For a boat building or repair job to turn out best, it's important you use high-quality products. A mixture of five parts 105 Resin to one part 205 Hardener provides a 9-12 minute pot life and 60 to 70 minutes of working time as a thin film. The base material of most WEST SYSTEM compounds, 105 Resin is formulated without volatile solvents or odor and has a relatively high flashpoint, making it safer to work with than polyester or vinyl ester resins. Slower set epoxy with around 1 hour set, gives strong bonds and unlike superglue it fills even large gaps! In the event of wood splitting or cracking on a didge I am making, or on a didje I have made or bought I will assess the problem and determine what the most appropriate repair would be. Once cured the resin is like a plastic, it will expand and contract well alongside the wood, the breaking strain of the bonding strength is over 1 ton (for repairs the resin I use has a 2 ton breaking strain ((evidently)).
There a large number of different epoxy resins on the market, all with slightly different yet similar properties. Rubber gloves are a must as the resin is toxic until cured and will cause severe skin problems. Other bits and bob's you will need are a little container to measure and mix the resin (they can be reused), a mixing stick or brush - I use a McDonalds stir stick.
As I have stated above, resin is toxic until cured and is extremely unpleasant - follow thw manufacturers instructions exactly and you won't go wrong. Epoxy resin cures by way of exothermic reaction, in other words it heats up when the chemicals are mixed. I lay it on thick but you don't want to have to replace a carpet with a great big hole in it from uncured tipped over resin! Mix thoroughly but try to avoid too many air bubbles as they can set in the resin and weaken the repair, however you will end up with a few when stirring the mix. When the repair is large you may want to consider adding filler to add more body to the resin. Always follow the manufacturer's instructions as they will include what consistency and ration you need to mix everything together.
If you add sawdust to the mix, the epoxy resin will make the colour of the dust change in the same way varnish does when coating bare wood ie.

Ok, now the resin is mixed, the didge is secured in place, I will use the stir stick to drip the resin into the repair. To remove the excess cured epoxy resin a file is about the best implement to use as a wire brush will remove any clogging.
Once the bulk of the excess is removed, I use sandpaper then wet and dry to end up with the finish I want.
WEST SYSTEM® 105 Epoxy Resin and 205 Fast Hardener combine to form an excellent material for making strong structural bonds, applying reinforcing fabrics, and barrier coatings that will stand up to harsh marine environments. It will wet out and bond with wood, fiberglass, reinforcing fabrics and metals.  This epoxy cures to a rigid, high-strength, waterproof solid in six to eight hours at room temperature, and will cure at temperatures as low as 40°F. Taking care of your didge will help prevent such problems as splits and cracks but it will NOT stop them. Having experimented with a number of products and techniques I have settled on using resin for a number of reasons, in a nutshell: strength, durability, aesthetics, versatility, and water resistance. What ever type you choose I would recommend you look for several qualities: i) curing time, if it is less than 15 minutes you may not have time to apply it to the didge.
The actual repair will only take a couple on minutes but will need to be left flat to cure. Many splits run further than any visible gap so it is always an idea to effect a repair on a larger area than just the damaged bit. Unlike other products that set when two parts are mixed, resin will only set if the correct quantities are mixed - it will not set quicker by adding more hardener (believe me it is really, really difficult to clean up uncured resin). Most resins come with instructions as to recommended fillers such as very small polystyrene balls. I invariably use the dust produced from sanding the wood in the first place is good enough, but also have a collection of different coloured sawdust from a range of species of wood so I can match with the wood of the didgeridoo. If the area is large I may pour it in but normally don't like to do this because it's too easy to spill. Firstly, using a pin to prick the bubble and break the surface tension, and secondly using a hot-air dryer or paint remover hot-air gun to gently heat the resin.
I'm not superstitious but always try to veer on the safe side and allow a little extra time for curing. Sandpaper will clog very quickly and become useless, power tools will heat the resin up and melt it, again clogging up the disc or pad etc.

It can be sanded smooth and shine with a gloss finish or a slightly rougher surface to produce a matt or vinyl finish. If the curing time is to long the resin will run and sag as gravity pulls it round and down the didgeridoo.
Try to avoid latex and go for vinyl - as vinyl does not have powdering coating and therefore will not contaminate the resin (also a number of people have allergies to latex). Using a sharp blade (Stanley knife or similar) work the split or crack on your didgeridoo so that it is open. As it is far easier to file and sand down than have to wait and apply a miniscule amount to a little air hole. Heating the resin will make the liquid (now turning to gel) more runny an lose the surface tension it had. I have written a new cookies policy, which you should read to find out more about the cookies I use. The aim is to provide a surface with a texture that the resin can adhere to and has the added advantage of revealing the full extent of the damage to be repaired.
Heating the resin will also speed up the curing time by augmenting the exothermic reaction. Any supplemental layers added after the resin is cured will be a completely separate layer. For a vinyl effect finish up 400 - 600 grit wet and dry and for a gloss finish up to 2000 wet and dry. It can be combined with additives to change the colour and consistency making it possible to affect larger repairs etc. Further layers added when the resin is still tacky (just before it fully cures) then the subsequent layer will mix with it to become one solid mass.
For didges that are being completely refinished I will leave the resin at 120grit then sand it along with the rest of the wood.
