How to build a portable miter saw table with extendable wings and shop vac shelf. DIY table top for a miter saw.
Since moving into our home we’ve done a lot of home improvement projects. Slowly you add to the collection of tool or make due with what you have.
But after making due for too long it was finally time to purchase a miter saw. Something we had been eyeing at the store for quite some time.
The problem we ran into, however, was that it wouldn’t fit on the workbench once we brought it home. Oh well, guess we’ll have to make something.
This is our own personal experience. Be sure to measure properly for your own miter saw and shop vac storage. Always seek professional guidance. Always follow your manual and practice tool safety.

Last year we built garage shelving and workbench combo and even though it’s 8 feet long, it’s not built for a miter saw. Since we still pull our car into the garage, we were going to need to make the best use out of a small space. A rolling miter saw table with collapsible wings that allowed for a shop vac to be stored underneath.
MITER SAW TABLE DIY WITH SHOP VAC SHELF
Tools
- Miter saw
- Circular saw or table saw
- Drill
- Impact driver
- Speed square
- Tape measure
- Safety glasses
Materials
- 4- 3 inch caster wheels with locks
- 4- folding shelf brackets 12 inches
- 6- 2×4’s
- 3-2×4 plywood
- Screws 1 ¼” (plywood table top)
- Screws 2 ½” (2×4 box frames)
- Washers (for the caster wheels)
TABLE TOP, BOTTOM, AND EXTENDABLE WINGS – MEASUREMENTS
Our top table measures 30″x24″
The bottom shop vac shelf measures 27″x24″ (to account for the attached legs)
Each wing is 30″x24″
Measure and cut your boards. Be sure to use your 2″x4″‘s wisely or you will come up short.
2″x4″ Frame Measurements
Pre drill holes to avoid splitting.
- 4-30 inch for the wings
- 8-21 inch for the wings, table top and bottom shelf, sides
- 4-27 inch for the front and back of the table top and shop vac shelf
- 4-35 inch for the table/shop vac legs. (measure for your own personal shop vac height)
Plywood Measurements
We bought 3-2’x4′ plywood boards. Using the leftovers to make the bottom shop vac shelf-saving us a bit of money.
Miter saw table plywood- 30″x24″ (measure, cut and secure AFTER attaching the table legs.)
Extendable wings- 2- 30″x24″
Use the leftovers to build your bottom shop vac shelf.
PORTABLE MITER SAW TABLE WHEELS
Mark and secure the caster wheels to the bottom shelf 2″x4″s with screws and washers. (Again, we pre drill our holes to avoid splitting)
BUILD THE FRAME AND SECURING THE TABLE TOP
Flip the boxes on the side and attach all four table legs to the top and bottom shelf.
Now that the center is complete, lock the wheels, measure and cut the plywood table top.
Secure.
HOW TO ATTACH THE EXTENDABLE WINGS
The wings are going to be raised on either side to be level with the deck of the miter saw. Be sure to do the math and measure a couple of times before attaching the shelf brackets.
The deck of our miter saw is 3 and 9/16 inches (just over of 3 ½) off the table top. The wings are 4 inches thick, which means we needed to drop our bracket down 7/16 (just shy of ½) of an inch for it to be level with the miter saw deck.
Your measurements will be different than ours. The miter saw and thickness of plywood you choose will play a part in deciding where your bracket needs to go.
Measure from the bottom of the miter saw to the miter saw deck. Measure the thickness of your extendable wings. Subtract the difference and attach the brackets there. Good enough is not good enough, be precise.
Mark where the shelf brackets will attach on both sides before attaching the brackets.
Flip the table upright and secure the miter saw.
MITER SAW TABLE DIY WITH EXTENDABLE WINGS AND SHOP VAC SHELF
This miter saw table is fairly tall sitting at 39 inches where the saw sits. For a tall person and a tall shop vac, everything is comfortable. But keep that in mind when making your own miter saw table. The plywood and caster wheels each add to the overall height of workbench.
HOW MUCH DID THIS PROJECT COST
It depends on how much you have on hand. We purchased the 2x4s, plywood, caster wheels and brackets making our total a little over $200. Prices may very in your area. We found and purchased everything local besides the brackets. We purchased those from amazon.

Where did you find the brackets for the wings?
Thanks

I believe at the time we purchased our brackets at Home Depot. But doing a quick search online you might get a better deal on Amazon or in person at the location home improvement store. Just be sure they are rated for the weight you need.
Hi could you tell me the thickness of the plywood that you used thank you Leslie
Hi Leslie, We used 3/4 inch thick plywood for the table top our miter saw sits on, and 1/2 inch plywood for the extendable wings and bottom shelf.
Thank You for the ideas, plans, etc. Most importantly, Thank You for your Service :)
It’s nice to see someone sharing diy plans & photos instead of asking people to pay for them
Thanks very much
