bit of wax paper between the magnet and the guitar top to prevent the magnet from sticking to glue squeeze-out on the top of the instrument.

    I love your technique! Several years ago I talked a music store manager into selling me a nice Alvarez guitar that had developed a crack in the top while hanging in a window display facing the street in front of his business. I paid $50.00 for the $500.00 guitar. I took it home and went to work on the crack. Having no clamps to get inside the sound hole, I worked some glue into the crack, then used rare earth magnets to clamp cleats on the inside. I have always been nervous that the magnets did not provide enough clamping force to properly adhere the cleats, but that was 7 or 8 years ago and I still play that $50.00 guitar every day. At least now if those cleats come loose, I know to drill some holes and make a tool like yours to make it right so my grandchildren can inherit that Alvarez some day!

    I used to use the same method with a modified tuner and guitar string for cleating cracks back in the late 70's & early 80's, but now I find that using a pair of magnets for each cleat, I can do the job without making the tiny hole necessary for passing the string through the top. I use a little double stick tape to temporarily affix the cleat to the inside magnet. The ones I use are so strong that having the top and cleat between them still allows for plenty of pressure to "clamp" cleat to top.

    yes....I use magnets too. I usually put tape on the bottom of the top magnets so as not to possibly scratch the guitar. I also use top and inside magnets to glue/hold the wood tabs in place. I take a small piece of putty to hold the tab to the inside magnet, (blue tape the magnets to the top so they stay in position.) Then when you install the inner tabs/magnets they self align because of the pull from magnets taped on top. COOL

    I like your clamp idea. I have an issue with the back plate of an Autoharp, where the back got a lengthy crack, and was pushed inward, when it was dropped by its past owner. It received other damage issues at the same time, which I was able to correct easily, back to normal again. It's a tight squeeze working inside an Autoharp with such a small opening on its face, but I think your idea will work in getting a good solid repair on this harp, and flattening the damaged crack area back to close to normal again. Going to give it a try. Thanks for idea.

    As a musical instrument repair student 35+ years ago I learned from my instructor that Acetone is what lighter fluid is made from. Be very careful with it around plastics - celluloid for bindings and such was glued together at its ends by wetting with acetone. I learned before going to school that it would melt the celluloid.
    To glue the cracks I set the tip of an opened titebond bottle onto the end of the crack and slowly squeeze glue into it. By watching inside, using a mirror and light, I can see that the glue has penetrated through and slowly move the glue bottle's tip the full length of the crack

    Just made and used this tool... glue is drying now, hopefully it turns out as good as expected!!! really great idea, the guitar I'm fixing is a martin backpacker and the sound hole is only about 2.5" across, the crack is pretty far back so there's literally no other way i can think of to get a brace in there... instead of drilling a hole i used a small sewing needle to poke a hole, since the smallest drill bit i had was 1/16th.. also before doing this repair i humidified the guitar to get the crack to shrink as much as possible.. it's almost invisible now even before doing the brace and glue

      I'm curious on gluing the cleats to the inside of the guitar. .seeing as you don't need a lot of clamping pressure when gluing the wood cleat across the cracks why not just use some dowels or sticks cut slightly longer than inside depth of body to apply just enough pressure to hold cleat in place until the wood glue dries? I hope you understand what I'm trying to say... it would eliminate the need to drill tiny hole and tying a knot in cleat and pulling it tight with the headstock jig you made.

    • @advankuijk
      @advankuijk  5 лет назад +1

      Hi Dan,just try to make sticks that are exactly the correct height to give pressure without lifting the top. It's almost impossible. That's why! Hope you get the point.

    • @maplebones
      @maplebones Год назад

      @@advankuijk They don't need to be an exact height. They need to be a little longer and then gently wedged in. You can counter any raising of the top with a counter weight.

    During my thirty years at the bench i often used a tool like this, but would NEVER use it on the top of a guitar with a soundhole. For back cracks in F-hole guitars, yes.......but NEVER where i could reach in and touch the crack. Simply use your good magnets to pull the cleats against the crack.....fool proof and no holes in the top, no matter how small.

    @stevensantos369 6 лет назад

    Not to diminish your expertise as Iam in training and you obviously surpass me. However, my opinion is that perhaps you should have only set the middle cleat perpendicular and the others parallel. Or, perhaps all of them slightly off parallel. I wouldn't want to diminish any natural resonance from direction of wood fibers. Yet I understand your preventive measures.

    @Tsunamiguitars 6 лет назад +1

    I'm like R Scott down below, using the magnets to hold the cleats in place while the glue sets up. My customers would never come back if I drilled multiple 1MM holes in the top of their very expensive guitar. Refinishing that to match is actually much harder than you make it look. Tinting to an aged finish is hard.
    Actually, I use a rubber covered clamp across the top to bring the crack together once the glue is in place. In ten years of doing this kind of work, never had a crack I could not get together. Just had a mandolin recently with no less than 7 cracks on front and back - got them all home again. Magnets are a cool idea, though. But forget the holes. Not going there.

    • @advankuijk
      @advankuijk  6 лет назад +1

      I only use this method when all other methods like yours are not possible. I don't drill any holes if there is another solution. Just showing that this is possible too when all other things fail. The holes aren't that difiicult to make them dissapear. Sometimes this is the only thing that works.

      it's my own music. I only use my own soundtracks on all vids. All music was recorded in the 90's with minimal computer aid.. Thanks if you like it!

    Saw this procedure on Dave's World of Fun Stuff years ago.

      It works really good on side cracks.
