Which indicator?

[JamesnTN]

now that I have a lathe on its way. I need to know what indicators are you guys using to indicate the bore in? I'm assuming a .0005 long stem?

Interapid 312b-15 that's the long stem. I also use a 312b-3 its a short stem .0001 and I have a mitutoyo 513 pocket test

James it's also very hard to beat Noga mag bases if your looking for them also

I use intrepid, be sure to get the larger diameter face. I use the .0005" indicator, it has a .060" range and it easily gets you to the less than .0002" you're looking for when dialing in a barrel. If you're going to be doing a lot of larger calibers, you may not be able to reach the throat with the long stems. I use Gordy G.'s method of a long rod with bushing chucked in the tailstock. It works pretty well.

I like the Mitutoyo listed above. I do have an Interapid also, but not my favorite.

Check out longislandindicator.com They repair and calibrate indicators and offer some good information. On the home page scroll down to test indicators- brand comparisons

I picked up a used 0.0001 bestest on ebay. They seemed to be the best bang for the buck. Also have a couple of 0.0005 mitutoyo. No long tip indicator yet but plan to get one.

Second the Noga bases.
