This is the tool I have loaned out. I've used it only once and I don't think it does the job very well as its intended.
To help me get my bezels tight I put an "O" ring between the door and the ferrule and also one inside on the end of the ferrule before trying to get it tight..... I wasted a couple ferrules but was never truly satisfied. Just never got it TIGHT.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
