Using a straight guide with your Makita router can be tricky if you’re not familiar with the nuances. While bearing guides might seem outdated, understanding how to properly use them, especially with a Makita router, is a valuable skill. Let’s dive into how to effectively use a Makita router straight guide, addressing common issues and exploring alternative methods.
The primary thing to keep in mind is that the router bit’s diameter must be smaller than the bearing’s outer diameter. Failing to adhere to this simple rule will lead to the router bit cutting into the guide itself, causing damage and inaccurate cuts. This is a common pitfall, so always double-check compatibility before starting.
Adjustment is also crucial. When viewed from below, the outer edge of the bearing should almost entirely cover the router bit, leaving only a small amount exposed for the cut. This exposed portion determines the width of your cut. Achieving this precision can require careful adjustment and fine-tuning. If you need to make multiple passes, this fine-tuning becomes even more critical and time-consuming.

However, it’s true that many woodworkers now prefer router bits with top or bottom bearings. These bits follow the edge of the workpiece directly, often simplifying the process and providing more consistent results. So, when does a straight guide still make sense?
One scenario where a Makita router straight guide proves useful is cutting a rebate (rabbet) along the length of a curved board using a straight bit. While a rabbeting bit would likely be the easier choice in most situations, the straight guide can provide control and stability when working with curves.

Alternatives to the straight guide also exist, offering varying degrees of precision and ease of use. Some routers, particularly older models, might include two-point adapters that bolt onto the router base. These adapters provide two points of contact with the board edge, one on either side of the bit, for increased stability. While not universally adopted, these adapters demonstrate the ongoing effort to improve edge-following techniques.
Ultimately, mastering the Makita router straight guide involves understanding its limitations, recognizing its specific applications, and knowing when alternative methods might be more appropriate. Pay attention to bit diameter, precise adjustments, and the specific demands of your project to achieve the best results. By carefully considering these factors, you can make informed decisions about how to achieve accurate and efficient routing.
