How Quartersawn White Oak Is Sawn

If this is your first visit, be sure to check out the FAQ by clicking the link above. Pieces of lumber that are not only surfaced, but also machined to produce a specific cross sectional shape are classified as worked lumber or pattern lumber. There’s a reason people use bandsaws for resawing and a frame saw is the closest thing to that. This works great for oak, as you can get practically every board out of the log with a lovely ‘quarter sawn’ figure to it. The amount of time it takes is approximately the same as the time needed for the lumber mill to reset.

The reason for the extra charges is that I have to hand load the pieces into and out of the kiln; lifting this extreme wood is not easy. The crazy thing is that back then I couldn’t find solid information on lumber thicknesses anywhere and when I referred to the NHLA (National Hardwood Lumber Association) guide, the thicknesses didn’t match up with what I was finding from hardwood producers.

There is several things to consider when deciding whether to have your logs sawn on site or transported to my location. On the second cut, the mill uses the surface you just created to support and guide it. If the log is to be sawed into lumber or beams, the second cut is taken on the bottom of the log. A blade guard assembly that includes a splitter and an anti-kickback pawl is standard equipment with every table saw.

Sticker spacing varies depending on the species and thickness of the lumber being dried; a conservative spacing scheme would be every 12”, though usually 16” or 24” spacing can be safely used on thicker pieces. At some point down the road, I’d like to build a very sturdy overhead beam rigged with block and tackle to lift and place the logs by hand. With the chainsaw lumber-maker, the carpenter has unlimited choices of species and size of boards for his projects. Though the work is intensive, the satisfaction of sawing my own custom lumber makes the hard labor well worth the effort.

I have tried this on much larger pieces and you really need a frame saw (the one with the blade in the center). He has a WoodMizer LT40 (for cuts up to 24 inches), and two chainsaw mills for the really large or specialized logs. The sawyer must assess each log as he rapidly rolls it onto the carriage to position it so it yields the highest value lumber possible. It is far more prone to vibration and is harder on the saw and I will repeat myself and say, only the larger chainsaws should use this full skip chain. Also called bastard cut, the face of a rift sawn boards looks similar to quarter sawn ones, but the straight grain is more widely spaced as shown to the left.

To achieve this lumber is built into stacks in a way that allows good air flow over and under both faces of each board. First, the Atlantic white cedar I use for boat lumber is more than twice as thick as I need for planking and deck material. The proper mix of log sizes entering the sawmill can greatly increase efficiency of production through the mill. In terms of length of logs, my mill can handle anything from 4 to 21 feet in length. Many of the portable saw mills that are available to buy have parts that wear out, so keep an eye on this, especially if you opt for a used one. This saw is comfortable to use, and cuts faster than I imagined any, man-powered saw to saw lumber

A sawmill will cut a log in three main ways that yield lumber with different characteristics: plainsawn, quartersawn, and riftsawn. Built for cutting lumber in long and straight lines, saw mills do the most professional job. You honestly are better off finding someone local who will cut for you for half the wood, instead of turning half the wood into sawdust by using a chainsaw.

Always make push sticks out of plywood, not lumber that could split and fall apart while you’re pushing. This device, known as a chainsaw lumber-maker, will mill through any tree, no matter how large or tough, making boards of any length or thickness. Clearly these guys are pretty skilled but I’m sure it could be learned with practice and even rough sawn boards could be run through a plane/thicknesser if you needed a more accurate finsihed product. The saw chain needs to be kept sharp, and it will be over seven feet long, so chain sharpening is the most tedious part of lumber-making.

Band saws produce a cut that’s not very smooth and a little bit wavy; and the waves get more pronounced with denser woods. Plus blade tips were the shape of a swage tooth wide band so they cut straight and carry the chip out, Prototype was Stellite 12 on a high tension backer. This actually saves you considerable work over a period of time, as you are not taking lumber and stacking it, just to have to move it again.

At the trim saw, the trimmerman” determines to which length the boards will be cut to maximize their value, and inputs a series of commands to a computer that controls when the trim saw will lower and cut the boards to length. Both hardwood and softwood lumber pieces are graded according to the number and size of defects in the wood. If you cut your own trees and prepare the logs for milling, there are still savings to be had over commercial lumber. Keep the fasteners away from the edge where they might come in contact with the saw blade. The quality of the log, the species and the dimensions all play a part, as does how it is sawn and dried.

After one more turn, we’re about to reduce our once circular log to a rectangular beam. Once the initial cut is made, the top surface of the log will be flat, and the starter board won’t be needed again until a new log is started. I wish I had taken more notes as to exact times it took to mill certain boards, fuel usage, sharpening, etc. My mileage charges can be found at: Pricebook I charge by the round trip mile for travel with the mill and/or trailer. In most instances, simply storing project lumber at a targeted humidity level is the best option to ensure it will be at the correct EMC when building time comes.

After cutting the lumber and it drops into the lumber pile, you must wait about 10 seconds for the freshly cut log to disappear before it is added as 10 sawn logs. Bandsaw resawing can be difficult for beginners to master, but a properly tuned bandsaw can greatly improve the process. They are truly artists at their work which includes the precise grinding of saw teeth, re-tipping, benching and leveling the saws. Build your own lumber rack in minutes with this ShelterLogic firewood lumber rack bracket kit.

A bandsaw guard is nearly always removed for resawing operations, because if the material is more than a few inches tall, a guard will not protect the operator and at the same time will increase the amount of blade which is unsupported, making drift more likely. I see it as a gateway skill that any hand tool woodworker should be able to easily learn.

Weighing in at about 1,800 pounds, the mill is as easy to tow as any 16′ trailer and only takes about ten minutes to set up at a customer’s site. If three or four ten-foot starter boards are made, they can be set end to end and a 30- or 40-foot tree can be milled, providing lumber long enough to make beams. When I’m sawing construction lumber, I run the flitches through my edger to the width of lumber I want. So now is the time to prepare if you want to make cutting frozen lumber much easier this year. Cut all your materials, from drywall to ceramic tile to steel, with this circular saw. Allow the saw to run a few seconds to get to full speed before beginning your to saw lumber

I’ve also added a closeup from another instructable below That said, I definitely agree about the bandsaw being the right tool for the job. It attaches to your chain saw bar by drilling two holes, comes supplied with 3/8 and325 sprockets, weighs under 3 lbs and fits all chain saws. A small mill such as this would be the center of many rural communities in wood-exporting regions such as the Baltic countries and Canada The output of such mills would be quite low, perhaps only 500 boards per day. The only way 1″ thick rough-cut hardwood lumber can plane out completely to 13/16″ or 3/4″ thick is to skip the flattening and just plane the lumber.

With the HEADCUTTER the operator can easily guide the chain saw to follow a snap-line or scribed arc making it the perfect framer’s” tool for gang cutting ganged lumber, beams placed on edge, structural insulated roof panels, etc. In my experience, 4/4 hardwood lumber cut at 1″ is too thin to consistently produce flattened and planed lumber at 13/16″ thick and will even have trouble producing 3/4″ thick unless the boards are very flat.

I am looking for the highest quality thin curf radial saw blades you have around0625in. There can be symmetry to saving urban lumber: a piece of furniture made for a grandchild could well incorporate the branch that held his father’s tire swing. That way I can easily pick the piles up with my tractor and move them to where they will be sawn into firewood. The HADDON LUMBERMAKER is the perfect tool to turn any chainsaw into a hand held lumbermill. The handle on the shoe shape gives you a better grip for more control over the wood and reduces the chances of your hand slipping off. This can be as simple as moving the lumber stack from a garage or shed into a heated basement indoors.

The teeth on most high-quality saw blades are thick carbide tips that have been fused (or brazed) to the steel blade plate. Later, we hope to get a sponsor for a commercially available chainsaw mill like the Granberg 36″ model so we can compare against our DIY model. Waste material from the trim saw falls through a drop gate to the outside slasher conveyor and, along with sawdust and other scrap material, is fed into a processing facility that chips and pulverizes it into premium quality soil mulch. Live trees have very high moisture levels and this can double the weight of the lumber.

It’s also important to understand that the use of axes, adzes, hand saws, manually-operated pit saws, mechanical pit saws, and circular saws would have been used in overlapping eras. Portable sawmills have gained popularity for the convenience of bringing the sawmill to the logs and milling lumber in remote locations. One of the last items on my bucket list, is to build a small log cabin, from planted pines, on our property. Take a piece of plain sawn wood and on the end of the board, mark out the quartersawn pieces you can cut out.
