The Delta 40-694 20″ is one of the few competitors to Dewalt’s extremely popular DW788 model.
Like the Dewalt, the Delta has a 20″ capacity, dual parallel link arm design, and premium construction.
Delta says that the unique dual parallel link arm design reduces vibration and noise and keeps the blade perpendicular to the work surface which dramatically reduces over or under cutting, improving accuracy and quality.
The table is made from cast iron. Its size can support larger workpieces, and its heft should help to keep things stable.
Additional features include a variable speed control, flexible dust blower, blade tensioning lever, tool-free blade clamp, and on-board storage area.

The Delta saw sells for $598 at most retailers, and at the time of this posting it appears to be on sale for $472. I have not used this model before, but it looks to have very good ratings at Amazon and other retailers.
According to Amazon, the MLCS Billy pedal foot switch is a popular add-on accessory. The deadman-style switch allows users to control the scroll saw with their foot.
Compared to the Dewalt DW788 Scroll Saw
Dewalt’s specs are very similar, matching the Delta’s motor power, speed (strokes per minute), and stroke length. Both saws’ tables can also tilt left and right to 45°. The Delta beats the Dewalt’s cutting capacity at 90° by 1/8″.
What’s interesting is that the Dewalt has a tool weight of 56 pounds. It’s also made from cast iron, and it’s unsure where the Delta gains an extra 14 pounds.
Extra weight in a saw like this is a good thing, as weight can provide extra stability and help reduce vibrations.
