Splitting A Sound Hole Clamp In Half
I recently had a guitar come in with a crack in the top. The top was an arch top so the top was thick and the crack uneven from side to side so I wanted to be able to supply more pressure then just using magnets to be able to even up the crack sides. But access was limited to a small sound hole and so no way to get jacks or a clamp to fit. I also wanted to use full length longer cleats instead of fiddling with the tedious fishing reels and thin wire. I really wanted to get a clamp to the crack. So after thinking about it, I realized that if I cut a clamp in half, I could get half the clamp to fit. This opened up a whole new world of possibilities. I searched on line for a clamp cut in half but no such thing exists. So I fabbed my own. The following vid shows what I stumbled on. It works for certain F holes etc., as well. I hope it’s of use to the community. https://youtu.be/nynDBOVJppw?si=jBcvietV0-QQLkWN

The only change I would make would be to remove a section of the threads from the clamp assembly bolt to make it easier to insert and align the two sections. Basically using the bolt as a bull pin until the threads can be engaged.

Cool. That screw is, in fact, a bull pin. The plate is not threaded. The threads help hold the screw/pin in position (won’t wiggle/fall out) Your take is spot on and the whole idea of sharing with the community is the point. Put a hopefully helpful idea and present it to the community so the idea can become the best it can. The tool was made in about ten minutes. It can definitely be refined. My trip is trying to create tools that are easily accessible and can be made using simple resources and basic hand skills. Functional, cheap, easy to make.

Nice. I guess my mistake was watching the video on a tiny screen and assuming the pin was screwed in. But just pinning it makes for faster assembly during the glue-up process.

Yes, once again you nailed it. And I stumbled onto leaving it as a screw pin because of exactly that. I had previously used a nut to back the screw up during dry runs but during actual glue up pressure, realized I didn’t need the nut. So what you see is the learning curve. I wiggle/screw/push the screw in on vid. I still used the screw because the threads grip the screw pin in place from clamping pressure. So I decided to leave threads instead of smooth pin. The fun was in discovering how to apply/improve the tool. And it’s even more fun watching the mechanically minded, inquisitives like youself doing the same. Yay!

Second iteration. I have a video coming soon on how I put the thing together and showing the different uses I’ve come up with so far. It makes cleating in hard to reach places, gluing braces, bridge plates, bridges, etc., much easier.

whoa. This is very cool. Nice work!
