I have a Groz quick release vice that has jammed up in the closed position. This was proceeded, for quite some time, by the quick release bar slipping on me whenever I loosened the vice. I removed all the quick release parts and found that the threads inside the offset cam block (middle item in photo) were all junked up with grease and dirt so I cleaned it. I made the mistake of not taking a picture of the assembled parts and am now having trouble reassembling. It seems to go together properly only one way-and I've done that-but it didn't work at all. The handle just spun without engaging. Attached is a photo of the three parts I need to reassemble. Is anyone familier with this particular quick release? Any help would be appreciated.
