Here are some various methods of clamping broken scrolls. Basically if you can align everything up using your hands you can figure out some way to apply pressure in this or that direction. If it doesn't line up, then you might need to glue parts of the scroll for several days in a row. I had one scroll where I needed to glue it in three different sections. I usually use a combination of clamps and or rubber bands or string. Each scroll is different so you need to find the best solution.
Here is a violin scroll where the break went through 2 peg holes. Then the various steps of installing a spiral bushing and an inner sleve are listed below.
- First practice dry clamping the scroll. Once you get a method to clamp the scroll where it's as perfect as possible, then proceed to the gluing step.
- Glue the crack. Usually I use the existing peg or pegs to help align the crack and to keep it from shifting under clamping pressure. Remember to wrap the peg in plastic wrap so it doesn't get glued to the scroll.
- For this violin scroll I wanted to make an interior sleeve.
- The first step of the sleve, is to use a similar size material and line the inside of the peg box. Then put plastic wrap inside and cast the piece and let it dry for a day.
- Fit your spiral bushings.
- The next day trim them off. Usually on the outside of the peg box, I protect the scroll with some masking tape or painters tape. Then I use a gough to trim off the excess to the thickness of the tape. Remove the tape and then carefully thin the remaining spiral bushing.
- The cast piece now needs to be cut in half using a band saw.
- Make a template for the fiber.
- Bend the fiber by using wedges and clamps.
- After it's dried for a day you can trim it up a little and it's ready to glue into the peg box.
- Use the same technique to glue the formed fiber piece into the peg box. Wedges and clamps.
- Cut the hole out.
- Normally at this stage I fit the original peg to the new hole diameter, but in this case I needed to fit the hole to the peg since they were mechinacal.
- Do a little bit of varnigh touch up to hide the parts where the varnish chipped off when it broke.
Here is a scroll that was repaired by another shop. They glued it together and then put several wooden pins around the peg holes. When he brought it to me, it wasn't completely apart, just the cracks had opened up. This was somewhat difficult to fix because of the previous repair. Oops, I can't find the other photos of this scroll, but I was able to glue it together and then did a spiral bushing on just the "A" peg hole.

Here is another broken scroll. The trick to getting a scroll break to kine up is by using the correct clampling angle.
Although this is a really cheap student violin, they wanted it repaired and even so I still try to do my best work. This is an example of using braces and rubber bands to glue it together.

This is a shot of a scroll that was broken once before and repaired by another shop. Then it broke again in a slightly different spot and was basically totally sheered off. These are the bofore photos, but I can't seem to locate the after photo, but it's nearly invisiable.

Here is another scroll that was broken, this type of break is more typical. If it goes through one of two peg holes they need to be bushed with a spiral bushing. The bushing keeps the peg from expanding the peg hole and opening the crack.

A cello scroll that was broken through the "D" peg hole.

This is a crack in the scroll that did not go all the way through, but it needed a lot of clamping pressure to get it completely closed.

A violin scroll that's broken just where the neck starts, it's a very short break so I needed to put in two stainless steel pins under the nut.

Here is a violin that has a bad crack running through most of the scroll. It had custom made brass plates that were screwed onto the sides. The crack was completely open and only the plates were holding it together.
