Continuing the discussion from Epson large format training in July?:
@MrsMoose & All:
There is one opening left for this weekend’s Metaza class.
Here’s the link: https://calendar.dallasmakerspace.org/events/view/3358
I can schedule one or two more the following weekend (August 26th and/or August 27th) if there is enough interest.
Thanks!
Lisa
Welcome back lisa! 
I am very interested in one next week I have to be elsewhare on Sat
Thanks Devin! 
Cairenn and all…
I have scheduled another Metaza class. It will be held on Saturday, August 26th at 10:00 PM ~ immediately following John’s Vinyl Cutter & Button Maker class. It should show up on the calendar in about 36 hours.
Already full. Do it again hahaha
Amanda,
The next class will be on the 26th. I’m guessing it will show up on the calendar this evening. It’s scheduled to immediately follow John’s class that evening.
Got in that one! I’ve got some pure copper blanks I want to try in it. Will those work?
Awesome! See you then!
Yes, as long as they aren’t too thin. It must be at least 0.3 mm thick. They will engrave best if they are also flat.
Sweet. I’ll look up what the gauge equivalent to that is
Because apparently I have time on my hands…
.3mm=.0118 inches, or ~.012. (@ 25.4mm/inch)
This would be called “12mil”, but is apparently not readily available/sold for copper sheet.
Instead, the nearest choices generally available are 10mil @ .010", aka 8oz.aka 30 gauge or 16mil @ .016" aka 26 gauge aka 12oz.

curious what you have. Sure you have MUUUCH more experience than I with copper, so just curious…
The bit I was planning to use is 18ga
18ga = 0.0485”, so it should be fine.
