Lean Pipe Workbench Assembly Guide – From Start to Finish

Think of this as the foundation of your workbench. Grab two long lean pipes (usually 120cm or 150cm, depending on your model) and two shorter ones (60cm is standard for width). Connect them using 90° lean pipe joints to form a rectangle.

Here's the trick: ｉｎｓｅｒｔ one end of a long pipe into a 90° joint until it hits the stop. Then do the same with a short pipe on the adjacent side of the joint. Tighten the joint's set screw with your Allen wrench – not too hard, just until it's snug. Repeat for all four corners.

Now, stand your rectangle upright (you might need a helper for this part). Screw a vertical lean pipe joint onto each corner – these will hold the legs that lift your workbench to waist height. Slide a vertical pipe (usually 80-90cm) into each joint. Again, just snug the screws for now.

Pro tip: If your kit includes internal rotary aluminum joints, save those for parts that need flexibility (like adjustable shelves). For the base, stick with fixed 90° joints – they're sturdier for weight-bearing.

Flip the base frame upside down so the vertical legs are pointing up. Take your caster install base (a flat metal plate with holes) and align it with the bottom of one vertical leg. Use the screws provided to secure it – hand-tighten first, then give it a final twist with your Allen wrench.

Do this for all four legs. Pro Hack: If your casters have brakes, put those on the two legs that will be at the "front" of your workbench (where you'll stand). That way, you can lock it in place easily while working.

Now, line up the stem of each caster wheel with the hole in the mounting plate. Push firmly – you should hear a "snap" when it's seated. Give it a gentle tug to make sure it's locked in. Repeat for all four, then flip the frame right-side up. Wiggle it a little – if it rocks, check that all casters are fully seated.

Using the same method as Step 1, build another rectangle with your remaining long and short lean pipes. This time, connect it to the top of the vertical legs using – you guessed it – 90° lean pipe joints. Once it's in place, grab your level and check if the frame is square. If one corner is higher than the others, gently push or pull until the bubble is centered.

Here's where the 45° lean pipe joints come in. Cut two shorter lean pipes (measure diagonally across the lower frame to get the right length) and connect them from corner to corner, forming an "X" on the bottom frame. Do the same for the top frame. These braces prevent the workbench from swaying when you lean on it.

Now, go back and tighten all the joints! Start with the corners, then the braces, then the casters. Use your Allen wrench to give each screw a ¼ turn past snug – you'll feel resistance, but don't crank until the metal bends.

Your Workbench E (single deck, without caster) should have pre-drilled holes that line up with the upper frame. Lift it onto the top rectangle (get a helper if it's heavy!) and secure it with the screws provided. Start with the four corners, then add screws along the edges for extra support. Tighten until the top feels solid – no bouncing!

Roller track is what turns a basic table into a lean manufacturing tool. Let's install a 40 steel roller track with yellow wheels (a popular choice for visibility). First, mount the aluminum guide rail A to the side of your workbench top using roller track placon mount brackets – these little brackets are designed to lock into the aluminum profile of the workbench frame.

Slide the roller track into the guide rail until it clicks. Then, add end supports with stops on both ends to prevent materials from sliding off. Give the rollers a spin – they should move smoothly, with no sticking. If a roller is tight, check if the track is bent or if there's debris in the guide rail.
