I've begun work on the silver wire inlay for the handle of the gun. I simply drew the patterns on the wood with a pencil to start off with:
The tools I'll use for the job: a tiny hammer, wire cutter, a custom widening tool made from a screwdriver, a scalpel, some tweezers and a file.
The process is as follows: first cut the line with the scalpel to prevent cracking of the grain when using the widening tool, depth of cut may vary occording to wire thickness:
Next use the custom tool to very gently widen the initial cut to fit the desired wire by pressing down into the cut, corner first with a rolling motion. This allows for slight corrections in direction if the tool isn't hitting the first cut properly.
Next flatten the wire on a suitable surface and roughen the flat sides of the wire with a file. This wire is 0,7mm thickness, flattened to about 0,5mm.
Cut a suitable lenght of wire, file the ends flat and fit it into the cut. It should fit somewhat snug and stand straight up in the groove much like a nail.
After all this, hammer the wire into the wood, all the while checking that there is no sideways fumbling or bending of the wire. Here's where I ended up after about three hours of work:
After the whole patterns is done, water should be applied lightly on the wood to swell it, gripping the wire tightly in the process. Applying some heat with a hairdryer to dry the wet surface will improve the end result too. Then just use fine sandpaper to make all the wires flush with the wood.
This really gives you all new appreciation for jewelers and other fine craftspeople. Inlay takes a LOT of concentration and time with not a much room for error.
