Building a T-Track Clamping System for the Wolfpawn

The stock Wolfpawn has limited built-in workholding. Adding T-tracks to the spoilboard gives you proper, flexible clamping for any workpiece size.

What You Need

• T-track aluminum extrusion — 15mm or 19mm slot, cut to length (~400mm)
• T-track clamps (step clamps) — adjustable height to match material thickness
• T-nuts and M5 bolts — to mount track to spoilboard
• MDF or HDPE for spoilboard replacement

Layout

Two tracks running parallel to the X axis give the most flexibility:

• Space them ~120mm apart (allows clamping most common stock widths)
• Mount flush to the spoilboard surface — they shouldn't protrude above work surface

Alternatively: run tracks at the front and back, or all four for maximum flexibility.

Installation

1. Route grooves in MDF spoilboard to seat the T-track flush
2. Use CNC to cut precise groove: exact track width + 0.1mm clearance, depth = track height
3. Bolt tracks into grooves from below (countersunk into spoilboard underside)
4. Or use construction adhesive + screws from top if routing is too complex
5. Resurface spoilboard after installation

Using T-Track Clamps

Step clamps work by hooking one end under the workpiece and the other into the T-track:

• Loosen the T-nut, slide clamp to position
• Adjust step height to match material thickness
• Tighten — the clamp pivots down onto the workpiece

Use at least 4 clamps on a full sheet, 2 minimum on smaller pieces.

Clamping Outside the Cut Path

Critical rule: clamps must never be in the toolpath. In Aspire, enable Clamp Safe Height or manually verify clamp positions against your toolpath simulation.

Other Workholding Options for the T-Track

• Hold-down dogs for long boards against a fence
• Toe clamps machined from MDF for close workholding
• Vises — small machine vises can bolt into T-tracks for repeat-position work
