The Eclipse Scroll Saw frame utilizes a heavy-walled aluminum sand casting frame for its rigidity. The 1.5” blade stroke is great for intarsia. This longer stroke spreads the heat and wear over more of the blade making it last much longer and clears sawdust better. This saves you both time and money.Since it has a true vertical blade action (ideal for marquerty and intarsia) and a positive pull from the top to bring the blade to the top of the stroke. Blade breakage is all but eliminated thus you won’t mind using a tool for the lower blade clamp.
