Prop damage from AWOL spinner

Last weekend I lost my spinner through my prop. I had removed it the previous weekend because the screw kept coming loose. I was going to leave it off until I found the right solution. An A&P where I keep my plane saw me messing with it, and came over to help. He went and grabbed a bolt and a difference nut plate, and put the spinner on. He didn't torque the bolt down as tight as I would have because he "didn't want to crush the nose of the spinner". I questioned him on it, asked if we should put lock-tite on it, and he said "naw, that ain't comin' off". Last time I take advice from him.

Two flight hours later the spinner went through the prop. Although the damage to the prop wasn't nearly as bad as I expected, I'm still wondering if my $1,300 prop is now a wall-piece. I've already contacted the manufacturer (Prince Aircraft) and I'm waiting on their response. Let me know what you think. I did fly ~2.5hrs after this occurred (after checking it out on the ground).

Tell me what you think...repairable or not?
