Sorry to hear about the machine again Dig!! You need some bits made out of diamonds, and a machine made out of unobtainium, then you'd be set!
Hope you get it fixed soon, I know it's probably a bummer for you to not be able to do your work because I'm sure you see it more as a passion than a job!
I'm usually on late night, sorry I missed ya on the Lil' Tart! I'd be happy to try it and give you some honest feedback if you're still looking for testers, if so shoot me a PM whenever you've got a free sec.
Hope you all have a great day, and Dig, hope you get your parts in soon so you can get back into the swing of things!
