Dungeons & Dragons Dice

I’m a huge fan of dice of all kinds, but Dungeons & Dragons dice in particular. Casino dice just don’t do it for me — in my mind that’s just the crummy six-sided dice that are in every board game I ever owned as a child. But D&D dice are something different entirely, they’re the portal into an awesome world of imagination and storytelling.

I remember being really into Dungeons & Dragons before I ever played it — before, in fact, I really knew entirely what is was. I have no idea where I first heard of D&D or what attracted me to the name, but when I was in junior high my brother and I decided that we wanted to play. We went to the local B. Dalton book store and looked through their two shelved filled with Dungeons & Dragons books. At the time, that seemed like so many.

I remember most of the books were Advanced Dungeons & Dragons, and we certainly didn’t feel we were ready for advanced yet, so we finally found a boxed set that was just labeled Dungeons & Dragons — Hollow World. It said it had everything you needed to play in Hollow World.

Of course anyone at all familiar with D&D knows all the mistakes that happened here. Hollow World was just a setting, and it did not have everything you needed, because at the very least you needed the player’s handbook and some dice to play the game at all, and preferably the DMG as well (since that’s where all the magic items were). Nevertheless, we poured over that Hollow World boxed set and tried as hard as we could to deconstruct the rules based off of the references. Since they introduced some new races (and we thought it was weird that there were no dwarves or elves or humans in D&D, but oh well) we were able to get a decent feel for the character creation process. Of course the only dice we had were the old d6s from board games, but somehow we managed (though it was very clear from the rule that we were supposed to have special D&D dice).

In the end what we played was not Dungeons & Dragons by the rules — not at all. But it was a fantasy RPG. We played, and when we played it was mostly roleplaying and not much combat, which we didn’t really understand that well from the rules.

I do recall that at some point my brother discovered a store that was still not really a game store, but it had a lot more gaming stuff in it — including the all important Dungeons & Dragons dice. So at long last we had those strange and wonderful dice in our hands to do our gaming with — in particular the d20, which at the time was the talisman of D&D to me.

Of course I still game today, though I almost never play Dungeons & Dragons. But the look and feel of those D&D dice is still somehow magical and wonderful.

Forging Companies

I have to say, of all the clients that I work with regularly at my day job, I kinda like the forging companies the most, or at least one in particular. Well, there are other clients that I like too, but the open die forging place is definitely very high on the list — the guys who make forged crankshafts and rounds and blocks. Part of this is that I like the client contact. He’s a nice guy, he’s easy to work with, we chat a bit but not very much and the meetings rarely take more than 20 minutes.

Their actual industry, custom open die forgings, isn’t terribly interesting as these things go. Forging is an industrial industry, and none of the industrial manufacturers are super interesting from a business standpoint. In fact pretty much across the board the consumer manufacturers and resellers are the more interesting product lines to talk about.

But the nice thing about custom forgings is that it’s not a very competitive industry. There might be a lot of forges out there, but it’s nothing compared to, say, jewelry shops or plumbers. Not only that but these guys have a very specific niche within the custom forging industry: they aren’t huge and they don’t try to compete on price at all. In fact they openly acknowledge that for many types of custom forgings they’re more expensive. However, what they have is very fast turnaround times.

In the forging industry, a chunk of the business is crankshafts. Not just making crankshafts for new things, but making crankshaft to replace old ones that have died. And most forged crankshaft manufacturers have really long lead times. When you have some giant industrial press that’s shut down because the crankshaft went out, you care a lot more about lead time than price, especially when the difference is often a couple weeks vs a few months.

So we have a nice client with an uninteresting industry, but a low competition one and a very specific niche that even fewer people try to compete for. It means making progress in promoting the company is easier, and the process is pleasant.

Holiday Shopping

The holiday season is nearly upon us, and that means getting holiday shopping done. This is not something that I’ve been that historically great at. In point of fact, nearly every year I’m out on the day before Christmas Eve trying to finish off my shopping. Every year I decide to get an earlier start this time, and every year I’m out again at the last second.

What happens is this: I decide to do my shopping early and online, and I even go so far as to look online and find gifts. But usually I’m vacillating between a couple of possible gift ideas for one person and let it sit for a few days while I decide which to get. Then a few days turns into a week or two and I suddenly realize that while I still have some time before Christmas, I’ve passed the line where I can no longer order online and expect to get it shipped in time.

Suddenly I have to do shopping the old fashioned way — again. And that means I have to wait for a weekend when I have some time to go out, and suddenly it’s a couple days before Christmas, I finally have a day off of work, and I’m desperately looking for whatever’s in stock.

Oh, and I should mention that it sucks to shop that late because it’s so late and you absolutely must get something right now. On the other hand, the stores are not crowded at all. It’s actually kind of pleasant, other than the pressure. There’s only so much shopping you can fit in the day, and if you don’t find something you can’t just go somewhere else.

So this year, I’ve still got some time. I’m totally going to buy online for everyone, or almost everyone. If I’m not sure which of two things to get I’m going to make like it’s Christmas Eve and I have no choice but to buy one of them now.

Of course I’ve said all that before, so we’ll see.

Zip Ties

Okay, remember when I talked about the work client company that did twist ties, and I mentioned that twist ties weren’t all they did. Well I’m currently working with them on filling out their product line descriptions for zip ties, and I have to say there’s a lot more to zip ties than meets the eye.

The general concept is pretty simple and the standard zip tie is exactly what we all know: loop of plastic, pull the tail through the head and zip it shut to hold your stuff together. Use ‘em to bundle your computer cables or hang a sign on a chain-link fence.

But it turns out that the world of zip ties has advanced technologically since the invention, and there are a bunch of variations of zip ties out there on the market now. Naturally you have the standard zip ties that come in various different lengths and widths and thicknesses (and colors — can’t forget the color variety). I have to assume that over 90% of the zip ties sold are these basic zip ties, and they’re even used by police as makeshift handcuffs.

I was poking around the interwebs on zip tie stuff and found the Zip Tie Guy — a site that collects some of the odd stuff that zip ties have been used for — including zip tie dresses and lights and chairs built out of zip ties. Definitely worth a read!

But there is more than just your grandfather’s zip tie. Here are some of the other kinds I’ve learned about:

  • Releasable Zip Ties: These work just like standard zip ties, except the head that locks the zip tie has a wee little hinge on it that can open up and release the zip tie, making it reusable. I have to wonder just how often you can reuse the releasable zip ties — that tiny plastic hinge certainly won’t last forever — but even a handful of uses makes it much nicer, especially since it’s nearly as cheap as normal zip ties. And of course you don’t need a knife or scissors to remove it.
  • Beaded Zip Ties: These are really different from normal zip ties, but the principle is the same. Instead of a strip of plastic with teeth on one end, the entire thing is a series of beads and looks a bit like a cheap bracelet. At one end is a head with two connecting holes, one larger that the beads can fit through, and one smaller that only the space between the beads can fit in. Thus it’s effectively a releasable and reusable zip tie in itself, although massively weaker since the thin point between the beads is very thin indeed.
  • Ladder Cable Ties: You can’t even really call these things zip ties, though they’re in the same family. These are a metal strip that really looks like a ladder. Like normal zip ties you feed the tail through the head and cinch it up as tightly as you want, but being made of metal these are much stronger and are less easily cut. This type of zip tie is used a lot in construction, and often used as a redundancy device to strap something in just in case it falls over, the ladder tie will catch it.

There are other varieties as well, but most of the rest are smaller variations than these three big ones. Things like zip ties that have an area that you can write on, or zip ties that are tear off so that you can literally break them just by grabbing and pulling. There are even lockable zip ties, though I’m not really clear on exactly how those work.

I have to say though, after spending an afternoon learning all about zip ties, I’m still a fan of the basic design. It works, it’s simple, and it’s cheap. What more can you ask for?

Vertical Machining Center | 5 Axis CNC Machine

I’ve talked a bit before about machining equipment and how we work with a lot of machine shops at my work. The nice thing about this is I often feel like I have a pretty good handle on the whole CNC machining terminology, working with enough of it day in and day out. As always, just when I feel like I understand a section of the industrial market, I come across something to prove that I don’t know what I thought I knew. In this case it has to do with both vertical machining centers and 5 axis CNC machines — both coming from the same client.

So, in less than 20 minutes (since I wasted some time on that intro paragraph) here’s what I’ve learned about these two concepts that, it turns out, are thoroughly known by anyone in the machining industry.

Vertical Machining Center

The client I was talking to was using the term vertical machining center a lot. I did some research online and learned that the term is not just very common, but it’s also a significantly searched term on Google. The problem I had was literally no site I could find explained what the heck a vertical machining center actually was. I found the same issue with 5 axis CNC machining, it’s worth noting. Everyone brags about their 5 axis CNC machining capabilities, but they all assume that if you’re looking for it you already know what it is.

But starting with vertical machining centers. Despite that fact that they called “machining centers” — something that makes me think of large buildings filled with CNC machines — it’s actually a single CNC machine. Also, the machine does not necessarily have a vertical orientation.

Instead the vertical machining center just refers to a CNC machine in which the cutting element — the thing that actually cuts the metal — is aligned vertically. Think of a drill press — the drill bit is oriented up and down, vertically. Apparently there are also machining centers (which again are just a single CNC machine) in which the cutting element is aligned horizontally. Unsurprisingly these are horizontal machining centers.

I never did get a good answer on why they’re called machining centers, rather than just machines — which is after all what they are.

5 Axis CNC Machines

So I’ve been hearing the term 5 axis CNC machine forever, and in fact most vertical machining centers are in fact 5 axis CNC machines. My issue with this terms is what the heck are your 4th and 5th axis? I mean, 3 axis CNC machines (which are also a thing) I can get. You’re able to move up and down, forward and backward, and side to side.

Right there you have it, all three dimensions. You don’t get more than that without making up things, like time as the 4th dimension, for example. So how the heck can you have more than those 3 axis? You can move everywhere with just those three.

Well, the explanation actually makes a lot of sense. In a 5 axis CNC machine the surface that holds the item being cut can move along the normal X, Y and Z axis (side to side, forward and back, up and down) but in addition to that it can also rotate along the X and Y axis. Once you picture that in your mind you can see how it does indeed allow for additional motion that can’t be replicated with just 3 axis.

Apparently the reason this is desirable is that it lets your vertical machining center machine more complex parts without having to stop and change the setup of the vise that’s holding the metal being machined. This is important not just because it means you get the job done faster, but because it adds precision to the machining job. If you stop and manually adjust the vises and actually reset the object being machined, you’re inevitably going to get it positioned slightly differently — it’s just not possible to set it up perfectly. So the 5 axis CNC machine lets everything cut from one single setup, giving a lot more precision.

And darn it all — I went over 20 minutes. I need to use fewer words.

 

Twist Ties Are Not That Complicated

I always enjoy the break from heavy industrial topics at work, when we get one of those rare clients that is not in the industrial industry. Almost without exception their business is far easier to understand to the layperson. Case in point I’m working with a client that literally sells twist ties. Yup, those little things that tie your bread packages closed.

Don’t get me wrong, SupplyPlaza does more than just sell twist ties, but almost everything they work with is in a similar vein to twist ties: zip ties, plastic security seals, hang tabs. I don’t even know if there is a single category or niche that you could assign to them other than, possibly: stuff.

What I Know About Twist Ties

I know more about twist ties than I used to, but nothing like the learning that is required for industrial clients. I already knew what a twist tie was: a thin wire that’s covered with a flat material and used to tie things together or closed when you don’t need a lot of strength.

I now know that there are a few different varieties of twist ties. Here’s the breakdown:

  • Paper vs Plastic Twist Ties: the covering of the wire on twist ties can be either paper or plastic. The paper covering is possibly a tiny bit cheaper and more eco-friendly. The plastic covering won’t disintegrate when it gets wet, and is less likely to fall apart in general, thus is far more popular.
  • Twist Tie Wire Gauges: the wire in the center of the twist tie can be off different thicknesses. This is a bit surprising to me since no matter what gauge you use they aren’t very strong, so it seems odd that any difference is necessary. They even have dual-wire twist ties that use two wires. My theory is that the benefit of this has more to do with how easy it is to handle rather than the strength of the closure.
  • Twist Tie Colors: obviously they come in a lot of different colors — but not just colors but designs as well. You can have holiday twist ties with snowflakes and snowmen and you can even have premium twist ties that are metallic silver or metallic gold, which allow the twist tie to accent and compliment the packaging design.
  • Spooled Twist Ties: my favorite are the spooled twist ties. Rather than being cut into standard twist tie lengths they come on a massive spool. If you want to you could have a 100-foot twist tie. Or even longer (the spools are over a thousand feet). You could literally twist tie you and your neighbor’s house together.

Believe it or not, this is not all I’ve learned about twist ties — but my time is up for today and I have Christmas shopping to get done yet. For once I’m going to try to avoid being out shopping on the two days before Christmas. Internet, here I come!

Wendy Wu Tours

Like most people, I’ve often spent some time planning imaginary vacations. There are a lot of places in the US that I still want to see, but when we talk about outside of the US, Europe is interestingly low on my list. I want to go visit Africa, Antartica, and of course China. China in particular is filled with about a zillion places I want to visit.

I’m reminded of this when I was looking at the Wendy Wu Tours website, which offers tour packages of China. I was flipping through looking at the different options (but very definitely not looking at the pricing) and trying to decide if I was going to take a Wendy Wu China tour, which one would I want?

Clearly right off the bat we can ignore any of the value (ie: cheaper) options. This is a fantasy vacation after all — I want it all.

Wendy Wu Tour Packages

There are a handful of things that I’d really want to see if I visited China. The Great Wall is on the top of the list. Slightly lower are things like giant pandas (adorable!), the Forbidden City (though I feel it might be a bit touristy), the Terocotta Army, and of course I’d also want to see plenty of little shrines and cool traditional architecture. I don’t really have any interest in the big cities of China, except that they tend to have zoos with giant pandas, and Beijing is near a good section of the Great Wall.

So given that, let’s take a look at what Wendy Wu has to offer:

  • A China Experience: big cities are hit, which is not of interest. But there is the Forbidden City, the Great Wall, and the teracotta army. Also a historic canal town of some kind. Not bad, but I have a hunch it’s too much time spent in modern cities.
  • Glories of China: staying in a small down with rice fields and limestone hills sounds cool and picturesque, but nothing else on my list. This is a clear pass — onto bigger and better things that Wendy Wu has to offer.
  • Majestic Yangtze: two weeks, with a four-night cruise on the Yangtze River — that actually sounds pretty awesome. Also a visit to a famous panda reserve — also awesome. But alas none of the other things on the list.
  • Wonders of China: two weeks and includes the Great Wall, Teracotta army, and giant pandas. Sounds awesome and includes almost everything. I could live without seeing the Forbidden City. But now I kinda want a cruise on the Yangtze…
  • Magnificent China: Oooh, the Grand Buddha in Leshan is included, which sounds cool. Giant pandas included, but nothing else on the list.
  • Grand Tour of China: The Wendy Wu tours site seems a little vague on exactly what’s included in this one. It definitely includes the Great Wall and the teracotta army and also includes the cruise on the Yangtze, but clearly there’s a lot more — does it include the Forbidden City? Giant pandas? Hrmmm… I want to know more darnit.

Stone CNC Machining

At my day job we work with a lot of machining companies: everything from mom & pop job shops that have a couple of 3 axis CNC machines that they use for short runs and prototypes to massive companies with dozens of vertical machining centers and 5 axis CNC machines to the companies that actually build the CNC machines in the first place.

As a result, I have a pretty good layman’s working knowledge of CNC machining — but until recently I always thought of machining as something that you did to metal. I didn’t realized that CNC machining was used for stone as well. Not only can you CNC stone, but stone CNC machining is actually really common for tons of application.

Awesome Stone CNC Machining

Here are some examples of sweet stuff that is made from stone CNC machining. One you start thinking about it you realize that, yes, of course they must use CNC machining to make this stuff. But of course I had never really thought about it before. Or I thought that they used some kind of casting process to manufacture some of these:

Columns and Arches: big marble columns that you see outside of government buildings and universities and fancy places? Stone CNC machining of course. Once upon a time it was a guy with a hammer and chisel, but no more.

  • Birdbaths: concrete ones are probably cast as I thought, but birdbaths from other types of stone are made via stone CNC machining.
  • Sculptures: also CNC machining. Sure your artsy sculptures probably involve a guy with a chisel and a vision, but your garden sculptures are a guy with some CAD software and a stone CNC machine.
  • Bannisters: of course they’re machined. I never really considered that before, since, you know, I don’t have the kind of house that has marble or obsidian bannisters.
  • Shower Stalls: super uber fancy showers with natural stone tile have to have a base with a lip: that curved lip has to be machined by a stone CNC machine.
  • Stone countertops: CNC machining again. Although in my mind it was a guy drawing a line on the granite and with some badass version of a skill saw — though of course that’s pretty ridiculous when you can just punch a button on a keyboard attached to a stone CNC machine and have guarantees perfection every time.

Yeah — and there’s more than just that, but those are some of the big ones that occur to me on the top of my head with the 20 minute blog policy of not looking stuff up and just powering through the blog post. What I’d really like is to get a wee baby CNC machine myself so that I can make little things.

2 Weeks and Going Strong

Just a wee update on quitting smoking. It’s been two weeks now and I’m still going strong. The greatest thing about the electronic cigarette is that is does a pretty good job of substituting for actual smoking. Instead of craving a cigarette, I know typically crave the ecig.

The downside is that I find I’m having to spend a lot of time explaining it to people. Not the fact of what it is — most people have heard of it — but explaining to them that no, it’s not hazardous to their health to get second-hand vapor, no there are no carcinogens. It’s another thing that causes me to lose more faith in the ability of most people to think with logic or rational reasoning.

The thing of it is that it looks like smoke coming out. So even though they know it’s not smoke, there’s an assumption that it’s bad, like smoking is. Let me repeat the salient points there: 1) they know it’s not smoke or tobacco. 2) they still think it’s the same as smoking in terms of hazardous, even though they know it’s not the same thing at all.

My favorite comment that I heard from a friend the other day was, “You don’t know what kind of chemicals are in that.”

In fact, I do. Unlike cigarettes and their hundreds of chemicals, the ecigs have only a few. They have been studied somewhat including the chemical compositions of both the liquid and the vapor. The ingredients have all been very well-studied in the past.

Here’s the rundown:

  • Propylene Glycol: the primary ingredient making up 80% – 99% of the vapor. This is an FDA-approved food additive. It has been used in children’s wards to prevent infection (very successfully in many studies) — though obviously in much larger quantities — there are no health benefits to the miniscule amount of 2nd hand vapor. It’s been noted by some people that propylene glycol is used in antifreeze. This is true — it’s added to make antifreeze less toxic. It’s safe stuff, and has been crazy thouroughly studied.
  • Vegetable Glycerin: used as flavoring in some varieties of liquid, also a food additive.
  • Nicotine: this is the part of tobacco that is mildly addictive, and is a stimulant — similar to caffeine. It is not carcinogenic or bad for you (at least not any worse than drinking soda or coffee). It’s the physically addictive part of cigarettes, but the smoke, tar, and other chemicals are the bad part of smoking.

Custom Sewing – More Things I Understand!

Another client and another service offered by a client that I actually understand — this time it’s custom sewing! Better yet, this client is actually related, somewhat, to the industrial market! I think this may be the first time in my day job that I’ve worked with an industrial client where I could get what they were doing after hearing them describe it in a sentence.

In this case the custom sewing is used to make all kinds of fabric and leather and fake leather bags and coverings. In particular they use the custom sewing to make equipment covers — basically a couple steps up from tossing a tarp over fancy industrial equipment to keep it free from dirt, dust, and the varagies of junk.

The custom sewn covers are a nice thick material that is shaped to cover the specific equipment, and of course usually has a big logo or brand name on it.

I have to say that it’s really nice sometimes to not have to spend time researching what a client does before even getting started working on the account. You hear custom sewing to make equipment covers like lawn mower covers and stuff, and you’re good to go. Now it’s just a matter of working on their marketing strategies.
