The 4th part in the series restoring a German Maggini copy violin. In this video I show the process i follow when fitting a sound post patch, trimming it back, and the final product.
Thanks , needed to see that , great work , me , my problem is I am not sure my violin needs a patch but I am thinking about it now . Its hard to tell the damage on the spruce side is minimal but visual sinks in about half mm ? sound post markings , not sure ... my back place has a mark or two but not enough damage . I LOVE your clamps !
Wow! What a masterful job! I’ve seen people (on RU-vid) inlay cracks before, but only straight ones. Never saw a jagged crack like that filled before. Also, the patch fit so perfectly. I really like how you aged the patch, as well. Amazing work mate! I’m curious, why would the back crack from the sound post, when maple is so much harder than spruce? Anyway, a happy, healthy, and prosperous New Year to you, and your family.
Thanks Rick! And a very happy new year to you as well mate. The reason I believe the back cracks but top didn't, so the back is a hard wood yes but it's also more brittle, the spruce while soft has a cushioning effect where the grain compacts before cracking, it also has counter pressure from the bridge foot supporting it and this also absorbs the energy from the impact. If the impact is from the top though it is carried through the bridge and soundpost to the back plate, the energy is then expended in full force on that one small area and if the soundpost is positioned right along a grain line then is likely to crack. I hope that makes sense. It's only my ideas on the subject there could be other factors involved as well.
Have you ever compared this kind of patch in both ways? (along grain/rectangular to grain) If not is somebody in the world to have proven by comparismn? Because just guessing is just guessing. I think this smal area wouldn´t do a difference, but the glue combined with roughness while work, would change more than the rectangular version. Your skill is perfect.
