Every home handyman, builder and cabinetmaker should have a case to protect their tool-sharpening oilstone.Every home handyman, builder and cabinetmaker should have an oilstone case for keeping their tools in tip-top condition. Stones are fragile and can break or chip easily, but an oilstone case can protect your stone from unfortunate mishaps, as no good tradesperson should have to blame their tools.

Step 1 - Measure and cut the piece of 150x25mm timber to length about 35mm longer than the oilstone at either end, then measure and cut the 150x25mm in half to make two pieces 75mm wide to achieve a base and a lid.

Step 2 - Centre the oilstone on the base piece first then trace a line around the stone and repeat this process for the lid. Screw down four pieces of scrap wood the same height to secure the base.

Step 3 - Set the router to recess about half the thickness of the stone, then measure and screw a piece of timber as a guide to run the router along at equal distances along the inside of the lines.

Working the router lengthways with the grain remove the remainder, stopping just before either end of the line and finishing to the line.

Step 4 - Tidy the corners using a sharp chisel. The stone should now fit comfortably into the recess without movement and with about half the stone protruding. Now repeat the same process for the lid.

Step 5 - With the oilstone fitting and no gap between the base and lid, turn the lid over and use a decorative moulding router bit around the top outside edge to give it a nice finished look.

Step 6 - Use 120g sandpaper to tidy up and smooth, ready for a coat of sealer.

Tip: Make sure you have a snug fit. Any gap will allow the oilstone to move when sharpening tools.
