30 mm Guide Pin

The 30 mm Guide Pin is a removable positioning component designed for the Broinwood CNC Spoilboard System.

It installs directly into the spoilboard grid and can be used as a stop, fence, or reference point for positioning workpieces.

Its lower 30 mm height provides a more compact option when the additional height of the 40 mm Guide Pin is not needed.

The outside surface is intentionally textured to provide additional grip inside the MDF pocket and against the edge of the workpiece.

How to Use

1. Insert the 30 mm Guide Pin into any available pocket in the spoilboard grid.
2. Position additional Guide Pins as needed to create stops, fences, or reference points for the workpiece.
3. Position the workpiece against the Guide Pins and secure it using the appropriate workholding method.
4. When the setup changes, remove the Guide Pin and reposition it in another pocket.

The Guide Pin should fit snugly without excessive play, while still being possible to insert and remove by hand.

Easy Removal

The 30 mm Guide Pin has a side through-hole designed only for removal.

If the Guide Pin is seated tightly in the MDF pocket, insert an Allen wrench, screwdriver, or another suitable tool through the side hole and use it to pull the Guide Pin upward.

The side hole is not designed to accept a Threaded Insert.

Important

Because of its intentionally textured outer surface, the 30 mm Guide Pin does not have one constant outside diameter.

Depending on where the measurement is taken across the textured profile, the outside diameter can range from approximately 25.01 mm to 25.35 mm.

For this reason, determine the correct pocket size by actual fit rather than by measuring the outside diameter of the Guide Pin.

Before machining the complete spoilboard grid, I recommend starting with a 25.0 mm test pocket. If the pocket is too tight, increase the diameter gradually in 0.1 mm increments until the correct fit is achieved.

In most setups, the final pocket diameter will be around 25.3 mm, but a slightly larger pocket is acceptable if needed.

The Guide Pin should fit snugly without excessive play while still being possible to insert and remove by hand.

The correct fit is more important than the exact pocket diameter.
