Made a thing;

[Chukster]

Made a thing the other day; I took a standard 7/16" open-end wrench, and hit it with the grinding wheel, and made the business end thin; like a tappet wrench.

It's for certain type of coaxial cable connectors, and they're made with flats for tightening, but need tappet wrench thickness.

Works fine, but the newly ground surface is kinda rough and I'm worried about it rusting. Anything I can to to it to prevent that?

You could hit it with a coat of primer and then some rustoleum, though it will probably wear off pretty quickly under use.

Smooth it out with a flap wheel/other means then bring it to a light polish and seal with a wax or oil coating.

I use boiled linseed oil on a lot of unfinished steel/iron projects.
May need to reapply from time to time, depending on the environment it is used/stored in.

I've had luck sanding and buffing out rough surfaces with a polishing compound. I rub on some clean oil to help keep away rust if I don't feel like polishing to a shine.

I did the same thing with a 22mm wrench for my snowmobile suspension.

it rusts. I hit it with WD40 Specialist rust inhibitor that supposedly lasts 12 months. Really depends how much you handle it.

It works if the wrench is sitting but if you touch that part of it alot it will wear off. i just hit it quick every time i use it and its good until i need it again.

I use that stuff on my south bend 9" lathe that is in a un heated un insultead garage in new england and it keeps the rust off of it.

As mentioned, smooth and polish then use cold blue. I like Oxpho blue as it is a phosphatizing agent. Then keep it wiped with an oily rag just like your other tools and guns.

You must have extra large cable connections, most of mine are closer to 7/16 than 7/8".

YerRIGHT!! corrected. thanks.

I just paint mine when I do something like that.

YerRIGHT!! corrected. thanks.

If you need a 7/16" little guy, I'd suggest getting one of those old craftsman ignition wrench sets. They go up to 7/16" in SAE and they're tiny, very flat.

I use gun blue to prevent rust and looks decent too

Paint it pink. It will help ensure you can find it when you need it, plus serve as a theft deterrent.

You are correct - grinding stone will leave that rough burred surface which is very susceptible to corrosion. The closer you get that surface to a mirror finish, the better resistance to corrosion it will have, that is, the slower it will rust. If you want to take it to 11, sand it down with increasing grits and finish with a buffing wheel with green and/or white compound until you can see yourself in it. Then hit it with a clear coat or wax or oil or blue phosphate as suggested.
