Mr.sig239
, I started writing the before I sat down to an early supper and am now picking it back up after you posted your vid.
I think it's time for you to open up that RDD of yours for a good interior cleaning and polishing. Mine wasn't in any way bad when I got it as our friend
CPP
had the knife apart a couple times before passing it along, but I find so many bearing flippers to be full of glompy grease past its prime doing nothing but impeding the action. If you're interested, I've got a post over in the
Disassembly Pics thread with interior pics of my RDD. There's no "how to" with it, so a few thoughts on my experience and methods....
I always start by cleaning everything thoroughly with isopropyl alcohol--in a bath, by wiping down, or both.
I polish all moving interior contact surfaces. I've got an old green-loaded leather strop I use for this. Pay special attention to the underlay washers and the roller bearing cages.
CPP told me to be careful re-installing the roller bearings as they have a tendency to stand on end when inserted. Also, grabbing them with tweezers can result in flying bearings almost impossible to find. I have a fine-tipped, magnetic tweezer that I use without pinching to pick up BBs and roller bearings, pushing them off into their receivers with a toothpick or similar object.
I dislike grease and lube all my knives, save those with Teflon washers, with W10 NanoOil as I find the lighter lube lets the moving parts move much more freely.
I can
make my RDD not flip out if I try, but it always comes out easily, surely, and with no wrist when light-switching under normal use. I expect yours should too with a bit of TLC.
