Old Pipe Wrench Restoration: From Flea Market Find to Good As New

If you're a DIYer or a handyman, you likely know the importance of having the right tools for the job. And when it comes to plumbing, a pipe wrench is an essential tool to have in your toolbox.

However, if you've got an older one, it may not be in the best shape anymore. And let's face it, having equipment that's clean and accessible makes it a lot more motivating - and enjoyable - to get work done around the house.

In this Instructable, I will show you how you can restore an old tool like this to its former glory, using some patience and elbow grease. It's a really easy restoration project, and it can be done in a single weekend if you've got all the supplies.

Old pipe wrench

Alcohol wipes or acetone - for degreasing before painting

Chemical paint stripper

Protective gloves

Medium-bristle brush

Vinegar or rust-removing solution

Wire brush

Steel wool

120-grit sandpaper

Painter's tape

Rust-inhibiting primer

Spray paint

Here's a quick video about the restoring process.

Like with any restoration project, we first need to disassemble everything in order to get access to all the surfaces that need cleaning.

To take the wrench apart, turn the knurl (the cylindrical piece) to bring the jaws apart. Continue turning until the hook jaw comes free from the handle. The knurl should then fall out by itself.

There is also a small spring inside the handle called a flat spring. It could also be removed from the tool with long-reach pliers and changed out (replacements for these usually don't cost very much). However, as the spring in my wrench still worked perfectly, I left it in place.

For the next steps to work, we first need to remove the grime and grease from the tool's surface using some alcohol wipes. When using WD40, keep in mind that it will leave an oily protective layer on the metal, which could cause problems when painting the pieces later on. So acetone and alcohol are always a safer bet, as they will evaporate and leave a clean surface.

The old paint can be removed using a heat gun or some chemical paint stripper - the latter being far easier and quicker to use, especially around the little details like the lettering.

While wearing gloves, carefully cover the object with paint stripper, being careful to not get any of it on your skin.

After 10 minutes, the paint will be soft and malleable. You can remove it using a soft fabric cloth, or a medium bristle brush if the surface is going to be painted and you're not afraid of scratching it.

Repeat if necessary, until you get down to a bare metal surface

We can now start cleaning away the rust.

Soak the parts in vinegar for a day, or a rust-removing solution for the time prescribed by the manufacturer (leaving metal in these solutions for too long can actually damage it).

Then, use a wire brush or steel wool to scrub off the rust and the last traces of paint. Make sure to also clean the little teeth on the hook jaw.

A quick test to see how good of a job you have done cleaning your tool is to press some strong tape onto the side of your tool and then pull it off. That will highlight all the areas that are still covered with rust and other dirt - it's very important that you take care of them before painting, as otherwise, the paint will start chipping away from the tool very soon.

Now is also the perfect opportunity to address some of the casting defects, if you feel like it. Using 120-grit sandpaper, smooth out any sharp edges. A power tool is best for this, but of course, it can also be done by hand.

Pipe wrenches often have some parts that are non-painted and finished by sanding - that was also true for this model made by Rigid in Ohio. The jaws themselves as well as the flat sides were originally left bare.

To get the same finish back, rub the metal on a flat piece of sandpaper in a straight line back and forth, to get back those signature parallel lines on the metal. A belt sander could also be used, but any rotating sander will mess up the result.

Mask out all the metal you just finished sanding with some painter's tape, to prevent paint from sticking to it.

If you decide to also paint the knurl, block off the sides with tape to make sure no paint interferes with the tolerances of the mechanism.

Now that all the details have been cleaned and sanded, comes the most satisfying part: the painting.

To be extra safe, you can first apply a coat of rust-inhibiting primer. Then, apply a coat of your desired color to the tool - I went with red and black, to match the original colors of the Rigid tool.

It's very important to go slowly with this step, and avoid applying too much paint to the metal - otherwise, there will be ugly cracks and ripples as it begins to dry. I applied only two coats: a normal one for the first layer and a thin second one, to touch up any parts that weren't painted properly the first time.

PS: To make painting easier, you can hang the parts by a string - that way you'll have access to them from all angles.

Leave the paint dry for around an hour. Then, while the paint is still malleable, remove the masking tape.

Then, leave the paint cure for a few days so that it hardens completely.

It's now time to put everything back together again. First place the knurl back in place. Then, insert the hook jaw and turn the knurl until the jaws touch again.

And just like that, you now have a fancy pipe wrench that's back in perfect condition. Restoring tools can be a satisfying and rewarding task, and I hope I managed to inspire you to take on a tool restoration project yourself - it really is easy if you follow these basic steps.

As for any improvements to this project, I think I would use a rust-inhibiting primer and metal spray paint for all the details if I ever had to redo this project. I also painted the knurl by accident - in the original configuration, it doesn't have any paint on it. So, a few things I would change, but overall I'm really happy with how this turned out.

Thank you for reading my Instructable. I hope it will be helpful to you in restoring your own wrench or any other similar tool.
