Did you really ned to hammer the pistion down as 5:24? Mine did go in with just pushing it with my fingers ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iCMpI7Bl1Bc.html
Not really, the vice is just a bit high up for me to comfortably push it down, I was really just tapping it in. Those locking nuts are nice, I've seen them on something before but can't remember what.
