Radius of the cut of a leather wrap

Just the way I quickly sketched out my drawing. I believe you make a good point and the 2's in r = d/2 cancel each other out and diameters works just fine, I think.

Thanks!

why is there a radius??

Because if you are wrapping a cone or tapered cylinder using a piece of material with parallel straight lines at each end, the wrap will come together short of the wrap channel when it meets on the small end of the cone leaving a small gap and will be long hanging down below the wrap channel on the wide end.

I have a metal template and find it to be useful on some cues and worthless on others since the taper of the handle can vary a lot. The template assumes all cues are tapered the same. It was a perfect fit on a Meucci and way off on a Schon.

I had always wondered how how they were supposed to be "universal" I found out (as I had suspected), they most certainly are not.

I understand what you are saying but it seems to me that all 4 sides of the wrap material would be straight.......... the sides would be tapered......... but I don't see a radius or a curve .................

Obviously I asked too complicated of a question for you people. Why is it every time someone asks me a question I try to help them out as much as possible but when I ask something I have ten f*cking idiots chiming in with useless shit and being f*cking morons? If it was so easy to f*cking google it I would have had it already but instead I spent most of the day looking it up and still am no further along.


I am so f*cking tired of seeing some one say every two seconds google it. Every time I see it i just want to tell the person to go f*ck themselves. I mean seriously.

This is how my day started. I got up and and had this really great idea. But I needed an exact number to feed into my 3d rendering software so I could have the part built. So the first thing I did was spend an hour onl AZBilliards looking through old posts trying to find if it had ever been answered before. I know it had been asked before because I asked it and all I got was a bunch of *ssholes saying google it.

So then I went to google and spent another two hours just searching for anything even remotely close to what I am looking for. I found bits and pieces here and there but nothing definitive. So after two hours of searching google I figured well maybe I can ask a simple f*cking question and get a simple f*cking answer on AZBilliards. (I know your thinking, yeah right, that will work.)

Then the first reply I get is someone saying how superior they are to me because its "a relatively simple math calculation" And they ask if I need more clues? Really if I was there I would choke the f*ck out of them with my bare hands, but I'm not. Do I need more clues? Yes obviously I do. I google "simple f*cking math" and it came up way short of anything useful just like the reply I got from him!

Then he tells me to google it. F*ck you. I did google it. At this point I have been on google more today than I have been getting stuff done because of the stellar f*cking help I got from here saying google it.

Then I get someone saying "I don't think he knows what a radius is" Again F*ck you. Seriously? You're going to f*ck with me because I used a word that everyone in the industry uses. Go f*ck yourself. Then someone attaches pictures. I know how to find the radius of the f*cking circle it s the radius of the cut I cant figure out. Again if it's so f*cking easy why not just say how to do it instead of acting like a superior *sshole.

So now its 10 pm I have worked off an on all day trying to figure it out and have spent about 7 or 8 hours collectively researching it. I still have no Idea what the answer is.

At this point I have just given up hope that anyone at AZBilliards knows the answer and there is just a bunch of trolls with nothing better to do than f*ck with someone who needed a little bit of help. Why don't you guys just go to the hospital or old folks home and start pushing people down the stairs too. Self righteous pr*cks.

All you do by saying google it is show that either A you don't know the answer and should have kept your mouth shut in the first place, or B you know the answer and want to act like a self righteous *sshole and should have kept your mouth shut.

Dont give me the bullsh*t sob story that you spent a hundred years learning your craft. You didn't invent the f*cking wheel, you. And since 90 percent of the cues on the market today are made in mostly the same way, You got help from someone else, because you cant tell me every single person who ever built a cue came up with the exact same ideas on their own. Give me a break!!! All saying that does is prove your and idiot or an *sshole.

I realise that there are people out there way smarter than I am. I also realise that there are people that have spent many years, and a lot of money, perfecting the trade. However if you are so worried about giving out the radius of a f*cking cut on a wrap you will never touch and has no bearing on your business in any way, Then I feel sorry for you.

Now if there is anyone who actually either knows the answer, Knows how to get the answer and is willing to help, or Has a wrap fixture and wouldn't mind taking a couple seconds to take a few measurements. I would greatly appreciate it.

If all you are going to do is troll and act like an asshole then move along.

Who would have thunk the post of the year would come in at the eleventh hour on new years eve?

Cammel,

I have two wrap cutting jigs and the curves or radii match almost perfect.

It seems to me that someone else is already done this math calculation for us and gave us the tool to cut the wraps.

The radii that occur are already there on the fixtures.

It would take a big circle to capture the radius.

Every cue maker has a different A Joint and handle size at the butt sleeve. My A Joint geometry is only 1.004 and is smaller than most cues. Having said that, I have found the the stretch factor of most wraps allows for me to glue the contour perfectly to the cue. When using snake or lizard material without stretch, it is not as easy on the ends and I must trim cut a hair to compensate on the seam end.

This thread is very important to me because I would like to have the radii changed on my adjustable cutting jig to match my cue exactly. My other jig I would leave alone for thicker handles on other cues.

I have done wraps for customers with A joints at a more convential 1.024 or so dia. and it is my guess that 1.024 is about the size these radii on the cutting fixtures were designed around.

JMO,

Rick

As you can see by the over emphasized drawing, the ends of the wrap are actually arced.

Solid Geometry... Google "frustum" and read all about it.

Good luck.
Linear forearm and curved handle.
 
The formula is the same as making cones for 2 stroke tuned pipes.
KJ really was trying to help the OP to learn how to learn, in effect offering a lot more than offering the formula for one situation.

You put on a good rant. Exposing your limitations took guts.
Apparently you didn't spend enough time 'AZ searching' because I have previously laid-out
the calculations for 'wrap-radius' about two yrs. ago. Whether or not you find it is irrelevant.
It involves nothing more than what I would call SHOP MATH. I took the class in about 8th, 9th grade.
It doesn't require data being plugged into a 'program' and for the most part, you wouldn't need
a calculator except that PI is involved. Since you didn't like my suggestion that it's math
that you should LEARN, I then suggested that you Google it. I know, you couldn't find it there either.
A very usable set of calculations was found where ??? GOOGLE.

I knew that when you wanted me to write out the formula for you that you would be a PITA.
You don't want to learn, you want to be 'spoon-fed'. I don't do that; I show you HOW to learn.
Instant gratification is not learning. In a year from now you could be asking the same question again.

I'm not particularly interested in what you think of me.
I didn't come here to make friends and I'm not running for public office.
I gave you what you needed to become more knowledgeable and you respond with name-calling.
Sounds about right. Good Luck with your project. Don't forget about GooGle.

You can use math, to work out the radius of the wrap curve.
But using a good ol' ruler and paper and tracing my unique wrap template, I can tell you that the edge is about 0,5mm taller than the center.
 
This is on my beat up house cue.
I actually cut the leather some 1MM short.
I glued it from the bottom first. I hate gluing from the top these days.
I don't follow how they teach it on the two commercial videos out there.
Wasted too many leathers doing it their way.
I tried white glue and melamine glue as well. Settled on magic sauce now.
Most imperfections in the radius can be fixed by careful installation imo.

Great looking wrap Joey.

Could you provide some further detail on "gluing from the bottom" vs gluing from the top, please?

Thanx

Thnx Dale.
I glue from the butt end first then to the A-joint end.
I figure the grip end is more crucial than the top end.
Plus, it's easie to manipulate a smaller surface ( if needed ) than a bigger gluing surface.

Btw, I've seen leather work by Kenny Koo, Dave Barenbrugge, Mike Webb. Tascarella, Searing , TW and Gina that just boggles me how clean they are .
