Dealing with rusty fasteners.

Check out this video. Simple stuff.

This works for pulleys stuck on shafts, stuck splines, etc as well.

Good to know.

Pretty neat. I wish I had known about that twenty years ago.

I will be trying that next time I go to Pick and Pull. Always snapping bolts there.

Great idea. Easy to carry along, eh?

Awesome. Thanks for sharing!

You have to wonder how this process was originally discovered. Maybe accidentally by some guy with a candle replacing a gear in a watermill before electricity................

 

Or something like that.  :yes:

Not sure where it started, but my uncle worked power plants and they used it. A buddy heard about it from an old man, used it to remove a stuck splined brake drum on a VW when nothing else was working. I told an aircraft mechanic about it, he used it to save a $700 helicopter alternator pulley.

holy crap.....that is amazing.

For those too lazy to click links:

 

This is interesting. I'm guessing the hot wax just gets pulled in and lubricates everything? I can't really see it dissolving rust or anything like that.

One other thing I find interesting is why he's using that silly four-way lug wrench.

Pretty much like solder gets drawn into a heated joint in plumbing.

Yeah, I wasn't debating the mechanism that draws the wax in (capillary action, yo) but the mechanism for unsticking.

Most penetrating oils bill themselves primarily as rust dissolving agents it seems, with lubrication as a secondary function, although most are too thin to be much good at it. The advantage of the candle wax is that when meted it's thin enough to get drawn in but thick enough when it cools to effectively lubricate, at least that's my guess. If that is what's going on, logically there would be a certain point of rustiness where this would stop working, as the two surfaces will have bonded to each other such that the wax won't be enough. Although I am tempted to go dribble some candle wax onto rusted metal to go see what sorts of rust-reducing properties it might have. I still think it's just a lube.

I'm interested on your thoughts on the wrench.  Are you suggesting an air impact wrench?  I think the four way gives you some feel for if it is giving.  A powerful impact wrench may help loosen the nut, but it may snap the stud off too.

Breaker bar and socket? I'm usually too lazy to drag out the compressor to use the impact.

My experience with those four-ways is that they're usually cheaply made and pretty good at making hexagons round. Like the cheapo spare tire jacks most cars come with, they're usually only good in a pinch, and probably not for very many uses.

I've only got a light impact wrench, maybe 450lb-ft. I can get that if not more onto a 2' breaker bar, and have broken all kinds of bolts without much effort. I don't know if I've ever broken one with the impact, though. The main advantage of the impact is it doesn't turn very stuck things very far with each percussive hit, which means generally it won't put enough stress into a fastener to make it yield, and the repeated percussion does tend to slowly break things loose. It's more likely you'll pull the threads out than it is you'll break it off, IMO.

But next time I've got something stuck enough to prompt me to pull out the rattle gun, I might just try dribbling some candle wax on it first.

I've snapped off more bolts with a breaker bar than I have with an impact. Like you said, the impact generates a different type of force, it's not continuous, it's percussive.

It just draws it in through heat, like I said I find that the crisco oil even works better

Ah, good point on a quality socket & breaker bar vs the 4 way.

 

Another way to prevent rounded lugs on our Jeeps is get rid of the crappy stainless capped oem lugs.  But that's a different topic.

Since today is the "Date which will live in infamy", this makes me think of my Grandmother, who was one of the toughest, most ingenious and adaptable people I knew ("hardy" would be another word). I bet she knew this and told me when I was a lot younger....and I forgot. It is great that this bit of knowledge is being recycled, I appreciate it. We depend too much on technology or special "formulations", when all we need to do is "MacGyver it".
