Well I made a wood stock and grip for my AR 15. Began by cutting a wood section with a chain saw from a tree in the back yard. I made the first stock and then drilled the hole and the hole wandered off. Trash. Next stock same deal. #3 went a bit better but the learning curve was not finished yet. I decided to use a good sharp padle bit to make a 1 1/4" hole for the gas tube while the wood was still in the stump. I then took the chain saw and cut it out and shaped it with an angle grinder and sanding pads. I went to fit the stock to the gas tube and had to grind more out of the stock for the lower part of the tube. I used a sawzall for that and I also used the angle grinder to remove most of the lower section of the gas tube. The tube is used for an adjustable stock and is aluminum. OK I got it fitted and it is snug. OUCH there is a retaining nut on the gas tube. I need to make the entry hole in the stock larger to go over that nut. That is done fits well. I put the upper onto the lower. MORE Learning Curve! My stock is too tall and I can't pull the charging handle back! I pull the test fitted stock and more shaping with angle grinder. AAAHHHHH!!! Too thin and I windowed the top of the stock. And the small rustic looking hole that black ants made in the wood is not a huge canyon. No wood dope so I used super glue and sawdust. I decided to make an oak spacer and cut 3/4" off the front of stock so no more window in it. Shape and sand it all and stick more stain on it. Stain is not darkening the wood enough so out comes the torch to burn the wood slightly. Much better. All fits well soooooo I got out the JB weld. The gas tube is solid and in the correct spot and nut is tight I slip the 3/4" spacer over the nut. But not before I stuck JB weld on the nut. I also JB welded the wood stock to the gas tube. Let dry 24 hours and sand and final shape it and last bit of stain. The pistol grip I made on first try and made it a wee bit too thin at the back. Learning curve there also . I will leave it as is for now and shoot and hunt with it and see how it holds up. I removed moisture from this wood by microwaving it a bit. Pictures.
