WarriorFish Posted April 26, 2020 Share Posted April 26, 2020 I'm familiar enough with using magnets but there's one thing I've not done yet and that is stacking magnets to create stronger bonds. I know it works of course, but I'm wondering how much? For context, I'm magnetising the snapping claws of my Keeper of Secrets because I don't fancy chartering a freighter for each game and while the join itself is straight forward enough it is a rather long arm and is almost horizontal: I currently have a 3x1mm N42 neodymium magnet in the shoulder and arm and the strength of their pull is good maybe enough... I would prefer that it was definitely strong enough so I won't have to worry about the arm getting knocked off during games. I could potentially rework the arm to put two of the 3x1mm magnets in on top of each other but what sort of improvement would I see?

armarnis Posted April 26, 2020 Share Posted April 26, 2020 Probably less improvement than a 3x1 at n52 Link to comment https://bolterandchainsword.com/topic/363481-magnet-stacking-power/#findComment-5512650 Share on other sites More sharing options...
WarriorFish Posted April 26, 2020 Author Share Posted April 26, 2020 Luckily I have managed to find a few 3x2mm magnets I didn't know I still had, but I have no idea what strength they are unfortunately. If I replaced the arm 3x1mm with one of these then even if it is another N42 it should make enough difference?

Fajita Fan Posted April 27, 2020 Share Posted April 27, 2020 You can stack magnets but you have remember to glue them together. https://www.kjmagnetics.com/blog.asp?p=doubled-forces This is where I order my fancier N52 magnets from (I get cheap magnets for my bases off Amazon) and they discuss this. Really neat site btw. Link to comment https://bolterandchainsword.com/topic/363481-magnet-stacking-power/#findComment-5513081 Share on other sites More sharing options...
WarriorFish Posted April 27, 2020 Author Share Posted April 27, 2020 Thanks Fajita, that is a very useful link! It seems I was mostly there with my understanding so it all makes sense I will try replacing the arm magnet when I'm next ready to do battle with the kit and of course report back here Link to comment https://bolterandchainsword.com/topic/363481-magnet-stacking-power/#findComment-5513182 Share on other sites More sharing options...
Fajita Fan Posted April 28, 2020 Share Posted April 28, 2020 I love these little guys, they're great for marine arms and tank barrels. https://www.kjmagnetics.com/proddetail.asp?prod=D201-N52 Link to comment https://bolterandchainsword.com/topic/363481-magnet-stacking-power/#findComment-5513349 Share on other sites More sharing options...
Xenith Posted April 28, 2020 Share Posted April 28, 2020 Pin to keep the arm in the right position and single magnet to hold it. I personally wouldn't rely on stacking small magnets for something like a long arm. Surface area of the magnet is what counts when it comes to shear-resistance. My long stack of 3mm magnets still breaks easily with minimal force.

WarriorFish Posted May 23, 2020 Author Share Posted May 23, 2020 Later than planned as I sliced my thumb when I attempted to return to try the new magnet, but as promised the results of using 3x2mm: Nice and secure Thanks for the help everyone, hope this can help someone else too :) Link to comment https://bolterandchainsword.com/topic/363481-magnet-stacking-power/#findComment-5526964 Share on other sites More sharing options...
Lord Ragnarok Posted May 23, 2020 Share Posted May 23, 2020 This is timely for me as I’m magnetizing leviathan dread storm cannon arms and they are a bit weak. I’ll try n52’s (if I can dig them out!)

Fajita Fan Posted May 25, 2020 Share Posted May 25, 2020 You may only need to replace a magnet on one side if you get N52s, they're stroooooong for their size!
