4.4.4 Oval fingers, no inserts

4.4.4   measurement

For a bowler who wants an oval finger hole without inserts, Spectre Cloud replaces the round OD field with an OVAL field. There is no auto-suggestion or calculation here — it's a simple text input you annotate yourself.

🔵 The OVAL Field

  • ✅ When you set a finger to oval (no inserts), the round OD field becomes an OVAL text input.
  • ✅ You type the move in thousandths of an inch — for example, 0.030.
  • ✅ That value is a move from the hole size: take the finger's hole size — say 11/16" — and move it 0.030" in one direction to create the oval.
  • ❌ There is no auto-suggestion behind this field — it doesn't calculate anything. It simply records the move you type.

📋 Entering an Oval Finger Hole

  1. Set the finger's round hole size first (e.g. 11/16").
  2. Switch the finger to oval — the OD field becomes the OVAL input.
  3. Type the move in thousandths (e.g. 0.030) for the direction you're cutting.
  4. Repeat for the other finger if needed.

Note: Because nothing is auto-calculated, the value you type is exactly what's recorded. Double-check the amount and the direction before drilling.

Tip: The OVAL field is just a move off the round hole size — note both the round size and the oval move in your records so the fit is reproducible on the next ball.
