Hi Boston Blackie, I am very interested in your skate wheel mod from earlier in the thread; I know you said you used 1/4" x 2 1/2" bolts, (with nylock nuts), but what kind of skate wheels did you use? I can't get my head around the differences between Micro Scooter wheels or Inline Skate/Rollerblade wheels! Add to that they come in so many different sizes!!! Any advice would be welcome!
