I previously made this part using 1/4-20 screws and I thought the nut holes might be a little too big. So I made this one also to take #10-32 screws and matching locknut. I have not yet tried this. If you have any suggestions please let me know.
Again, this is for size #10-32 steel screws and Nylock nut.
THIS IS NOT A TESTED, WORKING PART. I will update this when I have a final draft.
Let me know what you think.
EDIT 3/21/2018: I added my signature to the part. That is all.
EDIT 3/26/2018: I tightened up the nut slot by .005" to make it a little more snug.
