Anyone Here Tired of Loose Pivot Screws?

Well, I have to say that every once in a while I'll have to tighten the pivot screw on my emerson...I dont see it as too big a hassle, actualy, it isnt one at all.
 
I don't see occasional adjustment as a problem either, but when it becomes a daily necessity, there's a problem. I've been downright abusive to my BM 710, flicking it open so hard that the lock sticks sometimes, and the pivot is still at the perfect tension after at least three months of use. Some of that may be due to the Axis lock, since it doesn't put any lateral tension on the blade the way a frame lock will, but whatever the reason is, I'm impressed.
 
Well, I asked for opinions, and I have been answered. It seems like no one is really interested, and are happy with current methods. That's cool by me.
So, I won't bother with any further grandstanding. Maybe one of these days if I decide to make myself a hard use folder, I'll quietly use the design myself. Or, if someone else comes up with the same idea, I'll be sure to report back crying that I thought of it first. :D
 
I must be doing something wrong -- I've never needed to tighten a pivot screw. Seriously, though, check with some of the folder makers over in the Shop Talk forum; maybe one of them would be interested in some sort of collaboration.

It ain't no "immutable law of physics". :D
That's what I'm trying to say. Not with lock washers, but with a design that is just as or more dependable [as the lock washers], as easy to make as current pivot systems, and does not disrupt the aesthetics either. If that were available, would you prefer it over lock-tite? Granted, I suppose you could still slather on lock-tite to your heart's desire, but hopefully it would not be mandatory.

It's like you're asking me to change my religion or something. :D I've been using it for so long I don't know what I'd do without it. I suppose I could give it up if there was a good alternative. Is there a 12-step program to help me stop?
 
Well, something just happened that has caused me to reconsider developing my idea further.

I was just at a company meeting, where we were discussing equipment used to apply agricultural chemicals. As with most such meetings, we spent a good portion discussing spray nozzle tips, which spray chemicals onto the crops. There are hundreds of different nozzle designs for use in different applications, because of differences in speed, spacing, rate used, etc. Selecting the wrong nozzle can (and does many times every year) cause a poor job, or a drift complaint, both of which easily become multi thousand dollar problems. Field conditions vary so widely, that it is pretty much impossible to use one nozzle that will do a good job for everything.

A year and a half ago, after sitting through another such meeting where we spent a whole afternoon on this subject, I wondered why someone didn't just make a nozzle that would self adjust to the pressure and rate. ??? So within an hour of thought, I worked up a simple design that used a spring loaded piston to adjust to pressure variances. I drew it up on the back of a notepad, and shared this idea that night with a coworker at our hotel. He said, "Well, ya aught to patent it before someone else does", or something like that.

I just found out someone else has developed such a nozzle based on my same idea. The man speaking basically said they are still refining the design, but it will make all these hundreds of current spray nozzle designs obsolete, and will become the industry standard within the next several years.

I also have a simple idea for improving certain modern muzzle loading rifles. One of these days, I bet I'll see someone else's name on it as well.

I think even if my pivot screw idea never takes off, I'd at least like to say I did it first. But, as with most ideas, they're 10% inspiration, and 90% perspiration. I better get to work.
