- Old rusty fasteners make your project look terrible. We show you a couple of processes with heat, motor oil, and a wire brush to make your nasty bolts look better than new again. And don't even think about picking up that paint can. #restoration #howto #diy

Would love to see a rust test comparison on the different parts tested in each type of oil. Super cool!
We will put some of these outside and see how they do over the next few weeks.
@@Shoptoolreviews sweet deal, looking forward to it!
That was a neat demonstration. The effect from the brass brush was amazing.
That was a pre-anti-seize method back in the 1970s. A benefit of torching out rusted bolts,
Using metal containers would be safer as those thin water bottles melt when you breath on them.
Thank you. Correct, this process is actually pre-WWII era stuff. Yes, metal containers would be a much smarter choice, and now we know. Thanks for watching.
It’s VERY important to understand that this method will completely undo any heat treatment the bolt went through during manufacture. For certain grades of fastener this could reduce the tensile strength by almost half!! Do not do this to anything other than the most lightly loaded fixings you come across.
aand what do you suggest for medium/heavy loaded fixing?
Bead/vapour blast then cold blue
The brass brush approach is really interesting. But I'm curious how durable the finish actually is. Any chance you could wrench on one of those to see how well it does?
We are going to put some of these outside for a while in our Florida 90% humidity and daily thunderstorms. We'll also throw some wrenches on them and see how they do. Thanks for watching.
Your instincts are correct, that micrometer thin brass finish has zero durability, and is likely to rub right off when you're trying to install it.
Thanks for another great video brother. That brass affect is really slick. Do you know how durable that brass finish is? This is some really cool tips, thank you.
i've gotten a bluing effect on stainless using ATF in a similar process
✌️🐝➕
just curious, can you heat those crews using just a stove and not a blow torch?
I've gotten a similar color from using Evaporust on cleaned carbon steel? It will remove rust, but always leaves a blackened oxide type of color rather quickly, without heating the metal?
I save tin cans from the kitchen for things like that. At least they won't melt!
LET'S GO TJ..🏁
17:40... metal container ☝️
thanks! i also am a collector of gatorade/power ade containers for all sorts of unauthorized uses!... hah.. SFMF
I'm concerned that the heat will affect the strength of higher grade heat treated bolts. Don't do it to bolts that are for suspension for example. Still great for low stress parts. I'm going to try it for a few bolts on my '65 Corvair.
That's we're trying to say. Don't do this to critical fasteners. However, if you're just taking them to 500F it really shouldn't affect the integrity of the bolt. Thanks for watching.
Yes, he did specifically say towards the beginning that you should never do this for a structural bolt, but yes, 500F is definitely enough to anneal the metal, even some steels, so any of this should only be done for aesthetic or anti corrosive reasons.
ATF or Marvel Mystery oil would be interesting to try.
I use a method similar to this on gun parts.
Nice
What sprayer was that you used to degrease the bolts?
E: never mind I found it. Hazard fraught has a version for $35 I’ll probably pick up.
You can also use cold blue solution for firearms
That is correct, you can do that. That requires you purchase the solution, and we wanted to use things available in most shops.
apply with 110V..:A better way is brass bristle bench grinder wheel instead of a brush too apply the brass.
I did this to a bunch of bolts on my bike, love the brass effect, but they started rusting :(
Perfect way to destroy your bolts by heating
Everything about this is done incorrectly, or just plain wrong.
First of all, if you're looking for corrosion resistance, and your bolt is already zinc plated, DO NOT remove the zinc. Absolutely nothing you do at home is going to have the longevity as the zinc.
This brass finish looks great, but has zero durability, and will come off just as easily as it goes on.
The oil treatments will work reasonably well, and can look really good when done correctly, but this is NOT how you quench, which is the process you need to use to get it right. Please check out some blacksmithing videos for details, but you need s lot more oil vs mass of what you're quenching, and should always be done in a heavy, METAL container, never plastic of any type.
With all the metal you undoubtedly have lying around, why would you use a wood base?
You must have watched @caferacergarage 😂
