Full-Service Milling

From Raw Stock to Ready-to-Install

Most lumberyards sell what is on the rack. If the dimension you need is not stocked, you are out of luck — or you are ripping it on a table saw yourself and hoping for the best. Boise Lumber operates differently. Our milling facility is a core part of our business, not an afterthought.

We invested in commercial-grade equipment — a 24-inch planer, a 16-inch resaw bandsaw, a four-head moulder, a straight-line rip saw, and supporting machinery — specifically so we can take any piece of lumber, reclaimed or new, and convert it into precisely what a project demands. No compromises, no workarounds, no settling for the closest standard size.

Our milling team includes operators with decades of combined experience running production wood shops. They understand feed rates, knife geometry, grain direction, and the unique challenges that reclaimed material presents — embedded metal, variable moisture, irregular dimensions, and species mixtures. If it can be milled, we can mill it.

What We Can Do

Milling Capabilities

Six core milling operations cover virtually every conversion scenario, from rough-sawn boards to finished profiles ready for installation.

Planing & Surfacing

Our industrial planer surfaces rough-sawn lumber to precise thicknesses with a smooth, consistent finish. We can plane one side (S1S), two sides (S2S), or all four sides (S4S) depending on your requirements. Maximum width capacity is 24 inches; maximum thickness is 8 inches.

Specs

  • Thickness tolerance: +/- 1/64"
  • Surface finish: 16-20 knife marks per inch
  • Maximum width: 24"
  • Maximum thickness: 8"
  • Minimum length: 24"

Resawing

Resawing splits thick stock into thinner boards along the width, allowing you to get multiple usable boards from a single thick plank. This is particularly valuable for reclaimed timbers where a single 4x12 beam can yield several 1-inch boards with consistent grain orientation. Our resaw bandsaw handles material up to 16 inches wide and 12 inches thick.

Specs

  • Maximum width: 16"
  • Maximum height: 12"
  • Minimum resaw thickness: 3/8"
  • Blade kerf: 3/32"
  • Consistent thickness throughout run

Tongue & Groove

Our moulder cuts precision tongue-and-groove profiles for flooring, paneling, and ceiling installations. We offer standard T&G profiles as well as variations with v-groove, bead, or flush joints. T&G milling is available on boards from 3/8-inch to 1-1/2-inch thick and 3 inches to 8 inches wide.

Specs

  • Standard tongue: 1/4" x 3/8"
  • V-groove, bead, or flush joint options
  • Board thickness: 3/8" to 1-1/2"
  • Board width: 3" to 8"
  • Face and back options available

Shiplap & Channel Rustic

Shiplap and channel rustic profiles create a clean, overlapping joint ideal for wall cladding, ceiling treatments, and exterior siding. We mill both standard shiplap (rabbeted edges) and channel rustic (with a reveal gap) in a range of board widths. These profiles are popular for barn wood accent walls and farmhouse-style interiors.

Specs

  • Rabbet depth: 3/8" to 1/2"
  • Channel reveal: 1/4" to 1/2" configurable
  • Board thickness: 1/2" to 1-1/4"
  • Board width: 4" to 8"
  • Nickel gap option available

Custom Moulding Profiles

We run custom moulding profiles using our four-head moulder and a library of standard knife sets. Crown moulding, baseboards, casing, chair rail, picture moulding, and quarter-round — all milled from the wood species of your choice, including reclaimed stock. Custom knife grinding is available for non-standard profiles with a one-week lead time.

Specs

  • Standard profile library: 50+ patterns
  • Custom knife grinding: 5-7 business day lead time
  • Maximum profile width: 8"
  • Maximum profile height: 5"
  • Minimum run length: 100 linear feet

Ripping & Straight-Line Ripping

Our straight-line rip saw cuts rough or irregular-edged boards to consistent widths with a clean, glue-ready edge. This is essential for processing live-edge slabs, random-width reclaimed boards, and rough-sawn stock into usable dimensional material. Ripping capacity handles boards up to 4 inches thick and 24 inches wide.

Specs

  • Width tolerance: +/- 1/32"
  • Clean, glue-ready edge
  • Maximum thickness: 4"
  • Maximum width: 24"
  • Laser guide for precision alignment

How It Works

Our Milling Process

01

Consultation & Specs

You tell us what you need — species, dimensions, profile, quantity, and finish requirements. We discuss material options, confirm feasibility, and provide a firm quote. If you are bringing your own material, we evaluate it for suitability before committing to a production run.

02

Material Preparation

Before milling begins, material is inspected for hidden metal, moisture content, and defects. Reclaimed stock goes through de-nailing and metal detection. All material is acclimatized and moisture-balanced to ensure consistent milling results. If material needs kiln drying before milling, we handle that in-house.

03

Milling & Quality Control

Production runs are set up to your exact specifications. We mill a test piece first and verify dimensions, profile accuracy, and surface quality before running the full order. Every batch is spot-checked during production, and finished material is inspected and measured before stacking.

04

Finishing & Delivery

Milled material is stacked, stickered, and banded for transport. If you need sanding, sealing, or staining, we can coordinate with our finish partners or apply basic sealers in-house. Delivery is available throughout the Treasure Valley, or you can pick up at our Beverly Street yard.

Project Examples

Common Milling Projects

These are the types of milling jobs we run every week. If your project is similar to any of these, we can give you a quick turnaround and accurate quote.

Reclaimed Barn Wood to Shiplap

We take rough, uneven barn boards and mill them into consistent-thickness shiplap with clean rabbet joints. Customers keep the weathered face for character while getting a flat back and tight-fitting edges for easy installation.

Timber Beams to Flooring

Large reclaimed timbers are resawn into 1-inch boards, then planed and milled with tongue-and-groove profiles for wide-plank flooring. A single 6x12 beam can yield five to six usable floor boards with spectacular old-growth grain.

Rough-Sawn Fir to Trim Packages

Contractors bring us rough-sawn Douglas fir and we mill complete trim packages — baseboards, casing, crown, and window stools — all from matching stock so the grain and color are consistent throughout the project.

Live-Edge Slabs to Tabletops

We flatten and thickness live-edge slabs using our wide-belt capabilities, then straight-line rip the joining edge for book-matched or multi-slab glue-ups. The natural edge is preserved; the rest is surfaced flat and parallel.

New Cedar to Fence Boards

We mill new western red cedar into custom fence pickets — dog-eared, flat-top, or French gothic profiles — in widths and thicknesses that standard retail stock does not offer. Popular for privacy fences and estate-style installations.

Reclaimed Oak to Stair Treads

Reclaimed oak planks are resawn to 1-1/4" thickness, planed smooth, and edge-jointed for wide stair treads. Bullnose or round-over profiles are applied to the leading edge. The result is a stair tread with century-old grain and a furniture-grade surface.

Pricing

Milling Rates & Turnaround

Milling is priced per linear foot or per board foot depending on the operation. Simple surfacing (planing) starts at competitive per-board-foot rates. Profile milling — tongue-and-groove, shiplap, moulding — is quoted based on profile complexity, material species, and run length.

Volume discounts apply to runs over 500 linear feet. Repeat orders with the same setup receive preferred pricing because setup time is reduced. We provide firm, written quotes before any work begins — no surprises on your invoice.

Standard turnaround is 3 to 5 business days for most jobs. Rush service (1 to 2 business days) is available for an expedite fee, subject to current shop load. Large production runs and custom knife orders may require longer lead times, which we communicate upfront during the quoting process.

Bring Your Own Material

You are welcome to bring your own lumber for milling. We charge milling fees only — no material markup. We evaluate incoming material for metal, moisture, and defects before processing. Material that cannot be safely milled (embedded metal we cannot remove, advanced rot, excessive moisture) will be flagged before we proceed.

Use Our Stock

Do not have your own material? Choose from our reclaimed or new lumber inventory and we will mill it to your specifications. Material cost plus milling fees — simple, transparent pricing with everything handled under one roof.

Minimum Order

Our minimum milling order is 50 linear feet for profile work and 25 board feet for planing. Smaller quantities can be accommodated but may carry a shop minimum charge to cover setup time. Custom knife orders require a minimum run of 100 linear feet.

More Project Examples

The Full Range of What We Mill

Beyond the common projects listed above, here are additional milling jobs that showcase the versatility of our equipment and team.

Reclaimed Pine to Ceiling Paneling

Rough-sawn reclaimed pine boards milled to 3/4-inch thickness with a V-groove tongue-and-groove profile. The weathered face is preserved on one side while the back is surfaced flat for uniform installation against ceiling joists or furring strips.

New Walnut to Butcher Block Strips

New black walnut boards ripped into 1-3/4-inch strips, surfaced on all four sides to uniform dimensions, and edge-jointed for glue-ready surfaces. These strips are laminated into butcher block countertops with alternating grain for strength and beauty.

Salvaged Gym Floor to Tabletops

Reclaimed hard maple gym flooring strips — complete with court line markings — are joined, flattened, and milled into tabletops that preserve the original playing surface as a visible design feature. A unique conversation-starting surface for restaurants and homes.

Cedar Logs to Sauna Boards

Raw western red cedar logs and cants are resawn into 1x4 and 1x6 boards, kiln-dried to 8 percent moisture content, planed smooth on all faces, and milled with a tongue-and-groove profile specifically dimensioned for sauna wall and ceiling installation.

Reclaimed Fir to Window Trim

Reclaimed Douglas fir boards surfaced and milled to match the original window casing profile in a 1920s Boise home. We replicate historical moulding profiles by grinding custom knife sets from sample pieces, ensuring seamless integration with existing trim.

Mixed Hardwood to Cutting Boards

Reclaimed oak, walnut, maple, and cherry offcuts are precision-ripped to uniform widths, cross-cut to length, and surfaced for edge-grain and end-grain cutting board lamination. We provide the prepared strips; the customer or our shop handles the glue-up.

Timber to Mantel Blanks

Reclaimed timbers are resawn to create mantel blanks — thick, wide slabs with one flat back face and one character face. We surface the back to sit flush against the wall, rip to consistent width, and trim to specified length. Customer finishes and installs.

New Oak to Stair Parts

New red oak boards milled into complete stair component packages: treads at 1-1/4 inch with bullnose profile, risers at 3/4 inch, and skirt boards at 3/4 x 11-1/4 inches. All components surfaced, profiled, and sanded to 120-grit in a single production run.

Reclaimed Redwood to Deck Boards

Old-growth redwood salvaged from a dismantled water tank is resawn into 5/4 x 6 deck boards with eased edges. The dense, tight-grained old-growth material offers decay resistance that surpasses any new redwood available today — a truly premium decking product.

Beetle-Kill Pine to Accent Boards

Blue-stained beetle-kill pine logs from Idaho forests are resawn into boards showcasing the distinctive blue-grey streaking caused by the fungus carried by mountain pine beetles. These boards are dried, surfaced, and profiled for accent wall installations that celebrate a natural phenomenon.

Our Equipment

Commercial-Grade Milling Equipment

Our facility is equipped with industrial woodworking machinery built for production runs, not hobby projects. Here is what powers our milling operations.

Industrial Thickness Planer

24-inch capacity, 8-inch maximum thickness, helical cutterhead with 72 carbide inserts, variable feed speed 16-40 FPM, 15 HP motor

Our primary surfacing machine handles everything from thin veneer stock to 8-inch-thick timber. The helical cutterhead produces a superior finish with reduced tear-out compared to straight-knife planers, and individual carbide inserts rotate to present fresh edges, extending service intervals significantly.

Resaw Bandsaw

16-inch wheel, 12-inch maximum resaw height, 1.5-inch blade width, 3/32-inch kerf, hydraulic feed

Purpose-built for splitting thick stock into thinner boards while maintaining consistent thickness throughout the cut. Hydraulic feed provides uniform pressure and speed control critical for clean, parallel resaw cuts in dense hardwoods and old-growth reclaimed material.

Four-Head Moulder

8-inch maximum width, 5-inch maximum height, 4 independent cutterheads, 50+ standard knife sets, 7.5 HP per head

The heart of our profile milling operation. Four independently adjustable cutterheads shape all four faces of a board in a single pass — top, bottom, and both edges simultaneously. This produces tongue-and-groove, shiplap, moulding profiles, and custom shapes with perfect registration between all four surfaces.

Straight-Line Rip Saw

24-inch capacity, 4-inch maximum thickness, laser alignment guide, carbide blade, 10 HP motor, power feed

Rips rough or irregular-edged boards to consistent widths with a clean, glue-ready edge in a single pass. The laser guide projects a cut line on the board surface, allowing the operator to optimize grain orientation and minimize waste when ripping reclaimed stock.

Industrial Metal Detector

Ferrous and non-ferrous detection, conveyor-mounted, adjustable sensitivity, audio and visual alert

Every board that enters our milling line passes through the metal detector first. Reclaimed lumber frequently contains embedded nails, screws, staples, wire, and even bullet fragments. Catching these before they reach a saw blade or planer knife protects both equipment and operators.

Wide-Belt Sander

36-inch belt width, dual-head (80-grit and 120-grit), variable speed feed, 20 HP combined motor

For projects requiring sanded surfaces — tabletops, countertops, stair treads, and furniture panels — our wide-belt sander produces flat, uniform surfaces. The dual-head configuration handles initial stock removal and finish sanding in a single pass.

Kiln Dryer

2,000 board-foot capacity, dehumidification system, digital temperature and humidity controls, data logging

Our in-house kiln allows us to dry green lumber, re-condition reclaimed stock with elevated moisture, and heat-treat material to ISPM 15 standards. Digital controls maintain precise temperature and humidity profiles tailored to species and thickness for optimal drying without defects.

Dust Collection System

5,000 CFM capacity, cyclone separator, cartridge filtration, automated damper gates, central network to all machines

Industrial dust collection serves every machine in the facility, maintaining clean air and capturing sawdust and chips for recycling into mulch and animal bedding products. The system exceeds OSHA requirements for wood dust exposure limits and reduces fire risk from accumulated dust.

Species Guide

How Different Species Mill

Different wood species respond differently to milling operations. Understanding these characteristics helps set realistic expectations for your project.

SpeciesMachinabilityTear-Out RiskSurface QualityNotes
Douglas FirGoodLowClean, smoothMills predictably. Old-growth fir machines better than new-growth due to tighter grain.
White OakModerateModerateExcellentDense — requires sharp tooling and slower feed rates. Produces beautiful quartersawn faces.
Red OakGoodLow-ModerateVery GoodOpen pores can raise during milling. Planes and profiles well with sharp knives.
Hard MapleModerateModerate-HighExcellentVery hard — can burn with dull blades or slow feed. Figured maple requires climb cuts or very shallow passes.
Black WalnutExcellentLowSuperiorOne of the best-milling domestic hardwoods. Clean cuts, smooth surfaces, minimal tear-out.
Western Red CedarExcellentVery LowGoodVery soft — requires sharp edges to cut cleanly rather than crush fibers. Light feed pressure.
Pine (White/Ponderosa)GoodLowGoodResin can gum blades in warm conditions. Clean, easy milling when dry and properly conditioned.
Heart PineModerateLowExcellentExtremely dense and resinous. Mills cleanly but is hard on tooling. Resin buildup requires frequent blade cleaning.
CherryExcellentLowSuperiorMachines beautifully with minimal effort. Burns easily on end-grain cuts — keep blades sharp and feed rates up.
HickoryDifficultModerateGoodExtremely hard and tough. Carbide tooling essential. Interlocked grain can cause tear-out. Slow feed recommended.

Precision Standards

Tolerances & Quality Specifications

Commercial milling is about consistency. When you order 500 pieces of tongue-and-groove paneling, every board needs to fit with every other board. That requires tight tolerances and rigorous quality control throughout the production run.

Our equipment is calibrated regularly, and our operators verify dimensions against specifications on the first piece, at regular intervals during production, and on the last piece of every run. Any drift in dimensions triggers an immediate correction.

For applications requiring tighter tolerances than our standard specifications — such as precision furniture components, musical instrument parts, or critical joinery — we can accommodate tighter specs with additional time and care. Discuss your requirements during the consultation phase and we will confirm what is achievable.

Planing (Thickness)

+/- 1/64" (0.015")

Consistent across full board width and length. Measured at multiple points per board.

Planing (Surface Finish)

16-20 knife marks per inch

Helical cutterhead produces near-sanded surface quality direct from the planer.

Resawing (Thickness)

+/- 1/32" (0.031")

Bandsaw resaw has slightly wider tolerance than planer. Resawn faces are typically planed after for tighter finish.

Ripping (Width)

+/- 1/32" (0.031")

Clean, glue-ready edge. Laser-guided for consistent alignment through the full board length.

T&G Profiles

+/- 1/64" on tongue/groove

Profile depth and width held to tight standards ensuring proper fit across the full production run.

Moulding Profiles

+/- 1/32" on profile shape

Standard profiles held tightly. Custom profiles verified against template or sample before production.

Scheduling

Turnaround Times by Job Type

Turnaround depends on job complexity, material volume, and current shop load. Here are typical timelines for common milling operations.

Planing Only (S2S/S4S)

1-2 business days

The simplest milling operation. Material passes through the planer to uniform thickness and/or smooth surfaces. High throughput — we can plane 1,000+ board feet per day.

Resawing

2-3 business days

Slower than planing due to the precision required for consistent thickness through the full board. Large timbers take longer per piece. Resawn material typically receives a follow-up planing pass.

T&G or Shiplap Profiling

3-5 business days

Moulder setup takes 30-60 minutes per profile change. Once set, production runs quickly. Larger orders (1,000+ LF) may extend to 5-7 days depending on shop load.

Custom Moulding (Standard Knife)

3-5 business days

Uses existing knife sets from our 50+ profile library. Setup and test run, followed by production. Standard profiles are typically completed within the standard turnaround window.

Custom Moulding (Custom Knife)

7-10 business days

Custom knife grinding adds 5-7 days before milling can begin. We work with a local knife grinding service to produce custom profiles from your sample or drawing.

Complete Package (Multiple Operations)

5-7 business days

Jobs requiring multiple operations — resawing, planing, profiling, and sanding — are staged through the shop in sequence. Complex packages with kiln drying may extend to 2-3 weeks.

Rush service available: 1-2 business day turnaround for qualifying jobs with a 25% expedite fee. Subject to current shop load. Call to confirm rush availability before placing your order.

Profile Library

Custom Profile Options

Our four-head moulder can produce virtually any linear wood profile using standard or custom knife sets. We maintain a library of over 50 standard profiles that cover the most common moulding, paneling, and siding profiles used in residential and commercial construction.

For profiles not in our standard library, we work with a local knife grinding service to produce custom knife sets from your sample piece, scale drawing, or CAD profile. Custom knives are a one-time cost — once ground, they are stored in our facility for future orders at no additional knife charge.

Historical restoration projects are a particular strength. If you need to match existing moulding in a vintage home — crown, base, casing, chair rail, or picture moulding from any era — bring us a sample piece and we will replicate the profile exactly. We have matched profiles from 1890s Victorian homes, 1920s Craftsman bungalows, and 1940s mid-century residences throughout the Boise area.

Standard Profiles Available

Tongue & Groove (standard)

Tongue & Groove (V-groove)
