Material Notes

Boards are cut by hand, so minor size variations may occur. Actual dimensions will be very close to the listed 19.75" × 11.75" size.

Because Baltic Birch can develop some bow or warp at this thickness, hold-down pins, magnets, or other work-holding methods may be helpful during laser cutting. We do our best to ship flat, usable sheets.

Laser Settings

Glowforge users can use Medium Basswood Plywood / Proofgrade-style settings as a starting point. Settings may need to be adjusted based on your specific laser, tube power, optics, airflow, material batch, and machine condition.

Shipping

UPS shipping is included for addresses within the contiguous United States. Please do not use this listing for PO boxes or destinations outside the contiguous United States.
