Gun stock makers explain basic procedures for installing a machine inlet gunstock which we will be breaking into four parts; fitting, shaping, sanding and finishing. Stock makers always do gunstock duplication in this order. Never attempt to shape or finish a gun stock before fitting is complete. If you have any additional question's, we have a technician available to assist you.
If you need help finding the necessary tools and components commonly used by gunstock makers, please contact us and if we don’t have it, we can get it. Please contact us for additional instructions from professional gunstock makers and note: NOT ALL MODELS REQUIRE THE SAME FITTING AND SHAPING TECHNIQUES.

" A few weeks ago we discussed a replacement stock set for my Beretta 686. You really gave me a well deserved talking to about using inletters black. I want to say, thanks. I also want to thank you for the way you pre-machined so much of the replacement pieces. I received them Saturday, & started working on the set late morning. I finished the inletting on both the stock, & forend before supper. That inlet black is great, & made a big difference." Joe from Florida 4-2014
2. SHAPING: With butt plate, grip cap and other options installed and with all inletting complete you are ready to shape your gun stock. Gunstock makers will tell you this can generally be achieved with no more than a good set of files and a palm sander.
A. With gunstock installed onto the gun note excess amount of wood where the marriage from metal-wood is achieved. This is referred to by gunstock makers as the wood being proud to the metal. Using a pencil you can trace against the metal to achieve a line of reference. This will be helpful because shaping of the gunstock should be done with gun stock removed from the metal components. Use the appropriate files for shaping the areas to your preferred contour. Note: A very small amount of extra wood should be left for sanding.
B. Now using a palm sander using 60 to 120 grit paper finish the shaping process and remove any file marks left on the stock, be careful not to over sand around inletted areas.
3. SANDING: Sanding is a simple process of removing any imperfections or machining marks not yet removed in the prior steps. Start off with 120 grit sandpaper and a palm sander; I prefer the triangle shape because it is easier to get into small areas like flutes and around the grip. After all machine marks and imperfections have been removed switch to a 220 grit sandpaper and repeat. Finally, using a 400 grit sandpaper brings the surface to a clean consistent appearance throughout. sandpaper available for $1.00 a sheet.
4. FINISHING: gunstock makers will tell you that finishing a gunstock can be achieved with a number of different methods . In the interest of keeping it simple, for less experienced installers, we will cover only the more simple techniques. We feel that a hand rubbed oil finish is the easiest method for an inexperienced installer to use and will easily produce a beautiful deluxe finish for any grade/type of gunstock.
Apply a generous amount of Lin-Speed Oil to the gun stock part by first pouring the oil into the palm of your hand and rubbing it directly into the grain of the wood for about 2 minutes . Remove all extra oil from the part. NOTE: EXCESS OIL WILL CAUSE GUMMY FEEL. Be sure to dispose of the oil rags properly, as they may spontaneously com-bust and cause fire.
D. Touch up pens and other dyes can be found at Brownell's and help to fade repairs and other imperfects.
E. Formby’s gunstock re-finisher is a great way to remove most finishes from one part when matching to a new part. NOTE: it is always best to remove old finish to get to raw wood so the new part can be matched. Good for gunstock refinishing.
F. Pilkington spirit stain used in stock making.
1. FITTING: When fitting a gun stock, regardless of the model, it is always best to start by closely comparing your original part to your new machine inlet part. Often small ridges and machining imperfections can be noted and cleaned using whatever appropriate scraping tool or file the application would require. A common practice by stock makers and gunsmiths.
Note: a rotary grinding tool i.e. Foredom or Dremmel, while not mandatory, is an excellent advantage for any gunstock installer. Also, in addition to, a good assortment of small files (needle files) and standard size files, we recommend an assortment of stock makers chisels and scraping tools, which can be found in starter sets at most suppliers. Also, a good soft jaw bench vise to hold your project secure. Also, you will need inletters black which can be purchased for $10.00.
