[Rockchuck]

What is the model # of long reach intrepid indicator that you guys use for indicating a rifle barrel?

Thanks

I got mine on a smoking Enco deal with a 30% off coupon! I miss Enco...

Just curious is there other good options? Or is the intrepid the holy gail??

 

[LVLAaron]

mitutoyo 513-504 is in common use. Can't comment if one is better than the other.

The Interapid is the best you can get. However, there are other, cheaper options but you get what you pay for.

The 513-504 is nice because it fits in most chambers. I'll have the Interapid tomorrow... I'll offset a test bar and line them all up and see how they respond.

Yes I would like to see that done.

The Mity with a 1.5" stylus might be the best of both worlds. They're just fatiguing to read because the dial is small.

I'll be able to do it with the 2.75" point.

Currently trying to get long island indicator to cancel my order and just send me the 5.5 tip.

I can't imagine laying down a 5.5" stylus in a 6mm bore and trying to indicate with it.

Jus da tip

I’ve also been direct reading the throat area after pre boring, with a 513-504T, using a grizzly rod & bushings beforehand for the initial dial-in.

I’ve not used a long tip indicator. I picture the long tip having some tendency to ride up the bore’s ID as it’s rotated, causing some possible measurement error. Do you notice the needle settle to the correct reading as you rotate a tiny amount back and forth? Or is the tip rigid enough that this isn’t a thing? The 513-504’s tip is very short. If it deflects sideways at all, I can’t detect it.

I've done it already, as I'm sure have others. I'm curious if Aaron's results are the same.

Indicator sensitivity test.

The subject of indicators came up in a few other threads and I've seen phrases like "zero runout" and "no movement is zero" used. I've done this test before, but I wanted to repeat it to make sure I wasn't talking out of my A**. These indicators are all equipped with the factory length...

I think you'll find it's just as sensitive as the Interapid, but the dial is so small it's very hard to see the needle move.

Think 33xc and 416 sized chambers.

Still with 30+cal and 5.5" stylus and a shallow angle, I can't imagine it's reliable. I dunno...I'm a skeptic on it. Buy hey, I've been wrong before...as long as it works for you.

Its a good tool to have in your bag of tricks. Its built like a fine watch

The 5.5" is only when you have to use it. It's a pain and not as sensitive.

I wish they made a 3.2" instead of the 5.5.......
