Awesome update!

There's an arm/guide attachment for the Roto-Zip Jigsaw base you have but I never bothered with it - seemed a bit junky.

Just find a nice piece of Aluminum angle to use as a guide. Home Despot sells the stuff in short lengths - 1/8" x 1" x 3' will do ya.

Nice, clean edges come as a result of the time you spend setting up for cuts. Take your time - be one with the RZoD...

Looking forward to MOAR.
