| ¡ | Sand down the area of the crack and find the start and end of it if possible. |
| ¡ | Using a very small drill piece, drill a hole at each end of the crack, if that can be determined, this will stop the split spreading any further. |
| ¡ | If you can, wedge something into the crack to open it up a bit or widen it slightly with a knife to allow room for some filler. It is usually better to fill the space, created by the crack, with filler rather that try to glue the two parts of the crack together and taping it up. |
| ¡ | Filler : mix some quick setting epoxy resin glue, pva wood glue or better still, some Aliphatic (yellow wood glue), with some sawdust into a paste and press it into the crack and drill holes. If the instrument is not painted try to stain the sawdust with some wood stain, prior to mixing with the glue, this will disguise the repair as best as possible. If it is a hairline crack that closes completely once the wedge is removed, dispense with the sawdust and just use the glue on its own. If the hairline cannot be opened up just rub the glue into the crack with your fingers |
| ¡ | Remove the wedge, if used, and scrape of any excess glue that has been squeezed out when the crack closed up, do this quickly before it sets. |
| ¡ | When dry, rub down smooth and seal the outside with some pva or wood glue. Allow the repair to harden for a few days then oil the inside to help protect against further cracking. |
| ¡ | Now's the time to re-paint. If is painted in ochres you may need to enlist the help of your local art shop or search the internet to get the correct pigments. If it is acrylic then contact me and I may be able to help with the colour choices. A gloss finish can be replicated with a thin coat of wood glue, pva or acrylic silk or gloss varnish. A matt finish will result from the painting or can be obtained from a flat matt acrylic varnish applied after re-painting. Do not use "normal" varnish as it is probably cellulose based and will lift the original coating and paintwork! |
| ¡ | Thats it! all done Good as new!!. Wasn't that bad was it? |
| ¡ | Before starting to oil your instrument check it over very thoroughly for any hairline cracks, especially around the mouthpiece, or pinholes. This is very important, especially so if it is painted in ochres as any seepage will spoil the appearance of the artwork or destroy a section of it completely. If you do find a leak seal it as described on this page. |
| ¡ | My method involves sealing up the mouthpiece end of the instrument and can be used with a natural or wax mouthpiece. To do this you will need one or two (depending on the size of the mouthpiece) old supermarket carrier bags which you will need to roll up into a plug. I flatten out the bag, fold it over a few times until you have a long strip about 2 inches wide. I then roll it up as tightly as I can until I end up with a cylinder shaped plug which is slightly bigger in diameter than the mouthpiece aperature. If it isn't then add some more polythene to the plug. |
| ¡ | Push the plug into the mouthpiece with a twisting motion, it should be fairly tight, pressing it in until it looks sealed. It doesn't need to go in all the way, about halfway should do it, remember, you will need to pull it out again!! Be extra careful with very thin walled instruments!! |
| ¡ | Now you are ready to pour in the oil. To start, stand the instrument up and pour a small amount of oil into the instrument via the bell end. Check that the mouthpiece end is leak free. When you are satisfied that all is ok, pour in the rest of the oil. don't be shy, pour in more that you need. |
| ¡ | Now carefully roll the instrument around to distribute the oil, keeping the bell end raised slightly to avoid any oil dripping out of the open end. I shine a torch down the bore whilst doing this to make sure the oil has covered the entire bore. |
| ¡ | To finish off I use a small paintbrush to spread the oil right to the end of the bell, this avoids oil dripping onto the paintwork, as it might do if the oil was allowed to run naturally down the bore to the bell end. |
| ¡ | Finally, tip the didjeridu, bell end downwards, to drain the oil back into it's container. Hold it for a few minutes until the drips almost stop. I then stand my instruments on a strip of wood which spans an old saucepan to allow the rest of the oil to drip out overnight. wipe of any excess with a bit of tissue, pull out the plug and job done!! |
| ¡ | For the next few days stand the instrument on a thick piece of cardboard covered in tissue or kitchen roll just to ensure all of the oil has finished dripping out. |
