Flex Shaft Chop Saw
prusaprinters
Tons of accessories are available for Dremel tools but none for flex shaft tools. So here's the second in a series I'm developing. This chop saw can swing a 2 in, diameter blade or cutoff wheel and it can accomplish reasonably consistent cuts. I've added a miter gauge with 5 degree divisions but I wouldn't depend on it too much. :-) Note: I've yet to devise a decent blade guard so BE CAREFUL and wear eye protection at the very least. 2021_02_11: Uploaded pieces so those who wish can hook up a retract spring to keep the saw from falling freely onto the work. New base holes can be threaded M3 and spring hooks can be attached with 3: M3 x10mm SHCS. Use one or both as you see fit. Slip a rubber band around the tool and the other end can hook at the top. The new base designs are slightly wider on one side to make room for hook fasteners. 2021_02_15: Printer problems all fixed and I've now finished printing the thing. Along the way I redesigned the Spring_Hooks and the Blade Guard.

Pivot needs support 'touching buildplate' Arms can be printed without support. Flex tool can be fastened to arms with M4 x 8mm screws Arm brace can be fastened with M4 x 8mm screws Arms are fastened to pivot with one loooong M6 bolt. Note the right hand hole is small enough to be tapped. Pivot can be bolted to base with M4 x 10mm screws and nuts Base B is a mirror image base and is attached with M4 screws, using spacers to provide blade clearance through the gap. Fences can be printed or made from angle aluminum. The distance between bolt holes is 50mm. Blade Guard halves can be assembled with M3 x 8mm SHCS Spring Hooks attach to Base with M3 x 10mm SHCS Category: Hobby
