Inductive Heating Tool for Removing Rusted Nuts

[Jonny H]

Stop whinging. You guys in the US don't know how lucky you are with the price of auto parts, tools and cars.

In the UK, similar heaters retail at around £600, that's over $800!!!

Who knows, maybe I'll build my own. Maybe someone else will see a business opportunity and offer them for a more reasonable price. Probably wouldn't be made here though.

All that managed without mocking sarcasm. Straight up.

Not exactly. In my world, if you don't do you ought not disparage those who do do, especially without knowledge of what it takes to develop, test, get regulatory approval, and bring a product to market with its attendant financial risk. We depend on those that do for the things we need as well as the things we enjoy.

I do mention several people who have built their own tools, products, etc and single them out for my undying admiration.

And again, mocking sarcasm isn't a good thing. I'm sorry.

That's some excellent logic. [mocking sarcasm]. That knocks out probably 99% of the pelican community from ever commenting on price/value/quality of any product or service. Did you like the book? Can't comment, I've never written a novel. How about that steak? Hmmm, I never been to a slaughterhouse or run a restaurant.

But I see--by your standard--being a consumer is never enough. Unless you've "walked the walk" you're just "spouting off." Interesting perspective.

Yesterday, I was thinking about all the tools I've purchased and used just once. For most of them, the expense was justified. Guess this may get added to that list.

Rutager,

You probably will not use this tool for a while. Something came to my head during my sleep and dreamed about my struggle to remove the 6 fasteners for my ‘89 power seat. I believe these fasteners had thread lock applied in the factory. And there are two seats in the car with total 12bolts. Would you consider making this tool available to the comminuity?

For example, I will make a $400 deposit and borrow this tool for several days or a week. And return the tool in same condition as received. Then a deduct a user’s fee say $50 from my deposit. This electrical tool is somewhat delicate and sensitive and should be handled with extreme care. If I break it, you got my deposit to cover for the repair or what. What do you think?

Keep us posted. Thanks.

Hi Tony,

I wouldn’t have a problem loaning out this tool to trusted members of this forum- don’t really want to get into the business end of tool loaning though. Kind of a case by case basis I suppose.

Best,
Rutager

Its a freaking electric charcoal heater from 1982!! I see no advantage over a torch or a $10 bottle of mapp gas.

Er, not exactly. Those charcoal heaters are resistance devices (like a light bulb filament), where they heat up due to resistance in the metal. In induction devices, like this gizmo, the AC operates at a certain frequency, and the "object" it is targeting (what the coil is wrapped around) is what heats up, not the coil device itself. It is very efficient and clearly safer than an open flame. Whether it is worth $400 is up to the user, the application, and the value of time, effort, and safety...

[Dpmulvan]

Lyle I'm just busting balls, yes I know the difference between induction and resistance heating. You can build one of those $400 units for $20 either from scratch or you can buy a circuit board off eBay. I just think it's wrong to rip people off for something that can be built for a few dollars. I guess that was my point.

[NYNick]

Gee guys, I thought it was cool. One broken stud in the wrong place and you'd be wishing you spent the 400 bucks.

Let's talk politics next!

I wanna see this nut busting $20 home made contraption !

Get to work.

[Quickstep192]

Maybe dumb question.... Do you remove the bolt while it's still red hot? I was wondering if it might have a tendency to round off because it's soft?

Have you removed the studs?
If you can get the studs out without breaking using that tool I'll be sold on it's abilities.

I’m not that crazy! I’m going let the machine shop that rebuilds the heads replace them.

I’m not an expert, but I think heating the studs would make them get tighter in the heads, where with the nuts, the heat expands them away from the stud- or maybe just breaks the rust bond?

Yup, remove the tool and put the socket on right away. Mine turned right off with very little effort. In fact they got so loose after a couple turns that you had to remind yourself not to turn them off by your fingers unless you wanted third degree burns.

[BlueWing]

Is there any benefit to spraying cold water on it to cool it quickly and shock the corrosion.

I have done that in the past and when multiple bolts/nuts are involved or time is not an issue I than give it a shot of Kroil.

Works great, shocking.

I am about to remove my original exhaust on my '79 and replace with ssi. Rost ice max is my normal go to for rusty fastners. This thread made me curious. Thanks tonthe wifes amazon prime account i got this thinf for $11.29 and free two day shipping. Came today so thought id try it out. Red hot bolts in less than a minute. I probably need some longer cmaller coils to fit in the gaps but combined with the rost ice i am ready to tackle this . I have a oxy torch on the bench just in case.

Here's a set of different size "Bolt removing coils" for less than $20 to go along with your unit. Nice find and pictures, thanks!
Sure beats a $400 unit!
Question:what did you use for a power supply? Battery or DC power supply?

EDIT: here is a 23" form your own coil from Mini Ductor, would probably be real good for heat exchanger nuts.
