Several years ago, I started making an outdoor workbench. I was a bit ambitious and started making it pretty big. I had put the frame together and stained it; the only missing part was adding the top and the shelf tops. As I have been known to do, I never actually finished it, and I would just put a large piece of plywood on top of it and use that as the workbench top. The rest of the frame remained skeletal.

I started making that outdoor workbench when I lived in a house with my brother. The house with a mulberry tree that I used to make some wood stands and a lazy Susan. When we moved out of that house, I listened to the hoarding nature in me, and I held onto the half-finished workbench frame instead of getting rid of it. It was too big to fit through any doors, so it went into my new garage. Being used in the same way it was previously used.

Being so large and bulky, it took up a lot of space and was tough to move. I had finally had enough with it and decided that instead of finishing it, I would make two smaller workbenches that, when combined, would be about the same size. When thinking of the design for my new workbenches, I knew I wanted to be able to move and arrange them around each other. I wanted some ample shelf storage and some small shelf storage. I was also determined to put them on wheels. I would put everything on wheels if I could. Those were my primary goals.

 

I also got the idea that I wanted to try and make it without using nails or screws. From this experience, I would say use nails and screws. I would have finished this project so much faster if I had. If you have time and want to practice with special joinery, then no need for nails and screws. I wasn’t in a rush, so I decided to try it out.

 

When I moved into the new house and lugged some of my unfinished projects along with me, I learned the drawback of making items too large. They couldn’t fit through doors or gates and had to be lifted and placed in awkward positions. They took up valuable stacking space when loading a U-Haul. For my new benches, I decided to make each wide enough to fit through most doors in my house. This way, if needed, I can throw a table cloth over them and use them as tables. This gave them a width of 30 inches. I decided to make them each 8 feet long for no other reason than that is the longest lumber I could stuff into my little Toyota Corolla, and I’d save myself a few cuts. I was already comfortable with the height of my current workbench and wanted these to be about the same height. Considering an additional 6 inches provided by the casters (wheels), I would make the frame 24 inches high. I decided to use regular price stud lumber for the frames and MDF for the top and shelves.

 

 I left one-half of the space under the workbench top completely open so that there was only the workbench top and the very bottom. This left plenty of storage space for large items such as a router table and an air compressor. I put a shelf about halfway in between the other half of the area under the workbench top. These smaller shelves would be for the smaller handheld Items I would repeatedly use for the duration of a project. I would have casters on the bottom so the table would be slightly lifted for some toe space underneath. Never forget the toe space for furniture you will be right up against.

 

Because I had nothing better to do, I decided to make the workbench frame without any nails or screws. I thought up some special joinery cuts to put them together. I had also wanted to start using epoxy resin and decided I could practice with this. I figured my special cuts made with a jigsaw and drill would not be perfect. I would fill in any space with resin to help prevent any wobble that may come up.

 

For the 2×4, I cut notches out of each end as well as in the middle. When making angled cuts like this, I like to drill a big pilot hole into the wood at the angles of the cuts. I make sure it is large enough for the jigsaw blade to fit into. This gives me a starting point deeper into the wood to make the cutting easier. The notches were placed so that when the ends of the 2x4s were matched up at a 90-degree angle they would fit in place. Those could then be fitted into large prong-like notches I cut out of the ends of the 4x4s. I used a similar tactic as before, where I drilled pilot holes and made my cuts with a jigsaw. I also cut holes out of the center of the 4x4s so part of the shelving frame could be easily placed in them.

After cutting out the notches, I was happy to find that they all fit together. Assembling the workbenches was as simple as putting really large puzzle pieces together. I broke some pieces here in there, but the overall integrity of the workbench frame remained intact. As I like to do with most things I make, I did my weight test. Each table was strong enough to hold my weight standing on them, and that is usually good enough for me.

Before sealing the joints with resin, I cut the shelves and tabletops out of the MDF boards. Since I did not use nails or screws, I could disassemble the table, add the shelving, and then reassemble it back up around the shelves. As the shelves would be stuck in a place, I did not bother securing them to the frame.

After the shelves were added, I wrapped the joints and filled them with resin. There was a lot of wobble in the resin-less assembled table, but the wobble disappeared once I added the resin. The table still seemed sturdy enough and still passed the bodyweight test.

I flipped the table over and added swivel casters to each of the 4 corners and in the middle. Having wheels on things is excellent; having swivel wheels is fantastic! It would make moving these 8ft x 2.5 ft workbenches much much more manageable. Once the swivel casters were added, I flipped the table back over. I was tired of working on it and ready to move on to other projects, so I secured the workbench top to the frame with some 18 gauge brad nails.

With my workbench done, I had a bunch of extra storage for all my hoarded scrap wood. Even better, I had so much workbench top space now! And best of all, they had wheels!!! I could put them end to end to make one long table or side to side, so they were larger than my original unfinished workbench. I could also use them separately as individual benches. I’m excited to use the new benches, though I already seemed to have used up all that new workbench top space.
