Adjustable Height Modular Workbench for Table Saw
OK. I'm calling this project done for posting purposes. Using the concept of my interlocking modular workbenches that are 2X4 feet, I set out to make a new bench for my table saw that I bought at Menards this winter.
The basic concept is that half the bench, 2X2 feet, will be set at the height of all my other modular workbenches made out of pallet wood. Here is a picture of that first half...

Notice the 2 holes drilled into that top 2X4 on top. That allows me to run a 1/2-inch, 4-inch long, bolt through my workbenches and tie them together. That's the interlocking part.
On the right side of the bench, I made some adjustable height legs, cutting out a groove in the 2X4's and running a bolt through the 2X4's. Those legs can be adjusted in any number of heights and tightening down the bolt will lock it in place. Here is a picture of the right side of the table at full height...

Here is a side view of that showing that at maximum height, the right-side tabletop is about 3 inches taller than the standard work top of the left side. That might come in handy as an outfeed table for some projects...

I suspect I will probably use the workbench at either flush on top, or down for my table saw. However, while I was making the right-side adjustable height legs, I came up with the idea to add a rail type system where I can run the bolts up in the groove for any number of adjustable heights. Here is a picture of the rail system, along with the top 2X4 with hole drilled in it for a flush top position...

Since this workbench was specifically made for my new table saw, the default height of my adjustable legs was cut to make the right-side table flush with the top of the table saw. Here is a picture of the legs tucked up and stored in their "default" position for use with my table saw...

And here is the final picture with the new table saw mounted on the right-side of the workbench...

I made it so that the right-side top of my table saw is 1/8-inch higher than the left-side top of the workbench. That allows any wood I cut on the saw to feed out on to the left-side without catching, yet the 1/8-inch drop in height should not have any negative affects on my cuts. If the drop was significant, the wood could potentially bind in the saw blade and that needed to be avoided.

There is some final touch up work that needs to be done later. That was the first time I ever cut grooves into 2X4's like that. Out of the 8 leg pieces I cut a groove, I think I tried 8 different methods. At the end, I got pretty good. But the first grooves I cut need some finesse work done with a wood rasp or file to smooth out the inside grooves. I don't have a
wood rasp kit, so I'll have to pick one up at Harbor Freight.

Well, the workbench is in working condition right now, so I'm not in a great hurry to get those wood rasps for that final touch up. The rasps are only $4.99 for the kit, but I think I will wait until they go on sale or maybe I have a 20% or 30% discount coupon to use.

That's a lot of open space under the workbench, especially on the left-side. I think future upgrades may include pull out drawers or adjustable height shelving. I did that on one of my other modular workbenches and it holds all kinds of parts storage boxes. I cleaned up my shop while at the same time getting things more organized and easier to pull out and use.

I thought it would be a one-day project, but it ended up taking almost 2 weeks, on and off, mostly off, due to life problems and my miter saw malfunction warranty issue. Like most things, now than I know how to make that type of workbench, I could build a second one in half a day of working. I have a steep learning curve in woodworking.
