Tips for measuring shafts for you resellers

classiccues said:
Thanks.. I have the standard digital US postal scale that you get at staples and a nice starett that I had when I was in engineering. But like I said in the first post, you need to develop a little touch when using them. If you over squeeze you will dent the shaft and ultimately get a bad read.

With the digital calipers, I put masking tape on the inside of the jaws to protect the shaft, closed them and reset that to 0 to account for the tape thickness. It will accurately measure out from there and won't harm the shaft.

How much would be removed from the edges with the file? Guess it wouldn't change the reading by more than a couple 1,000th's?

If I'm not mistaken a lot of digital calipers let you zero the scale. So zero it after you file and you're accurate again :cool:

Sure! Hadn't thought of that. No experience with that tool. Thanks... now it sounds like a good idea. ;)

I ordered the $3.95 6" calipers from Amazon (Grizzly), but here is the card you referred to, and it is on sale for $.95. It increments in .5mm sizes, and anyone who sells, buys, or trades cues should carry one of these or calipers.

Love your little buddy there Scott. Mine is a 20 lb Benji mix. Beautiful creatures dogs... so much heart. (sorry to hijack the thread)

Just to be safe.:D

Really, though. Good advice, Joe.

You either omitted or fat fingered a number. I tried your number and didn't get the correct known answer.:confused:

Is the last number rounded off? If not you should have ended with... That may be where the mistake occurs.:D

I seen that pi has been carried out to enough places where it could fill up a decent size phone book. Glad that our tax dollars are being well spent on research.
 
When was the last time someone tried to sell you a 13.0 shaft and advertised it as 12.75? (that was a rhetorical question).
 
This is excellent information. Anyone who is selling a quality cue should be able to supply accurate, detailed specs, including shaft diameters, weights and butt weight. I use a digital caliper and a tanita digital scale and know my specs are correct whenever I sell a cue.

Thanks and if I prevent one deal from ending up like the one I am going through, its all for the good.

Great post.

One of the ways I measure a shaft is to use calipers on the ferrule, then go up the shaft at least 10 inches to see if there are any measurements less than the ferrule measurement where it meets the shaft wood. Most of the time the wood area if larger, but once in a while I find a shaft that someone has sanded and it is tapered like an hour glass. I always try and list the smallest dimension measured so no one can cry FOUL. It has saved me a lot of headaches. It's hard to beat honesty.

Thanks.

Jim, it should not change the reading at all Its just the square edge, not the flat part. As mentioned you can re-zero. If you would rather not file just use tape as mentioned. You still have to be careful so its your choice.

Pi is a transcendental number; the exact value can never be computed. I believe the most recent calculation yields about 200 billion digits.:eek:

There are a lot worse subjects to research... Math, aside from logic, is the only 'truth' in life. ;)
