Hi all, im sorry for the silence, and im happy i have sent the machines already and you now have positive and negative feedbacks in which i really need that for future development. about the splatter, please try not to push the needle grommet lean on the end of the needle pin. We will extend that 1mm more so that when you push back the grommet, the needle bar will stay on the middle and will prevent from any splatter. also we still have to develop more on the machine connection, change it into RCA. and the vise lock needs to be changed design for a better grip on fingers, it will be a simple wingnut design so that the fingers will have a better grip on the lock and no more twisting of the tubes. on our next run, we will file the sharp object that is intended to be a hook for the rubberband. and we have just found a way on how to have it with a complete give. we are now testing our experiment and it works like a dream... please send me more input for the future change as we will have our next batch of run very soon. i appreciate all your support and feedbacks, it will help our product arrive to the best it can. thank you.
