Title: Sharing a little trick I discovered.
Post by: websterz on September 03, 2010, 07:49:05 PM
Not saying I invented it, just that it came to me in a forehead slap moment.  :doh:

Centering up round stock, or finished round parts in your mill vise, can be a pain in the butt. I figured out that before I part something off from the lathe prior to milling that if I turn and part off a little extra stub the same diameter I can chuck it up in the mill with the part in the vise and center up dead nuts every time. Just a bit of gentle pressure on the quill as you maneuver the table and when it goes in you are there. I have one part that I make several dozen of on a regular basis so I just made up one of these centering nibs and keep it with the collets. Works like a charm!

Hey...here are the pics.  Guess I kinda' forgot. :doh:

Here I have a 9/16" diameter piece of stock in the vise that needs a slot milled along its' length. I need to center the spindle for proper slot location. Rather than get out the edge finder and mess about dividing, subtracting, and all that nonsense I use my cheater. The stock in the spindle is a couple of thousandths smaller than the stock in the vise.

With the vise tightened up securely I move the table out until I can lower the spindle mounted rod between the vise jaws. Now the spindle is perfectly centered, no fuss no muss. You can do this in seconds, without a calculator or edge finder, in the dark even.

Websterz,

I use a similar trick using exact fitting transfer punches to pick up previously drilled holes in parts.

I suppose if you can afford sets of drill blanks, you could use those as well.

I'm usually at most, about 0.001" out, which for me is generally plenty close enough.
