Power Washer Cart

Introduction: Power Washer Cart

I ended up getting a high pressure power washer, originally used for a small car wash.

Since it wasn't portable, I had to change all of that by building a metal cart to wheel around my driveway and property.

This project was made at TechShop Austin-Round Rock. www.techshop.ws

Step 1: Cutting the Base Frame

First step for me was to cut the metal tubing to create the base.

I cut the 1" by 2" rectangular tubing to run left to right, and then used 1" by 1" square tubing to go on each end.

I used the cold saw to knock the cuts out.

The 1" by 2" pieces ended up being 20" long, with the 1" by 1" pieces going about 17".

(These measurements were what was needed with my power washer. If you have a different sized washer, these measurements would need to be adjusted!)

Step 2: Welding the Base Frame

Now that my 4 pieces are cut, I needed to MIG weld them all together.

First, I clamped and squared off the bars. Then, I welded the pieces together!

I used an angle grinder the clean up the welds afterwards.

Step 3: Predrilling Holes for Mounting the Power Washer

I set the power washer onto the base frame, and marked the holes to drill out for it all to bolt together.

Step 4: Adding Wheels

To add wheels, I needed something for the axle of the wheel to slide through.

I had a few 3" square metal plates lying around with predrilled holes in each corner.

I welded these plates onto the side of the base frame, to create a tab for the wheel to slide through one of the existing predrilled holes.

Step 5: Cutting/Welding the Legs

Once the wheels slipped onto the tabs on the back, I needed to make front legs.

I used the 1" by 1" square tubing to make it.

First, I leveled out the frame with the wheels installed to determine the length.

Then I went over to the cold saw and cut them down to size. The second leg had a little burr on the end so I cleaned it up with a bench grinder.

I had come across some end cap plugs for the bottom of each leg.

Then I welded the 2 legs onto the frame!

Step 6: Building a Handle

For the handle, I eyeballed the lengths and created/welded together a handle bar, with a hook to hold the cord.

After that, I hit the whole frame with a can of black spray paint to finish her off.

Step 7: All Done!

That's all she wrote.

    I appreciate the tips and photos! I recently got a Tecumseh HMSK80 from some neighbors and the only issue is the surging which I'll address later.
