Ace 101 spine tester: odd problem

[slowbowjoe]

So I've had one of these for about a year, made up maybe 5 dozen sets of shafts, all from reliable sponsors here. With all sets, my Ace
consistently reads about 5 ponds lighter than the actual spine. Had the shafts hand spined and marked from the suppliers on this last batch, and same results.
Any ideas as to what I may be doing wrong, and how to correct it?

I'm not sure which model you have. I had the 203 Spine Master and had a similar issue.
I emailed Ace to ask if there was any way to adjust the tool and received a rant about how it was calibrated before it left their doors and there was obviously something else wrong, it certainly wasn't the Ace tool.
I wrote to the shaft supplier. They gave a little laugh and said that's not the first time they've heard of the same issue with the same tool.
I fianlly sold the Ace and got a used Adams. I'm much happier with the Adams. I'd have been fine with the Ace if they'd helped me instead of getting up on a soapbox.

Real easy to check if you got some XX75 aluminums.

[slowbowjoe]

Don't have any aluminum (or carbon, for that matter) to check against.
Guy, I had a little better experience talking to Ace, as the gentleman was patient and helpful offering suggestions... but I still don't get a reading that matches the actual spine.
Anyone other feedback out there?

I had the same model a couple of years ago, same issue.  I even kept it side by side for testing once I got a Spine-O-Matic and it was consistently 4# light.

Thanks Green, that's a pretty good confirmation - within a pound of what I think I'm off by. Well at least now I know it's probably not all operator error. No way I can afford a replacement right now, and I do find it works very well as a spin tester/straightening aid-guess I'll just have to trust it's at least consistent being 4 or 5 pounds light.

[Green]

If you know it's consistently off, then you can use it fairly accurately.

Does the Ace spine master have the same problem?

I have a 203 and it was a little off compared to what my aluminum shafts should have spined. I just bent the pointer the slightest amount to zero it out. Took about 10 secs and has worked fine since.
