This 535mm(21") scroll saw is the mid sized model from a range with some really different features not found on any other machine. Constructed mainly from plate steel including a 7mm heavy gauge steel table with an epoxy painted surface. Two unique features make this machine stand out from any other. Firstly, the blade actuating arms are very short, driven by a lever and rod mechanism. This gives very high control of the blade plus exceptionally low vibration. Secondly, the whole arm assembly tilts 45 degrees from the vertical left to right, leaving the table horizontal. This allows much better control of the work, due to greater visibility and being able to work at a natural position. You are not fighting gravity or bending your wrists into awkward positions. This machine is not short of other features, having a variable speed control system giving from 400-1,500 strokes per minute. Blade changing is easy and tool free, with two hand clamps and a quick release lever. An air blower and work hold down are provided. Plus there is efficient dust collection when connected to a suitable fine dust extractor. You are recommended to permanently mount the machine onto your workbench, or to one of the dedicated stands available as an option. Using unpinned blades means there is a large selection of blades available, or you can use 150mm lengths of 1/4" bandsaw blade, ideal for cutting thicker materials. This is a serious machine for craft or joinery work, not the same as any other.
