So I have been using rotarys a month or so maybe a hair more, Ive got to use the soba one, the bishop and the stealth, and funny thing is I like the stealth the most not for every thing but I really like the stroke length. Its a bit longer then The bishop which I like. However I notice that lining with the bishop its very clean the ink doesnt go every where and its really easy to see your line work. I actually love the way stealth lines other then the small puddle of ink where im lining. I believe this could be solved with a linear motion. So I really want a linear machine with a massive stroke. Any ideas any one? I think a longer stroke allows the needle to hit the skin harder while still going slow enough to push the ink in well. I am not a builder but it seems to make sense to me.
