Opera Consonance Wax Engine Anti-Skate Modification

Description

This is a 3D-printable anti-skate mechanism upgrade for the Opera Consonance Wax Engine turntable.

The original design uses a thin wire to support the anti-skate weight. While it technically works, in practice it tends to flex and behave inconsistently, which is not exactly what you’d expect from a high-end turntable.

This upgrade replaces the flexible wire with a rigid, dual-pulley system using ball bearings. The result is a much smoother, more stable, and predictable anti-skate behavior.

The vertical pulley ensures proper alignment of the line, while the horizontal pulley carries the load. This eliminates angle-related inconsistencies and prevents the stick-slip behavior often seen with the stock solution.

Features

• Dual-pulley design for proper line guidance

• Ball bearings for near-zero friction

• Rigid structure (no bending or flex)

• Simple, compact design

• Fully 3D printable

Printing

• Material: PLA or PETG

• Standard settings are sufficient

• No supports required

Assembly

• Bearing holes are intentionally undersized

• Drill to 2 mm during assembly

• Ensure bearings rotate freely

🔩 Bearings

This design uses standard miniature ball bearings.

Recommended bearing:

• Inner diameter: 2 mm

• Outer diameter: 5 mm

• Width: 2.5 mm

These are commonly known as MR52ZZ bearings and are widely available.

Shielded (ZZ) bearings are recommended for low friction and basic dust protection.

Shafts:

The bearings are mounted on simple 2 mm shafts.

You can use:

• 2 mm steel rods

• Cut sections of drill bits

• Any straight, rigid 2 mm metal rod

Make sure the shafts fit snugly and keep the bearings properly aligned.

You will need one 22mm long and one 17mm long shaft.

If the shafts fit loosely, they can be glued in place.
Be careful — once glued, they are very difficult to remove, so this should only be done as a final step.

Line choice

Two options were tested:

• Human hair (extremely thin, but difficult to work with 😄)

• Braided fishing line (recommended for consistency and ease of use)

Use the thinnest line available for best results.

If you don't have a special fishing line cutter, then the best way to cut the braided line is using a torch lighter. Normal scissors, knifes will not work!

Notes

This is a simple mechanical fix for a small but noticeable weakness in an otherwise excellent turntable.

If you don’t have a 3D printer, the parts can be ordered from most online printing services.
I had mine printed by Xometry, and the results were perfectly usable.
