Slotted table inserts are great for blade threading.

They allow the blade to tip far enough forward so blade threading can be accomplished without removing the blade from the lower holder.You can also make zero-clearance throat plates for delicate work, such as marquetry.

Vibration is minimal on the DeWalt. due in part to the short pivot arms that hold the blade.

a pre-drilled hole in the pattern. DeWalt's moveable tipper arm (Photo 4) and the slotted table inserts on the Craftsman, Harbor Freight and all the Delta machines simplify blade threading (Photo 5). That's because the blade only needs to be released from the top holder. On other machines, the blade has to be completely removed before it can be threaded back through the workpiece.

Low Vibration

Scrollsaws are often used for hours ai a stretch, so low vibration is a godsend. The DeWalt saw was noticeably smoother than the others we tested. No doubt the heavy cast iron table helps absorb vibration but perhaps the reason for its smooth operation is the arm design. DeWalt has moved the pivot points of the moveable arms forward, thus shortening the arms and greatly reducing vibration (Photo fi).

Another smooth-running saw is Delta's 40-650. Delia uses lightweight Kevlar arms and a heavy cast iron lable to reduce vibration on the saw.

Most scrollsaws have pivot points toward the back of the saw (Photo 7). The long arms moving up and down at 1,700 strokes per minute make these saws more prone to vibration.

Easy-to-Reach Controls

The Deity 40-650 and the DeWalt are the only saws with all their controls, including power and speed adjustment, up front and on top where they can be easily seen and reached (Photo 8). While this is a great convenience for most users, it's almost a necessity for others. One of the great things about a scrollsaw is that it can be used in ihe seated position. This allows people confined to wheelchairs, or those who don't wanl to stand for long

Vibration is minimal on the DeWalt. due in part to the short pivot arms that hold the blade.

Vibration is more pronounced on all the other saws because of their long pivot arms.

AM the controls are on top and up front on the DeWalt. That means all operations can be performed without having to reach into awkward or blind areas under the table or at the back of the upper arm.
