Modifying Randal Baseplates: Redrilling for New School Mounting

Many longboarders, especially those who enjoy downhill or freeride, often tweak their setups to achieve the perfect balance of stability and responsiveness. One such modification involves using a lower-degree baseplate on the rear truck to enhance stability. This article explores the process of redrilling a Randal 28° Comp II baseplate to accommodate new school mounting patterns, a common need for riders using modern longboard decks.

Why Use a 28-Degree Baseplate?

For riders aiming for a softer, more fluid feel with their longboard, a lower-degree baseplate at the rear can be a game-changer. A symmetrical setup with soft bushings can be prone to speed wobbles, especially on rough terrain. By employing a lower degree baseplate in the back, you can achieve enhanced stability while maintaining a soft and responsive ride.

Caliber trucks are compatible with Randal baseplates, making it possible to swap to the Randal 28° Comp II plate. While 35-degree plates are available, some riders find them too responsive, especially when used with softer bushings. This is where the 28-degree plate shines, offering a stable, yet still lean-able setup. Although personal preferences may vary, with some now preferring the 35°, the 28-degree baseplate is an excellent starting point for those seeking increased stability. This can be achieved through using Randal plates and redrilling them, as described below. Alternatively, tall bushings can also help in achieving a similar result of having hard bushings but still getting plenty of lean.

Step-by-Step Guide to Redrilling Your Baseplate

The Randal Comp II luge baseplate comes with old-school mounting holes, which may not fit modern longboard decks that predominantly use new school mounting patterns. To address this, you’ll need to redrill the baseplate. The following is the process used:

First, secure the Comp II baseplate onto a 35-degree baseplate using screws. This ensures the new school holes are accurately aligned on the baseplate you want to modify.

Next, begin drilling with a small drill bit to break the surface of the baseplate and confirm the accuracy of your measurements. Once you’re confident with the initial holes, use a larger drill bit to expand them. This step-by-step approach is key to avoiding any misalignments. Note that accuracy is critical. If the holes are misaligned, the truck may sit diagonally instead of straight, impacting your ride.

Challenges and Solutions

While the redrilling process is straightforward, there are a couple of potential challenges you need to be aware of. The newly drilled hole on the left side will only fit a nut if it’s placed upside down because the structural support gets in the way. Additionally, holes on the right side may not provide enough clearance for a skate tool to tighten the nut properly, since the pivot may block the tool. However, it is still possible to tighten the nut, even if the tool’s movements are limited.

The Benefits of a Modified Baseplate

Despite minor challenges, the outcome of a redrilled baseplate is well worth the effort. This modification allows you to enjoy a more stable downhill setup without compromising the ability to lean. The author of the original article uses a setup with 44° 85a/85a bushings up front and 28° 93a/90a bushings in the back, which fits perfectly with the existing Randal pivot cup. This setup provides plenty of lean while ensuring stability. The modification is a cost-effective way to achieve a lower angle truck at the back, and an improved feel.

Final Thoughts

Modifying your longboard setup, like redrilling a baseplate, can significantly enhance your riding experience. By taking your time, and being meticulous with your work, you can avoid costly errors. If you are looking for a lower angle truck at the rear, a redrilled Randal baseplate is a great and affordable option. The modification allows for a stable, yet leanable setup, that is perfect for downhill and freeride.
