those of you who know me may know that im never content with using stuff off the shelf as it were. im compelled to modify or make my own. this is my attempt at a mechanical srt device. as of now ive only made them by hand in my woodshop. still a lot of testing to do and some details to sort out. as soon as i have quantities on hand im hoping i can recruit some guinea pigs to try it out . what do you think?Click image for larger version.
