A table saw is probably the most common woodworking tool in a woodworking shop. Statistically, it is also probably the most dangerous thing, because sawdust causes more destructive damage than any other woodworking machine if you use a table saw.
Does this mean that table time cannot be used safely? Not. By taking the right precautions, a carpenter can greatly reduce the risk of injury with a table saw. Here are twelve safety tips every carpenter should consider before using a table saw:
When using power tools, it is mandatory to wear suitable safety equipment. The carpenter should always wear eye and hearing protection, but appropriate clothing should also be considered. Loose clothing, ties, and jewellery are dangers that should be avoided when using a table saw.
When using a table saw, keep the table and surrounding area clean, free from cuts and excess sawdust. All of these can hinder or interfere with the carpenter’s ability to make safe and clean cuts. A loose part can be a bullet if it comes into contact with a moving blade.
Before working with a table saw, always check the safety devices on your table saw to make sure it is set up correctly and working correctly. The blade guard, blade and counter-clockwise blades are designed to protect the carpenter and must be properly adjusted before using the power supply.
Eliminate large stocks, eg. Filled with a piece of plywood, set up a large table or pad to support the buttocks. Using these tools cuts the most stable parts and makes cutting easier.
The carpenter should always turn off the saw before changing the table saw or other internal settings. This prevents the saw from accidentally turning it on while working at table time.
When preparing to start the saw, the carpenter must check that the saw blade can rotate freely and does not get caught. When the engine is running, the knife must be full before being cut.
Standing in front of the table saw, the carpenter should adopt a good, stable posture with a wide base to maintain balance. Also, one should not stand directly in front of the blade so that the rod does not pull into the body in the event of a back kick, but slips along the centre of the operator.
The operator does not have to remove or adjust the door or blades while the blade is still moving. Instead, wait for the blade to come to a complete stop before curing or settling.
Always use the correct zero-height entries when using a table saw. Proper use should also be done when using a stackable cube. Without inserting the saw blade, the tree can fall into the saw box and become a projector.
When using a table saw, the carpenter should never attempt to cut by hand. Instead, use a fence or multimeter to check inventory. Note, however, that the guide and multimeter should never be used together as the short end of the paper may stick to the guide.
Before cutting, the carpenter should visually inspect the cutting board for foreign objects such as screws, nails, staples, or even loose wood. If in contact with a rotating blade, any of them can detach and become a dangerous projectile. A specially designed metal detector is perfect for checking hidden seals in the warehouse, especially when working with recycled materials.
If the cutting board is less than 15cm from the width of the blade, you need to use a push rod to cut the wooden board through the blade. This protects the carpenter’s fingers from the steel. You can build good pushrods in a shop or buy them from any good lumberjack.
The irony is that some top-quality table chairs, usually cast iron for tabletops, must be rusted. Cast iron is the gold standard for large table chairs, where the high weight ensures durability impossible with the lightest aluminium or brushed aluminium used in portable chairs. Cast iron offers an extremely durable saw, but the downside is that it is exposed to rust, especially in humid climates such as coastal areas.
This can be especially problematic for saws that are used infrequently and are not regularly maintained. If your cast iron table saw has not been used for several years and enough rust has built upon the table, the rust can usually be removed and prevent it from coming back. There are dozens of recommended methods for this, which sometimes seem as if almost every carpenter has a method they can swear by.
No matter how much rust has turned up, you don’t know how much it can cure before you try it. Here are some good ways to remove rust from a table saw.
One of the most common methods of removing rust from a table saw is the one you shouldn’t use at all: smooth sandpaper. Do not under any circumstances attach the table to sandpaper, sander or hand sandpaper. Some think that steel wool or very fine sandpaper, such as 800 or 1500 dry sandpaper, can be used to remove rust and polish a table saw, but steel wool or sandpaper leaves small and light scratches on the metal. makes it prone to moisture build-up and will cause more rust in the future.
Instead, use a synthetic sanding pad with some type of oil to clean the saw table. The ideal is a Scottish British block or similar for cleaning synthetic fibres.
The synthetic fibre straightening block provides enough wear to remove rust from cast iron without scratching the metal, but some type of lubricant is required. Mineral oil is an excellent option. Apply enough oil to the table before drying, but be careful not to overdo it as you will need to dry the oil after cleaning.
Thoroughly clean the metal table in a circular motion and rock it back and forth until all rust is removed. Then wipe off all traces of oil with a clean cloth until the metal table is completely dry. Metal has an invisible layer of oil that is dry to the touch but protects the metal from moisture that causes oxidation.
For a thicker crust, you can use an occasional brush to help with cleaning. Put the bottom of the sand in the cleaner and get started.
Some people use WD-40 instead of mineral oil, which works well although it evaporates faster than mineral oil. If you decide to use the WD-40, apply it regularly to the entire saw table to lubricate it until you are done cleaning. Because this oil evaporates completely, corrosion can return a little faster with the WD-40 treatment.
A completely different idea, which has an advantage over extremely rusty cast iron plates, is the use of research jellies. To avoid installing cast iron, you should follow the instructions in the search box exactly, especially when it comes to rust removal. Gelatin is relatively aggressive in removing rust and must be properly removed to stop cleaning.
Once the rust has been removed, take steps to ensure that the rust does not return. There are a number of commercial products that not only protect the table from rust but also lubricate it so that items slide better on the table when cutting. Boeshield T-9 and Slipit are popular products, available online or primarily for sale, selling excellent woodworking materials.
