GUVNOR MK3. 
Although sharing the same namesake as its predecessor the Guvnor MK3 is a totally different beast. 
With a completely new geometry it’s feel sets it totally apart from earlier models. It now has a 5.5mm cam rotation. But due to the extremely coil like hit at the bottom of the cam which takes 0.5mm of impact the functioning stroke of the Guvnor MK3 is 5mm. But there’s more than just this that gives it so much more power. By hitting out 0.5mm from the bottom of the cam we are penetrating the skin at the fastest part of the cam rotation. This is why it vastly surpasses the power of any standard rotary machine than boasts a 5.5mm stroke. After numerous trials and discussions with very experienced tattooer friends and colleagues my aim was to make a machine that was out of the box capable of everything you want from Cartridges and standard needles alike. The objective was to give a maximum stroke of 5mm so that it would not break cartridge membranes but with a much much harder hit than you have ever experienced from a 5mm usable stroke machine. The Guvnor MK3 acieves this due to its Flexi Cam system. The other big advantage here is the weight distribution. It is  approx 40 grams lighter than the Guvnor MK2 weighing in at 160 grams. But what makes the weight distribution even better is that it is also 40% more weight forward than the earlier models making it sit over the hand very comfortably and with far less vibration than you’d expect from such a powerful machine. I have tried my very best to get the best of both worlds here for Cartridges and Standard needles and I’m really happy with the end result. For standard needle users included in with your machine is a 90 degree brass elbow for the RCA cable to come conveniently out of the back of the machine and completely clear of your hand when tattooing. 
I think that covers most of what I can say here for now but if there’s any further information required please shoot me a message and I will do my best to answer your questions.
