Finding ash wood lumber that arrives flat, stable, and ready to mill is the single most frustrating part of any woodworking project. One bowed board can throw off joinery for a dining table, and one splintered edge kills the clean lines of a live-edge bench. The difference between a rewarding build and a wasted afternoon comes down to how the lumber was kiln-dried, surfaced, and graded before it ever reaches your shop.

I’m Min — the co-founder and writer behind Gadgets Feed. My weekend workshop sees constant use with hand planes and drum sanders, and I’ve spent dozens of hours cross-referencing moisture content, surface quality, and customer reports across the major online hardwood suppliers to separate the consistent stock from the gamble.

This guide lands squarely on the six-pack of kiln-dried, S2S ash boards from Forest 2 Home — the ash wood lumber bundle that delivers tight grain, true faces, and a pencil in the box so you can start laying out cuts the moment you open the package.

How To Choose The Best Ash Wood Lumber

Ash is prized for its open grain, high shock resistance, and ability to steam-bend into chair backs and hockey sticks. But buying it online introduces variables that are invisible on a store shelf. Nail down these factors before you click purchase, and you will get boards that behave predictably under the saw.

Grading and Surface Finish

Look for lumber labeled S2S (surfaced two sides). That means the faces are jointed flat, which eliminates most twist and cup. FAS (First and Second) grade offers the fewest defects per board length, while Common grades allow more knots but cost significantly less. For visible furniture, FAS or Select is the safe bet; for shop jigs and cutting boards, Common works fine.

Kiln Drying and Moisture Content

Ash that has not been properly kiln-dried to 6–9% MC will move as it equilibrates to your shop’s humidity. Look for explicit “kiln dried” verbiage and, ideally, a stated moisture range. The Forest 2 Home bundle tested here arrives at shop-ready dryness, which is why the boards stay straight even after you break the shrink-wrap.

Dimensional Consistency

Nominal dimensions (1×6) are almost never the actual size. Expect ¾” to 15/16″ actual thickness and width to be roughly ½” less than nominal. The product listing should state both nominal and actual measurements. Also check whether the stock is “hit or miss” for thickness — S2S boards still need a final pass through the planer if you need precision joinery.

1. Forest 2 Home Ash Lumber Bundle — 1×6×24, 6 Board Pack

6 BoardsIncludes Carpenter Pencil

This is the bundle that prompted this entire guide. Six boards of kiln-dried ash, S2S, with actual thickness at 15/16″ and a 6-inch width that gives you real real estate for tabletops, breadboards, or wide panel glue-ups. Customer reports consistently call out zero bows, cups, or twists — a level of consistency that is rare for online hardwood orders. The open ash grain takes stain evenly, and the light cream-to-tan color provides a clean canvas for any finish.

Each board goes through Gutchess Lumber’s quality process with no harmful chemicals, and the listing explicitly states that unsound defects are absent on one face. The “hit or miss” finish means you will still want to run the boards through a planer if you need precision joinery, but the faces arrive flat enough that many users skip the jointer entirely. The included carpenter pencil is a small touch that signals attention to detail.

For a woodworker who needs a reliable supply of ash for a single large project or multiple small builds, this six-pack eliminates the uncertainty of sourcing from a big-box store. The boards are straight, the grain is clean, and the price per board foot lands in the sweet spot of the mid-range — you are paying for confidence, not just wood.

Why it’s great

  • Consistently flat and straight out of the box
  • 6″ width perfect for panel glue-ups
  • Kiln dried to shop-ready moisture

Good to know

  • Not S4S — still needs planer for final thickness
  • Nominal 1×6 is actually 15/16″ × 5½″

2. Barrington Hardwoods White Ash Turning Blanks — 2×2×6, 4 Pack

Lathe Blanks1-15/16″ Actual

If ash end-grain turning is your goal — bowls, pepper mills, or spindle work — these Barrington Hardwoods blanks deliver a full 2-inch square profile that cleans up to 1-3/4″ under the lathe. The kiln-dried ash holds its shape during roughing, and the white sapwood provides the high-contrast grain that finishers love. Reviewers note that the blanks arrive square and flat, with none of the twist that makes mounting on a lathe a headache.

The “hit or miss” surfacing on one side means some pieces may have a slightly rough edge, but every verified purchase report confirms the wood itself is free of cracks and splits. A reviewer who glued them together to make a small tabletop mentioned that no planing was needed. The measured density runs about 36.5 lb/cu.ft., which is right on spec for white ash.

These blanks are a solid choice for turners who want a reliable source of ash without driving to a specialty lumber yard. The 2×2×6 size is versatile enough for small bowls, handles, and hollow forms. Stick them in the sun for a day if you want the ash to lighten slightly before finishing.

Why it’s great

  • Full 2″ square stock for turning
  • Kiln dried for stability on the lathe
  • Consistent shape across all four blanks

Good to know

  • Edges may have mild rough spots
  • Not intended for wide panel work

3. Exotic Wood Zone Mixed Hardwood Bundle — 15 Boards (5 Walnut, 5 Cherry, 5 Maple)

3 Species6-9% Moisture Content

Fifteen boards in three domestic species — walnut, cherry, and hard maple — all surfaced and kiln dried to 6–9% MC. The ¾×2×24 size is ideal for cutting boards, serving trays, and small box projects. Buyers consistently praise the straightness of the boards, with almost no warping. The walnut boards show consistent dark chocolate color without pale sapwood streaks, the cherry has a warm reddish tone, and the maple (described by one reviewer as “eh” compared to the others) still works fine as an accent species.

Moisture content this low means minimal movement after you glue up a panel. The pencil included with the order is a nice bonus. The only recurring hiccup is shipping time — some customers report Amazon fulfillment taking up to two weeks despite an “in stock” label. If your project deadline is tight, order ahead.

This bundle is the most economical way to stock a small shop with three species for multi-wood projects. The cost per board is lower than buying individual bundles of each species, making it a smart choice for weekend woodworkers who want variety without a trip to the lumber yard.

Why it’s great

  • Three species in one box for mixed-wood builds
  • Low 6–9% MC for dimensional stability
  • Straight, flat boards out of the box

Good to know

  • Shipping can take up to 14 days
  • Maple may be less visually striking than walnut or cherry

4. Barrington Hardwoods Purpleheart Lumber Board — 3/4×6×18, 2 Pieces

S4SKiln Dried

Purpleheart is one of the hardest domestic exotics — Janka rating around 2,520 — and this S4S board from Barrington Hardwoods arrives smooth on all four sides, ready for final dimensioning. The two pieces in this pack measure ¾×6×18 and are kiln dried for stability. A reviewer noted that the wood looks gray on arrival but turns a rich violet-purple after a couple days of sunlight exposure.

One user building a guitar specifically praised the board’s clarity, and a luthier-level grain evaluation confirms tight, consistent figure. Another reviewer attempting a routed dovetailed wine rack discovered that purpleheart will destroy router bits if you push too hard — this material demands sharp carbide tooling and light passes. That density also means it makes an excellent mallet head or knife handle.

If you need a premium accent species for small furniture pieces, musical instruments, or decorative inlays, these purpleheart boards deliver the vivid color shift that ash simply cannot match. Just plan for the tool wear and let the UV exposure do the color work.

Why it’s great

  • S4S finish eliminates most prep work
  • Dramatic UV-reactive purple color
  • Perfectly flat and straight boards

Good to know

  • Extremely hard — needs sharp carbide tooling
  • Color takes days of UV exposure to develop

5. Forest 2 Home Hard Maple Bundle — 1×5×24, 4 Board Pack

4 BoardsCarpenter Pencil

Hard maple from Forest 2 Home — four boards at nominal 1×5×24, actual 15/16×4½×24. The S2S surfacing gives one clean face with no unsound defects, though you will still need to flatten, plane, and sand to final dimensions. Reviewers who made charcuterie trays and cribbage boards reported that the maple grain comes alive with a simple oil finish, and the shallow saw marks sand out in a couple minutes.

One customer experienced a size mix-up (received 2″ boards instead of 5″) but noted that Barrington Hardwoods issued an immediate refund — a sign of responsive customer service. Two of the four boards in one order had a slight bow, but the buyer was planning to mill them to 9/16″ anyway, so it was not a dealbreaker. The included carpenter pencil is a consistent touch across all Forest 2 Home bundles.

This pack is a reliable source of domestic hard maple for kitchen accessories, small furniture, and shop projects. The light creamy color pairs well with ash if you want a two-tone cutting board, and the price per board foot is competitive with box-store pricing minus the drive.

Why it’s great

  • Clean maple grain for oil finishes
  • Light color for dye or stain experimentation
  • Good customer support from seller

Good to know

  • Occasional slight bow in some boards
  • Not S4S — needs flattening

6. Forest 2 Home Cherry Bundle — 1×2×24, 10 Board Pack

10 BoardsDovetail-Ready

Ten cherry boards at the compact 1×2×24 size — ideal for dovetailed boxes, watch cases, and end-grain cutting board accents. The S2S surfacing delivers one clean face, and actual thickness holds at 15/16″. One buyer building an end-grain cutting board found all boards straight and accurate, while another noted that a single board had a large indent that planing did not fully remove — a reminder that “hit or miss” means you may get one piece that needs extra work.

The cherry darkens beautifully with exposure, shifting from pinkish-tan to a rich reddish-brown over a few months. Buyers praise the fast shipping and clean cuts. A reviewer using cherry for a cribbage board praised the wood for taking crisp routed lines without tear-out.

If you need a bulk supply of narrow cherry stock for small joinery projects, this ten-pack delivers high board count per dollar. It also matches well with the ash from the number-one pick for two-tone boxes or cutting boards.

Why it’s great

  • Ten boards for budget-friendly per-board cost
  • Cherry darkens beautifully with age
  • Clean edges for dovetail joinery

Good to know

  • One board occasionally has an indent
  • Narrow width limits project options
Budget Champion

7. Barrington Hardwoods Walnut Lumber — 3/4×2×12, 4 Pieces

S2S StripsKiln Dried

Four pieces of commercial-grade walnut, sanded on two sides to a consistent ¾″ thickness. The boards measure 2″ wide by 12″ long, making them suited for small repairs, accent strips, and knife scales. One buyer used a single board to replace a missing piece on an 1880s Eastlake mirror — the walnut matched the antique patina after a light stain. Another turned a full set into beautiful cutting boards, noting that the wood arrived ready to use with no warping or cupping.

The “commercial grade” rating means you may see minor color variation or small defects, but every review emphasizes how square and flat the boards are. Surfaced two sides means the faces are smooth; the edges will need a pass through the jointer if you need glue-ready joints. The straight grain is consistent across all four pieces.

This is the entry-level option for anyone who wants to test Barrington Hardwoods before committing to larger bundles. At this price point, the per-board cost is minimal, and the walnut quality punches above its weight class. Perfect for small jewelry boxes, decorative inlays, or practice pieces before cutting into expensive wide stock.

Why it’s great

  • Affordable entry point for walnut
  • Square and flat right out of the box
  • Rich brown grain matches walnut patina

Good to know

  • Boards are only 12″ long
  • Edges need jointing for glue-ups

FAQ

What does “hit or miss” thickness mean for ash lumber?
It means the boards are surfaced to a target thickness but may vary by a few 64ths of an inch board to board. For most furniture projects, you will still run the boards through a planer to achieve a consistent final dimension. The term is not a negative — it simply signals that you should not expect S4S precision straight from the bundle.
Can I use ash for cutting boards if it is kiln dried?
Yes. Ash has a Janka hardness of about 1,320 — harder than black walnut but softer than hard maple. Its open grain absorbs moisture faster than maple, but a properly applied food-safe oil finish seals it well. Many woodworkers use ash for cutting boards specifically because the grain pattern is more pronounced than maple.
Why do some ash boards arrive looking gray or dull?
Freshly milled ash often appears pale or grayish due to oxidation and handling. Sanding or planing off the top surface exposes the creamy white sapwood and light brown heartwood. UV exposure over a few days will also brighten the color. This is normal and not a defect.
Is 3/4″ ash strong enough for chair legs or table legs?
For light side tables or small chairs, 3/4″ ash is acceptable if the joinery is robust (mortise and tenon). For dining tables or heavy-use chairs, 4/4 (one-inch nominal, actual 13/16″ to 7/8″) stock is safer. Ash’s shock resistance is excellent, but thin sections under 3/4″ risk splitting under lateral load.

Final Thoughts: The Verdict

For most woodworkers, the ash wood lumber winner is the Forest 2 Home 1×6×24 six-pack because it delivers reliably flat, kiln-dried boards at a competitive per-board-foot price. If you need turning stock for the lathe, grab the Barrington Hardwoods White Ash Turning Blanks. And for mixed-species projects that call for walnut, cherry, and maple accents, nothing beats the Exotic Wood Zone 15-board bundle.
