Are there two holes in the end--one centered and another (probably smaller) one offset towards the slot that's milled on the outside?

I think it is a manual wire wrap tool. Here's a picture of what looks like the same thing. (I grabbed the picture from Amazon's web site.)

Is there an easy way to search for stuff on this blog?

Use Google. If you add "site:chaski.org" (without the quotes) to your search, Google will limit the search to this forum. For example:

Doing that makes absolutely no sense. (to me!) Doing what? I'm getting confused! Setting up the rotary table/part with it horizontal and then flip it to vertical to do the work... I agree. That's why I tried to suggest a way to center the part on the rotary table with the rotary table oriented vert...

The jaws bind up as they reach the last 1/2" of travel, before they touch each other, closing down. Thanks for that! I was thinking maybe if you were a complete newbie, you might not understand how the jaws must be installed in 1-2-3 order when you're assembling the chuck. But that's obviously...

This seems to me like a more direct way to get where you need to be than aligning both the rotary table and the disk to the spindle. The method that I described allows you to accurately zero your dials (or DRO) at the center of rotation if other features need to be accurately placed. Good point! Fr...

Would the following steps work? 1. Mount the rotary table vertically as you need it to do the work. 2. Bolt the disk to the rotary table so that it's snug but can still be moved around. 3. Set up a dial test indicator so that it rides against the edge of the disk. 4. Adjust (tap, tap, tap) the posit...

Also helps if you're trying to install countersunk rivets exactly exactly exactly flush with the surface.

Add me to the "OMG, that's awesome" crowd.
