I used this machine on a large sleave piece the day I built it. I did the intire outline and did the first session of black and gray with ease. I did the 2nd session Wed. afternoon 5 days later and the black and gray had already pealed. I'd say you can do any type of tattooing with this machine. Springs can be changed and the tension adjustment is long so needle tension will give you all the adjustment to do what you need. Cost is $300 for aluminum and I am working on a production steel frame as well, for later release.
