I made a spring loaded tap follower about a week ago. I finally got the chance to use it this morning, when I was making myself a couple machinist jacks.

The tap follower worked perfectly.

I used a a scrap barrel stump that was removed from a BAT .338 Lapua rifle for the machinist jacks.



I left the hole alone, except for a light chamfer, so that the old .338 Lapua lands and grooves would still be visible.



I hate throwing away good steel, and since I have a bucket of old barrel cut-off stumps, I've been making tools with them lately.

The tap follower, and the edge finder in my other thread were made stumps as well.

Like that tap follower too. I need to make one. How tight is the telescoping fit?

I aimed .0005", lubed with some redline grease. I ended up with about .0004 at one end and .0007" at the other. A little taper due to deflection I suspect, but it slides smoothly with no obvious wiggle.
