Cutting Hardwood Joinery on the Wolfpawn
The Wolfpawn can cut repeatable, accurate joinery that's tedious or impossible by hand. Dadoes, rabbets, and simple mortise-and-tenon joints are all achievable.
Dado (Cross-Grain Slot)
A dado is a slot cut across the grain to house a shelf or panel.
Setup in Aspire:
- Draw a rectangle the width and depth of your dado
- Pocket toolpath, flat end mill, full depth in multiple passes
Settings (hardwood):
- 1/8" 2-flute, 9000 RPM, 700 mm/min, 1.5 mm DOC
Fit: Target 0.1–0.2 mm clearance — snug but slides in. Test with offcuts first.
Rabbet (Shoulder Cut)
A rabbet is an L-shaped cut along the edge, typically for panel insets or back panels.
Setup: Pocket toolpath cutting from the edge inward.
Same settings as dado. Run the cut from the edge — climb cut on the inner wall for cleanest results.
Simple Mortise
A rectangular pocket for a tenon.
Setup: Pocket toolpath, size to your tenon + 0.1–0.2 mm clearance.
Critical: CNC mortises have radiused corners — either:
- Round your tenon corners to match the bit radius
- Chisel the mortise corners square by hand
- Design tenon with rounded ends (preferred)
Box Joints (Finger Joints)
Repeatable finger joints are where CNC excels over hand tools.
- Design the finger pattern in Aspire (or use a dedicated plugin)
- Profile cut each finger with a 1/8" bit
- Multiple pieces with identical cuts = tight fitting joints
Fit: Add 0.1 mm clearance — joints should tap together with a mallet.
Tolerance Testing Workflow
Before cutting your real pieces:
- Cut a test joint in scrap of the same species
- Adjust clearance if too tight or too loose (typically 0.05–0.1 mm steps)
- Save the working file for future use
