The Delta 16 inch scroll saw sits in a practical sweet spot for woodworkers who need precision without dedicating an entire wall to a larger machine. It offers enough throat capacity for signs, puzzles, fretwork, and intarsia, yet it remains compact enough for a garage bench or small studio.
If you have been comparing scroll saws, the Delta 40-694 and similar 16-inch models deserve attention because they combine a cast iron table, variable speed control, and tool-free blade changes in a package that feels approachable for beginners and capable for experienced makers. The details below cover what makes this size useful, how to set it up, which blades work best, and what to check before buying.
Why the Delta 16-Inch Scroll Saw Deserves a Closer Look
A 16-inch scroll saw measures the distance from the blade to the rear of the upper arm. That number determines how wide a workpiece can be before you need to rotate it or switch to a larger saw. In practical terms, 16 inches is a versatile middle ground: it handles most hobby projects, yet it does not take up as much room as an 18-inch or 20-inch machine.
Delta has a long history in woodworking machinery, and the 16-inch scroll saw reflects that heritage with a stable cast iron table and a straightforward design. It is not overloaded with digital screens or complicated electronics. Instead, it focuses on the fundamentals: smooth vibration control, reliable blade clamping, and a speed range that can be adjusted to match the material.
Throat Capacity and Workpiece Size
With 16 inches of throat depth, you can cut patterns that are up to roughly 32 inches wide if you rotate the workpiece carefully, though most users stay within 12 to 16 inches for comfortable control. That makes the saw ideal for portrait-style fretwork, decorative signs, wooden puzzles, and medium-sized intarsia pieces. You can also cut longer boards if the pattern allows you to reposition the wood as you follow the line.
For example, a 14-inch circular clock face, a 12-inch animal puzzle, or a set of ornate shelf brackets will fit comfortably on the Delta 16-inch scroll saw. If your projects regularly exceed 20 inches in width, however, you may eventually want a larger 20-inch or 22-inch saw. For most home workshops, the 16-inch size strikes a smart balance between capability and bench space.
Variable-Speed Motor and Control
The variable-speed motor is one of the most useful features on this saw. It typically runs from around 400 strokes per minute up to roughly 1,750 strokes per minute, depending on the model and age. Lower speeds give you better control when cutting hardwoods, plastics, or delicate patterns with tiny inside cuts. Higher speeds help you move through softwoods and thicker stock more efficiently.
In real use, you might set the dial near the lower end for a 1/8-inch hardwood ornament and increase it for a 3/4-inch pine toy. The key is to let the blade do the cutting rather than forcing the wood. If the blade starts to wander or burn, reduce the speed, check the blade tension, or switch to a sharper blade with the right tooth count.
Setup, Features, and Everyday Usability
Setting up a Delta 16-inch scroll saw is usually a straightforward process. You mount it to a sturdy bench or a dedicated scroll saw stand, install the blade, adjust tension, and check that the table is square to the blade. Because the saw is relatively compact, it can live on a workbench and be moved aside when not in use, provided you have a safe place to store it.
Everyday usability comes down to how quickly you can change blades, how clearly you can see the cut line, and how much vibration reaches your hands. Delta's design addresses these points with tool-free blade clamps, a dust blower, and a table that tilts for bevel cuts. Those features matter when you are cutting dozens of identical pieces or switching between materials.
Tool-Free Blade Changes and Tensioning
Tool-free blade changes are a major convenience. Instead of hunting for an Allen wrench every time a blade breaks, you can release the upper and lower clamps, insert the new blade, and set tension with a lever or knob. The Delta 16-inch saw generally accepts both pin-end and plain-end blades, which gives you flexibility when choosing replacements.
Imagine you are cutting a puzzle from 1/4-inch cherry. You start with a #3 reverse-tooth blade for clean top edges. When you switch to a thicker 3/4-inch walnut blank for a toy, you move up to a #7 skip-tooth blade. With tool-free clamps, that switch takes a minute or two instead of turning into a workshop chore. Proper tension is still critical: too loose and the blade wanders, too tight and it breaks or stresses the clamps.
Table Tilt, Dust Management, and Footprint
The cast iron table tilts to create bevel cuts, which is useful for decorative inlays, 3D ornaments, and angled joinery. Most 16-inch Delta models tilt from 0 to 45 degrees, allowing you to cut chamfers or produce pieces that fit together at an angle. A tilting table is not something you use on every project, but it expands the saw's range significantly when you need it.
Dust management on a scroll saw is different from a table saw or bandsaw. The blade creates fine dust that can obscure the cut line, so the built-in blower is important. You can also position a shop vacuum hose near the lower blade clamp to capture more particles. The saw's small footprint means it fits well in garages, basements, and apartments, but it should still be bolted down or placed on a non-slip mat for stability.
Blades, Materials, and Project Applications
The blade you choose often matters more than the saw itself. A scroll saw can cut wood, plywood, MDF, plastic, acrylic, and even thin non-ferrous metals if you use the right blade and speed. The Delta 16-inch scroll saw is designed around standard 5-inch scroll saw blades, which are widely available in pin-end and plain-end styles.
Understanding blade geometry helps you avoid frustration. Skip-tooth blades clear dust quickly and cut aggressively. Reverse-tooth blades reduce tear-out on the top surface. Spiral blades cut in any direction, which is helpful for beginners or for patterns with extremely tight turns. Crown-tooth blades are another option for fine detail work, though they cut more slowly.
Choosing the Right Scroll Saw Blade
For general scrolling in 1/4-inch to 1/2-inch hardwood, a #3 or #5 reverse-tooth blade is a solid starting point. If you are cutting 3/4-inch stock, step up to a #7 or #9 skip-tooth blade so the sawdust has room to escape. Spiral blades are excellent for inside cuts and patterns where you cannot easily rotate the workpiece, but they leave a rougher finish that may require sanding.
A simple blade chart can keep you organized. Use a #1 or #3 blade for veneer and thin plywood, a #5 for general fretwork, and a #7 for thicker toys or outdoor signs. Keep several packs on hand because dull blades cause burning, drift, and excessive hand pressure. When a blade starts requiring more feed force, replace it rather than fighting through the cut.
Projects and Materials That Shine on a 16-Inch Saw
This saw excels at detailed, decorative work. Wooden puzzles, fretwork panels, intarsia animals, ornaments, lettering, and inlay pieces are all natural fits. The 16-inch throat gives you enough room to handle most pattern sizes, while the variable speed lets you slow down for delicate cuts. It is also a good choice for cutting acrylic templates and thin plastic parts for shop jigs.
You can build jewelry boxes with intricate lid designs, custom coasters, decorative trivets, and children's toys. It is not the right tool for resawing thick lumber or cutting large cabinet panels, but that is not what a scroll saw is for. Think of the Delta 16-inch scroll saw as a precision detail machine that complements a bandsaw, table saw, and sander rather than replacing them.
Maintenance, Safety, and Buying Advice
Like any woodworking machine, a scroll saw benefits from regular care. Sawdust and pitch can build up on the table, making it harder to slide the workpiece smoothly. Blade clamps can wear out or lose their grip. The motor and linkages can accumulate dust if you do not clean them periodically. A few simple habits will keep the saw accurate and enjoyable to use.
Safety is mostly about awareness. Scroll saws are generally considered one of the safer power tools because the blade moves up and down with a short stroke, but they can still cut fingers and throw small pieces. Eye protection, good lighting, and a clean work area are essential. Never wear loose gloves or jewelry that could catch in the blade, and always unplug the saw before changing blades or making adjustments.
Routine Maintenance for Long-Term Accuracy
After each project, brush or vacuum dust from the table, blade clamps, and motor housing. Apply a paste wax or dry lubricant to the cast iron table so wood glides easily without staining the surface. Check blade tension and replace worn clamp screws or thumb knobs before they strip. If the saw develops excessive vibration, inspect the blade, the clamps, and the mounting bolts.
Every few months, depending on use, remove the lower blade guard and clean out packed sawdust. Check that the table tilt mechanism moves freely and locks securely. If you notice the blade drifting despite proper tension, the blade may be dull, the clamps may be misaligned, or the blade may be installed backward. A few minutes of maintenance can prevent hours of frustrating cuts.
Safety Practices and Buyer Checklist
Before buying a new or used Delta 16-inch scroll saw, test it if possible. Turn it on and listen for knocking, grinding, or uneven motor noise. Run the variable speed through its full range to confirm smooth changes. Check that the table tilts and locks, the blower works, and the blade clamps hold both pin-end and plain-end blades securely. Look for cracks in the cast iron table or missing hold-down parts.
If you are buying used, ask about the saw's history and whether it was stored in a damp environment. Rust on the table can be cleaned, but rust in the motor or linkages is a bigger concern. A fair price depends on condition, accessories, and whether a stand or foot switch is included. New models offer warranty support and fresh components, while used models can be a great value if you inspect them carefully.
If you have been looking for a scroll saw that can handle intricate projects without taking over your shop, the Delta 16 inch scroll saw is worth a serious look. Pair it with a few quality blades, a comfortable stool, and good lighting, and you will quickly discover why so many woodworkers keep a scroll saw within arm's reach. Start with a simple pattern, enjoy the quiet rhythm of the blade, and let your next project become the one that sharpens your skills.
