Hone stone adhesive

[ckucia]

Was going through a toolbox and came across some hones I have. One's for engine bores and the other is for drum brake cylinder bores. They're the spring loaded three-prong ones that run off a power drill and have long thin rectangular stones.

Anyway, the adhesive has let go on some of them and the stones fell off the metal mounts.

I searched here and on the web and am unable to find out what the proper adhesive is. I could epoxy them on, but that would be permanent. I'm assuming they need to be held on firmly, but not permanently so the stones can be swapped out when they wear or to use a different grit.

Is there such an adhesive, or should I just epoxy them on and get new hones when they wear out or I need a different grit? These aren't anything special - they were cheap auto part tools I got probably decades ago, although they have done the job when I need them.

Not something I need right away, but I thought I'd fix them so they're ready when I actually need them...

Hot glue from the corresponding HG gun?

I guess that would work. Turns out a HG gun is one tool I don't actually own, although they seem useful.

Doesn’t epoxy soften with heat? If you need to remove them later, could you use a propane torch to get the glue hot?

I don't really know, but that sounds like a possible plan. Heat is like a magic wrench.

Just buy new stones as they come with the backing plate already installed. Lisle would be your best bet of a manufacturer on those. But if your dead set on fixing them go to loctite or permatex site and look up the application. 3M ***** to dial it down.

New stones seems like the best way to go. Don't know why that didn't occur to me in the first place.

Maybe you were trying to figure out how to contribute to this thread

Funny you should mention that. Had an old chicken coop I built that I had partially disassembled and set aside. Wife doesn't need it anymore so I disassembled it completely to get it out of the way. I used construction screws and decided to save them since they're basically reusable.

Was thinking as I was sorting the screws into little bins how I used to make fun of the old timers for saving used nails and here I've turned into the modern equivalent.

Plus I saved all the wood that hadn't rotted because it seems like you need a second mortgage to buy lumber for a small project these days. In my younger days I would have just put it in the burn pile. Of course, that was when a 2x4 was a little over a buck and not closer to $5.

Funny how my income hasn't risen proportionally...

Epoxy doesn't soften that much with heat, usually would have to apply enough heat to make it brake down chemically which could work, unless the metal is heat treated then that is an issue. On the other hand, with different coefficients of expansion, a very brittle epoxy might release from heat cycling.

I've never had to do this but I'd be researching which types of construction adhesives can be removed using acetone. 1 part curing adhesives are far more likely to have a solvent than 2 part epoxies.

You will never get glue or epoxy to stick to the hones because they will be saturated with oil.

^ Stones are porous, I bet if it were washed in strong detergent solution first, the adhesive would stick to the stone as well as the metal... might even want to scuff up the metal to improve adhesion, or maybe not, not knowing how good it'll be yet, maybe want to be able to get it back off again per the topic goal.

$12 for new stones … why are even talking about different types of adhesive.

^ If you have various adhesives and the stones lying around anyway...

Then there are some people who always have a SHTF mindset, what would I ever do if suddenly there were a pandemic or something and supplies were scarce, especially those who grew up before there was amazon and a walmart every 2 miles in any direction, who live in a remote area.

I'd totally try putting them back on rather than just wasting them, even if it is only $12. Worst case, you buy some adhesive, it doesn't work well, but you still have the majority of the adhesive left to use for something else. I always think in those terms when buying adhesive anyway, there's usually only a little needed for a one-off project yet buying a tiny amount costs a lot more (per quantity) than buying the larger size. The trick is then, estimating adhesive storage life. Some adhesives can go years once opened, while others, only a few months if that.

It is useful to gain experience using adhesives. You can always buy a new widget if it doesn't work out well, not like that bridge is burned or anything. Either way I always have epoxy on hand. It's saved me thousands of dollars over buying new *things* that epoxy was able to repair.

I kinda feel like the spirit of this forum is towards DIY rather than just buy new stuff... just sayin'.... Plus sometimes the new stuff you buy, is junk compared to the old!

I would buy the new stones then try to glue the current one just to see. That is one of those tools that I would hate to need it now and have one of the stones come loose. My wheel cylinder hone showed up while cleaning the garage a couple of weeks ago. I've had pretty good luck with fixing things like that. I disassembled an old clicker torque wrench and figured out how to repair and calibrate it after I had already bought the new one. One of my flat screens I disassembled and repaired while watching a YouTube video on how to do it on the new one.

Plan is to get new stones.

But I am in a very rural area and do tend to get into a "know how to fix it in case I can't buy it" mindset because stuff happens and the nearest city is 45+ minutes away. Also, here in the rural South, plenty of places are closed all day Sunday and most of the day Saturday - when I would need them the most.

Was different when Amazon Prime had two day delivery. Nowadays we're lucky if we get stuff in a week and sometimes it's two. If I can't get something locally (which is probably 75% of the things I purchase), I'm basically dead in the water on a project until I can get it online. If the supply chain gets any more screwed up, I'm going to be fixing a lot more because buying won't be an option.

But I'm not in a hurry on the hones, so in this case buying makes more sense.
