A reminder to musclebound, tool-happy and overzealous enthusiasts on the board: always heed to manufacturers warning of NOT overtightening.

Learned a $100 lesson tonight :(:(:mad:

Torque is a strange thing, it often takes alot less than you would think to secure two items together. Aluminum, plastic, and composites can't handle very much. We're all used to steel on steel where you can gronch the hell out of the nut and not worry.

You can get a cheapy torque wrench for less than your mistake, while a good one will cost you a few hundred. I imagine you won't be repeating this mistake anytime soon...
 
when that kind of stuff happes to me I do 1 or 2 of 2 things.
1. i say a poop, then i keep going.
2. i swear like a crazy mad trucker/sailer dropping every swearword i know (especially the F bomb) then i keep going


leason to you....just keep going.
but good luck nate
 
BTDT, the feeling you get in the pit of your stomach..... Kinda like someone just punched ya right in the gut..... And there's no one to blame but yourself... I shoulda grabbed the torque wrench :(

Then comes the look and the "I told ya so", followed by the "we can instal that for ya" from the guy behind the parts at the g-store when you go in for the same part the next day. Thankfully they leave out the "dumb sh*t" and "Jack azz" coments....

I feel your pain sir.....

Keep on truckin!

It's because a bolt or nut is an interesting mechanical device, with two key features.

The wrench is a lever, so the small force you apply out at a few inches is actually a very high force at the tiny thread diameter.
You might push on the wrench with only a few pounds but from 6" to 1/4" (radius of a 1/2" bolt) you've got a force multiplication of 24 times. Smaller bolts the force acting at the threads increases even more.

The second issue is that a bolt is basically a worm gear, which causes that force to multiply to compress the material being held.

Combined you could easily be applying a force a few hundred times stronger to the material than you apply to the wrench.
All on some small metal or plastic part.

Ok, now I have to go shoot something, I just need the snow to slow down enough to get to the range.
 
Bummer ....

I also learned not to work on firearms soon after installing steelies on a car for winter.

:p
 
Try shoveling snow for a couple of hours then peeling a christmas orange. HINT. Do this over the sink. Fine motor skills are not there yet. Kids got a kick out of it though.
