There are currently no dust-control regulations for U.S. table saw, and they typically have minimal dust collection. We are now increasingly aware of the health hazards of dust to woodworkers. Classified as a carcinogen, wood dust is responsible for a significant increase in respiratory diseases and nasal cancers as compared to the general population.
U.S.-style cabinet saws, at best, have what I call chip containment and inefficient dust collection. On both cabinet saws and contractor’s saws the majority of dust and chips are thrown below the table by the front teeth of the saw blade. There is no efficient way on either type of U.S. saw to direct the dust and chips to a dust collector. Some newer U.S. table saws and most portable table saws do have a better system for collecting sawdust. Like the European table saw, the portion of the blade below the table is shrouded and then ported to an external connection port. The throwing force of the blade directs the sawdust toward the port, which is not only efficient but requires less suction.
European table saws also have a dust port above the table on the blade cover. No U.S.-style saws offer dust collection on the blade guard. Some after-market table saw blade covers offer this option although it does little good unless you have good dust collection below the table first. For effective protection from dust particles, a table saw needs dust ports above and below the saw.
Table Saw Rip Fences
By now you may not be surprised that there are also regulations in Europe that pertain to the rip fence. The regulations say the rip fence must offer two positions and be adjustable in length. There is a high position (50-90mm) and a low position (5-15mm). If you have seen a Delta UniFence you have seen a European-style rip fence. The high fence position, the one that U.S. table saws typically use, is for tall or wide work. The low position is for narrow work, allowing room for you to push the work through and still use the blade cover. European table saws have primarily right-
tilting blades and the fence in the low position allows the blade to be tilted toward the fence without coming into contact with it. With an adjustable-length fence, the fence can be made shorter, which is especially handy for ripping short pieces.
The Biesemeyer-style fence has become the standard for table saws in the United States. European fences generally seem less rigid when compared to the Biesemeyer-style fence. An extremely rigid fence is advantageous when cutting large panels. However because European table saws have depended more on the sliding table, not the fence, for accuracy when cutting sheet goods and large panels, the rigidity of the fence is not an issue.
U.S. table saws use a miter gauge for crosscutting. The miter gauge is limited in its capacity and accuracy. We have had to resort to shopmade and aftermarket solutions and additional machinery to make up for the shortcomings of the miter gauge. Nearly all professional woodworkers I know who have a U.S. table saw have had to add a crosscut sled for cutting wide and heavy panels. In addition, I have found that aftermarket sliding tables are typically not sufficiently accurate and take up a lot of space. The addition of a miter saw in the woodshop has replaced the less accurate radial arm saw, but the miter saw is still limited in its capacity to cut wide boards. That leaves the necessity of using crosscut sleds. I had a large array for my U.S. saws.
European table saws commonly use a sliding table for crosscutting. Early U.S. table saws had this feature. A sliding table carries work of all sizes and weights. The sliding table is guided close to the saw blade resulting in increased accuracy. Additional tables and fences of all sizes can be attached to the sliding table and removed. I believe it is the most important component that is missing from U.S. table saws. The DeWalt hybrid (also made for the European market) and the Jet Supersaw are U.S. table saws that do incorporate a small sliding table as an option. Grizzly is starting to offer European-style table saws with sliding tables on some of their saws.
When ripping and crosscutting on a European sliding table saw, the user stands to the front left side of the stationary table for most cuts. This means that you are operating the saw similarly to how you would feed a workpiece on a router table. It takes a little getting used to, but once you become accustomed to this stance you will find it feels much safer and you have more control of the workpiece – especially after the cut. The sliding table is frequently used for ripping as well. For example a waney-edged board can be held on the sliding table for making a straight rip. There are also sliding table fence accessories that allow parallel ripping on the sliding table. A sliding table has at least one miter-type slot for other accessories such as hold-downs.
We have come to expect dado-cutting capacity on U.S. table saws, and so our saws offer arbors that can accept the standard 1 3/16″ stacked dado. Dado cutting is in reality a shaping cut and European standards prohibit dado cutting on table saws based on the belief that it can be a dangerous operation because it is difficult to guard. It is better done with a shaper or router. Because the U.S. market has become used to having dado capacity on table saws European saws that are marketed in the U.S. now have adapted these saws for dado cutting and now offer this feature to the U.S. market.
Scoring is making
a shallow precut with a small-diameter blade rotating opposite to the main saw blade. Scoring eliminates tear-out and is especially desirable when cutting veneered sheet goods and products such as Melamine. The solid wood woodworker can find it useful for clean crosscutting. This built-in feature is common on large commercial U.S. panel saws and is offered on most European table saws. Scoring can be done on a European saw, but no U.S. saw other than panel saws offer this as an option.
U.S. table saws allow up to a 3/4″ opening on throat plates. The size of this opening is problematic because narrow pieces of wood can drop into the opening and be thrown back out or can be stuck and thereby tempt the operator to reach for the stuck piece when the blade is spinning.
European table saws allow no greater than a 1/2″ opening on throat plates and a 1/8″ space on the fence side thereby minimizing the hazard of narrow pieces becoming lost or lodged in the spaces.
In Europe space and energy are at a premium. That fact has driven the design and manufacture of some efficient table saw combination machines. Combination woodworking machines are common in Europe, from a table saw/shaper combination to a full combo-sliding table saw, shaper, jointer, planer and mortiser with three motors. These combination machines are not like a ShopSmith that is lathe-based. These combination machines are table saw-based and no change in tools takes more than a minute.
There are many advantages for space, energy and dust collection. A full combination machine takes up no more space than a U.S. cabinet saw with typical extension tables. As an added bonus, the shaper gets full use of the table saw’s sliding table.
Mobility is as necessary on European tools as it is here for the garage and basement woodworker. The difference is that European tools typically have two wheels on one end and a yoke that accepts a wheeled lever on the other. U.S. table saw manufacturers typically install the machine on a mobile base. The PM2000 has a unique solution that allows the table saw to sit on its cast base until it is jacked up on its internal wheels.
Table Saw Types: Contractor Saws and European Site Saws
Contractor’s saws were originally developed for the housing boom after WWII for building contractors. The motor was put on the outside of the saw with quick-release holders so it could be removed for easier transport. This table saw was never intended to be used inside a woodshop where an open back and bottom and a motor extended to the rear are not necessarily desirable features. In Europe there is a saw for the construction jobsite called a site saw of all things. Typically it has at least a 12″ blade that doesn’t tilt. Primarily designed for ripping, it has a stand, usually with foldable legs and a foldable outfeed table. Because it is intended for outside use, the saw is not required to have dust collection. The saw assembly is enclosed below the table and there is a chute for the sawdust below the table.
Cabinet-style Table Saws
European and U.S. cabinet saws both have a large cast iron top mounted on a steel cabinet-style base. The U.S. style has been pretty much based on a Delta Unisaw design which dates back to 1939.
Generally there is a difference in the way that the saw assemblies work. Both the U.S. and European assemblies are mounted to trunnions at the front and back of the cabinet; these allow for tilting. For adjusting blade height, U.S. saws incorporate an arbor assembly that swings up in an arc independent of the carriage assembly. On the majority of European saws, the whole assembly travels vertically and tilts. I don’t see any particular advantage either way except there is less complication for the manufacturer when designing a riving-knife assembly on the European saw.
Right Tilt, Left Tilt
An ideal table saw would allow the user to choose either a right-tilting or a left-tilting blade position. However, since this situation exists only in a limited market the questions you might have are: “Which is better?” and “Does it make a difference?”
Many U.S. saws have moved to having a left-tilting blade while the typical European saw has a right-tilting blade. As a rule, you will be safer and will get cleaner bevel cuts by tilting the blade away from the workpiece being cut. When ripping bevels it is better to have the blade tilt to the left because the fence is on the right. With a miter slot on either side of the blade on U.S. saws, the user has the option of using whichever slot is appropriate for blade tilt when crosscutting bevels. Because European saws have a sliding table affixed to the left side of the saw, having a right tilting blades works best for crosscutting bevels. Other than when making bevel cuts, the blade tilt is not particularly significant.
(The two contradictions are the DeWalt 746 and the Jet Supersaw which, when outfitted with a sliding table to the left of the blade, still have a left-tilting blade.)
European table saws are generally more expensive than U.S. saws, depending on the number of features or additions on the saw. European saws have many desirable built-in features that woodworkers later add to their U.S. saws to improve them, including sliding tables, improved guarding and superior dust collection to name a few. Once you factor in these extra features, the price difference between European- and U.S.-style saws is reduced, and the European saws look more competitive. For me, after spending lots of money on aftermarket accessories and time building shop jigs for the table saw the price differences did not seem so substantial. Additionally, the increased accuracy and safety of the European saws outweighed the initial cost and have ended up paying worthy dividends.
Your budget, frequency of table-saw use, purposes for which you use the saw, and your expectations about the performance of the machine are all factors that weigh into your decision about which table saw to use. Fortunately for you, finding and using a table saw that suits your needs and purposes is very possible in both the U.S.-style saw market or the Euro-style saw market. Hopefully this article has provided you with some information that will enable you to make an active and informed choice so that you will be a safe and effective using the table saw of your choice.
