Bill of Materials, Hardwood Species & Shop Tooling for Radius Gauge Set
Accurate stock preparation is half the battle when building the Radius Gauge Set. Verify your blank dimensions and thickness before adhering the template or zeroing your CNC/laser axis:
| Part Name | Qty | Stock Thickness | Part Bounding Box (W × H) |
|---|---|---|---|
| Gauge 1/8 | 1 | 1/8" | 3" × 1" |
| Gauge 3/16 | 1 | 1/8" | 3" × 1" |
| Gauge 1/4 | 1 | 1/8" | 3" × 1" |
| Gauge 5/16 | 1 | 1/8" | 3" × 1" |
| Gauge 3/8 | 1 | 1/8" | 3" × 1" |
| Gauge 1/2 | 1 | 1/8" | 3" × 1" |
| Gauge 5/8 | 1 | 1/8" | 3" × 1" |
| Gauge 3/4 | 1 | 1/8" | 3" × 1" |
Recommended Hardwood & Sheet Stock Selection
For laser-cut finger-joint boxes and desk organizers, use void-free Baltic Birch plywood (B/BB grade) or hardwood-core veneered MDF/plywood, and always measure actual sheet thickness with digital calipers before cutting. For CNC-routed keepsake boxes, valets, trivets, and wall racks, select kiln-dried American Black Walnut, Hard Maple, Cherry, or White Ash planed dead-flat so pocket depths and through-tenon shoulders register with sub-thousandth accuracy.
Required Shop Tools, Blades & Bits
- Laserbox 40W CO2. Red = cut, blue = engrave the labels.
- Labels are text in the SVG and DXF. If your laser software doesn't import text, type the labels in it before engraving.
- Acrylic works too and lasts longer; kerf hardly matters at these sizes.
- 40W+ CO2 or Diode Laser Cutter with honeycomb bed & air assist
- PVA wood glue, painter's tape for clamping, and 180–220 grit sandpaper to clean laser edges
- Hardware: A 1" key ring to keep the set together.
How to Cut, Carve & Assemble the Radius Gauge Set
Follow this numbered shop sequence to take your Radius Gauge Set from rough lumber to a crisp, heirloom-grade piece ready for finishing:
Step 01
Measure Actual Stock Thickness & Verify Machine Setup
Before running your machine, measure your actual stock thickness with digital calipers (nominal stock: 1/8" (3 mm) plywood or acrylic, one 14" x 10" sheet). Import the color-layered SVG or DXF into your laser software at 100% scale (inches). Assign Red lines to Cut and Blue lines/text to Score/Engrave.
Step 02
Machining & assembly stage 1
Engrave the labels, then cut.
Step 03
Machining & assembly stage 2
Check the 1/2" gauge against a known 1/2" roundover bit cut to confirm the scale.
Step 04
Machining & assembly stage 3
Ring them together through the holes.
Pro Shop Tips & Common Mistakes to Avoid
1. Grain Orientation & Short-Grain Strength
Always orient the long grain of your board strictly parallel to the X-axis (left-to-right on the template). Diagonal grain runout across a narrow utensil neck, hook tenon, or featherboard finger creates short grain that can snap under everyday load.
2. Progressive Sanding (120 → 180 → 220 Grit)
Never skip grits or sand raw hardwood above 220 grit before applying natural polymerizing oils. Over-polishing raw wood to 400+ grit burnishes the wood cells shut and prevents DuraGrain Walnut Oil or Hardwax Oil from anchoring deep inside the fibers.
3. Water-Popping & Wiping Excess Oil Dry
For kitchen utensils and trivets, misting with warm water before your final 220-grit pass eliminates raised-grain fuzz permanently. When applying DuraGrain finishes, always wipe the surface 100% bone-dry after 15–20 minutes so the oil cures inside the wood rather than turns tacky on top.

The DuraGrain Single-Coat Architectural Cure Protocol for Radius Gauge Set
Whether you cut the Radius Gauge Set on a CNC router or a CO2/diode laser, spray lacquer and wipe-on polyurethane pool inside finger joints, gum up kerf-cut living hinges, and leave a plastic film that peels or clouds over time. DuraGrain Hardwax Oil bonds molecularly inside the wood grain in a single wipe-on, buff-off application—with 0.0 g/L VOCs and zero toxic fumes in your shop:
Step 01 • Scrub In with #0000 White Pad
Apply Thinly with the Included 3"×4.5" #0000 Non-Abrasive Pad
Sand all surfaces to 180–220 grit (cleaning any laser char from finger tabs if applicable) and vacuum away dust. Pour a small ribbon of DuraGrain Hardwax Oil (12 fl oz) and work it evenly into the wood using the included 3"×4.5" #0000 white non-abrasive palm pad. The pad shears the Pure Chinawood Tung Oil, Refined Walnut Oil, and T1 Carnauba Wax deep into end-grain pockets, dados, and miters without runs or sags.
Step 02 • 15-Minute Buff-Off
Buff Bone-Dry with the Included Dark Charcoal Microfiber Cloth
Allow the oil-wax blend to penetrate for 15 minutes, then buff the entire piece completely dry using the included 12"×12" 300 GSM edgeless dark charcoal microfiber buffing cloth. Because our formula cures by oxidative cross-linking rather than solvent evaporation, it leaves a dead-flat, velvet-matte tactile finish that highlights natural walnut, maple, cherry, or Baltic birch figure and spot-repairs effortlessly.
