I must admit there's something special about watching a beam of light cut its way through a sheet of plywood, very satisfying!
The problem I've found is it's almost too versatile. I keep trying different things and then moving on to something else, wooden bowls, leather bracelets, wooden awards, the leather for the bike leathers as worn by Rebecca Ferguson (Actress) in Mission Impossible Rogue Nation, and whole bunch of other stuff!
I bought it as an addition to the business, but it's not as easy as they tell you to make money with it, good job it's not my main source of income!
Still, glad I have it and who knows one day it may even pay its way!
