Sand‑In Gunstock Finishing Technique as used by the gunmakers at TAG and ASA.
This method uses fine abrasive dust and oil to create a slurry that fills pores and produces a deep, traditional English finish.
Prepare the Stock Surface
A clean, open‑pore surface ensures the oil and sanding slurry can penetrate properly.
Ensure the stock is fully stripped of old finish
Sand to 220–320 grit depending on wood density
Remove all dust with a tack cloth or compressed air
Apply a Thin Coat of Oil
The first coat provides lubrication for the abrasive and begins penetrating the grain.
Rub a small amount of oil into the wood with your palm
Warm the oil by hand friction for deeper penetration
Do not leave excess oil on the surface
Wet‑Sand With Fine Abrasive
Key Step
Sanding creates a slurry of oil and wood dust that fills the pores.
Use 400–600 grit wet‑dry paper
Sand with the grain using light pressure
Allow the oil to mix with the sanding dust to form a paste
Work the Slurry Into the Grain
The slurry fills pores and levels the surface for a smooth, traditional finish.
Push the slurry across the grain to force it into pores
Continue until the surface feels uniformly smooth
Add a drop of oil if the slurry becomes too dry
Remove Excess Slurry
Removing surface residue prevents streaks and ensures an even cure.
Wipe gently with the grain using a clean cloth
Leave only what remains in the pores
Do not buff to shine at this stage
Allow the Coat to Cure
Dry Time
Proper curing builds depth and durability in the finish.
Let the stock rest overnight or 12–24 hours
Ensure it cures in a dust‑free environment
Avoid touching the surface during curing
Repeat for Depth and Smoothness
Multiple sand‑in coats create the classic English hand‑rubbed finish.
Repeat steps 2–6 3–6 times depending on pore size
Switch to 800–1000 grit for final coats
Stop when pores are filled and the surface is glass‑smooth
Final Wax or Oil Topcoat
A final protective layer enhances sheen and seals the finish.
Apply a thin coat of stock wax or finishing oil
Allow to haze, then buff lightly
Maintain with occasional waxing
