I find it easier this way.

When we're talking tenths, I'll avoid the Noga sag.

What do you propose? Im not worried about the sag when my indicator stays in the same spot and i dont turn it upside down. If you have something better than noga im all ears. In all my years in shops and industry with unlimited budget the noga is the one that gets used

 

[LVLAaron]

When I indicate barrels I usually rotate the barrel and leave the Noga stuck to the crossslide. Unless it’s a 5R. In that case I spin the whole lathe around the barrel.

Post #18. I've got Noga's too but I prefer short and rigid. Just easier for me to keep indicator in alignment with centerline of barrel. Indicator snaps between grooves, seems less mushy than when using Noga articulating arm.

I joke but I do like that setup. No needing to wipe the crossslide off... indicator always on center... I might play with it.

The best way I’ve come up with to hold an indicator. I always hated using a magnetic base and getting everything lined up.

A $28 Noga adjustable indicator Mount that threads into a piece of .22 cal barrel blank.

Best tool I’ve made

I have a $15 Noga knockoff that works fine. Solid as a rock.

Yep I run it off the tool post and now indicate at 9 oclock. That way you can set it up as an additional tool number on the DRO and move it in to exact X Y without crashing and know where you are in the throat or camber at any time. Learning to adjust at 9 instead of 12 was easier than expected and it gives you better access to the opposite bolt as needed.

Who's going to be polite and tell Jim, his Interapid needs service?

 

[LVLAaron]

I saw that and posted a reply on his FB page... Something didn't seem right about it so I did the same test and shared it with him.

 

[ridgeway]

I wouldn't necessarily say it needs service. I think he is proving there is a cosine error happening. Does he know? I come across many that been in machining for years and have no clue what cosine error is. I very rarely use my indicator to measure with. I indicate and move accordingly till it reads zero.

 

[xr650rRider]

Not sure it's what's wrong with his but don't ever adjust those screws on bottom of indicator. You can adjust the top pivot but that's it.

Sensitivity and cosine error are 2 different things. He's close to 12 degrees that Interapid should be.

Hmmm. At 38 or so in, you do see a little movement.

 

[LVLAaron]

His interapid definitely needs a refresh. He's a both-ends-dialer, so the tenths indicator is best for him anyway.

and a steady-rest before that. Set lots of records and won lots of trophies. Makes you wonder if any of the differing methods really matter on paper.

Yeah. I think about that a lot.

 

[Alex Wheeler]

His stuff has set lots of records because he understands the whole rifle. The best chamber isnt going to do anything when theres other problems with the build.

Okay…after using it the first time…still like it and it’s nice but why in the world would they have designed it to work counterclockwise?

I had to really pay very close attention that I wasn’t moving the jaws backwards because the indicator is backwards.

Still scratching my head on the design but it’s a nice indicator and I like everything else about it.
