I have a cheap reciprocating saw that is 120VAC, 60Hz, 4.5A. Says 0-2300 strokes per minute and has a dial speed adjust,k but slowest is still around 300SPM, I need to slow that down more for a custom project I am working on for a hobby idea. How does the speed control built in work? Any way to duplicate that inline with the AC plug? Is there a way to add an inline circuit to slow it down? If you have any ideas, please share and possibly add schematics. I do not want to have to replace the motor or open the case in any way, so an in-line device would work perfectly.
the alteration you suggest could be dangerous or damage the saw motor. If you want to take a chance try plugging the cord into a variable speed outlet like a dimmer switch ... best to take it to a competent repair person...under 300 strokes per minutes is getting down to the hand saw level... be sure you have a gfi plug to reduce the chance of damage.
Try plugging it into the footpedal of a sewing machine they are the best speed controller in the world. you can probably find one at a thrift store or a garage sale for cheap
a hand saw would probably be the cheapest option
