DIY Pneumatic Saw Clamp

Many years ago my father was working on a new shop behind his house. The insides were left for us to finish. We needed to build work benches, shelves and racks. To save money, he bought the longer 2×4 sized lumber and we’d cut it to whatever size was needed. This worked out great but the extra-long boards were unruly and a challenge to cut by one person because of the length. We didn’t have a nice chop saw setup that is so common now with the nice outriggers and side supports. We basically hade a saw with an old Black and Decker work bench. The kind with the clamp built into the table top.

I started using the manual clamp that came with the saw but its range was pretty limited and it was better suited for thinner material than a 2×4. I remembered a pneumatic cylinder that I had grabbed out of a junk pile and thought that I might be able to make an automatic clamp with it. I found a piece of steel to mount the pneumatic cylinder to and then used a section of rod for the post. The rod had to be turned down by a friend on a lathe so it would fit in the clamp mount on the saw.

When I first used the pneumatic clamp on the saw I was amazed at how much force it had. I was able to place a 14 foot board under it and it would lift it and keep it perfectly clamped on the saw. When you’re trying to cut off 2 feet of a 14 foot board, that’s a big deal.

It was so useful for my dad and me that I wanted to revisit the project and share it on my website Neo7CNC.com and the Neo7CNC YouTube channel. I started documenting my very first DIY CNC machine build years ago and posted the videos on YouTube. With each new CNC machine or contraption I built, interest on the channel kept growing. I’ve continued to share my machines, experiences and information ever since. I really enjoy inspiring others to make things (CNC or not) and the interaction with viewers and sharing of knowledge is a huge bonus.

Since randomly finding a pneumatic cylinder doesn’t translate very well to my viewers, I wanted to find a source for most, if not all of the needed components for this build. AutomationDirect.com was my first choice. With a great selection, good prices and fast shipping, it was a no brainer. I’ve used them many times over the years. Not just for pneumatic parts but also for buttons, enclosures, sensors and much more. I was able to find just about everything from them. The only other items needed can be found at most local hardware stores.
