Jeffery – As Rob explained things we had the RPM measurements running on that meter, and had to watch our video playback to evaluate the numbers (no recording of the numbers digitally). So we tried to take the average no load speed watching the video play back. Is it perfect? No….is a 10% difference a big deal? In this application I doubt it. If we were a full blown testing lab we’d have the data recorded digitally and take full blow averages, but alas we are not.
Bosch’s 4100-09 work site table saw is a sure win. Bosch never fails to impress us, and this table saw is no exception. It’s a 10 in. saw with a 25 in (right) rip capacity and a 47 degree left bevel. This Bosch table saw is powered by a 15A motor that reaches top speeds up to 3,650 RPM. Another feature we appreciate: its constant response circuits which continuously adapt the speed under load, giving you a continuous blade speed.
Safety is a prime concern for Bosch. From the SquareLock Rip Fence through to the patented SmartGuard System to lessen any chance of kickback, your security and comfort is taken care of. The blade guard and riving knife are quick-release. This takes away any excuse for not putting the guard back in place because it would be too much trouble, something that’s an accident waiting to happen.
By the late 18th century, a new tool had been created that would eventually have the sawyers out of work: the circular saw. These early rotating saws were powered by a range of different forces, often including running water or wind, and sometimes driven by animal power. By the early 1800s, the sawmill was replacing the saw pit and its hardworking manual sawyers.
Standard table saws are also called contractor table saws, even if they're really intended for the home do-it-yourselfer. These table saws have open, fixed legs, and they take up more space than a portable or benchtop table saw. They're also heavier – weighing as much as 200 to 300 pounds. On the plus side, their tables are often larger, making it easier to cut 4 by 8-foot panels of plywood or sheetrock. Prices for contractor saws range from around $600 to nearly $2,000.
The price is acceptable. One cannot say it’s a cheap piece of equipment because it’s not. But, the high quality of production and a great deal of precision justify the somewhat premium price. If you’re a devoted professional, the price shouldn’t be much of an issue for you. The only downside many people reported is the quality control within the company. Many models came with broken or missing parts.
While DeWALT’s DW744X is the only model here without wheels, the saw is otherwise well appointed. It’s got a unique rip fence design: instead of sliding along front and back rails, the fence is fixed to them. To change rip fence settings, you extend the rails out on rack-and-pinion gears. The design keeps the fence parallel to the blade/miter slots and prevents it from deflecting if pushed laterally. A red hairline cursor makes fence settings easy to read, and it passed my ripping tests with flying colors.
There’s also a secondary flip-down fence which allows you to make narrower rips. We love this feature, which should really become industry standard in the near future. It helps you make smaller cuts without needing to have your fingers close to the blade. Reviewers loved it, and said they found themselves using the feature much more frequently than they’d anticipated.
If you’re a professional looking for a great table saw for the worksite, you’ll love the features and performance of the DEWALT DWE7480. Equipped with the Site-Pro Modular Guarding System has a rack and pinion telescoping fence rail that will allow you to make fast, smooth and accurate adjustments. This is the perfect table saw for cutting larger shelving and trim easily. With a 15 AMP 4800 rpm motor, you will go through all types of wood, even hardwood, with ease.
The fence on a table saw is one of its defining features and allows for precise, square, and repeatable cuts. Not all fences are equal though and a poorly built fence is a deal-breaker, in my opinion. Not only will a poorly built and implemented fence affect the quality of your cuts, but a fence that moves or is not square to the blade can cause your material to bind and kickback.
6. Clamp rip fence to check if it holds securely at front and rear. If rear is not clamped securely, un- clamp fence and turn rear clamp adjustment screw 6 clockwise for increased clamping. Try clamping the fence to verify if it self aligns and clamps tightly at the front and rear. Overtightening of the rear clamp adjustment screw 6 will cause the rip fence to be non-self aligning (Fig. 23). Overtightening may cause friction or “chatter” when fence is moved side to side.
