Using the oval cut chart to determine cuts manually 5.5.2   oval method   When your Oval Cut Direction is set to NONE, Spectre Cloud does not auto-suggest directional oval measurements. Instead, you determine the correct oval cut size yourself using the ova...

When NONE mode is preferable (experienced fitters, custom setups) 5.5.3   oval method   Spectre Cloud's Oval Cut Direction = NONE mode is not just a fallback for shops without directional drill presses — it is also the preferred working mode for many experi...

EDGE method explained — how pitch is placed at edge of oval 5.6.1   pitch   The EDGE method is one of the core calculation approaches available in Spectre Cloud's Oval Calculator. It determines where pitch is applied relative to the oval cut by placing the ...

CENTER method explained — how pitch is placed at center of oval 5.6.2   pitch   The CENTER method is the second oval calculation approach available in Spectre Cloud's Oval Calculator. Where the EDGE method anchors pitch to the leading edge of the oval cut, ...

EDGE with and without Add Pitch Thumb — comparison 5.6.3   pitch   When using the EDGE method in Spectre Cloud's Oval Calculator, a secondary option becomes relevant: Add Pitch Thumb. This setting controls whether the thumb hole's pitch is factored into the...

CENTER with and without Add Pitch Thumb — comparison 5.6.4   pitch   Just as the EDGE method can be run with or without the Add Pitch Thumb option, the CENTER method offers the same choice. The underlying question is identical — should the thumb's pitch val...

Choosing EDGE vs. CENTER: which method fits which bowler? 5.6.5   TIP   guide   With four calculation configurations available in Spectre Cloud's Oval Calculator — EDGE and CENTER, each with or without Add Pitch Thumb — the practical question every operator...

1° vs. 5° Oval Degree increments and their precision impact 5.6.6   pitch   When Spectre Cloud calculates oval cuts, one of the underlying settings controls how finely the oval angle is expressed: the Oval Degree increment. This setting determines whether o...

Using "Flip V/H on oval cuts" to match your machine's axis 5.7.1   calibration   When Spectre Cloud outputs oval cut directions, it displays them relative to a default axis orientation. Depending on how your drill press is set up — and how you physically or...

Worked example: how flipping V/H changes the output numbers 5.7.2   example   The previous page explained what the Flip V/H on Oval Cuts setting does conceptually — it swaps the Vertical and Horizontal axis labels on oval cut outputs to match your drill pre...
