4.1.6   concept When drilling finger holes for bowlers who use inserts, the drill bit must match the insert's Outside Diameter (OD) — the outer dimension that sets the hole size. Spectre Cloud sizes these holes for you through Autofill Insert OD (2.6.6). This...

4.2.2   step-by-step When you create a new spec sheet, Spectre Cloud lets you give it a plain-English name at the top of the sheet. This name is how you identify the sheet later — a far more useful label than relying on the created and modified dates alone. ...

4.2.4   step-by-step Before entering span and pitch measurements, you need to identify which grip type the bowler uses. The grip type determines how the fingers sit in the ball and which measurements are relevant. Most fitting sheets — handwritten, printed, o...

4.2.5   TIP   step-by-step When you need to make an adjustment to an existing fit, and you want to document the change in the spec sheet history, cloning a spec sheet saves time and prevents transcription errors. Instead of re-entering every measurement from ...

4.2.6   TIP   step-by-step Once a spec sheet is complete, you can print it directly from Spectre Cloud to use at the drill press, hand to a colleague, or file for your records. Spectre Cloud generates a clean, formatted printout that includes all measurements...

4.3.1   step-by-step Span measurements define the distance between the thumb hole and each finger hole. Spectre Cloud supports four span types, and it's important to enter values under the correct one — the number only means what it's supposed to when it's pa...

4.3.3   measurement The ring finger span is often derived from the middle finger span rather than measured independently, using the 5/16" Ring Finger Rule. Spectre Cloud can apply this calculation for you through Auto-Calculate Ring Span (2.6.8), or you can...

4.4.2   measurement When a bowler uses finger inserts, the spec sheet needs the insert type, the insert size (ID), and the drill bit OD for each finger. The order you enter them in matters — enter type and size first and Spectre Cloud's auto-suggestions do th...

4.4.3   concept Finger inserts seat in one of two ways — STD (Standard) or VACU (Vacuum). The insert type you record on the sheet (see 4.4.2) tells Spectre Cloud how the hole is drilled. This page explains the difference. For the OD-sizing concept, see 4.1.6....

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 ...

4.4.5   measurement Finger pitch is entered directly into the pitch tiles surrounding each finger hole on the spec sheet. There's no direction to "select" — the tile you put the value in is the direction. This page covers how to read and enter those tiles for...

4.4.6   measurement CLT (Center Line Transformation) is a fitting measurement that captures how a bowler's finger centerline relates to the ball's grip center. Spectre Cloud uses it to derive the lateral finger pitch. This page explains the two ways CLT is ...

4.5.1   thumb The thumb is the largest hole on the ball and the primary control point for the release. Before entering thumb measurements, the spec sheet asks you to set the thumb hole shape — Round or Oval. This choice affects only how you define the hole si...

4.5.2   thumb For a round thumb, the hole size is a single value entered on the spec sheet. The thumb section records both the O.D. (the drill/hole size) and, when a thumb insert or slug is used, the hole size the bowler's thumb actually sits in — the two are...

4.5.3   measurement Thumb pitch works exactly like finger pitch — you enter it into the pitch tiles around the thumb hole, and the tile is the direction. There's no direction to select from a dropdown. For the full mechanics of the pitch tiles, see 4.4.3; f...

4.5.4   thumb Many bowlers use a thumb slug or thumb insert rather than a bare thumb hole. This page covers recording the thumb insert on the spec sheet. The physical installation (drilling the pilot hole, seating, adhesive, finishing) follows your shop's sta...

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 ...
