DIY Smith Machine
This project I could not find online other than one person who welds. I am not about to buy welding equipment to try this with. If it came to spending the money to purchase welding equipment I would rather just buy a smith machine and follow the assembly instructions. If however, you have welding gear and knowledge to use it you will find a video on YouTube about how to do it. For the rest of you, here is my version built out of wood.
This project has taken on many hours of trial and error and is sadly still somewhat of a work in progress. I believe I know what went wrong and how to fix it. My error was in using 2×4’s not 4×4’s or doubling 2×4’s together to make the frame stronger. This however, is actually not my biggest flaw. My biggest flaw was in failing to line up the bars exactly straight and in not using wider T-Connectors to slide over the bars. I did find a great lubricant (after trying many) to make it slide much better. Be sure to head all safety warnings when using this lubricant (“Liquid Wrench”) found at Lowe’s.
My other mistake which seemed logical was to save money and line this up so the weight bar will use the adjustable safety bars that are part of my workout cage rather then making them separate. This was a failure because as you will see in the pics below it makes the bar lean back towards the safety bars and is much harder to grip, balance and slide up and down to use. I used 1/2″ hollow steel pipes with 3/4″ T-Connectors which I guess should have been 1″ T – Connectors to glide better with.
As of today 1/21/21 I have not gone back to fix this project. As of now the structure I built is a failure as a smith machine, but a success for creating a structure for multiple working pulley systems to be connected to which you will learn about on other pages on this website. I will update this page once corrected (most likely summer 2021).
For safety my entire structure that I carefully built by myself (using ropes to hold parts in place while attaching other parts) was a major feat. Be sure to have someone with you when attempting to build something like this. My Smith Machine is secured to the back wall of my detached garage and also both the left and right side of it as well. The wood sits on top of bricks since sadly this tin roof leaks somewhat and requires me to cover the weight bench with a tarp when not in use. The bricks keep the wood from sitting in a puddle of potential rain water.

A closeup view of the bar and where it sits. Originally I had designed the weights to hang from the bottom of the weight bar. Later I changed it to be on the ends of the bar.
Another view showing the frame for the smith machine and how it is secured. Notice it also sits on top of the workout cage.
This is how originally I had weight plates planned to be lifted up and down using this Smith Machine.
Later I added additional 2×4’s (both sides of the poles to slide the weight bar up and down on) for added strength.
