Factors to Consider Before Buying a Straight Flush Saw
Depending on the design of the tool and the type of blade attached to the unit, a straight flush saw is capable of making to make crosscuts—straight cuts across a board or rip cuts.
Some of the leading models may also be calibrated to make an assortment of bevel cuts.
While shopping for the right unit, there are some of the important considerations you need to make:
Almost all power saws are powered by electric current, either from a rechargeable battery or a direct connection to a power outlet. As such, you need to choose whether to go for the best cordless or corded straight flush saws.
Cordless circular saws are conveniently designed for use in areas where extension cords are difficult to use.
They also feature a smaller, lightweight and compact design for enhanced portability. Cordless saws often have a cutting range of between 5 3/8 and 6 1/2 inches.
Corded models, on the other hand, are more powerful and may be used on tougher applications like continuous woodcutting, masonry and steel cutting. While 7 1/4 inches corded straight flush saws are common, these tools are available in an array of size options.
Depending on what you will be using the saw to cut, you need to choose between two main straight flush saw blades;
- Carbide-tipped Saw Blades
These are costlier but have been proven to last longer than steel blades. Owing to their tough construction, carbide-tipped blades are suited for the more demanding applications, such as masonry and metal applications.
If this is your preferred blade type, it is you should opt for either the abrasive wheel or the tougher diamond blade options.
- Steel Straight Flush Saw Blades
The preference of steel blades by many craftsmen may be attributed to their affordability.
Steel blades need to be sharpened frequently for enhanced efficiency. With most steel saw blades, the teeth are known to dull rather fast. As such, they are only suited for mild and occasional cutting applications.
At high speeds, these tools can be rather difficult to control. Since you need high levels of precision for every project, you should go for a saw that is comparatively easy to handle.
With regards to design, go for designs with primary and secondary handles that are comfortable and conveniently positioned. The primary handle is the one that has a trigger positioned inside for regulating speed.
Different models come with one or two secondary handles to help- stabilize the tool as you cut. It isn’t a hybrid table saw (see top reviews) that has a sturdy base for stable cutting. Models with secondary handles will come in handy when working on such projects as ripping a piece of plywood.
Again, you need to ensure that the blade changing mechanism on your preferred morel is relatively easy to use. Whether it requires you to use a tool or is too-less, the mechanism should make it relatively easy and fast for you to change the blades.
Rather than going for the cheapest straight flush saws, it is advisable to try and get the best value for your money. It helps to get a quality product that may be used on an assortment of applications.
These are the adjustment options you should consider:
- Bevel Adjustment
Bevel adjustment settings allow you to tilt the saw to an angle of between 0° and 57°. However, this tilt range varies from one model to another.
In most straight flush saw models, bevel adjustment settings are situated at the front end of the tool and often have some sort of a locking mechanism.
- Depth Adjustment
The depth adjustment settings are often located on the back of the saw. In some models, it is a simple flange type mechanism. Others use a threaded type of bolt with a “T” on the end—often used on the best cordless straight flush saws.
These have indicators on them, indicating the preset cutting level. Most of the leading straight flush saw brands offer a range of between 0″ and 2.75″. Most power straight flush saws have a maximum depth of about 2.5″. Sure, it isn’t comparable to 3″-5″ depth capability of some of the greatest deep cut band saws, but with the size and portability of flush saws, the 2.5″ depth is already a good number.
For enhanced safety and precision, the leading models are designed to automatically apply an electric brake the moment you disengage the trigger.
Shoe Type and Material
The shoe on a power saw is the flat piece of metal that acts as the base; the part on which the tool rests. These are perfectly flat and can be made from steel, aluminum, magnesium or strong plastic material.
Aluminum, magnesium and plastic shoes are lighter as compared to steel shoes. However, steel plates are comparatively stronger than any of these other materials.in the more advanced saws, the shoe features guides that may be used to make rip cuts.
How to Use a Straight Flush Saw
Electric straight flush saws operate at high speeds and can be dangerous, if not operated as they should.
First things first, ensure that you always wear appropriate safety gear, including safety glasses before operating the tool. Safety precautions should be standard for any cutting task, whether you’re using a basic felling ax (best models reviewed here) or inside your woodshop using a top rated plunge router.
You also need to read and follow the safety instructions given by the manufacturer, often printed on its instruction manual.
Having taken all the necessary safety precautions, here are some of the tips to help you use a straight flush saw appropriately:
Regardless of the type of project you are working on, you first need to set up the piece you will be cutting and make the right adjustments on the tool. Support the material on a bench or between two strong sawhorses.
The overhanging section should be large enough to allow the cut piece to fall freely. Attempting to prop up the off-cut may cause the material to buckle or even bind the blade.
If this happens, the tool will generate a powerful kickback that may result in injuries. Once done, you should proceed to set the preferred blade depth on the tool.
Basically, you need to ensure that the lowest tooth on the blade is between 1/8 and ¼ inches below the workpiece. All adjustments on the power saw should be carried out while it is still unplugged.
Making Crosscuts with a Straight Flush Saw
To improve the precision of such a cut, mark the side of the material that will become waste. You should then position the blade such that it leaves a pencil-line thickness on the keep side.
Now support the front of the saw shoe on the workpiece while keeping the blade about an inch from the material. If corded, plug the saw to a power outlet and start it.
Allow the tool ample time to reach its optimal speed before engaging it on the material.
Once ready, push it steadily push the saw through the material that needs cutting. To make a 90-degree crosscut, you may use a speed square to guide the saw.
Making Rip Cuts with a Straight Flush Saw
Position large sheets of plywood across sawhorses and ensure that the setup supports both sides of the cut.
Clamp a plywood strip or any other straight workpiece at a distance to help guide the saw shoe as you make the cut.
While cutting, you need to walk alongside the plywood, while holding the straight flush saw cord to prevent it from getting snagged.
For narrow rips, keep the saw straight by holding the shoe with your free hand and bracing your forefinger on the edge of the material.
You may as well use a pair of locking pliers or a rip-fence accessory to help keep the saw straight as you cut.
