The steampunk vintages Singer sewing machine mystery project

Take a couple of broken sewing machines, some stuff found in the back of the workshop and a bit of creativity, and you get something that looks suspiciously like a science fiction ray gun.

I assure you, it's really not.  It's completely designed for function, the fact that it looks awesome is just a side effect.

Think cutting rather than shooting.  This is for the nether regions of my currant mystery project where I transform a damaged vintage Singer sewing machine into something a little bit different, yet highly functional.
