I'm so glad I found your video. I have the same satin mahogany Martin D-15 with a crack in the treble side, and it's reassuring to learn that it can be repaired successfully. My heart stopped when I discovered that crack.
@@Barringtonjohnbruce Just checked out your Fixing a Top Crack in an acoustic Guitar. Really clean cleating work. Totally going to use this on a collector Yamaha FG 331 if found. Subscribed!
Wow. I have the same model w the same crack. I’ve already jumped in before seeing this video and closed it up with magnets and hide glue. Yikes 😬.. I now think I chose the wrong glue. Gonna add a rib/brace to try to lock the crack - thanks for this vid!
Very nice work . We have a cello with a similar crack and will be doing something like this procedure. Thanks for the video. What do you charge for a repair like this ?
This might seem a silly/weird query, but are these size cleats ‘ big ‘ enough ? I have similar damage to a Framus 5/297 Jumbo I bought and was thinking diamond shaped cleats around 3/4” wide and possibly 1 1/4” length to accommodate the strength to put back into the body would be better ?
What you are thinking would likely be better at grabbing at more of the side wood, as they would be 2x the length than what I used. But where I was able to put glue along the crack as well as use the cleats , I have no worries about this Stewmac cleat system. Titebond has great strength and depending on how many cleats you put ,you can make it as strong as you want . Too much wood/size of a cleat, will deaden the sound on a top/back crack. This is less critical on the sides. So what you are suggesting could possibly be as good if not better -yes. Thanks for watching and good luck!!
The string is right in the middle of the crack, and once the glue is dry pull the string out from the inside, through the soundhole, then find a suitable material to fill the hole (glue mixed with sawdust will work) The hole is just the size of a small e string.Thanks for watching Kevin
Sorry I didn't see this sooner. What I may do if I'm filling the hole in spruce ,is to sand (with 220 grit) some scrap spruce, then mix it with titebond or any carpenters glue, and fill the hole with this paste you just made. Then wipe the surface with a damp cloth and let dry. Here are improved spool clamps. www.stewmac.com/luthier-tools-and-supplies/types-of-tools/clamps/stewmac-spool-clamps-set-of-6/
You could cut spruce like this into diamond shapes for patches as well.- www.stewmac.com/tonewoods/shop-tonewood-by-instrument/acoustic-guitar-wood/braces-and-blocks-and-blanks-for-acoustic-guitar/spruce-patching-wood---set-of-3/
