Sherline Mill - DIY T - Nuts

I ordered some of those A2Z T nuts a few years ago and I really like them. The Sherline T nuts don't make any sense to me; they protrude just above the deck surface, are far to short, and are difficult to slip in with out looking closely.

It looks like A2Z went out of business but the T Nuts are still available for $5 - $6 each.

I decided to make my own.
First I had to decide on my own set of dimensions, and as with any DIY project you can be more precise. So I made my own choices regarding how loose to fit them.

I started out with the dimensions of the slots in the table, then the dimensions of the A2Z, and lastly the dimensions I wanted to target. 
I used the dimensions at the bottom of the sheet, the red are the dimensions I achieved, .

I always try to work in long strips and make an over sized "blank" or extrusion. I had to turn down the heads on three 10-32 screws so I could clamp my strip stock directly to the table.

The dimensions are good!

I divided up the strip stock into equal parts around 0.550" long, cut them with the band saw, and finished then on the 1" belt sander.
