Decided to restore an old monkey wrench. The patina looked awesome on this so I tried my best to preserve it. I think it turned out alright!

Supplies

Tools:

drill press

belt sander

file

wire wheel

vice

dremel with a scotch brite wheel

Material:

wood for handle

epoxy

Birchwood Casey gun blue

boiled linseed oil

paper towel

Evaporust

Step 1: Disassembly

Simple disassembly. The wrench is held together with a nut on the bottom. In this case I had to sand down the end of the wrench to remove the ceased nut.

Step 2: CLEAN PARTS

Place parts into a tub of Evaporust. Leave in for 24 hours.
Remove and wipe clean with paper towel.
Any remaining rust removed with a wire wheel.

Step 3: Restore Wrench Surfaces

Use a belt sander to clean up the wrench. Remove any mushrooming and larger dings.
File the work surface of the wrench jaws flat.

Step 4: Bluing Surfaces

Using a scotch brite wheel on a dremel, brush the entire surface of the wrench. This helps bluing to have a nice consistent finish.
Wipe wrench parts with acetone.
Apply bluing all over.
Rinse parts with water.
Now to seal the bluing, apply oil to the wrench and let it sit for a few hours.
Wipe clean.

Step 5: Make Wooded Handle

Select a piece of wood and cut to length with a mitre saw.
Drill hole through the wood.
Cut chamfers on all corners of the wood with a table saw. This removes most of the material making it easier to round edges later.
Remove more material (round the edges) with a belt sander.
I used my drill press as a make shift lathe and mounted the wooden handle into it. I then completed the final shaping/sanding in this step. See video for more clarity.
