2.3.2 Initial pitch inside the total oval — Edge vs. Center & Pitch Included Yes/No
2.3.2 oval When drilling an oval hole, Spectre Cloud needs a reference point from which to calculate the initial pitch of that hole. Because an oval opening has width — unlike a round hole, which has a single center point — there are two valid ways to defin...
2.3.6 Flip V/H on oval cuts — matching your drill press DRO display order
2.3.6 oval The Flip V/H on oval cuts setting controls the display order of the vertical and horizontal values in the oval cut cards shown by the Spectre Cloud oval calculator. This setting should match the order your drill press digital readout (DRO) displa...
2.3.3 Oval Width Calculator — Bit Size, Decimal, or Difference input method
2.3.3 oval When calculating an oval thumb hole, Spectre Cloud needs to know the oval width — the final size of the opening the bowler's thumb will sit in. This setting controls how you input that measurement. There are three options: Oval Width (Bit Size), ...
2.3.5 Oval Cut 'Move' Direction — V/H, H only, V only, or None
2.3.5 oval The Oval Cut Move Direction setting controls which directional components Spectre Cloud calculates and displays when outputting oval cut values. Depending on your drill press type and how you cut ovals, you may work with both vertical and horizon...

4.6.1 Selecting an oval thumb: starting bit, oval width, oval degree, and taper
4.6.1 oval An oval thumb hole needs four inputs beyond the standard thumb measurements. Together they define the shape, orientation, and profile of the finished oval so Spectre Cloud can generate the drilling sequence. The calculation mechanics live in the ...
4.6.2 Entering the oval inputs (step-by-step)
4.6.2 oval This page is the step-by-step companion to 4.6.1. The four oval inputs — starting bit, oval width, oval degree, and taper — are defined in 4.6.1, and the calculation that turns them into drilling movements is covered in 4.6.3 and the Oval Calcula...
4.6.3 How the system calculates the oval cut from your inputs
4.6.3 oval Once the four oval inputs are entered, Spectre Cloud calculates the drilling instructions — a set of x-axis and y-axis offset movements that tell you how to reposition the ball relative to the bit to open the round pilot hole into the correct ova...
