veneer rings

[...]

You keep bringing up the wrap around issue [...]

"Wrap around issue"? What the hell are you talking about, Rick? You're the one whose been blathering on and on about rotary work and wrapping designs around cues - I haven't mentioned it even ONCE in this thread.

Again, I prefer you not put your words in my mouth so you have something to argue against.

[...]
For example, last night I cut of 80 parts to Z -.110 on a 1.200 x 6" slab and it took 59 minutes. If someone is not doing multiple production cues and needs to make a huge amount of parts, how much time does it take to mount another slab and align the orientation to the machine coordinates? Two minutes, so where is that a limitation. We're really splitting hairs here aren't we.

So there it is.

Rick

Wow, you really ARE limited in the depth and breadth of your imagination, aren't you Rick.

You have no idea what can be done in inlay work when you AREN'T limited to a tiny little width on your X-axis. Your examples of how you do things and why you don't feel limited with your machine simply shout volumes about just how much you DON'T know.

You've brought up Jake, who actually DOES have a great imagination, so why don't you pose the question to him. Ask Jake if he would EVER - from his very first day of cuemaking - be satisfied with 1.4 inches of travel on one of his machine axes.

I'm not a "production" cuemaker either, but I do things in almost every cue I build that call for a large work envelope on my 3-axis machine. The fact that YOU don't know why that is so useful - actually necessary - does NOT mean it's of no value. It simply means you don't know enough to know what you don't know.

I am sure if I remove that gear back lash, my Radial geometry programs will produce very accurate results. Will try that and see what happens.

What CAD/CAM program are you using to create your "Radial Geometry" programs?

TW,

This forum is all about people coming together to share ideas and comment about cue making. You made some comment and I posted an opinion and review of a machine and a company that builds same. Comparing the economics of your DIY machine to a custom design build machine engineered for cue makers makes no sense to me. Why? Because a business has a ton of expenses that any DIY person is burdened by working in his basement. That's all.

Now you say I am changing the subject because I answer some direct question or aqua actions. Boulderdash!!

So you berate a company because you don't like the parameters of their design and now me because I share my views with the forum. I personally don't care that you say things like, "I don't know what I don't know" because there in some truth in what you say. I am someone who has only been doing inlays for 2 years. In that time no one can expect to attain expert knowledge.

There are many things that I have attained a great deal of experience in over my 60 years on this planet and the are things that I am considered to be an expert by reputation. So not being expert status in all the facets of using CNC is not something that I or anyone else should expect to gain in doing 40 to 50 cues.

So now where does it leave the discussion. Allow me to expound on the attributes of Uniques Product called the Cue Monster. I will not dwell on any negative aspect of same and will acknowledge your disdain for less than the 1.5 Y travel. To me it is not that big of a deal but WTF do I know.

You say there are things that you do on the CNC that I can't or don't understand or have a clue. While I only use my CNC for inlay type work these days because of other dedicated machines and fixtures I use in my shop, here are operations I have done with a great degree of accuracy on Unique's Machine.

Turn Shafts
Turn butts
Cutting point grooves in forearm utilizing the offset feature that moves the datum of the Y envelop
Squared up point stock blanks using table fixture clamping device
Milled 90 degree angles on veneer stacks edges for mitering point assemblies using table fixture
Engraving
Nesting Parts
Cutting wrap groove edges after installing rough wrap groove with my saw machine
Milling simple parts I needed
Cutting parts out if stacked veneer combos for bridging points.
Slotting ring billets
Experimenting with 4 axis work freezing the Y using the x, a and z after plotting the geometry within the circumference of the specific area of the cue's longitudinal area and taper parameters.

I am sure I am forgetting some things but my point is during all of these functions. Are those the things you were referring to that you do on your DIY machine that I was not capable if understanding in my limited little brain. Your a funny guy TW, why ?, cause you make me laugh out loud. A belly laugh. Laughing is good for one's soul and well being so I thank you for that buddy!

While I acknowledge your machine must be a beast with off the wall state of the art stuff going on, that does not give you the right to knock someone else's work as a machine designer and his offering. While you certainly have the right to express your opinions the is an area, most would agree it serves no purpose and is in bad taste exposing the sour grapes component of your being.

Here is a example to that expression.

Since I was a kid I have been involve in many maritime activities and as an adult recieved my Coast Guard Captains Licence. I raced in 13 meter sailboats for many years and own and operated commercial vessels on Lake Michigan. So what I am about to say is based on fifty years of gained knowledge and experience as a Marine ameture and then professional for for over 30 years. This comparison is Germaine to the subject at hand and is the best analogy I can offer describing the Cue Monster and your disdain for same as is surly noted in this thread and archived for anyone who want to go back and sift through the minutia.

Boats are what I will use for my analogy as they are a functional item that has many design features and parameters for many different application secenerios.

There are basically two types of vessels, motor powered and sail powered. We will catoragize oar power as motor just for the record.

There are many types of sailboat designs ranging from windmills, sloops, ketches, windjammers, cutters, catamarans and the list goes on. Today the fastest racers are the 22 meter America's Cup Catamarans that are the pinnacle of speed and reduced drag on all surfaces both in and out if the water.

There are also many type of motorboats designs, speed, cruiser, tug, cargo, liner, ferry and this list also goes on.

So what is Rick's point you may inquire at this point?

While there are sailboats that do many things very well within their specific design criterial and motor boat that do many things well they must be viewed and judged within the parameters of there design and functionality.

Then there is some thing called a Motor-sailor. This unit sails and also motors with functionality but it does not compete well when compared to boat specifically designed within a certain envelop . The guy that owns one of these babies understand that there are some limitations but when he wants to motor or sail his boat he can do just that.

So if you take all the people that own Uniques Cue Monster they will tell you that they understand that it has some limitations concerning the y envelope and the worm gear backlash on the A axis but those thing are just part if the ability to motor or sail.

I am sure your index on you X does not have the capacity to be belted to a DC drive motor to spin your cue at a turning rpm rate. The Cue Monster can do that. So why you may need your working platform to include a different station for turning the cue monster does not.

Anyone who own one if these machines does not expect to compete with a world record holding 22 meter racing catamarans. They are fine with having a motor sailor.

So you critical or jaundice eye can be compared to Dennis Connor or Ted Turner being critical about someone who operated a motor sailor. You would never see world class America's Cup racing champions making such a comments because it would certainly serve no purpose and would be viewed as sour grape and bad form.

Not where does that put you Mr. Solipsist. Sour grapes for not good reason I say!

JMO,

Rick

I know we're getting off topic here, but I feel the need to point this out.

This line in your previous post is a clue to the part where Thomas says that you don't know that you don't know.

I'll just put it this way, but keep in mind that this is my understanding. Not from personal experience doing it, as I have not, but this comes from my research into this amazing subject that so few really understand. Personally, I've not met a machinist who understood it. They all thought they did, but after talking it through they realized they were missing a crucial component.


To do rotary part and pocket inlays, and have them fit properly, requires 4 Axis machining.

They call it 4 axis machining because it is using all 4 axis during the machining process. Just as you call normal part and pocket inlaying 2 axis. Many call it 2 1/2 axis due to the stand alone use of the Z.

I suspect that what you think is backlash in your rotary axis is actually your missing 4th axis of motion.

If anyone cares at this point.............. my veneer rings came out just fine.... I did have to do a little work around because of the short Y axis but I am happy...........

I hope you are all happy too...............

Royce,

You may be correct about my observation concerning the worm gear backlash issue I describe because when I drew my geometry on Bobcad in 2d and then warped it, it came out distorted. I may have screwed up the taper and circumference components. So in reality after pondering this issue I never got to the point where the geometry was proven. And only then could I judge the backlash error that I think will be there in the end.

Now Allen has brought his Gibbs software into my shop and he can create geometry on a tapered cylinder (cone) in what he refers to acquiring the geometry in a wrapped state. So in reality you need the 5 axis option on Gibbs to program radial geometry on the taper when actually you are using 3 axis of your 4 axis machine because y is frozen. Y is relevant because it must remain at 0 while A, X and Z move simultaneously.

The Unique Cue Monster overall set up will doubtless not be the machine to produce this kind of work and I get that. I can modify that machine by removing the worm gear and eliminating the back lash then test the complete geometry and see what happens. We think we can make it work on the Cue Monster but just how accurate the work will be revealed will then cause me to go to a new machine designed for higher accuracy concerning this type of work. I will keep the Cue monster I am sure at it a useful tool.

Again Royce, I am no expert just an CNC apprentice guy who is learning how to make this work. Then and only then will i focus on the design aspects and marry these things for my work. This stuff is fun for me and keeps me young. Retirement is not something for me, I like to keep myself occupied with a positive attitude.

Kim,

I would like to be happy but I would need to see the veneer rings cut in blue.

Why did you start a thread on such a dangerous topic as cutting veneer rings? Have we all not seen enough blood in our life time? ;)
 
If your rotary has backlash as significant as you think it is then it would show up in your typical flat bottom cue pockets. An endmill moving in the +-y direction would be pushing the cue around enough that it would bottom out the slack in the A axis. I'm going to guess that you definitely have backlash but not so much you cant rotary machine.

Also, believe it or not....you dont have to have Gibbs 5 axis to accomplish what you described as rotary machining. Regardless if he does wrap wireframe and uses a ramping Z....the part and pocket aint gonna fit right
 
Jake,

I have not noticed any problems in the 2 d inlays I have done as I get a very tight fit up and the side walls appear to be very plumb. I do understand what you are saying in concept and also your logic. I don't know how familiar you are with the design of the A drive system on the Cue Monster but that stepper motor is mounted on a thick hinge bracket with a levered moment arm creating a downward force on the gear engagement of the drive when the A is static.

I just put a scale under the deal and tried to weigh the down force and it appears to be about 3 lbs. Maybe this loading within the gears supplies enough overburden to overcome the lateral force of the micro mill during the pocketing. I think that is the case. Also the large gear does not have a typical V type fit and the pitch angle transitions into a round surface at the bottom for a max surface area footprint engagement with out gaps.

Allen did what he called a potato chip geometry and alas it was not fitting too well from the job done on my machine. Pretty bad. He took a test butt I made for him a ran that program on a Haas 4 axis mill and it fit up pretty tidy. There may have been some tweaking adjustments i don't know.

Allen is 40 years old and has been doing this stuff his entire adult life since he was in his teens and some of the metal speciality parts I have seen that he has done using radial geometry is just way beyond my understanding of the concept.

When I told him about TW's so called secrets, he laughed and said that anything that one man can do regarding a machining operation any talented pro with experience can create or duplicate it and anyone who thinks otherwise is smoking crack or a nut case. He says "give me a drawing or concept and he will make it happen". There has never been a time where he has failed to perform a machining job that has been presented to him. Just do it or go home is his saying.

Also there seems to be more options and ways to skin certain cats if you will.

Again, I am not an expert or professional machinist and don't claim to be more than an interested observer in this area. Alan has joined my team as the CNC expert for projects other than the 2d stuff I do. At this point we are making a purple heart Wooden Wedding anniversity cue for his wife with some wild exotic wood inlays creating very unique patterns that reveal the cross gains of the wood using the 4d. My partner Ken the Cue artist has some off the wall eclectic designs that will also be be given to Allen for doing the geometrics of the next cue with a modern Art Deco / Marquetry feel that creates spatial optical illusions.

I will be posting these cues in the near future and people can view the fit ups Alan can produce and judge them first hand.

Rick,

Debating anything – ANYTHING – with you is a huge waste of time, because you constantly try to shift the focus away from the one or two salient issues to bullshit that has nothing to do with the thread topic.

However I do want to address a few of your repeat digressions, after which I’ll try to go back to ignoring The Crazy Rick show.

Comparing the economics of your DIY machine to a custom design build machine engineered for cue makers makes no sense to me. Why? Because a business has a ton of expenses that any DIY person is burdened by working in his basement. That's all.

The very reason it makes sense for a cuemaker (or any small business with machining capabilities) to build their own CNC machinery is EXACTLY because of the economics of paying a separate entity to do it for them. That “ton of expenses” that the commercial CNC company stacks on top of the cost to build a machine puts it just that much farther out of reach for the average beginner/wannabee cuemaker.

Also, you keep bringing up working in one’s “basement”, and you’ve implied that’s what I do. I have a stand-alone shop on my property with a separated finishing room, and I have a ground-floor office in one of the four bedrooms of our house. Pool table for test driving is in the basement rec room.


Now you say I am changing the subject because I answer some direct question or aqua actions. Boulderdash!!

The word is balderdash. “Boulderdash” is a chain of rock-climbing gyms.

So you berate a company because you don't like the parameters of their design...

I didn’t “berate” the company at all. The word “berate” means – exactly - “to scold or criticize (someone) angrily.” As usual you’ve employed a word that you think makes you sound intelligent, but you actually don’t know what the word means and are too lazy to look it up.

I did criticize (though not “angrily”) the idea of a CNC machine for doing industrial-grade work that has and axis limit of 1.4 inches. And I did write that I thought their prices are too high for the value received. These are reasonable comments that any informed person might make, were not made in anger or in an attempt to “scold” anyone, and can only be characterized as “berating” by someone who is too stupid to know what the word “berate” actually means.

I personally don't care that you say things like, "I don't know what I don't know" because there in some truth in what you say. I am someone who has only been doing inlays for 2 years. In that time no one can expect to attain expert knowledge.

True, no one can expect to attain expert knowledge in such a short time... which makes me wonder why you tend to pontificate about such things as if you ARE an expert, when in fact you are – at best – marginally competent.


[...] I am sure I am forgetting some things but my point is during all of these functions.[...]

Um... huh?

While I acknowledge your machine must be a beast with off the wall state of the art stuff going on, that does not give you the right to knock someone else's work as a machine designer and his offering. While you certainly have the right to express your opinions the is an area where most would agree it serves no purpose and is in bad taste exposing the sour grapes component of your being.

If the design of a machine is severely limited and overpriced in my opinion then I very much DO have the right to express that opinion in a forum of the nature.

Now, you’ve used – er, actually misused - the term “sour grapes” so many times here that I guess I should address it. The term “sour grapes” comes from Aesop’s tale “The Fox and the Grapes, in which a hungry fox is unable to reach a cluster of grapes because they are higher up on the vine than he can jump. So to compensate for his disappointment he declares that those particular grapes aren’t even ripe yet, and must be sour, so he doesn’t really want them anyway.

The term is used specifically to describe a person speaking negatively about something that he would like to have but cannot attain. So in order for it to apply to what I have said about the Unique machine that is a subject of this thread, that machine would have to be something I want but cannot attain.

Therefor, your use of the term “sour grapes” is markedly incorrect – as are many words and terms you sprinkle into your writing. I certainly CAN attain a Unique machine with a 1.4 inch X-axis. I could either buy it used OR at it’s excessive new price – if I wanted to.

But I don’t. I don’t want to because I have no use for it. The very first machine I ever built was more versatile, and every machine I’ve built since is far more advanced than that machine. So no “sour grapes” here.


Since I was a kid [...] Zzzzzzzzzzzz [...]
So what is Rick's point you may inquire at this point?

Oh God, if only I had a nickel for every time I’ve asked that question.

I am sure your indexed on you X does not have the capacity to be belted to a DC drive motor and spin you your cue at a turning rpm rate.

On my first machine I had exactly that capability. Subsequently I came to realize that an all-in-one machine can be VERY limiting – much like the Shopsmith woodworking “station” that can be a tablesaw, bandsaw, lathe, grinder, drill press, etc. It looks great when you see it demonstrated at the county fair. But the first time you switch it over to a tablesaw, only to realize you should have turned all the table legs first (or whatever) you suddenly realize how much easier and cleaner it would be if you had a drill press over there, a tablesaw over hear, a lathe in the corner, and so on.

So I have 4 CNC machine – 2 mills and 2 lathes – with a fifth machine in the works and a sixth machine in the designing stages. I never have to change out one setup to do a separate operation because I always have another machine that can to that for me.

Not where does that put you Mr. Solipsist. Sour grapes for not good reason I say!

Yes, I believe I’ve already pointed that out. You say “sour grapes”, but you haven’t a clue what it means, so you have no good reason (I refuse to believe that flat out stupidity is a good reason).

Sure, any competent machinist can find a way to replicate an existing part or an existing operation if he's given the opportunity to study it. That's simple imitation.

The secrets (not "secretes", which is an entirely different thing) involve knowing what the parts look like to begin with - when no one else has ever made such parts before. The secrets are discovering the operations when no one else has done those operations before.

Anyone can imitate. It takes w whole other breed of cat to innovate.

I will be posting these cues in the near future and people can view the fit ups Alan can produce and judge them first hand.

Okay,,, not that it matters, but is it "Allen" or "Alan"? And is Allen/Alan aware that you don't know how to spell his name, now that he's joined your "team" and all?

TW
(PS: Your description - and therefore your understanding - of true 4-axis work (in which all 4 axes remain active) and 5-axis programming is so incorrect as to be laughable. You clearly have NO idea what you're talking about in that regard.)

TW,

So does "anyone can imitate" mean your reference to your so called secrets are not so secret as you thought or that you can do Southwest Copy Cat Cues and still think you are not like every other CM who has done that. FYI, Alan has never seen one if your cues and it was he who came to me regarding this 4 axis stuff as his wife is an artist and she drew up some designs that Al worked with. Until yesterday he never heard your name, just for the record.

Not that it matters to me at all but talk about the pot calling the kettle black. (No reference to Richard Black should you wish to go off on another one of your tangents). LOL.

Alan is the correct spelling and yes he knows I screw up his name all the time. Relevance?

Call Gibbs support tech and find out for yourself.

You might not be able to do something like that? Professionals have that utility however as they don't use pirate software.

As I said TW, I, like many others here am only an interested observer who is learning. That seems to really bother you for some reason? Why?

JMO,

Rick

Not secrete, for crying out loud .
Do we even need to tell you what secrete means ?
It's not of coarse, it's of course .
It's not "your so full of yourself".
It's you're as in you are.

If you're going to debate, at least don't misspell real simple words.
Better yet, let it slide already.
