Frontier Sawmills – OS27 Review

Exactly one year ago, I embarked on a milling journey with the Frontier Sawmills OS27, a rugged and reliable mid-sized mill. It’s been a year of significant testing and utilization, and I’m here to share a detailed review based on real-life usage.

Upon receiving the Frontier OS27, its robust and clean design was immediately apparent, reflecting its quality construction. The assembly process, while taking around 6-7 hours, was a test of patience due to a manual that was not as clear as one might hope. However, the overall setup was intuitive enough, especially for those familiar with mechanical assembly. The mill is equipped with a powerful 13.5hp Briggs & Stratton engine, available in both recoil and electric start options, enhancing its reliability and efficiency. This sawmill impressively handles logs up to 27 inches in diameter and can produce boards up to 11 feet long, making it a versatile tool for a variety of milling tasks.

Performance and Usability

Over the past year, the Frontier OS27 has demonstrated its capability to handle a variety of wood types, proving to be an invaluable tool in my milling operations. The sawmill’s rigid 4-post saw carriage design plays a crucial role in its performance, significantly reducing saw head bounce, sag, and sway during cuts. This stability is crucial for achieving smooth, straight cuts and has consistently resulted in high-quality lumber.

Additionally, the adjustable blade guide is a standout feature that greatly aids in maintaining the precision of the blade’s path, especially when making narrower cuts. This adaptability ensures the blade is well-supported regardless of the material width, which not only improves the cut quality but also extends the life of the blade by reducing wear and tear.

The log dogging system further enhances the mill’s usability by securely holding the logs during the cutting process. This system prevents the logs from shifting, providing a reliable stability that is necessary for consistent, accurate milling. The combination of these features makes the OS27 not just functional but also user-friendly, even for those who may be new to sawmilling or are operating the mill as a one-person operation.

Mobility and Customization

The addition of the optional Mobility Towing Kit to the Frontier OS27 has significantly enhanced its portability, allowing me to easily transport the mill to various locations. This kit, which includes a subframe, axle, 12-inch wheels, removable drawbar, and support jacks, provides a robust solution for moving the sawmill across different terrains. The mobility kit not only simplifies the transport of the mill but also ensures it can be quickly set up and stabilized at each new location, thanks to the adjustable support jacks and the carriage lockdown system.

This feature is particularly beneficial for custom milling operations or when working in remote areas, as it allows the sawmill to be brought directly to where the logs are located, reducing the need for additional log transportation. The ease of mobility and the ability to customize the setup based on the specific requirements of each site make the OS27 a versatile and indispensable tool for both personal and professional wood milling projects.

Maintenance and Support

Maintaining the Frontier OS27 has been quite manageable, thanks to the availability of essential parts like bearings and belts at local stores, which makes regular upkeep less of a hassle. This accessibility ensures that I can keep the sawmill in top working condition without significant downtime.

My experience with customer service has been overwhelmingly positive, highlighted by timely responses and helpful support. Effective communication from the customer service team has made it easier to address any issues promptly and keep the mill running efficiently. This level of support is reassuring, particularly when tackling more extensive projects or when specific problems arise that require professional guidance.

Personal Reflections

After a year of operating the Frontier OS27, I’ve gained a deep appreciation for its robust functionality and reliability, despite recognizing areas for potential improvement. The durability of the powder coating and the clarity of the manual were initially concerning; however, these issues pale in comparison to the mill’s overall performance.

By making a few adjustments and custom modifications, I’ve tailored the OS27 to better meet my specific needs, enhancing its efficiency and effectiveness. This experience has solidified my confidence in the mill as a vital tool in my woodworking and milling endeavors, proving its worth in various challenging projects.

When comparing the Frontier OS27 with the Wood-Mizer LT15 and the Norwood LumberMate LM29, several key aspects stand out:

• Engine and Power: The OS27’s engine is robust for its size, matching closely with the LumberMate LM29 and slightly less powerful than the LT15, which offers up to 19 HP. The choice between recoil and electric start on the OS27 provides versatility depending on user preference.
• Capacity and Build: All three mills handle large log diameters, but the Wood-Mizer LT15 can handle slightly wider cuts due to its larger frame. The OS27 and LM29 are more similar in capacity, both offering up to 29 inches in log diameter.
• Ease of Use and Assembly: The OS27 is noted for its easy assembly and straightforward manual, making it a good option for less experienced users. In contrast, the LT15 might require more setup and is a bit less intuitive without prior experience.
• Mobility and Adaptability: All models offer mobility kits, making them suitable for users who need to move their sawmill between locations. The OS27’s kit is noted for being particularly robust.
• Price and Value: The OS27 typically comes in at a lower price point, offering significant value, especially with its patented features like the EZ Blade Tension and auto-locking sawhead. The LT15 and LM29 can become more expensive with added features and upgrades.

Overall, the Frontier OS27 offers strong competition in the mid-sized sawmill market with its combination of price, features, and ease of use, making it a suitable choice for both beginners and more experienced millers. The choice between these models will depend on specific needs such as cut size, engine power, and budget.
