Anytime you wanna start building mods, lemme know and I'll point you in the right direction! I'll help all I can plus I can turn you on to a couple groups on Facebook that are excellent for info!
As for the engraver...It's at my shop as there isn't room for it in my house, so I still haven't had the time to master it. When I move, hopefully I'm April, it's getting moves to the new house and I'll be able to put some time in it and get it figured out.
Are you any good with the laser?
