Going through the posts here, and following through to a few builder's sites, I've come across a lot of rotaries with adjustable give but not too many with adjustable stroke length. Dan Kubin's mini cranker I believe has an adjustable stroke length (or is it fixed on each machine with different stroke lengths available?) but most others just have different models with different strokes. Can anyone point me in the direction of more manufactures that have this option? And if there are others, are they readily adjustable (fine tune them during a tattoo; preferably making adjustments through a barrier bag) or do you pretty much have to strip them down to tweak the stroke?
Thanks for any input
