Jim,
I have used the Easy Off method twice. Here is how I did it with good success.
1) I got the disposable aluminum pan and laid my stock in it.
2) I bought a can of regular easy off. Make sure the easy off uses lye (sodium hydroxide) as the cleaning agent. I think there are others now that use different stuff for cleaning very dirty microwaves and different types of BBQ pits that do not use sodium hydroxide as the agent.
3) Spray the sodium hydroxide on in a good thick layer. I should foam up some.
4) I was told to cover it in aluminum foil as well to hold the easy off to the wood. I don't know if that is necessary.
5) Leave it to sit for 3 - 10 minutes. I would let is sit for shorter periods of time rather than longer. This way you can see how quickly it affects your finish. Leaving it on too long can damage a stock as the lye will eat at the wood too.
6) Once you have left it on for the desired time put it in a warm soapy bucket of water and rinse gently with a bristle brush to remove the goop off the stock.
7) Let it sit and dry until you can determine if all the finish and oil have been removed. If not repeat the steps.
I did this on an old 1930s A5 stock and it worked great. However, I had a couple of concerns and here they are:
1) Leaving the solution on the stock too long can eat at the wood. For my project it was not a big deal, but on a nice stock for a quality gun I would be concerned. I think Wonko's brew (acetone/alcohol) does not cause any damage to the wood.
2) The lye in the easy off puts off extreme heat and ate away at the aluminum. I would see if you could find a rubber or plastic pan that would not be affected by the easy off.
3) The successive cycles of easy off and soapy water can cause the stock to swell if it is very dry. Upon drying too fast you could get cracks in the stock. The A5 showed one small crack where the rear of the receiver fit into the stock. I filled it with acraglass when I refinished and it looked fine, but again, those types of occurances are not good for a better stock.
4) Sodium Hydroxide is nasty stuff and gives off fumes. Use heavy rubber gloves and do it outside or in a well ventilated area.
I would be interested if others have used this method and if they got the same results I did. If they did or did not can they provide solutions to the issues I found above.
I have not yet tried the Wonko's brew method, but in numerous posts I have seen people swear by it. My next stock will be with the Wonko's method for a good comparison.
