Switched out AO wheels for the CBN today but have a question. The Delta uses a winged arbor nut that you spread open for locking in place after you tighten the nut on the shaft by hand. See pics. They seem to work fine with the new wheels and don't see how they could loosen up but wanted to see if anyone else had switched out this style for a regular nut or if leaving these winged nuts on was completely safe or not. I think they are completely safe this way but I don't know how much I like the idea of those wings spinning around without some type of guard around them. Any opinions?
