This does not qualify as woodworking, so I’ve placed it here. I don’t have a lot of use for a marking gauge, so I didn’t want to splurge on a manufactured one. I decided to try making a small marking gauge that would have brass elements. I like the look of brass and I’m a cheapskate to boot. I found a plumbing fitting which I felt would work. It was a 3/4 in. x 1/2 in. male adapter MPT x barb. I cut the theads off the 3/4 end with a hack saw and then ground off the rest until I got to a flat face.

I drilled and tapped the 1/2 in end to receive a 8/32 brass lamp screw. The bar is just a 5 1/2 in. length of 3/8 in oak dowel which I had to sand down to fit the hole (about 5/16in). A brass clad screw placed in a predrilled hole in the end completes the gauge. Is the screw a little small for my fumble fingers? Yes, does the thing please my eye and function as a marking gauge? Yes.

You have proven that ‘simple’, simply works just fine.

Well done.

This was one of those little projects that ended up being more work than I thought. I had to grind away more brass than I’d hoped when I conceived the idea. Best part is that it fits nicely in my marking & measuring drawer.
