Here is one recipe if you want to make it yourself:

Boiled linseed oil – 16 oz
Spirits of turpentine – 2 oz
Carnauba wax – 200 gr
Venice turpentine - 2 teaspoonfuls
Mix together and heat until it simmers. Simmer for ten minutes then allow to cool.
Be careful it does not catch fire -!!!!


However, Napier produces a ready-mixed formula in a neat little box with all the odds and ends to get you started. These kits are available at gun shops and save a lot of mess and smell. I find the Napier bottled oil works very well if used properly.

First prepare the wood - as with any job, the preparation will govern the finished result, so go back to the bare wood, restore the shapes and angles if need be and raise or fill any dents or gouges.

Apply red-oil (turpentine & bolied linseed oil in which alkanet root has been steeped.

When the colour is right, it depends on the wood how many coats this will take.Apply two coats of finishing oil with the palm of the hand sparingly – it will be absorbed. Remove any excess gently with fine wire wool, buff with a lint-free cloth (not a woven one) and then leave for two days before you apply a clear grain-filler, allow it to dry thoroughly and then rub it gently with fine wire wool.

Now begin the finish – this must be built up gradually in VERY thin layers. Rub the finishing oil in with the palm; use half as much as the minimum you think necessary. Do not leave any sticky residue on the wood, rub the oil into the wood until you feel it get hot in your hand. Leave a day between each coat and expect the process to take four or five weeks before it is finished. The results are surprising and pleasing, making all that work worthwhile.

Don't be afraid to cut the finish back with a little oil on a pad of fine wire woolwhen necessary - even half way throuh the process. This will ensure that the finish is smooth and it flattens out any indents where the grain may show. You want the finish to be smooth, flat and even.



Unfortunately, I do not believe you can easily find Napier in the US. However you can find slacum oil as part of the Purdey Warthog kit: http://www.jeffsoutfitters.com/store.aspx?panel=3&productid=176&categoryid=1

Thanks for the formula Spott3r.I have been using the warthog kits for many years and they are great indeed but are pricey.Your procedures are very close to mine.
Lately I have been asked to do a lot more of this finish on new stocks as well as refinishing jobs and I need to lower my cost by either buying in larger containers or making my own.

Please note this is Pete's version of the mixture. It is probably not Purdey's concoction. Similar but not exact.
 
anyone know what temp, I need when heating the mixture? Got all the stuff needed today after traveling all over Raliegh all day.
It will have to be put on hold for a few days as I am going into surgery tomorrow for removel of a cancer in my bladder.The doctor feels it is only a level T 1,Hope so.
regards to everyone.

Chuck, I have always just kept it from smoking myself, never used a thermometer, if it smokes, back the heat off. I find it works best soaking in on the first few coats when it and the stock are both warm.

I wish you the best fastest recovery!
