I needed two tee nuts for my Palmgren x/y table. So I found two oversized 1/2" thread nuts and milled them down.
It's tough steel but milled fine.
I reduced the width as well. Then I found that the vise I was mounting would only accept a 3/8" bolt...not a 1/2"...and I found two nuts that fit perfectly in another drawer of clamping hardware...oh well. At least if I need to use a 1/2" stud on the table I'll have nuts to fit.
