wood

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.

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.

baluster

baluster_spacing_calculator

Equal baluster/spindle spacing for a run: number of balusters, exact gap and positions. Enforces a maximum gap (e.g. the 4-inch / 100 mm sphere code rule).

Calculate board feet and lumber cost (thickness x width x length / 144 in inches). Accepts multiple boards and an optional price quoted per board foot or per MBF (thousand board feet).

bom

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)).

cbm

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).

cnc

CNC spindle RPM and feed rate from tool diameter, flute count, chip load and cutting speed. Works for routers and mills, metric and imperial.

container

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.

cutting

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.

embroidery

embroidery_resize

Resize an embroidery design file (PES or DST) by a scale percentage. Returns stitch stats before/after, a density safety verdict (safe within +/-15%) and the resized file as base64.

firewood

firewood_calculator

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.

glue

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.

green

green_log_weight

Weight of a roundwood/log batch at any moisture content: W = volume x basic density x (1 + MC/100), per USDA Wood Handbook 2021 Ch.4. Presets for 14 verified species (acacia, rubberwood, eucalyptus, oak, teak, spruce...) or a custom basic density. Returns oven-dry mass, water mass and tonnes.

hoppus

hoppus_volume

Hoppus (quarter-girth) volume of round logs from mid-length circumference and length: (C/4)^2 x L. Returns Hoppus volume, true volume (x 4/pi), Hoppus tons (50 h ft3) and a board-feet approximation, with optional quantity and value per Hoppus unit.

jas

jas_log_scale

Japanese Agricultural Standard (JAS) log scale: official diameter rounding (floor to 1 cm below 14 cm, even 2 cm at 14 cm and above), oval-log averaging, optional +2 cm ovality adjustment and the length allowance for logs over 6 m. Volume per log and totals in m3.

kiln

lumber

lumber_weight_calculator

Weight of lumber by species, dimensions, quantity and moisture (dry/fresh), using species density tables. Optional custom density in kg/m3.

manufacturing

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.

metal

metal_weight_calculator

Weight of metal stock per profile: pipe/tube (OD + wall), round bar, square/rectangular tube, flat bar, angle, beam/I-beam. Materials: steel, stainless, aluminum, copper, brass.

miter

moisture

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).

paint

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.

rebar

rebar_takeoff

Rebar weight takeoff (d2/162 rule): total length, weight in kg and bars per tonne for a list of rebar lines. Supports metric mm bars and US # sizes as diameters.

rough

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).

rpm

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.

sawmill

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.

stowage

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...).

tile

tile_calculator

Tiles, boxes and cost for a room: room and tile dimensions, grout width, waste factor by layout pattern (straight, offset, diagonal, herringbone...), optional box size and prices.

wallpaper

wallpaper_calculator

Wallpaper rolls needed for a wall, accounting for pattern repeat and openings. Use a standard roll preset (eu, us-single, us-double, commercial54) or custom roll dimensions.

NestingCalc Calculators — questions

Answers built from our own checks of this server.

What can NestingCalc Calculators do?

It exposes 37 tools, read directly from the server on our last check. Among them: baluster_spacing_calculator, board_feet_calculator, bom_costing, cbm_shipment, cnc_feeds_speeds, container_loading and 31 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is NestingCalc Calculators mostly used for?

Its tools cluster around timber, sheet and wood. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is NestingCalc Calculators working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 365 ms. The bar chart above shows every period we have measured.

How do I connect NestingCalc Calculators?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does NestingCalc Calculators need an API key?

No. NestingCalc Calculators completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 37 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is NestingCalc Calculators?

It answers our handshake in 365 ms on average, which is faster than 40% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
