• stowage_factor

  Stowage factor SF = cargo volume (m3) / cargo mass (tonnes), with classification against the IMO CSS Code Table 4.1 reference ranges for wood cargoes (sawn timber, tropical logs, plywood...).

• container_loading

  How many uniform cartons fit in a shipping container before cube-out or weigh-out. Presets: 20GP (33.2 CBM nominal, 28,200 kg payload), 40GP (67.7 CBM, 26,700 kg), 40HC (76.4 CBM, 68 usable, 26,500 kg) — all editable. Returns max pieces by volume vs weight, the binding limit, balanced density (kg/m3) and containers needed for a planned quantity.

• sawmill_recovery

  Sawmill recovery rate (lumber recovery factor): sawn volume out / roundwood volume in, benchmarked against FAO/EU/SE-Asia reference ranges. Also computes log-rule overrun/underrun: (actual BF - rule BF) / rule BF — Doyle underestimates small logs, so overrun is usually positive.

• moisture_content

  Wood moisture content (WH-2021 Ch.4 Eq. 4-1..4-4). Two modes: (1) sample-based MC_od/MC_wb from wet+dry masses; (2) drying outcome — mass + water lost when going from start MC to target MC. Optional Gb (kg/m³) returns MCmax and MCsink. Basis 'od' (oven-dry, industry default) or 'wb' (wet).

• wood_shrinkage

  Wood shrinkage from a start MC to an end MC (WH-2021 Eq. 4-9: S_x = S_od × (1 − x/FSP)). Direction: tangential (board width) or radial (board thickness) or volumetric. Picks a species from the wood-species table (16 verified species) or accepts custom S_od + FSP. MC is clamped to FSP — above FSP wood doesn't change dimension.

• wood_emc

  Equilibrium moisture content (EMC) from temperature and RH using the Hailwood–Horrobin sorption model (Simpson 1973 coefficients, desorption branch — WH-2021 Ch.4 Table 4-2). Optional reverse mode: target MC → required RH at the given temperature.

• kiln_capacity

  Kiln charge capacity: wood volume per batch (AH-188 / TechDrying). V_wood = D×R×C × t/(t+s) × f where t=board thickness, s=sticker thickness, f=fill factor (0.85–0.95). Returns wood volume in m³ and board feet (1 m³ = 423.77 BF).

• rough_sizing

  Rough sizing — convert between finished (planed, kiln-dried) and rough-sawn dimensions before drying and planing. Adds planing allowance (default 2.5 mm/face) + saw kerf (default 2.2 mm band) and applies WH-2021 Eq. 4-9 shrinkage. Direction: tangential (board width) or radial (board thickness).

• firewood_calculator

  Convert firewood volume between cord (128 ft3), stere/Raummeter (stacked m3), solid m3 (Festmeter), loose m3 and ft3, with optional weight estimate by wood species (dry/fresh).

• rpm_calculator

  Spindle speed (RPM) from cutting speed: n = Vc*1000/(pi*D) metric, n = Vc*12/(pi*D) imperial. Metric takes diameter in mm and Vc in m/min; imperial takes diameter in inches and Vc in SFM. Includes a web_url with the calculation prefilled.

• cutting_speed_calculator

  Cutting speed from spindle speed: Vc = pi*D*n/1000 metric (m/min), SFM = pi*D*n/12 imperial. Always also returns the same speed converted to the other unit system. Includes a web_url with the calculation prefilled.

• timber_beam_capacity

  Allowable load on a simply supported rectangular timber beam (planning estimate, Eurocode 5 conventions, EN 338 grades C16-D40/D24-D40). Returns allowable UDL and center point load (gross and net of self-weight), governing mode (bending vs deflection at L/300), utilization, section properties. NOT a structural design - verify with an engineer. Includes a web_url with the beam prefilled.

• glass_price_calculator

  Cut-to-size glass cost and weight estimate: net area with optional waste allowance, weight (2.5 kg/m2 per mm of thickness), material cost from your price per m2, optional polished-edge work per running metre, total and per-piece cost. Includes a web_url with the quote prefilled.

• manufacturing_yield

  Cumulative yield through a wood production chain (sawing -> drying -> machining -> finishing). Multiplies stage yields, shows per-stage loss and computes the roundwood volume needed for a target finished volume.

• glue_consumption

  Wood adhesive quantity: bond area x spread (g/m2, TDS presets like PVAc D3 175, EGP 250, finger-joint PUR 530) x application faces x waste allowance. Also computes bond area for edge-glued panels (joints from board width) and face lamination lay-ups.

• paint_coverage

  Wood finishing paint quantity. Technical route: theoretical coverage = 10 x %volume solids / DFT(um), multiplied by transfer efficiency (conventional spray 30-35%, airless ~50%, HVLP ~65-90%, brush/roller ~90%); or a data-sheet coverage in m2/L. Adds an optional extra % for carved/3D surfaces.

• cbm_shipment

  Packing CBM for cartons: per-line and lot volume (m3), total weight and lot density, with a cube-out / weigh-out verdict against the 40HC balanced density (390 kg/m3 - same presets as container loading).

• bom_costing

  Bill-of-materials cost roll-up for furniture: buy quantity = net qty x (1 + waste%, verified presets: S4S lumber 18%, rough 28%, nested panels 10%, hardware 3%), line and total costs, cost per product and a selling price from a target margin (price = cost / (1 - margin)).
