Using the Grizzly Industrial Parallel Sets in the Real World
For any serious machinist or workshop hobbyist, the quest for precision is an ongoing one. When setting up workpieces on a milling machine or a drill press, achieving perfectly parallel surfaces is fundamental. This is where a reliable set of parallels becomes indispensable, and I recently had the opportunity to thoroughly evaluate the Grizzly Industrial Parallel Sets. My work often involves intricate setups in both my home workshop and occasional freelance projects in professional settings, and I was looking for a sturdy, consistent set to complement my existing tooling. I’d been experiencing some minor inconsistencies with my older, mismatched parallels, leading to frustrating adjustments and less-than-ideal finishes.
My initial impression upon receiving the Grizzly Industrial Parallel Sets was one of solid, no-nonsense craftsmanship. The wavy steel construction felt robust, and the inclusion of a protective case immediately signaled a thoughtful approach to product packaging and longevity. I had considered a few other brands, some significantly more expensive, but the combination of Grizzly’s reputation for industrial-grade tools and the accessible price point made this set an appealing choice. My first reaction was a quiet sense of satisfaction, knowing I now had a tool that looked and felt like it was built to perform.
Real-World Testing: Putting Grizzly Industrial Parallel Sets to the Test
First Use Experience
My first use of these parallels was on my Bridgeport milling machine, setting up a small block of aluminum for a series of precise cuts. The parallels slid easily under the workpiece, providing a stable and level base without any noticeable wobble. I tested them in varying light conditions on my workshop bench, and the consistent thickness made adjustments straightforward. There were no immediate issues or surprises; they simply performed as expected, providing a firm and reliable support.
Extended Use & Reliability
After several weeks of consistent use, involving multiple setups for milling, drilling, and even some light grinding operations, the Grizzly Industrial Parallel Sets have held up remarkably well. I’ve subjected them to the usual workshop grime and the occasional accidental contact with a dropped tool – which they survived without any significant damage, though some minor surface scuffs are now visible. Their durability is impressive; the wavy steel design seems to distribute stress effectively, and I haven’t noticed any warping or loss of parallelism. Cleaning is straightforward; a quick wipe down with a solvent and a light oiling after each use keeps them in prime condition and prevents rust. Compared to some cheaper alternatives I’ve used in the past that developed play or bent easily, these industrial parallels are a significant upgrade in terms of longevity and consistent performance.
Breaking Down the Features of Grizzly Industrial Parallel Sets
Specifications
The Grizzly Industrial Parallel Sets are constructed from wavy 1/8″ thick steel, ensuring a rigid yet precise foundation for your workpieces. Each set contains matched pairs that measure 4-1/2″ long, with available widths ranging from 1/2″ to 1-1/2″ in 1/8″ increments. This thoughtful selection of sizes allows for a wide range of clamping scenarios and workpiece heights. The inclusion of a protective case is a crucial detail, safeguarding these precision tools from damage when not in use and preventing them from getting lost among other workshop accessories. The manufacturer is, of course, Grizzly Industrial, a name synonymous with robust workshop equipment.
These specifications translate directly into practical benefits. The consistent 1/8″ thickness across all parallels means you can stack them or use them individually with predictable results, crucial for achieving exact measurements. The 4-1/2″ length offers a good balance for most benchtop machining tasks, providing ample support without becoming unwieldy. The range of widths ensures you can accommodate various material thicknesses and clamping setups, making these parallels a versatile addition to any machinist’s toolkit.
Performance & Functionality
In terms of their primary job – providing a stable, parallel surface for holding workpieces – the Grizzly Industrial Parallel Sets excel. Their main strength lies in their consistent parallelism and rigidity, which are critical for achieving accurate machining operations. When setting up a piece, they offer a solid platform that inspires confidence, minimizing guesswork and reducing the likelihood of errors caused by uneven support. A minor point for consideration is that while the wavy design adds rigidity, it means they aren’t perfectly flat across their entire width like some ultra-high-precision, solid parallels. However, for the vast majority of workshop applications, this slight variation is negligible and outweighed by their durability and cost-effectiveness.
Design & Ergonomics
The design of these parallels is utilitarian and robust, befitting their industrial designation. The wavy steel construction isn’t just for aesthetics; it provides increased strength and stiffness compared to solid parallels of the same thickness, helping to resist bending under clamping pressure. The overall feel is one of solidity; they possess a reassuring heft that speaks to their material quality and manufacturing process. Their ergonomics are straightforward – they are simply blocks to be placed under workpieces. The 4-1/2″ length is comfortable to handle and position, and the varied widths make them easy to grip and manipulate when setting up. The finish is a functional, utilitarian coating that, while not luxurious, is practical for a workshop environment.
Durability & Maintenance
Given their 1/8″ thick steel construction, these parallels are built for the long haul. Under normal workshop conditions, I anticipate them lasting for many years, potentially a lifetime. The wavy design is inherently more resistant to bending than solid parallels of equivalent thickness, offering good resilience against accidental impacts or excessive clamping forces. Maintenance is minimal; a light wipe with a rag and a bit of oil after use is sufficient to prevent corrosion, especially if your workshop has any humidity. The only real point of caution would be to avoid dropping them on very hard surfaces, as any precision tool can be damaged by a severe impact, but their inherent toughness offers a good margin of safety.
Accessories and Customization Options
The Grizzly Industrial Parallel Sets come with one essential accessory: a protective case. This is a significant plus, as it keeps the parallels organized and prevents them from becoming nicked or scratched, which could compromise their precision. There are no direct customization options for the parallels themselves, as they are sold as matched sets with fixed dimensions. However, their primary function is to support workpieces, so their “customization” comes into play through how they are used in conjunction with various workholding devices like clamps, vises, and hold-downs. The protective case is well-designed and holds each pair securely, preventing them from shifting around.
