hello all, I purchased a router a few years ago, but other than familiarizing myself with how it works, it's been in the garage all this time. now that I have a little extra time I have some home projects that I believe the router will be very applicable for. it's a basic ryobi router, nothing fancy. while I was turning the depth ring, I found that there was some resistance to it. I'm thinking of spraying some silicone on the threads so that it turns easier. the locking mechanism for the ring is also hard to turn to lock. should I do this? or is there any safety issues? thanks
