I have relatively small in-garage shop and try to keep my power tools mobile or foldable as much as possible, so upgrading my contractor-grade DeWalt table saw to a cabinet saw is a step I am not yet ready for. However, the limitations of contract saw are pretty clear, like rip capacity (though decent 32”) and limited support for the long pieces when cross cutting. I was looking for a DIY solution for DeWalt saw all over internet, and all I found were full-size cabinets with a saw dropped in. I already have permanent outfeed/assembly table, so building another cabinet seemed an overkill, so I ended up adding this removable extension that gives 40” of support to the left of the blade – in addition to 32” to the right.

No saw modifications are involved – the base pinches the tube frame with four 1/4” bolts, and the top rests on that base.
The level of the top is adjustable with the wrench, and the whole thing can be detached in a few minutes. The triangular hole in the right side of extension table provides access to the lever that releases riving knife.

I used 3/4” birch plywood for all parts. The top is stained with red cherry+golden oak mix stain (to match my fence), finished with spray lacquer and layer of wax.

Today I used it to cross-cut long 6/4 birch boards to size, using Incra miter gauge – works very well, safe and precise, no need to pull out circular or miter saw for rough cutting.

Yes you turned it into a $1000 unit. Keep a sharp blade on it and it will be great.

Hi Bobah, I have a small 14’x 18’ garage and with my copie of JayBates MiterSawStation I have to be smart about the space I have left. Like you, I don’t have the cash or the space for a full size table saw cabinet. So your table extension look’s really thought out and seems to be very functional compared to many I’ve seen on the web also. I was going to copy off of this nice extension which I found will reading the Dewalt reviews on Amazon…
Just like you, I have a small 14’x 18’ garage and with my copie of JayBates MiterSawStation I have to be smart about the space I have left. I don’t have the cash nor the space for a full size table saw cabinet. Finally, here’s my question… I’m pretty visual and I have a hard time figuring out how you actually “pinch” the base tube with the plywood base! It look’s like the table base is just wedged underneath the tubing not bolted down but leaning on it’s own weight to hold it in place! Is my assessment correct or Could you put up a couple more picture’s from underneath and around that base and maybe some detached from the Saw. A video would be awesome I you’d take the time but I’m new to LumberJocks and don’t know if this could be done. Thanks

Hi Yannick. You might be right, there is not much pinching involved. If I remember correctly, the whole base mostly lays on the frame tubing. It became super sturdy when I added vertical front and back supports and attached the top, so the base stays wedged in place.

Recently I have added two legs and stretcher to support the outer edge to eliminate slight flexing when heavy material is being cross-cut.

That’s a great addition to your saw. I have a Bosch and I could use an extension like this.
It looks better than some of my friends dinning room tables.
