Riving knife! That's the best method. I've heard it said that it's impossible to have kickback with a riving knife.
Other things to consider:
Having a fence parallel to the blade. When it's not parallel, you might pinch the blade and cause the workpiece to fly back at you.
Don't rip boards in half. If you have a six inch board that you cut ...
Anything tool that rotates is generally something to avoid using gloves with. Tools to definitely avoid glove use for incude:
Circular saws (including table saws, miter saws, and radial arm saws)
The list goes on...
Gloves can give you a false sense of security. They will do little to protect you from a cut, ...
I use a Stanley Panel Carry (Model 93-300). It is about $7.00 on Amazon or at Home Depot.
For cutting panels, the best way is to get a sheet of foam insulation, and lay it on the ground and put the panel on top of it. Cut through the panel into the foam.
There are commercial handles that are supposed to make carrying plywood easier, but they're not inexpensive.
The simplest way I've carried sheet goods is with a loop of rope caught on the corners.
Is this considered safe?
It can be done safely. A tall fence, featherboards, and good push stick make a big difference. Not everyone takes the time to set all that up, though, so it's worth pointing out that (like any TS operation) it can also be done unsafely.
If so, what are the rules of resawing on a table saw?
tall fence: The big ...
Is working MDF bad for your health?
Yes but only if you are ignorant of your tools and materials.
It certainly can be. However the answer of "Yes" is misleading as the concerns surrounding MDF are more than just the potential presence of hazards such as the release formaldehyde. Working MDF creates dust particles much like any other wood. It is true ...
Kickback can occur when the back of the blade gets pinched in the kerf, when a piece of wood is pinched between the blade and fence, or when a piece of wood is lifted off the table.
As others have mentioned, a riving knife, anti-kickback pawls, and fence-mounted featherboards help protect against kickback.
If using a table-mounted ...
A "climb cut" is called such because the workpiece wants to "climb" over the blade--or, if the workpiece is fixed, the blade wants to "climb" over the workpiece. Where do you think Galoob got the idea for THE ANIMAL monster truck? Some guy trying to make a deep climb cut with a rip blade on a circular saw, no doubt.
Some people use a very shallow climb ...
There are certainly oils and other flammable liquids, plus possible electrical malfunction, so I would indeed suggest an ABC, preferably a larger one. Remember that you always aim an extinguisher at the base of a fire, not at the flames.
However, it's important to note: Unless the fire is one you are sure you can put out quickly and easily, the most ...
PVC is commonly used in dust collection systems. Typically for longer runs you should use 6" or larger pipe, regardless of the material. If you're using PVC, the larger, less expensive pipe is commonly available as sewer drain pipe.
As of May 2015, there have been no known fires caused by a static discharge in a PVC pipe from a dust collection system.
It varies by model, check the manual online for the model you're looking at. Generally the shortest recommended length is also the distance between the center of the rollers.
Basically, you never want the possibility of a piece of wood being 'stuck' under the cutter head but not being held down by a roller.
You can counteract this limitation with some ...
If you call up Freud and ask, they'll tell you that you want one full tooth to clear the top of the wood, but no more.
There are a couple of reasons for that recommendation- first is safety. A tooth that clears the surface on the up swing then re-enters on the down swing may not follow the same planar path due to harmonics and vibration related physics. A ...
Technically there's no minimum length you can send through a thickness planer if you 'cheat'. There are various tricks that allow planing of material both too thin and too short and they can work well.
For short stock you use outriggers, pieces of scrap wood glued to either side of the board you want to plane. Like this:
As a secondary safety measure to @dfife's excellent riving knife suggestion, anti-kickback pawls are another option.
Generally they install on the riving knife itself, and are spring loaded to stay in contact with the workpiece. Think of it as a one-way clutch for your lumber.
Note that I've had issues with these scratching softwoods like pine, so I only ...
The 4x4 posts used for the legs support virtually "infinite" weight longitudinally. Now, of course, given a naive design, each leg would only transmit force onto one 4x2 beam (which are then maybe nailed together with some kind of ledge or so), which isn't optimal. You most definitely want to connect the beams with a dovetail batten or a similar construct ...
Short answer: always wear a properly-fitted, high-efficiency respirator so you can reduce your chances of developing respiratory problems or certain types of cancer of the respiratory system later in life.
There are many levels of protection when it comes to filtering the air you breathe, from cheap paper masks that provide very little protection, to ...
I've a dust mask but I wonder if it worth wearing it when working on
pine wood. I do wear it when working a piece oak or beech.
First off, let's be clear: a disposable paper dust mask may be slightly better than nothing, but even a fancy $5 disposable P100 dust mask with a breathing valve will not perform as well as a properly-fitted respirator with ...
A 12" miter saw blade of the ilk normally found on a miter saw or cut-off saw looks like this:
The teeth on the saw blade are carbide material that is very hard. You will not want to take a file to those teeth as they will very quickly kill your file.
This type of saw blade has gained huge popularity in recent years because the hardness of the carbide ...
When determining the load bearing capacity of any structure, you'll need to take into account several different factors:
Maximum allowable bending stress
Column compressive and buckling strengths
For calculating deflection, @rob's suggestion of using the Sagulator is a good start. You don't need to have an in-depth grasp of all the ...
Under what condition, if any, can I reuse the rags?
I just throw my finishing rags away after using them; I can't think of any case in which you'd want to reuse them. It would probably cost more to try to clean them than it would to get a new rag.
What is the process for prepping these rags for safe disposal?
Spread each one out flat to dry on the ...
I think the word 'safe' here might be relative. Just like modern cars are safe, when driven on the road, and obeying traffic laws. I think in this case the answer is a profound NO.
Table saws are 'safe' when used for cutting wood that is against the table, and the stop, preferably using push sticks and a riving knife. I see none of those things going on ...
These can usually be easy to come by. Plenty of businesses view them as scrap and are glad for you taking them away. Pallets are a favorite among up-cyclers as a (usually) free source of material and its unique look and feel. That being said there are several points to consider when collecting pallet wood.
There are some basic things ...
No, SawStop is the only table saw currently available for purchase (as of Apr 2015) which features a flesh-triggered active safety device.
However, on March 16, 2015, Bosch announced a jobsite table saw featuring an active safety system they call REAXX. Although the saw is not yet available for purchase, the press release notes, "The Bosch REAXX Jobsite ...
A riving knife goes up and down with the blade, so it's always the same distance from the back of the blade.
One person on the Fine Woodworking forums made a nice illustration:
A splitter does not raise and lower with the blade, so as you lower the blade, the gap between the blade and splitter increases. This allows for a greater chance of ...
There are panel carriers which range from inexpensive at less than $10 to rather pricey at around $50. You can also use the rope loop method as suggested by TX Turner.
Personally, I try to avoid lifting 4'x8' sheets thicker than 1/2" by myself. Instead I slide or drag them onto the cart at the store, then slide or drag them onto the car's luggage rack (or ...
The bit they are using in that picture has a bearing on the top part that is sticking out of the table (which is actually the bottom of the bit, because routers are inverted in a router table). Bits with bearings like that are safe to operate without a fence, because the bearing spins, acting as a guide as the stock is pushed along the bit. It doesn't matter ...
OSHA defines what noise levels warrant hearing protection to assure safe working conditions. Excessive noise is generally defined as exposure to 85 or more decibels of sound over an 8 hour period. But if the ambient noise exceeds those levels, the amount of time until damage can occur will decrease.
Hearing protectors must be tested and approved by the ...
Wear safely glasses or a full-face mask every time you turn, no exceptions.
Dust mask or respirator advisable normally but essential when sanding.
Tie long hair back.
No long sleeves.
Take off rings, bangles, bracelets or a wristwatch.
Consider whether it would be safer to remove any necklace, crucifix or medallion worn around the neck.
Although there are many instances in which you need to remove a standard or modular table saw blade guard, most cuts can be made with a riving knife installed. However, there are a few operations for which you must (or should) remove the riving knife:
Raising the blade through a workpiece (e.g., when cutting the slot for a crosscut sled or zero-clearance ...
The hook angle refers to the angle at which the teeth will engage the material being cut. A high or positive hook angle means the outermost tip of each tooth will engage very aggressively, whereas a low or negative hook angle causes each tooth to take a less aggressive bite.
How do I choose a blade based on hook angle?
Use a blade with a negative ...
