A Plane Crazy gear calculator is a community web tool designed to calculate the precise angle lock degrees and compressor offsets needed to build custom-toothed gears in Plane Crazy on Roblox. By entering your desired tooth count and block spacing into the tool, you get the exact half angle, full angle, and offset coordinates required to arrange rod cylinders in a functional circle without manual trigonometry.

Required Blocks for Custom Gear Assembly

According to player demonstrations, building a functional small gear using calculated angles requires a specific sequence of structural and mechanical components:

  • Anchor Block: Placed high off the ground to prevent the rotating gear mechanism from colliding with the terrain.
  • Motor: Can be set to powered or unpowered depending on whether the gear serves as a drive gear or a free-spinning follower.
  • Compressor: Mounted directly in front of the motor to provide offset adjustments.
  • Angle Locks: Placed atop the compressor to orient the gear teeth radially.
  • Rod Cylinders: Attached beside the angle locks to act as individual gear teeth.

Step-by-Step Guide to Using the Gear Calculator

To create a gear using the calculator workflow, place your base assembly and input your target tooth count into the calculator tool:

  1. Position the base: Place an anchor block elevated in your build plot, attach a motor to it, and attach a compressor in front of the motor. Set the compressor value to "all".
  2. Align the first angle lock: Place an angle lock on top of the compressor, ensuring the yellow directional light faces downward.
  3. Stack the angle blocks: Place additional angle locks corresponding to the number of teeth you intend to make (for example, seven blocks for a seven-tooth gear).
  4. Attach teeth: Place rod cylinders directly next to each angle lock.
  5. Calculate the angles: Open the gear calculator tool. In the first field, input the total number of teeth (such as 7) and select calculate angles.
  6. Set the first angle lock: Copy the half angle value from the calculator. Paste this number into the very first angle lock. Disable collisions and enable transparency on this block.
  7. Set the remaining angle locks: Copy the full angle value from the calculator. Paste this figure into all the remaining angle locks. Disable collisions and enable transparency across all of them.

Centering the Gear with Compressor Offsets

If a newly constructed gear rotates unevenly or sits off-center, the calculator's offset feature corrects the alignment:

  1. Measure the block distance from the compressor to the angle lock (a standard compact assembly uses a distance of 1).
  2. Input this distance number into the offset section of the gear calculator and run the calculation.
  3. Copy the resulting offset value.
  4. Open the compressor placed behind your angle lock assembly and paste the value into its settings.
  5. Turn off collisions and turn on transparency on the compressor to ensure smooth rotation during operation.

Building Gears with Over 12 Teeth

Gears scaled beyond standard compact sizes have specific clearance requirements:

  • Height clearance rule: Any gear designed with more than 12 teeth must be offset by at least one block higher (or more) in order to align and mesh properly.
  • Tooth spacing: Stacking higher tooth counts requires adjusting angle increments accordingly in the calculator to avoid tooth overlapping.

Mechanical Calculations in Plane Crazy Builds

Custom gears and rod-cylinder assemblies form the foundation of complex mechanical systems in Plane Crazy. In demonstrated player builds, gear-driven mechanisms have been used to power physical calculators, such as a mechanical Leibniz wheel:

  • Stepped teeth: A rotating cylinder assembly equipped with nine rods of varying lengths represents digits 1 through 9.
  • Sliding input gear: Moving a gear along a drive shaft changes how many teeth it contacts per turn, rotating a result dial by an exact number of increments.
  • Carry mechanisms: Passing from 9 to 0 can trigger secondary hover thrusters or trail block sensors to push carry gears forward by one position.
  • Reset sequences: Secondary gears built with a missing tenth tooth at position zero allow continuous drive gears to slip, automatically stopping all display columns at zero.

Frequently Asked Questions

Does the gear motor need to be powered?

No. In testing, the base motor can be set to powered or unpowered depending on whether you want a motorized drive gear or a passive gear driven by an adjacent mechanism.

Which way should the angle lock face?

The angle lock placed directly on top of the compressor must have its yellow light facing downward to correctly align the rotational axis.

Why do angle locks need transparency and collisions turned off?

Disabling collisions prevents the overlapping angle blocks and compressor from physically jamming against each other, while transparency hides the interior mechanical stack so only the rod teeth remain visible.
