Whether the fabricator’s store is large or small, the Ironworker is the backbone. The Ironworker isn’t a single machine; it is five machines united into an engineering wonder. It has much more versatility than most people would imagine. The five working sections that are involved in the make-up of this machine are a punch, a section shear, a bar shear, a plate shear, and a coper-notcher.

A number of the cheaper ironworkers are constructed to employ a fulcrum where the ram shakes back and forth, making the punch go into the succumb at a small angle. This normally leads to the eroding of the punch and die on the front rims. The higher quality machines integrate a ram which moves in a direct vertical line and utilizes modifiable gibs and guidebooks to ensure a constant traveling route.

Today, we’re announcing Dart 2, a reboot of the language to embrace our vision of Dart: as a language uniquely optimized for client-side development for web and mobile.

With Dart 2, we’ve dramatically strengthened and streamlined the type system, cleaned up the syntax, and rebuilt much of the developer tool chain from the ground up to make mobile and web development more enjoyable and productive. Dart 2 also incorporates lessons learned from early adopters of the language including Flutter, AdWords, and AdSense, as well as thousands of improvements big and small in response to customer feedback.

Dart’s Core Tenets

Before we talk more about the advances in Dart 2, it’s worth identifying why we believe Dart is well positioned for the needs of client-side developers.

In addition to the attributes necessary for a modern, general purpose language, client-side development benefits from a language that is:

  • Productive. Syntax must be clear and concise, tooling simple, and dev cycles near-instant and on-device.
  • Fast. Runtime performance and startup must be great and predictable even on small mobile devices.
  • Portable. Client developers have to think about three platforms today: iOS, Android, and Web. The language needs to work well on all of them.
  • Approachable. The language can’t stray too far from the familiar if it wishes to be relevant for millions of developers.
  • Reactive. A reactive style of programming should be supported by the language.

Dart has been used to ship many high-quality, mission-critical applications on the web, iOS, and Android at Google and elsewhere and is a great fit for mobile and web development:

  • Dart increases developer velocity because it has a clear, succinct syntax and is able to run on a VM with a JIT compiler. The latter allows for stateful hot reload during mobile development, resulting in super fast dev cycles, where you can edit code, compile and replace in the running app on the device.
  • With its ability to efficiently compile to native code ahead of time, Dart provides predictable, high performance and fast startup on mobile devices.
  • Dart supports compilation to native code (ARM, x86, etc.) for fast mobile performance as well as transpilation to efficient JavaScript for the web.
  • Dart is approachable to many existing developers, thanks to its unsurprising object-oriented aspects and syntax that — according to our users— allows any C++, C#, Objective-C, or Java developer to be productive in a matter of days.
  • Dart works well for reactive programming with its battle-hardened core libraries, including streams and futures; it also has great support for managing short-lived objects through its fast generational garbage collector.

Dart 2: Better Client-Side Development

In Dart 2, we’ve taken further steps to solidify Dart as a great language for client-side development. In particular, we’ve added several new features including strong typing and improving how UI is defined as code.

Strong, Sound Typing

The teams behind AdWords and AdSense have built some of Google’s largest and most advanced web apps with Dart to manage the ads that are bringing in a large share of Google’s revenue. From working closely with these teams, we identified a big opportunity to strengthen Dart’s type system. This helps Dart developers catch bugs earlier in the development process, better scale to apps built by large teams, and increase overall code quality.

This isn’t unique, of course. In the broader web ecosystem, there’s also a growing trend towards adding type annotations to JavaScript. For example, TypeScript and Flow both extend JavaScript with type annotations and inference to improve the ability to analyze code.

In the small example below, Dart 2’s type inference helps uncover a somewhat subtle error and as result, helps improve overall code quality.

What does this code do? You could reasonably expect that it would print ‘27’. But without Dart 2’s sound type system enabled it prints ‘10000’, because that happens to be the least element in the list of strings when ordered lexicographically. With Dart 2, however, this code will give a type error.

UI as Code

When creating UI, having to switch between a separate UI markup language and the programming language that you’re writing your app in often leads to frustration. We’re striving to make the definition of UI as code a delightful experience to dramatically reduce the need for this context switching. Dart 2 introduces optional new and const. This much-requested feature is very valuable on its own, and also sets the direction for other things to come. For example, with optional new and const we can clean up the definition of a UI widget so that it doesn’t use a single keyword.

Client-Side Uses of Dart

Mobile

One of the most significant uses of Dart is for Flutter, Google’s new mobile UI framework to craft high-quality native interfaces for iOS and Android. The official app for the hugely popular show Hamilton: The Musical is an example of what Flutter is enabling developers to build in record time. Flutter uses a reactive programming style and controls the entire UI pixel by pixel. For Flutter, Dart fits the bill in terms of ease of learning, reactive programming, great developer velocity, and a high-performance runtime system with a fast garbage collector.

Web

Dart is a proven platform for mission-critical web applications. It has web-specific libraries like dart:html along with a full Dart-based web framework. Teams using Dart for web development have been thrilled with the improvements in developer velocity. As Manish Gupta, VP of Engineering for Google AdWords, explains:

The AdWords front-end is large and complex, and is critical to the majority of Google’s revenue.We picked Dart because of the great combination of perf and predictability, ease of learning, a sound type system, and web and mobile support.Our engineers are two to three times more productive than before, and we’re delighted we switched.

Moving Forward

With Flutter and Dart, developers finally have the opportunity to write production-quality apps for Android, iOS, and the web with no compromises, using a shared codebase. As a result, team members can fluidly move between platforms and help each other with, e.g., code reviews. So far, we have seen teams like AdWords Express and AppTree share between 50% and 70% of their code across mobile and web.

Dart is an open source project and an open ECMA standard. We welcome contributions to both the Dart core project and the ever growing ecosystem of packages for Dart.

You can try out Dart 2 in Flutter and the Dart SDK from the command line. For the Dart SDK, get the latest Dart 2 pre-release from the dev channel and make sure to run your code with the --preview-dart-2 flag. We also invite you to join our community on gitter.

With the improvements announced today, Dart 2 is a productive, clean, battle-tested language that addresses the challenges of modern app development. It’s already loved by some of the most demanding developers on the planet, and we hope you’ll love it too.

Obviously enough, one of the first things many people want to know when getting started with scrolling as a hobby is what saw to buy. Whether you are looking to purchase your first scroll saw, or you are looking to upgrade to a better one, there are many things to consider. In this article I will attempt to touch on all aspects so that you are able to make an informed decision. I will also make some recommendations based on personal experience and what I feel is the general consensus of the scroll sawyers I have discussed the matter with.

Important Considerations

Blade Changing and Blade Holders: The saw should accept standard 5" pinless blades. A lot of scrollwork simply cannot be done with a saw that requires pinned blades. While pinned blades have some advantages, they have one very big disadvantage: You can't cut any small inside detail cuts since you have to drill a very big hole to get the blade's pin through.

Also, how easy is it to change a blade? Is a tool required for this? Some scroll saw projects have hundreds of holes. This means you have to remove one end of the blade from the holder and thread it through the wood and re-mount it in the holder more times than you can count. Be sure the process is comfortable and relatively easy to do. A saw in which the arm can be raised and which holds itself in this position is most desirable as it makes this process much easier as do tool-less blade holders.

Variable speed: A great many saws offer variable speed and you should not have a problem finding this feature in any price range. Sometimes you will want to slow the blade down just to cut slower, other times you must slow it down to prevent the blade from burning the edges of the wood as you cut. Some scroll saws require belt changing to change speeds. Personally, I would highly recommend a saw an electronic speed control.

Vibration: Vibration is very distracting when cutting and must be kept to a bare minimum. Some saws inherently vibrate more by design. This feature tends to be very much dependent on the cost of the particular saw. Vibration can be reduced by mounting the saw to a stand. A sturdily mounted saw and heavier saw/stand combination will reduce vibration. Many companies offer stands purpose built for their saws.

Size Specifications: Manufacturers often list the maximum cutting thickness of their saws. Since this is always more than 2", you can ignore this as you likely will never want to cut anything thicker than that on a scroll saw.

The depth of the throat however is something you may want to consider if you think you will be cutting very large projects. A small throat will limit how big of a piece you can swing around on the table while you cut. For many this is not a very big deal since it is somewhat difficult and unpleasant to swing around a big piece of wood on a scroll saw. This limit can also be circumvented by the use of spiral blades which don't require the work to be rotated at all.

A most notable difference between the Excalibur and other saws is that the head of the saw tilts rather than the table. This is a nice advantage if you intend to do a lot of angled cutting. The one feature that I personally am leery about is that you only have a quick release for the tension at the front of the saw's upper arm and the fine adjustment is at the back of the arm. This is a relatively recent change to the saw however I have not seen any negative feedback about this setup. Theoretically, once you have set the fine adjustment, you don't have to adjust it very often and you just need the quick release when undoing/redoing the blade to feed it through your project.

These saws are manufactured by General International, which has a reputation for quality.

Other notable mentions RBI and Eclipse both offer high end saws with great performance and low vibration. You may want to check these saws out if you can afford them. Since they are out of most people's price range, I have not heard a whole lot of feedback on them. In my opinion, many of these models do however have inconveniently located controls and/or require tools for blade changes which do give me cause for concern.

Hegner offers four different models starting at about $700 and going all the way to $2400. The lowest end model "Multimax 14-E" is only single speed which I would definitely stay away from. In my opinion there are several better choices for a comparable or cheaper price. The $2400 industrial "Polymax" model requires belt changing to change the speed which is an inconvenience. Because of this issue and the high price tag, I would only consider this model for a truly industrial purpose. This leaves us with the Mutimax 18-V and 22-V models to consider.

All Hegner saws require tools for blade changes. This fact, in addition to what I would personally consider an inconvenient control layout would make me think twice about a Hegner. That being said, most people who own Hegners are very happy with the quality and usability of their saws. Since I have not personally used one, I will leave this matter for your further consideration if you can afford a saw in this price range.

Conclusion

I hope this article has provided you with enough information to allow you to make the best possible investment of your money so that you can start with or upgrade to a scroll saw that will provide you years of scrolling pleasure.
