Scribing vs. Yellow pencil
« on: September 23, 2015, 02:38:43 PM »
Why do certain pro shops scribe the ball and leave permanent marks instead of just using yellow pencil. Just had an internet company drill a couple balls for me and was disappointed with this.

You are all missing the point, it should be customers choice, not pro shop. Have had over a hundred balls drilled zero scribed and no accuracy issues.

That you know of. 

What I have seen is if the line is there for the customer to see after it is drilled the ball driller will go the extra mile to make sure that the dimensions are accurate and that they do hit it.  That is almost like an advertisement to the accuracy of the ball driller, as long as the scribed line is in the correct location.

Don't get me wrong.  If you don't want the scribed line then you MUST say something up front.  Once the lines are in the ball it is yours if you do not tell the ball driller first.  It will not offend the operator if you don't want the scribed lines.

I would of told him not to scribe ball if I knew that's what they do, but have never had anyone ever scribe a ball before, so why would I think to tell someone not to do something that I'm not aware of that that do, it would make more since that pro shop telling me this is what they do upfront

Agreed that I spent a few moments of shock when I saw my first scribed ball, but I got over it. I also agree that you must "assume" a grease marked ball is the same. At least around here, now that I have my own span and pitch gauges, I GUARANTEE you none of my non-scribed balls that were supposedly matched are equal. I'm just not high enough caliber to have noticed it before.

Brickguy221,

I know there are some who can actually feel 1/16", and I know there are those who say they can, but can't actually pinpoint what feels different to them.

I've measured balls that the owners say the span is off that are either "dead on" or as close as it gets.  If something still feels different I can usually bevel the thumb hole a little and then the span feels "perfect" to the same guy who insisted it was "off".  In other words, sometimes it's not even the span.

To those to don't like scribe lines, the driller doesn't need to scribe the whole grip center line, etc.  All he should need is a few very small marks to tell him the cut spots.  The rest can be done in pencil.  These small markings are barely noticeable.

I agree and have done this for customers.  Good Point!!

I assume we're taking for granted that the lines were in the proper place to begin with.  I'd say it was more important to measure the span correctly (which is an inexact science to begin with) than the actual drill.  Hell, if you miss the line, might make a better fit.

I scribe because I sweat when I drill, and the droplets coming off my head smear the grease lines lol  No issue with that when scribing!

Hey TJ,

Not to hijack the thread but I noticed your signature not reflecting as being the brand manager for 900 Global. Are you still with them?

It's a line not a moving target

+1 ... my point all along.....

And for being 1/16 off, there is NO excuse for that. I've had a slew of balls drilled over my years and the driller that simply eyeballs the bit lining up with the line and drills will be off more than he will be on target. The driller that uses a razor blade or similar device to line up the bit with the line will be dead on every time. I have never had a ball being off even 1/32 when the driller uses the razor blade or similar object method.

Here's a old article I thought I'd throw in:

A Look Inside the PBA’s Mobile Service Trucks
http://news.pba.com/post/2001/10/19/A-Look-Inside-the-PBAe28099s-Mobile-Service-Trucks.aspx


excerpt:
 "Most pro shops use a grease pencil to mark the balls for drilling," Snellbaker says. "Scribing is much better, since it leaves a permanent record of the work and allows greater accuracy. We drill with an accuracy of 128th of an inch."

Lane, the bottom line is that there is simply NO EXCUSE for ever being 1/16 off. Mark the ball right with a scribe or the thinnest line possible with a pencil, line up bit right and the drilling will be right every time. Use wide lines, eyeball the bit lining up with the line and the drilling will be off more times than right.

So wouldn't it make sense to draw your lines so your not drilling for the bit edge to touch the line or,  cut to cut,  but instead drill total where you center the drill bit up on the line instead
