Step 1: Materials
Find two pieces of pipe and cut to desired lengths. One for the handle (thicker), and one for the wire holder (thinner). Some screws, washers, stainless steal wire and a piece of rounded wood.
I used a piece of copper pipe I had laying around and another from a broken wind-chime.
Step 2: Handle
Grind down a piece of wood into a circular shape just a bit larger (and slightly cone shaped), than the diameter of the handle. Using a hammer, force the wood inside one of the sides of the handle being careful not to damage the pipe and cut off the excess wood with a hacksaw. Next, using a grinder, grind off excess wood and shape the end to accommodate the thin pipe.
Step 3: Wire Bar
Gently secure the thin pipe in a vise and drill a small hole at the center all the way to the other side. Next, drill one side a bit larger to accommodate the head of a 2" long screw. Next, drill a small guide hole in the center of the wooden plug on the handle.
Step 4: Attach Wire Bar to Handle
Step 5: Attach Wire
Drill two small holes at the top of the wire bar (one at each end).
Note: I happened to have a spare replacement wire from a broken store-bought cheese slicer which made attaching it a bit easier for me. (Perhaps they can be purchased: http://www.oxo.com/p-735-wire-cheese-slicer-replacement-wires-3pack.aspx).
Insert a screw at one end and if necessary, using a small disk grinder, make a small slit on the screw head and also on the sides of the pipe. At the other end, attach one end of the wire with a screw. Next, stretch wire across the bar, over the screw slit and around the end of pipe. Drill a small hole at the underside of the wire bar and insert a screw with two small washers three quarters of the way in. Stretch the wire again over slits and once around the underside screw between washers and tighten. Finally, drill a tiny hole on side of handle to attach lose end of wire with tiny screw. (see photos)
