Death Racer Weapon (bludgeon) Rod Jig

This jig is designed to securely hold a carbon fiber rod in place for precise drilling using a drill press. It ensures the holes are aligned accurately, making it a straightforward replacement part for anyone who has broken theirs.

The jig was printed in PLA using 6 walls and 20% gyroid infill. That is probably overkill, but this is a clamping tool, so the extra strength helps.

I reamed all holes in the top clamp with a 3 mm reamer, but a 3 mm or 1/8" drill bit will also work.

Heat set inserts were installed from the bottom for additional strength.

Insert the bare rod into the jig and secure it using the eight M3x20 mm screws. Washers are optional, but I used them to help spread the clamping load. Slowly tighten the screws in a crisscross pattern to avoid binding.

Use a drill press with a sharp 1/8" drill bit at around 3000 RPM. With the drill press off, align the holes in the jig with the drill bit first. Then start the drill press and drill using light, consistent pressure while letting the drill do the work.

USE A MASK AND/OR DUST COLLECTION. Carbon fiber dust is not something you want to inhale.
