Now I am wondering if this could be the cause of the inconsistencies I have found from my own tester and factory bought spine indexed arrows..... ?

Would be interesting to see from you who have removed spring to test a few arrows both way (spring in and out) if the dot has moved....
I know that with my spring out ,Jerrys arrows were on the $$$$$$$

It's far more difficult with the spring in place if the shaft wall is consistent

But, I have indexed for over 20 years so I can work with the spring in the gauge but it take a modified technique of spinning the arrow differently, a very light touch and watching the gauge for very subtle movements in a clockwise orientation

Not so consistent shafts could almost be indexed with a broken gauge 😅🤣🤣😅

Well bummer.

Removing the spring in my metric dial indicator was a piece of cake, but my standard one looks to be more difficult.

There’s a pin extending from the rod that’s tucked into a piece of “channel” plastic (top arrow), and the spring is attached to that pin and secured at the other end that appears to be held by another pin in the housing (bottom arrow).

It looks like there’s 2 screws to the left of that channel that may remove it so I could get the spring off that pin, and then I could put them and the channel back in. Or maybe I can use a pair of tweezers to slide it off. I’ll have to take the back off again.

Not sure if I should cut the bottom of the spring or just let it dangle. Has anyone seen an indicator like mine? Thanks.

I cut mine then use needle nose to carefully bend the hook on the pin

Then turn it over and with a light tap the other recessed pin falls out

Removed the plastic channel screws, lifted it out, slipped the spring off the little pin, turned it over and the pin holding the other end of the spring fell out along with the spring.

So the springs are removed from both of my dial indicators but it begs the question why they were put there in the first place? 🙃

That's an easy one. Because everything isn't checked from the top where gravity controls the probe. With the spring they can be used horizontally, from the bottom, or any angle.

They weren't made for just checking arrows.

Tension and application.

Makes sense.

Never seen one used sideways or upside down - and mine won’t now either.

I see it every Monday thru Friday.
And lately Saturdays too! Usually tension is not an issue in most machining but it does come into play on occasion.

Checked the spine location on my Tapps and Zombies from SSAS and they were right on the money, as were the Executions that I indexed myself.

It just seems without that spring the needle seems to operate a bit more smoother. I would think checking the deflection would be just as smooth too.

I like your adjustable weight, that is a new one for me. And one I will implement. 1.94# to 4# no longer a problem. What is the maximum you have used in the medicine container and what material. I have an older DIY arrow spine finder, have a new one ordered. The older one will now be able to check deflection and identify the stiff plane.
I'm thinking shot of different sizes and weights will be my go-to...
Thanks TP!

I cannot imagine why the springs would need to be removed for accurate readings for indexing if using a quality indicator. Have you all tried using tips with geomotries that may be a bit more suitable for small shafts? Some tips even have roller bearings in them these days. Also curious if a last word-style indicator may even be a better choice of indicator overall.

I don't index arrows (yet), but I use indicators almost on the daily. So just throwing some thoughts out there.

It’s a stainless steel media that I use in a rock tumbler drum to clean pistol and rifle brass for reloading - I think I have about 3# of it.

Last time I checked it was 1.94# dead nuts. I suppose using copper plated BB’s would work just as well.

Give it a try and you will see! On cheap arrows with a lot of deviation no problem, the gauge with a spring works fine but on really consistent arrows it makes it very difficult.
