Anyone add O-rings under their control knobs?

[BusDigger]

I don't recall reading this here, so maybe it's been discussed before? But I'd read mention of the control knobs being easily bumped out of adjustment, and by removing the knobs, and sliding a (1/4" ID) rubber O-ring over the control stems, and reinstalling the knobs will add a bit of friction, and prevent them from being accidentally moved.

Sounds like a good idea, anyone?

Yep done that with my Sliver Umax years back forgot what size 1/4 dose sound about right works great.

Done that here too, usually on all my detectors, also helps prevent dirt from getting in there.
Have to add one to my Eldorado as I seem to hit the Threshold...
It's always a great idea to add the o-rings

I have done it on a few Tesoro's, works great. Just a note - it takes a 1.5mm allen key wrench to remove the dials. Steve.

Scared me, Steve. Thought you had finally sold all your detectors and got an "L" rod and picked up dowsing!

I only have the Compadre. Forgot to mention that on some of the Tesoro's there are 2 set screws on the dials (Example ground balance dial on the Tejon). Got me thinking of something slingshot. Years ago I had this fella stop in that I knew was a well driller, I asked him about the dowsing rod thing, he smiled and took off to his truck, came back with 2 rods (looked like straightened out clothes hangers) he said here you go, put them in your hands and start walking. We had a garden hose laying across out yard for filling the swimming pool, and every time I got directly above the hose the rods crossed. I tried my best to hold them tight so they wouldn't move but I couldn't stop them. If I didn't have them in my hands I would of never believed it, one of the most amazing things I have ever seen. I have an uncle that has nothing to do with well drilling but has found spots for many people to drill for water, I guess he has a knack for dowsing.

I put the o-rings on my Tejon knobs.

What do you do to make sure things stay in registration? I haven't tried taking the knobs off, but is there only one way to reattach, so they don't go back on wrong?

The posts that the knobs go on are smooth and you can put the dial back on anywhere on the shafts, so what I do for example is turn the discrimination dial all the way to the left or all the way to the right before I take the knob off. That way after putting the o rings on you will know where everything goes if you happen to move the shaft by mistake. Hope I make sense. Steve.

Thanks for the confirmation on what I'd read (have a large O-ring kit handy, so shouldn't have to go far for those). Thanks too for the Q&A regarding orientation of the shaft/knob. I'd have automatically "assumed" there was a flat on the shaft.
