+Jolly Roger Posted April 15, 2008 Share Posted April 15, 2008 Ok, so I started making some caches for putting around the area and I am having the hardest time finding some glue that will work. I purchased some high power magnets and plan on making a few magnetic caches. In the order I also got some lower power ones I put on a pill box for a cool little magnetic cache I put out. First I will start with the high power ones. I have gone from super glue to 2800psi epoxy and I cannot get them to stay on the lock and lock I have tried to attach them to. I have sanded the area I wanted to attach to make it a little more rough so the glue will stick better, but to no avail... Then I had the pill box all set...the super glue seemed to be holding these smaller magnets just fine but after checking my cache last night I had to replace it since 3 of the 5 magnets pulled off. Anyone have any suggestions? Thanks! JR Quote Link to comment

I would try to glue them on using a flexible adhesive like Marine Goop. Quote Link to comment
+Totem Clan Posted April 15, 2008 Share Posted April 15, 2008 +1 to sbell's post. Another option I've seen is gluing strong magnets inside the container. That way they push down on the glue/adhesive, instead of pulling away from it each the cache is removed. Quote Link to comment
CacheNCarryMA Posted April 15, 2008 Share Posted April 15, 2008 Use one magnet on the outside with GOOP and one magnet on the inside with GOOP. Stick the magnets together. Quote Link to comment
+Zolgar Posted April 15, 2008 Share Posted April 15, 2008 If you're not in a hot environ, hot glue will work too (sticks to anything). As said though, put the magnets inside the container. If you're someplace where it's gonna get hot inside the cache though.. Hot glue = baaad. Quote Link to comment

It pops right off. Quote Link to comment
+Fishnic Posted April 15, 2008 Share Posted April 15, 2008 silicone caulk is the best glue i have ever used for attaching 2 different substrates together. Quote Link to comment
+Thrak Posted April 15, 2008 Share Posted April 15, 2008 I'd have to agree that using strong magnets placed inside the container is probably going to work best for you. I like the magnets from old hard drives. They are insanely strong. Quote Link to comment
+briansnat Posted April 16, 2008 Share Posted April 16, 2008 I'd have to agree that using strong magnets placed inside the container is probably going to work best for you. I like the magnets from old hard drives. They are insanely strong. That's what I do, put powerful magnets inside the cache. That way all I need is some duct tape to hold them in place. Rare Earth magnets work great for this. I have a hard drive magnet inside an Altoids tin and that cache gets frequent complaints that it's too hard to remove. I've also used two of these 1" round Rare Earth magnets in the lid of Lock n Locks and they have held the cache solidly in place. Quote Link to comment
vtmtnman Posted April 16, 2008 Share Posted April 16, 2008 silicone caulk is the best glue i have ever used for attaching 2 different substrates together. The stuff is MADE to be in the weather.Best outdoor adhesive you can get.Use the cheap clear stuff. Quote Link to comment

+Lacomo Posted April 16, 2008 Share Posted April 16, 2008 I had the same problem trying to glue an earth magnet to the top of a preform container. Then I tried using Gorilla Glue. It works just fine and I havn't had a problem with it. Quote Link to comment
+The Pathman Posted April 16, 2008 Share Posted April 16, 2008 Gorilla Glue has yet to let me down but I haven't tried it with magnets Quote Link to comment
+Castle Mischief Posted April 16, 2008 Share Posted April 16, 2008 Gorilla Glue has yet to let me down but I haven't tried it with magnets From my own pre-placement testing: Gorilla Glue will still give you the same problem as super glue when it comes to attaching magnets to a semi-flexable plastic container. It dries rigid and will pop off if the container bends- like when you pull the container off the metal object you just stuck it to and the magnet really wants to hang on. I'd put the magnet(s) inside the plastic container and encase them in silicone caulk. Less chance of the magnets getting all chipped up when the finder re-attaches them to the metal object too.

+TheAlabamaRambler Posted April 16, 2008 Share Posted April 16, 2008 I love Gorilla Glue for most purposes, but it in fact does not flex well. Quote Link to comment
+briansnat Posted April 16, 2008 Share Posted April 16, 2008 Gorilla Glue has yet to let me down but I haven't tried it with magnets I have. Didn't work. Well it did for about 2 months, then the magnet came loose. Quote Link to comment
+scoutfrog Posted April 17, 2008 Share Posted April 17, 2008 What I use for my micros(bison tubes & pill bottles) is J B Weld 2 part epoxy. I use and old metal pie pan, flip it up side down and place a piece of paper on it. Stick the magnets to it and glue. I sand them first and apply glue to container then put the container on the magnet so the glue will encase it. A friend told me if they start to pop off to do what he does, He drills a small hole into the container first then force some glue into the hole and into the container where it will mushroom out and plug the hole plus hold the magnet.

+CSpenceFLY Posted April 17, 2008 Share Posted April 17, 2008 Clean the surfaces with laquer thinner and use Liquid Nails. Quote Link to comment
+Jolly Roger Posted April 17, 2008 Author Share Posted April 17, 2008 Thanks for all the advice! I think I will be trying the silicone caulk since I cannot seem to find a local store that sells marine goop. Quote Link to comment
