How do I determine what gears to use on a table mounted reciprocating device?
I am making a multi-function reciprocating device that will cut/crush many small materials from thin wood to aluminum/sheetmetal. Mounted on a portable table I have a small 120V motor for my power. I want to design my own drive system using available gears/sprockets, but I am not sure where to start or how to determine which gears to use to achieve my desired output SPM. I could use some advice and pointers on calculating gear size/teeth, which ones will mesh properly, and what type of gears would be best.
