What Makes A Quality Saw? Nowadays, you can pay anywhere from $650 to over $1,90(1 tor a precision scroll saw. How much___ you spend depends on the features you warn and how much capacity and mechanical precision you need. Naturally. the more you pay for a scroll saw. the better you can expect it to perform: at the very leasi, the machine should make smooth, precise euls that require little or no sanding. The blade should follow a line without excessive drifling to one side or another, and should not bow in the eul when scrolling thick stock. And a precision scroll saw should operate smoothly with minimal noise and vibration. Cutting capacity is a second consideration: the throat depth of the saw imeasured from the blade to the back arm of__ tin- saw i determines the largest workpicce you can cut on it.

Each machine operates a bii differently in this respect. I'll discuss ihese and other features in more detail later. Which Saws Do the Experts Use? In the world of precision scroll saws, four names immediatelv come to the minds of veteran scroll-sawyers: Delta. Excaliber. Hegner. and RBI. These lour manufacturers have the reputation of making quality "high-end" saws, w ith price tags to match. For this review. I asked each company to send me their best-selling model. These turned out to be 18 in. to 20 in. saws (RBI also sent me their 16 in. saw): the makers agree that this size range is the most practical for doing most scrolling projects.
