I'm a big fan of marking gauges ... we go way back. Rulers, squares, compasses of several varieties ... I got 'em. I have a love affair with combination squares especially .. I have several. 18", 12", 6" ... heck I have 3 of the 6" model alone. I have found that 3 just isn't enough for me. It never fails ... as soon as I change the setting on the gauge, I need that measurement again.
In the past I made a marking gauge for 3/4" stock which is always set for 3/4" and 1" and it was/is great. This time I want gauges not limited by material thickness. I want to have a set of gauges that I can just grab and never have to adjust. I also want them to be free.
Of course I have poplar scraps ... I also have 1/4" acrylic cutoffs, machines screws, and superglue.
Cutting the Poplar

I'm going 8" for overall length. With that you can easily mark a 1" x 6" or 1" x 8" in one shot. You could make that repetitive cut at the miter saw with a stop, or on the table saw with a crosscut sled. Another method I use is to add material behind the stock to make it more stable and reduce chances of kickback.
I ripped the 8" stock into 1" widths
Cutting the Acrylic

If you can swing it financially and find yourself cutting acrylic regularly, get a dedicated acrylic blade. Mine is made by Freud and it cuts like butter (buttah here in MA).
There is some math/thinking involved with these measurements. The poplar stock is 3/4" thick so we have to add that to the desired gauge measurement. I also prefer to cut long so I can sneak up on the cut to fine tune to finished product.
Example
I want a 1" marking gauge
3/4" stock + 1" marking = 1 3/4"
Since I want extra, I'm going to cut this at 1 7/8"
I label each piece as I cut it to maintain some order. The critical factor is "your stock" + "your desired gauge."
Initial Assembly

I'm using superglue for initial assembly. That will hold long enough for me to dial in the gauges on the table saw before adding screws.
I just use a scrap piece of wood as an alignment stop, apply three spots of glue, slam the parts together and clamp them for about a minute so the glue can set.
Trim to Size

Next step is to trim each gauge to its final depth. Just keep in mind the [stock + gauge] measurement and you'll be fine.
Sorry about the upside down measurements ... I could really use a left handed tape.
It's off camera, but I actually used a gripper when making these cuts. That held the poplar and acrylic against the fence, as well as to the table.
Drill for Screws

![16 Drilled.JPG](/proxy/?url=https://content.instructables.com/F4K/SXPQ/IBL68NUS/F4KSXPQIBL68NUS.jpg&filename=16 Drilled.JPG)
I'm adding 5 screws to each gauge .. because I want to.
For my locations, I measured in 3/8" in from the long edge or rail (half of the 3/4" stock) .. then 1/2" in from each end, 2 3/8" in from each end, and 4" for the center.
I drilled the holes with a standard brad point bit on the drill press.
Apply Screws

To keep everything tight and in place, I throw on some clamps prior to driving the screws. Most of the work is done with an impact driver, but I do the last bit by hand in order to avoid stripping out the wood.
Finishing

For finish I'm going with 50/50 boiled linseed oil/mineral spirits. I might add a coat of wax in a week or two if I'm feeling frisky.
Now I'm ready to mark whatever my little heart desires. Thus far, I have 11 gauges. If I find another measurement being used repetitively, I can always make more. Otherwise, I can use a combination square.
Next step will be to make a storage rack ... I have yet to decide on that design.
