Well I got out my depth stop chuck today to work on an out feed table I am building. It worked fine when I put it away and all the other chucks (Centrotec, offset, right angle, etc.) work today.  However, when I install the depth stop chuck it does not spin.  I am baffled because this is the chuck I use the least.  No chance it’s wore out and I know it has not be dropped. 
Any suggestions FOG? Thanks
