Does Mortise include 4/4 hardwood?

Not as its own size. Hardwood comes as 5/4, 6/4 and 8/4; for ¾″ parts use a 1x board in any hardwood species, or resaw thicker stock.

Can I use glued-up panels or butcher block?

No. Mortise stocks raw lumber and sheets only. Glue boards edge to edge yourself and the glue-up acts as one piece when you cut it.

Can I use inches and millimetres?

Yes. Mortise works in either. Lengths read to 1⁄64″ or 1 mm, and typed values such as 2-1/4″ or 610mm are kept exactly as typed.

Real lumber sizes

Why is a 2x4 not two inches by four in Mortise?

Because it is not at the lumberyard either. Mortise draws every board at its real, surfaced size and charges for it by its nominal size, the way it is sold, so the model fits together the way the wood will.

Open Mortise All features

Dimensional lumber

Nominal names, actual sizes.

Every section can be any of the twelve species, from SPF and pressure-treated to white oak, cherry and black walnut.

1x2 to 1x12: ¾″ thick: 1½″, 2½″, 3½″, 5½″, 7¼″, 9¼″ and 11¼″ wide.
2x2 to 2x12: 1½″ thick, at the same widths.
4x4 and 6x6: 3½″ and 5½″ square.

Hardwood

Hardwood by the quarter.

Rough hardwood is sold by its thickness in quarter inches and planed down before you use it. Mortise uses the surfaced thickness.

5/4: 1¹⁄₁₆″ thick, 5½″ wide.
6/4: 1⁵⁄₁₆″ thick, 5½″ wide.
8/4: 1¾″ thick, 5½″ or 7¼″ wide.

Metric

Planed timber in millimetres.

In millimetres, softwood is named by its real section: 22×95 to 22×145 boards, 34 mm battens, 45×45 to 45×195 studs and joists, and 70 and 95 mm posts.

Sheet goods

Sheets at the thickness they really are.

Plywood sold as ¾″ is 23⁄32″, and Baltic birch sold as ¾″ is 18 mm. Mortise uses the real thickness so dadoes and rabbets fit the sheet you will buy.

There are ten kinds: plywood, hardwood ply and veneered MDF with a choice of face veneer, bending ply, Baltic birch, MDF, OSB, particleboard, melamine and hardboard, in 4′×8′ sheets (5′×5′ for Baltic birch) or their metric equivalents.
