2x4 L Shaped Work Bench Cut List / 3D Printed Accessories

### Updates: - **6/2/20** - Added instructions and 3D dimensioned images to help build this workbench yourself. If you have any questions, feel free to ask, and I'll do my best to assist! This is a 2x4 L-Shaped workbench that I designed based on some basic cheap workbench designs I saw online. The materials for this build cost around $100 USD for the 2x4's using premium full-sized 96" 2x4's from Home Depot. For the workbench top, I used a single 4'x8'x3/4" sanded plywood which cost around $40 USD. For the shelves, I used 4'x8'x3/4" sanded plywood which cost around $20 USD. To paint the 2x4's, I used Rustoleum Gloss Smoke Gray. To finish the workbench top and shelves, I applied 3 coats of Varathane Ultimate Oil-Based Polyurethane (sanded with 150 grit before applying urethane and sanding with 350-400 grit between coats). Included is an optimized cut list in PDF form created from Kurraglen Industries' great free cutlist optimizer website. ### Tools: I'm an elevator constructor/electrician by trade, no expert woodworker. With this project, I borrowed a friend's chop saw and table saw, used my Makita RT0701C 1 1/4HP router to smooth out the edges of the 1x6" backsplash I used to mount outlets and a brush plate for cleanly running wires from underneath to the work surface. ### Instructions: - More detailed instructions are coming soon. This initial post is mostly to share the 3D printed files such as the Pegboard spacer, wire management, work surface tramming mounts, etc. - The Board Tram Mount file is for mounting the work surface from underneath without having screws show from the top. This also was advantageous seeing as the top framing of my workbench became twisted and wasn't completely flat. Using 3/4" screws I screwed it from the bottom, trammed the bench top using shims and screwed it into the 2x4. This is much faster and easier than making pocket holes. - Dimensioned Images: - [Work Surface Framing](https://jimbalny.github.io/images/Bench/WorkSurfaceFraming.png) - [Top Shelf](https://jimbalny.github.io/images/Bench/TopShelf.png) - [Bench Legs](https://jimbalny.github.io/images/Bench/BenchLegs.png) - [Bench Bottom Shelf](https://jimbalny.github.io/images/Bench/BenchBottomShelf.png) - [Bench L Framing](https://jimbalny.github.io/images/Bench/BenchLFraming.png) ### Materials Required: - 2 1/2" construction screws (I prefer the T25 torx head ones, lets face it philips sucks if you ever want to take this monstrosity apart) - 1 1/4" construction screws torx head - 3/4" wood screws ### Construction Steps: **After you've finished cutting the 2x4's as listed in the cut list, it's recommended to predrill the holes and drill countersink (if you have the tool to do so) and build the frames in this order:** 1. Build Work Surface Framing 2. Build Bottom Shelf Framing 3. Screw 4 Legs to Top Work Surface (upside down) 4. Flip over and using 4x 6" cut scraps of 2x4's sit the bottom shelf on top of the 6" scraps underneath the top work surface to more easily drill and screw in the bottom shelf 5. Build Top Shelf Framing 6. Screw 4 Top Shelf 72" Legs to top shelf framing (upside down) 7. Flip the top shelf frame with legs attached on top of currently built bench, drill and screw in 8. Build Top Work Surface for L shape Part and attach legs 9. Attach the L shaped top work surface to currently built bench (may need to use scrap 2x4's screwed into bench top frame in order to have something to screw into) 10. Finish construction of bottom shelf on L part using above diagrams for reference 11. Measure for shelves and all work surfaces you want covered in plywood or preferred work surface. I used 1/4" sanded plywood for shelves and 3/4" sanded plywood for work surfaces sanded with 150 grit, finished with polyurethane sanding with 350-400 grit between coats
