Heavyduty Workbench / Shop Cart





Introduction: Heavyduty Workbench / Shop Cart

Good Afternoon y'all, Mrs. Gnome has been requesting that I do something with the garage. I suppose tools and jugs of used motor oil lined up against the wall are not cool enough for her? Oh well happy wife happy life.

I have been tinkering on a salvaged wooden teacher’s desk in our utility room, but I need an actual workbench. In addition to being a sturdy base for banging on stuff; I wanted 2 adjustable lights (one with a magnifier), a minimum of 4 x 110v outlets, a small vise, and storage for my larger tool boxes. I also wanted the ability to roll it around when I am working on something big, like a car, so that I can swing the lights over the engine bay.

Like most of my projects I tend to overthink them, and write it in a little notebook. I keep doodling away until I get the time and money to work on them. I started with the sketch above, although I deviated as I went, the end result wound up being both functional and good looking.

I should warn you I went pretty picture heavy if anything brings a question to mind feel free to ask in the comments.


ANSI rated safety glasses and a dust mask; you are only issues 2 eyes it is up to you to protect them. If you forget this stuff and hurt yourself then I can't help ya.

If I had my wish I would have used a miter saw and a reciprocating saw for squaring up the 2x4’s. I am more than happy with the end result. All in all I spent about $200 on this project but it holds up to me jumping on it, so I guess that classifies it as heavy duty. I am a big guy. and the lowest rated part are the wheels at 600lbs each.

Step 1 Clean a space for the bench and gather your parts, tools and safety gear, you are going to need a bit of space to work with. I happen to have the rare occurrence of a perfectly flat and level garage floor of smooth concrete. I built up using the floor as my plane of reference. If you are not so lucky then use the table top as your reference point. Or any flat smooth surface.

Step 1: Framing the Top and Bottom Horizontal Supports

I am going to state early that every screw hole that I use, I drill a pilot hole to prevent the screw from splitting wood and ripping out. Also this may seem like overkill but I sand all surfaces with 100 grit on a 1/4 sheet sander, and align every piece joined together with the squares. I like having a tight fitting joint and the extra time in fitting makes up for it with a nicer finished product.

Unless specified i used the 2¾" screws.

Measurements: The table top is the hard component that cannot be modified so I altered my design to it. The dimensions of the top are 30” deep by 60” wide. I needed a 8” over hang on the right side for my vise, so that gave 52 inches to work with. I left a 1 inch overhang on the left side to allow clamping space. And I am using US standard measurements. Sorry rest of the world they only sell wood in inches and feet in the US.

Cut four sections of 2”x4” into 4 - 48” lengths

Cut four sections of 2”x4” into 4 - 30” lengths

I used a butt joint, and 2 2¾“ screws per end, with the 48” lengths inside the 30” pieces, resulting in a box 51” by 30”.

From Wikipedia “The butt joint is a very simple joint to construct. Members are simply docked (cut off) at the right angle and have a required length. One member will be shorter than the finished size by the thickness of the adjacent member. For enclosed constructions, such as four-sided frames or boxes, the thickness of the two adjacent members must be taken into consideration. For example: when constructing a four sided box made from 19mm thick material that is to be of finished size 600mm x 600mm, two of the members will be docked at 600mm and two will be docked at 600mm - 19mm - 19mm = 562mm.”


Step 2: Framing the Legs

I wanted my bench to have 4x4” posts for legs, but I also wanted to be able to make it with the tools that I have on hand. I wound up notching the inner 2x4 with a "Top Post Tenon" on each end and laminating a shorter 2x4 in place using glue and screws. This will result in a piece almost as strong as a single post but without the expense of a 4”x4”.

For this section you will require 4 - 30” lengths of 2”x4” for the inner legs and 4 - 23” lengths for the outer legs. The inner legs will have a top tenon cut in them measuring 1½“ deep 3 ½“ long, to match the frame for the top and bottom.

I clamped all 4 legs together and marked them along the short edge 3 ½” then made a 1 ½” deep cross cut on all 4 boards then I up ended the posts and made another cross cut to start the 3 ½“ that I then finished by hand. These cuts worked out rather well as you can see by the pictures. I touched them up with the sander then clamped and screwed them into place at each corner after leveling and squaring the legs. I used 2 screws on the front face and 1 screw on the side.

After the inner portion of the legs was installed I double checked fitment of the 23” sections sanding them to ensure a tight fit. I applied a liberal amount of glue to the inner leg. Using a dead blow mallet I seated the outer leg piece into place for clamping and screwing. After the 4 screws were inserted I removed my clamps and went onto the next leg.


“The mortise and tenon joint has been used for thousands of years by woodworkers around the world to join pieces of wood, mainly when the adjoining pieces connect at an angle of 90°. In its basic form it is both simple and strong.”

Top tenon - “the tenon that occurs on top of a post.”

Step 3: Supporting Structure, Pencil Drawer, and Wheels.

I needed something to mount my steel drawer too and I wanted to provide at least 2 cross braces for the top. The bottom is not going to take so much stress so I decided that 1 cross brace would be sufficient to support the lower tool bin.

Cut 3 - 27" long sections of 2"x4"
measure the width of your drawer mine turned out to be 20 inches between the screw centers. I then found the center line of my bench and measured 10 inches to either side before clamping my top supports into place. After clamping I ensured that the drawer mounting holes were lined up properly, and fastened each piece to the top frame using butt joints and screws. The bottom support was installed on the bottom center line.

For the drawer I screwed it into place using 4 - 1½“ screws aligning the drawer front to the front of the bench top.

At this time I should have added the casters to the bottom frame corners as the bench is now top side down. But my wheels were delayed due to ice someplace between here and Kentucky. My pictures are shown with the top on. ( it is much lighter with the top off)


The wheels I installed with 4 - 1½“ screws per caster I drove the screws in without pilot holes at a slight angle towards center. Unfortunately my casters did not arrive until after I purchased my screws. The screw head wound up being too small for the mounting holes. I dug around in my screw bin and found several #10 washers that I was able to use to secure the casters to the frame bottom.

After mounting and righting the table I locked each caster and gave it a good wobble. The locks held firm the table moved only a little and best of all my screws did not rip out.

Step 4: Bench Top, and Vise

Before mounting my table top I attached the vise using the cast screw locations there are 4 holes on the bottom and 2 in the inner jaw, and 1½“ screws. The vise is aligned on the right end at the corner and should only be used for light work. I believe that with a pounding the cast iron would break and the screws would rip right out of the MDF/formica top.

After the vise is secure I flipped the top right side up onto my frame and secured it with a single screw in each corner post location. I may or may not add a ½“ sheet of drywall as a sacrificial top however I dont expect too much lateral force to be applied. Well below the rating of the screws used.

Step 5: Electrical and Lighting

I was all set to wire up a 4 gang box and do a discussion about properly grounding your work. But one of my coworkers said what about these old 4 outlet Tripp-Lite Isobars. They have 4 regular 110v outlets, noise filtering, a illuminated switch, and a 15a breaker built in. Best of all in my mind it was ready to go and just needed to be bolted on using 2 1½“ screws and the cast keyways on the aluminum chassis. To protect against split soda's I mounted the outlet box under the overhang on the right side towards the back to facilitate ease of access for the lighting and

And I saved $9 as the components went back to the hardware store.

I assembled the lamps according to the directions included with them and mounted the swivels along the back edge of my table top using the 1½“ screws. Cable management is achieved by wrapping the extra cord around the power distribution box.

I wanted the ability to easily move the lamps around, say to use the magnifier on the vise, or to even remove both lamps for over sized objects like a car hood. This mounting also provides the ability to reverse the lamps to shine while working under the hood of a car.

The heavy duty extension cord is for those times when it is away from the wall.

Step 6: Modifying Server Rails to Function As a Drawer Slide.

Ok now that I have my bench top built, the vise installed, and it well lit. It is time to modify some server rails and build a sliding bin for my tool boxes.

I had originally planned on making 2 sliding bins however with scope creep and determining that one would be better suited to the space available I made one big one. But first I needed to make the rails work with my bench.

Server rail kits are awesome, you get long easily adjustable ball bearing slides, that are designed to hold a great deal of weight. However a workbench is not a server rack so I had to do some drilling and grinding to get rid of the unnecessary bits.

I began with removing the rear mounting pegs on each "ear" of the rail. Then I proceeded to drill out the rivets that held little spring loaded retaining clips. To prevent my drill from eating through my bit I dipped the drill bit in a bit of used motor oil, then drilled for about 15 seconds, dipped again in oil and kept this up until the rivets were drilled out enough to pull them through their holes.

After the spring parts were gone I was able to grind the mounting tabs for the clips using a Dremel Multi tool with a cutoff wheel.

Once again I stress safety glasses wear them love them keep your ocular balls safe and sound. Think of safety glasses as the cup of carpentry. You don't play baseball without a protective cup, don't play Norm Abrams without some spectacles for your head testicles.

Step 7: Tool Bin and Fin

The tool bin will use the rails that were prepped in the previous step. however if you don't have a set or dont need a set put a shelf down in place of this bin and call it a day.

But everything else has been overkill why not this too. The sides and back are 1" by 10" cut from a single 10' board but Unfortunately I bought when I thought I was doing 2x2 bins and there was not nearly enough board length. In my contemplation I thought what about using a narrower board for the front and taper the sides at a 45 degree angle this will provide a bevel similar to the pencil drawer. So I got to cutting.

The 10" board resulted in 2 28" pieces for the side with a 38" board for the back and I cut a 38" long piece of 1x6 for the front panel. After marking the sides for a 45 degree cut I then glued and secured the front to the sides using 1½“ screws. The back was attached in the same manner.

For the bottom I pulled a remnant piece of ¾" OSB board from my utility room where it once performed as a shelf. Then I trued it up to ensure that it was a maximum of 30" deep and 38 inches wide and square. This was easily achieved using a straight 1x6 as a rip fence clamped to the OSB. The resulting bottom was mounted using Glue and 1½“ screws.

The drawer end of the rail kit is screwed to the bottom of the bin using the same 1½“ screws the rest of this step requires. The key with rail kits is that they must remain parallel to each other to prevent binding. This is achieved by fastening one side then measuring and mounting the other side insuring that the width is even along the entire length.
I then slid the rails into the closed position flipped the bin and centered it on the bottom frame of the bench / cart. 8 more 1½“ screws and that is it the rolling workbench / service cart is done. Sit back enjoy your handy work and mount up some pegboard.... THE PEGBOARD!?!?!?!

*Edit* I seemed to have overlooked one important part that a comment brought up. If the drawer were to be fully extended it could tip the cart. To combat this I have driven a screw into the server rails so that they only extend to the first locking section. The result is a drawer that can extend half way. So the items in the back are reachable without moving the stuff in the front.

Step 8: The Pegboard

I almost forgot. I need to hang the pegboard. If you remember from my first pictures my garage is poured concrete, when it was built the builder never ground the tabs off the walls. This provided a great attachment point for the frame.

I wanted to use a whole sheet of pegboard with out any seams this made it very easy to make a frame I cut 3 - 45" long sections of 2"x4" for the verticals of the frame and used 2- 8' sections for the horizontals. Assembly is done with 2¾" screws and butt joints. The assembly is bolted to the wall, and the board is screwed to the frame with 1½“ screws every 2 feet or so. Yes the off center board looks goofy with out the board but with the sheet installed you can't tell.

And I really didn't want to go buy a masonry bit and start hammer drilling into the garage wall. The screws are ok but I may at some point in the future replace them with bolts.

Love this:

Once again I stress safety glasses wear them love them keep your ocular balls safe and sound. Think of safety glasses as the cup of carpentry. You don't play baseball without a protective cup, don't play Norm Abrams without some spectacles for your head testicles

Not sure if "ocular balls" or "head testicles" is my favorite... :)

I agree with the safety glasses. I keep several comfortable pairs around and always wear them when it is project time.

However, what I usually see left out of safety equipment recommendations is hearing protection. You are also only issued two ears, and once your hearing is damaged it does not come back. I have lost some of my hearing over the years and have gotten in the habit of putting in disposable earplugs when I put on my safety glasses.

+1 on this. I buy the foam ear plugs from the big box store in big bags. I have an old jelly jar (tall skinny one) that I keep them in. I took the lid to the jar and nailed it to the underside of a small book shelf on my pegboard. Then, I just fill the jar and screw it into the lid. Now, they're always hanging right in front of me on the peg board. Out of the way, but always accessible.

I forgot that one. Absolutely hearing protection It slipped my mind due to my my hearing being already screwed up due to years of noise exposure due to a mix of military machine shops and firefighting. The tinnitus sucks kids and having to read lips is a hassle. Fzumrk I am going to pin your comment to the top as it is such a great reminder.

So out of curiosity. When you pull the fully loaded tray out from underneath does the bench fall forward?

Sorry I didnt see this question. I the wood screws work as stops that only let the drawer come out 1/2 way... and that was not planned.

I put a screw in the rail so that they would only come out to the first locking point or half way.

Great project. I am working on something similar right now, too. Hope to share in a few weeks!

Cool beans, cant wait to see your project. I'm digging the comical kitchen folding knife of yours.
