|Hey again Rob,
On that particular setup I did use inline wheels. I'm constantly experimenting. That setup with the 4 nuts on each side gave me a truck width of 3 inches. For longboard wheels (with the recessed bearing seats) I use 2 nuts each side for a truck width of 2.5 inches. With standard rollerskate wheels (with the bearings flush with the back of the wheels) I use 1 nut each side for a 2.25 inch wide truck. I build all my skates from stuff I pick up for next to nothing in charity stores. Inline wheels work OK but they wear out in no time.
