Moulding guide
Optimize stock only after member lengths are known.
The moulding planner packs verified outside long-point lengths into stock sticks. It does not derive them from a frame opening because profiles, rabbets, and saw references differ.
Prepare reliable lengths
- Establish the frame geometry using the actual profile and joining method.
- Make or calculate one matching long and short pair, then verify the intended opening.
- Measure outside long points using the same reference for every member.
- Enter each verified length and quantity into the stock planner.
- Reduce usable stock lengths for defects or pattern matching before optimizing.
Set the allowances
- Kerf: use the material removed by the blade for each reserved member.
- End trim: reserve enough at both ends to square or clean the stock.
- Pattern and grain: add manual allowances when matching matters.
A mathematically fitting plan is not proof that mitres will close. Verify saw calibration and the first matching pair before cutting the batch.
