Should be done testing sometime this week
This is the chance to make this thing function the way it should. Pull back to zoom out. Pull forward to zoom in. That way you have more control over longer shots.
Wait, is the scopeswitch it the opposite? Can’t you just switch it around or..? I mean, not every single optic is clockwise in/counter-clockwise out (is it EU versions that are clockwise in?) I guess you could use one of those.. but I don’t see how/why it wouldn’t be reversible anyway but away should definitely zoom in and closer to you should zoom out.
Also, u/SwingGallowsSwing piano wire/guitar string/bicycle brake wire/any kind of steel cable (ideally multi strand/braided) has to be better than shoelace/paracord, or whatever is in the pic
Bike brake cable and good housing should remove the need for a roller and provide a better actuation. Running the housing between the end of the hand slide and the start of the actuator(s?) should make it feel really responsive.
