Been a very busy 2 weeks hence the lack of posting, but like always I've actually been making a whole tonne of stuff. I'll start with these laser engraved beer glasses. There is a micro brewery in the unit next to ours at Just Add Sharks. I engraved one on the laser using the rotary attachment and they decided that they would like a hundred. At 5 minutes for each glass this gave me a whole 10 hours of fun changing the glasses over all the time. I would say 100 is just about the limit for mass production engraved items, any more and there is probably a cheaper/more efficient way of doing it.
