1/2"-20 is also known as 1/2" NF (National Fine). I only have a 1/2"
NC tap which is 13 tuns per inch. <br>
The 20pc set from Canadian Tire doesn't have the 1/2" NF either. You
can find singles at most hardware stores for a few dollars... <br>

<div>I'm curious if anyone has any feedback on my a-axis design.

When using an A-Axis I was thinking that I could mount the
work piece in two ways. I could have a chuck at one end and
a flat plate at the other.</p>
<p style="margin: 1em 0px; padding: 0px; display: block;">
The flat plate would allow me to bolt stuff to it. I guess
if it has the right hole pattern it should be easy to make
pulleys. I could cut the bore and rough the outside using a
2.5D method. I could add the mounting holes that match the
mounting plate on the A-Axis and then finish the pulley or
gear on the A-Axis.</p>
<p style="margin: 1em 0px; padding: 0px; display: block;">I
could also mount odd sized pieces with the plate.</p>
<p style="margin: 1em 0px; padding: 0px; display: block;">I
suppose this plate could be made of 1/2″ thick aluminum? I
could drill and tap the hole to match the threaded rod that
I’m using as the main shaft of my A-Axis assembly.</p>
